Create A Select All Filter In Combobox?

Oct 18, 2009

I am making a combobox dropdown to filter a report. I am using the table adapter to query the data and fill the report from the selected item in the combobox. However, if the user select index 0 (which is "-Select User-") , then the query should disable the filter and select all users in the database. How would I go about doing this with these 2 conditions?

Filter Combobox Contents By Text In Another Combobox

Jun 22, 2010

Brand new to VB 2008 Express, but have done some work in VB 6. Not sure what I'm missing, but here goes. I have two comboboxes linked to an Access 2007 database. One box lists the names of the States in the US.

This is what I used for the Table Adapter Configuration Wizard for the combobox "State" SELECT ST_UID, ST_NAME FROM STATE

For the combobox County I used: SELECT ST_UID, CTY_NAME FROM COUNTY ST_UID is an Integer.

I created a label with a bound value to STATE.ST_UID so that when a user selects the name of a state from the State box the appropriate ST_UID populates the label, (i.e, California has an ST_UID = 5).

The problem is when a state is selected, I only want the Counties for that state to appear in the County box, i.e, COUNTY.ST_UID = 5 if California is the selected state.

I then tried to convert the value in the st_uid label to an integer:

CODE:

This is what I last tried when again using the Table Adapter Configuration Wizard for the table that populates the County box: SELECT ST_UID, CNTY_NAME FROM COUNTY Where ST_UID = 'StUID' Order By st_uid, cnty_name

What I'm getting is a "Data type mismatch in criteria expression." I'm sure my error is something so simple.

Select Column With Filter Criteria Within A Row In A .Net DataSet?

Jul 27, 2011

I'm writing an app for someone where I am pulling in work orders table information. The information includes: worknum, fname, lname, customername, description, etc. I do not plan to update the data in this table, only to read from it.I'd like to display a combo box for the work order numbers. The user would start typing the information for the work order in and it would autocomplete based on what's in the list. As work orders are displayed in the combo box, I want to update the data in text boxes representing the various fields.

I'm thinking rather than query the database several times, it would be a good idea to create a DataSet with information for the work orders table within the last x months then query the data from that dataset. I know there is a DataSet.Select method, but it looks like it returns the entire row. Is it possible to retrieve just a column of distinct values? For example, I'd like to do a select statement similar to this:

SELECT worknum FROM {WorkOrderDataSet} WHERE date >'{today-x}

The first part in curly brackets is meant to represent the work order dataset I create when first importing the data from Access. The second part in curly brackets will be replaced with variable data to represent a date to reference. I also don't think I'll need distinct because the workorder is unique (edit: is a primary key)Is it possible to retrieve just a column of distinct values from a DataSet with multiple columns? How do I do this?

Access DB, Using Combobox To Filter

Feb 15, 2012

I got my regular fields like firstname,lastname, gender, birthyear, street, city, zip, phone. Which i can search through by just entering one of these fields.

Then i got a dropdown box which i was hoping to use a filter on. Every file is in a cabinet, but since those are somewhat alphabetically i have more then 1 cabinet for certain letters. This is why i wanted to use a filter to get a list of all people in a certain cabinet.

So i want my dropdownbox to automatically show the cabinets that are in the database(for example A...Z). If i choose B from the dropdownbox i want to see all the names that are in that cabinet in my datagridview.

Combobox - When Select A Value From The Combobox The Selection Won't Validate?

Feb 22, 2012

I'm having a problem with combo boxes. I usually use Java and it's been awhile since I used VB but I never remember having this much difficulty.My application is using an SDF file. From Data Sources, I drag the details on one of my Tables to my Form to get all of the fields. Three of them are comboboxes. Each of the three is an INT64 and each corresponds to a primary key in a different table. I click the tasks button on a combobox and for data source I select the appropriate table that has the data to go with the combobox, for display member I select the field that I want users to see, and for value member I select the primary key. Then I run a quick test and start the app, open the form, and add a new record. When I select a value from the combobox the selection won't validate because it doesn't think it's an INT64 like it should be. It seems to be using the display member as the actual value instead because if I change display member to the primary everything works great.

Select A Particular Value On A Combobox By Looping Through Combobox Items?

Jan 5, 2012

I have a form in my vb.net application used to take the data about the returned stock. The form contains two comboboxes. One, named combobox5, contains invoice numbers and the other, named combobox3, contains party codes. Both the comboboxes are pre_loaded using sqldataadapter.

Now what i want is to change the party code in combobox3 when the invoice number is changed in combobox5. Elaborating it further, When Stock is issued the party code is stored along with the invoice number to keep track of to which party was the stock issued. Now when stock is returned i want to keep track that which party has returned the stock and i want that the party code should be automatically selected when the invoice number is changed and it should be what is stored in the database against that particular invoice number....

