Forms :: Populate Textboxes Based On Combobox Selection NOT Using Databinding?
Apr 27, 2010
how to go about this? I have a form, frm1 w/a combobox, cboLocations, which is being populated using a sql string. There is also a frm2 w/a series of textboxes and other comboboxes. I want it so that once a selection is made from cboLocations, the textboxes and comboboxes on frm 2 are populated with the corresponding data. Here is what I have so far:
frm1:
Public Class frmLocations
Dim conn As New SqlConnection("Data Source=f03d3s-dev01; Initial Catalog=dos_track;User Id=vbuser; Password=tran3;")
Dim depot_refnbr As Integer
[Code]...
What's happening right now is that I make a selection from cboLocations on frm1 and click on the OK button, frm2 loads, but none of the textboxes are populating and one of the comboboxes, cboDepot, shows the different data when you click on the down arrow, but it's not displaying anything it its text field when frm2 loads.

I'm new to programming and I'm using vb.net 2010 and I'm stuck with this problem. So here are the details, I have 2 tables in my database, a product table and a category table. In my product table I have product no, product description and category no. In the category table i have category no and category desciption. So this is where Ive been stuck for the entire day, I want my combox(product) to populate based on what is in the combobox(category). For example I have "Chair" in my combobox(category), then what would appear in the combobox(product) would be "sofas", "dining chair" etc.'the part below is where the program will read the category description from my database
Sub fillcomboDesc()
Dim fillcatDesc As MySqlCommand = New MySqlCommand("Select catDesc from category;", connection)

I'm trying to populate textboxes on one form based on a selection on a combobox on another form. All data will be pulling from the same SQL table. I've got the combox to work fine to show the correct data in one of the textboxes by using the lines:
Dim connectionString As String = "Data Source=F03D3S-DEV01; Initial Catalog=dos_track;" _
& "Integrated Security=True"
[Code].....
,but not sure how to get the other textboxes to fill with the correct data (from the same SQL table row) associated with the combobox selection. I've spent SO MUCH time on this trying to figure it out, but am getting nowhere fast...

I have a database with table "Customer" that will be the datasource for my form controls. My form has a combobox and various textboxes that need to change based on the selectedvalue in the combobox, cboCustNo. Firstly, I'm try to get the combobox to populate with the customer names on the table but have the value member of the combobox set to their customer numbers (just for ease of indexing). Based on the user's selection I'm trying to have various textboxes show the corresponding data (Address, City, Balance, etc.). The code I have so far is below:
Dim cnnDB As New Data.OleDb.OleDbConnection
Dim cmdSelect As New OleDb.OleDbCommand
Dim rdCustomer As OleDb.OleDbDataReader
Dim CustTable As New DataTable

I have a product table with ProductId,ProductName,ProductCode as fields. I've populated a combobox with productnames. Next I have two other tables called Result_Header and Result_Detail. The Result_Header table has ProductId as a foreign key and BatchNo,TestDate etc. The Result_Detail table has ResultId as a foreign key which is the ResultHeaders Primary Key and other fields such as Result,SpecHi etc. What I need is when I select a Product from my combobox my two datagridviews must be populated via the Result_header and Result_detail tables respectively.

Visual Basic 2010 Express: I have a form with a combobox that is populated with the names of locations from a datagrid which in turn was imported at run-time (Form_Load) from an Excel database. The Excel database (and the datagrid) also stores the information for addresses and phone numbers for their respective locations.
What I would like to do is have the phone number and address text boxes automatically be updated with the proper corresponding data when the user selects a location from the combobox. Whether the text boxes are updated from the datagrid or Excel database is not a concern; I'm mainly looking for whichever way is simpler.

I'm rewriting a VB6 application in VB.Net. So far I have 2 forms, frmLocations (frm1) and frmLocationInfo (frm2). frmLocations has a combobox, cboLocations, from which a selection is made and an "Ok" button is clicked, which then loads frmLocationInfo. frmLocationInfo has a series of textboxes to display info corresponding to the location that was selected - Location, Location Number, Phone, Fax, Email. There are also 3 comboboxes on frmLocationInfo - cboDepot, cboFreight, and cboDispatcher. I need their text property along with items to be populated, also with data corresponding to the initial selection made on frmLocations. I'll spare you all the difficulties I'm having w/the other comboboxes, and instead focus on cboDepot. I have gotten it to populate its text property to display the corresponding Depot, however, the items are not populating and all you see now when you click on the dropdown arrow is only the depot that shows up in the text property.
Here is the code for this portion.
frmLocationInfo
Private Sub FillDepotCombo()
Dim sql As String = "Select distinct depot.depot_name, depot.depot_refnbr, locations.site from depot inner join locations on depot.depot_refnbr =

Basically it's choosing a line number on the first box and then selecting the machine associated with that line number.[code]...