I'm using the following code for doing so:

Private Sub ComboBox5_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ComboBox5.SelectedIndexChanged
' defines a new connection to the database
Dim con As New SqlConnection("Data Source=TAHA;Initial Catalog=ADT;Integrated Security=True")

VS 2010 - Any Way To Filter DataGrid Using ComboBox?

Nov 6, 2011

Kinda new to working with wpf apps (and vb.net). Looking for a way to filter a datagrid using a combobox (to select the field that the user wishes to search) textbox (to input search terms for specific records). The datagrid loads fine as does the combo containing the fields, however my filter simply does not work.

Code for loading data (works fine)
Dim obj = Me._dataManager.Collections.ReturnCollectionByID(tableSelectionCombo.SelectedItem.TableID)
Me.DataGrid.ItemsSource = obj
obj.Load(New DataManagementDataRequest(Nothing, Nothing))

Code for filtering (not working)
If Me.searchTxt.Text IsNot Nothing Then
obj.filter = selectFieldCombo.SelectedItem.ToString Like searchTxt.Text.ToString
Else
obj.filter = ""
End If

Filter A Datagridview From A Separate Combobox Selection?

May 19, 2008

I have a datagridview (datagridview1) on my form which onload displays all the records from the bindingsource (bindingsource1) via an sql connection to a table in sql server called "article".

I also have a combobox on the same form which displays the name column from the same "customer" table -

Me.ComboBox1.DataSource = customerTable
Me.ComboBox1.DisplayMember = "custname"
Me.ComboBox1.ValueMember = "custid"

I would like to enable my combobox to filter the datagridview via itsSelectedIndexChanged event . So if custname "xxxone" is selected in the combobox then the datagrid shows only the results for custname "xxxone".

So far I have worked out how to enable the combobox to move to the position in the datagridview depending on which custnameis selected-

Me.myBindingSource.Position = Me.ComboBox1.SelectedIndex

But this method still shows the other titles,it doesnt filter them out, it just points to the selected custname. I cannot find how to filter the datagridview so ONLY the selected custname is shown.

I will be changing the field names, I have used custname and custid just to describe what I am trying to do.

Filter ComboBox Data [2010 Express]?

Jan 7, 2011

I have started a form application using visual studio 2010 express, vb programming. I'm using Access as my database.My goal is to have ComboBox1 display a ProjectID and ComboBox2 display a TestNumber. Once the Test Number is selected I want my textboxes in the form to display fields from the row that the selected Test Number is in.I have 2 tables set up right now "Projects" and "TestData". The "Projects" table has a [ProjectID] field, the remaining fields are just misc. project data. The "TestData" table also has the [ProjectID] field, and then the [TestNumber] field, then the remaining fields are misc. data.

Filling [ProjectID] in textbox1 is easy, in the properties I select DataSource from the Projects table, display [ProjectID] field. Where I'm having troubles is ComboBox2 displaying the TestNumber from the other "TestData" table. If I select that field, it fills the ComboBox with EVERY TestNumber there is. So for Project 1 there is a test 1... over 500 projects, that combobox lists 500 Test 1's, no way to tell what project it belongs to...How do I make ComboBox2 only display Test Numbers that pertain to the Project number selected in ComboBox1?Using this code I can get it to work:

Dim ProjectNo, SQLString As String
Dim dtTableData As New DataTable()
Dim dbDataAdapter As OleDbDataAdapter

[code]....

I also imported system.data.oledb Problem with this code is it will only filter data in ComboBox 2 but when you make your selection from ComboBox2 it won't activate the row so none of my databinding textboxes fill anymore. Before the code/query is ran it fills up the textboxes perfectly after every selection I just have no idea what project that report number belongs to because the whole field is displayed in the dropdown. I can fill the form with ComboBoxes and they display the corresponding row data because I use a "datasource" instead of textbox "databindings" but I don't want to use 20 comboboxes as my entry form...

Filter Datagrid With Combobox And Prevent Doubles

Mar 15, 2012

I'm trying to create a Select Distinct query, but i'm getting stuck with either an empty combobox either a filled combobox that displays all the doubles.or a message "System. Data. DataViewManagerListItemTypeDescriptor".I have a form (form5) with 1 combobox and 1 datagrid. The datagrid loads 5 collumns "ID", "firm", "Fname", "mname", "Lname".[code]I would like to select the firm from a combobox and filter the datagrid so that it only displays the selected firm and the people that are registred here. Furthermore i want the combobox that i use for selecting the firms to lose the doubles.I can load the datagrid and load the Combobox, but selecting is only pointing to the record (highlights in the grid) i chooses but doesn't filter.[code]I use the "Me.EmployeesTableAdapter.Fill" method so mu question is, is it possible that i don't need to use the OLEDB connection or do i still need this to correctly connect to the DB (access)? I changed the script that i brewed together as displayed above, but this did not do the trick.