Working on a project that contains a listView (populated from a database already) and several textboxes. What I am trying to do, and cannot figure out, is to program this so that when a user makes a selection in the listview, it hits a specific database, and based on certain values within that databse, the textboxes are populated with things such as name and address, etc..

I currently have a form with two comboxes. The first cbo is being populated with a project number, which is being pulled from the first column of a spreadsheet. I now want the second cbo to read the first cbo and then find that project number on the spreadsheet; when it finds that project number, I then need it to copy data from the row the project number is on. I have converted to vb from vba. Below is the code I used in vba (which obviously does not work). I only need certain cells from the project row.
Dim proj_num, rng As Range
Dim data, i As Long, j As Long

I have two ComboBoxes
<ComboBox Name="cmbMake" DisplayMemberPath="MakeName" SelectedValuePath="MakeID"/>
<ComboBox Name="cmbModel" DisplayMemberPath="ModelName"/>
I use LINQ-to-Entities to populate the cmbGroup ComboBox
Dim db as myDataEntity
cmbGroup.ItemsSource = db.Makes
How do I populate my second ComboBox (cmbModels) based on the selection of the first ComboBox (cmbMake) using XAML so that whatever I select in the first ComboBox automatically filters the ItemsSource in the second ComboBox?

I have VS2005, Microsoft Access 2003
ComboA is binded to the Customerstbl and displays the CustomerNames. ComboB is Binded to the CustomerContactstbl for the selected customer above and displays all Contacts for that customer is a second cbobox.
I am having a hell of a time with this, When I select a customers name in ComboA, I want ComboB to automattically query the contacts in ComboB based on ComboA's selection. where do I create the query for getting the contacts for that customer?
In the Customer or Contacts tbl?
Is this something that would be better hard coding or is VS2005 that much improved that its ok to use these binding features?

I am creating a program that will allow me to manage server EXE's for which I have the method to do so already completed. The problem comes when I want my front end to be able to use a database of different server configs stored in a dataset.
My Database has 4 columns (ServerID | ServerName | ServerPath | ServerMod)
I wish to be able to select the ServerName in a combo box (already done via Datasource/DataMember) and then load the ServerPATH and ServerMOD for that row into two variables.

I'm running into a little problem making one combo box dependent on the selection of another combo box. I'm using a access back-end to this project. I have two tables: MajorCategoryTbl and MinorCategoryTbl , MajorCategoryTbl has PK and description field, MinorCategoryTbl has a PK, MajorID (foreign key), and description field. I have two combo boxes on my form, one that displays the Major description, and one that displays the MinorCategoryTbl description, but the stored value is the PK for both. I want the selection of the minor category combobox to depend on what was selected in the major category combobox.

I'm writing a standalone application in VB.NET using Visual Studio 2005. I want to display/hide a bunch of Buttons based on the selected value of a ComboBox. Each selection would have a different set of Buttons to display, and I'd like to have them arranged in a nice grid.
Driving a TabControl with the ComboBox value would be the kind of behavior I want, but I don't want it to look like a TabControl to the user because it might be confusing.Is there a way to do this?
Basically, I'd like Selection1 of the ComboBox to show Buttons 1-4, Selection2 to show Buttons 5-11, Selection3 to show (maybe) Buttons 1, 3, 5, 6, and 8, etc., have them arranged nicely, and have the GUI show only the ComboBox and the buttons.

I am creating a document control system for standard operating procedures (SOP) in MS Access 2007. I have just started an online VBA class and have moderate MS Access 2007 experience. This thread is very detailed and lengthy.I have the tables set up and forms created for CREATE, SUPPLEMENT etc. I need to create a user interface so that when they open the database it pulls up a form that has buttons for "Start New SOP Process" and "Modify Existing SOP Process". Every step of writing an SOP is dated so that management can have outputs for target measures (to see why it takes so LONG to write an SOP from start to finish). After the user selects "Start New SOP Process" or "Modify Existing SOP Process" I am trying to have a Combobox appear with a drop down box of change types: CREATE, SUPPLEMENT, and REVISE.
Primary Key Explanation:Each document has a 3-part number comprising a 3-part PK. 1.001v1.0. Where 1 is (1-6) identifying what type of SOP: Document Type,.001 is the Document Series (a sequential number for each type of equipment--the 2nd SOP written for a document type 1 would be 1.002v1.0) and v1.0 is the version.
For example, lets say Document Type 2 indicates field equipment. The very first SOP written for a piece of field equipment would be 2.001v1.0. If a supplement is made to the SOP for that same piece of field equipment, then it becomes 2.001v1.1, if a revision is made to that same piece of equipment it becomes 2.002v1.0. If we buy a new piece of field equipment it would be assigned SOP document number 2.003v1.0.
After a document is changed (any part of the 3-part number is changed) the previous record is put into an archive table so that the technicians/general public have access only to the most recent version of each SOP. I am going to store them on Sharepoint with an Archive Folder and an Active Publications Folder and a link to the document is provided in the database. However, while a document is being modified (going through the SOP process of reviews and drafts) the users are going to need access to the previous version until the most recent version is approved (maybe I could have the document be archived upon completion of the Document Link control).
For each Combobox option I need a different "On Click" command to open the associated forms for each "Change Type". I have the necessary forms already grouped (using subforms and tabs) for each change type: CREATE SOP (has all of the forms needed when creating an sop), SUPPLEMENT SOP (has all forms needed when supplementing an sop), REVISE SOP (all forms for revising). I am trying to use If Then statements for this...
The modify part is the simplest. I think the Combobox for the "Modify Existing SOP Process" should consist of "Change Type" (CREATE, SUPPLEMENT, REVISE), "Document Type", "Document Series", and "Document Version". I want the "Change Type" to open up the correct group of forms with "Document Type", "Document Series", and "Document Version" finding the existing record that needs to be modified (i.e. so that the user can add dates for completed activities as the SOP process progresses: draft revisions, reviews).
The "Start New Process" is even more complicated. Each change type does more unique event procedures than just opening the forms (which I can't even figure out to begin with!!). The Combobox would still be "Change Type" (CREATE, SUPPLEMENT, REVISE), "Document Type", "Document Series", and "Document Version". However the following is what I am trying to do for each "Change Type":
When "Create" is chosen from the Combobox it will find the next record in the document series by the user selecting the correct "Document Type". I would like to add a formula so that it adds .001 to the previous record (giving the next sequential number), and force v1.0 to be entered and not able to be modified, since a newly created document can only be version v1.0. Then it would open the "CREATE SOP" form (all forms associated with "Create" compiled on one form by tabs and subforms--I already have this complete for each "Change Type") and require the user to fill out all document information controls (title, description, etc) before closing.
When "Supplement" is chosen from the Combobox it will find the most recent record by the user's input of Document Type and Document Series. I would like to add a formula so that it adds .1 to the previous Document Version. Then it would open the "SUPPLEMENT SOP" form. It would be useful if the fields for the document information controls (title, description, etc) were appended to this form but it is not necessary.When "Revise" is chosen from the Combobox it will find the most recent record by the user's input of "Document Type" and "Document Series". I would like to add a formula so that it adds 1 to the previous Document Version and forces the decimal value to be 0 (revise and create change types have to end in a "0"). Then it would open the "REVISE SOP" form. It would be useful if the fields for the document information controls (title, description, etc) were appended to this form but it is not necessary.Additional buttons I would like to have on the Main Menu Form--opened when the database is opened (includes "Start New SOP Process" and "Modify Existing SOP Process") would be:
"View All Publications" where a user can not edit anything, just gives them access to the current "active" SOP links. It would be a complete list of all of our SOPs. I think I could use a query "Retire" which would put an SOP into the Archive table/folder on Sharepoint. This would be useful in addition to the automated retiring of previous version in case we discontinue use completely of a peice of equipment or administrative procedures (yes we have SOPs for EVERYTHING!!)"Target Outputs" which would be a report showing the timeline of the SOP process so that management can see where we are spending too much time (my vote is for the design of the document control system!!)"Maintenance History" which would show all previous versions for each piece of equipment and administrative procedure."List of Archived SOPs"which would show all of our inactive SOPs, for the Quality Analysis/Quality Control person's benefit.

I have just realised that ComboBoxes don't have a Change event. I have a combobox filled with a few items, eg. Bakery, Deli, Fruit & Veg, etc. Choose one of these items, all the related items show in the dgv. However, when I blank the text in the Combobox (press Delete key whilst Combobox has the focus), what event fires so I can blank the dgv? The combobox does not contain a Blank item. Even if it does, the Blank item only fires the ComboBox1_SelectedIndexChanged when the user scrolls down to, or clicks on, the blank value.
I want to clear the dgv when the user blanks the combobox without necessarily changing the selection index.
