I have a combobox on a form with the dropdownstyle set to drop down. Users can either salect a value from the list, or type in any value they wish. This all works fine. However, when one particular item in the list is selected I wish to set a different value. Unfortunately I don't appear to be able to set the combobox Text property from within any of the events that fire when the selected item is changed.

I have a combobox linked to a table Checklist (ID, Checklistname, and several multivalued fields). I want to have my subform display data from different tables based on my combobox selection "checklistname". All the tables are imported Excel files with the same fields and field types (ie. Discrepancy, reference, reference paragraph, category). How do I get my subform to requery based on the combobox selection? Or is there another method when working with "outside tables"? Import good/bad? Make new table? I have about 20 tables, if importing but only need particular data to save/store in my main table, and I need to know which table it came from.

View 8 RepliesI have a calculate function that adds twenty text boxes together a+b, etc... 20 +20, B changes value when a selection in combobx is changed, how can i make the calculate funtion work up selection change in combobox ? You would think the selection change or index change , but that doesnt work because the tetbox doesnt actually get the new value till after the combo selection is made, so you actually have to go and make the selection twice I know i can put the code in the textbox value change , but i dont want to do that for 20 text boxes and i am assuming there must be a BETTER way?
View 1 RepliesI'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.

View 2 RepliesI 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 data, i As Long, j As Long

I am new to vb.net and I am using visual studio 2010. I have two comboboxes on a form, each combobox is set to DropDownList so that a list of items can show in the combobox, but no text is allowed to be entered.
For combobox A, if user chooses item 1, the list of combobox B should be updated accordingly. I think this is quite common on a lot of applications. But I do not know to implement it. I even do not know the keyword to search for the relevant property or event handler.

View 2 RepliesIs it possible to have a different selection of values in the 2nd combobox depending what was picked on the first combobox? For example an American state is picked in the first combo box and the second combo box loads the cities in that state? I'm just using a basic form in Visual basic 2010 there is no database behind it.
View 6 RepliesI have a vb application sitting on an sql server with 4 different tables. I want a scenario where when I select any table from the combobox, every query I will run should use that table as a reference.

If A is selected then
SQLQuery="Select * from A "
If B is selected then
SQLQuery="Select * from B " etc
On my form I have three fields and a datagrid view.One field is a combo box.All fields are databound.The datagridview is a detail grid, bound in the "normal" way. Scrolling through records, etc., all work fine.What doesn't work is when a selection is made using the combo box.The underlying table has a self-join of one-to-many: ParentID, ChildID. ChildID is the main ID for the underlying table.Children may have a parent This is just by way of example.So, the combo box's Value is bound to ChildID, and the SelectedValue is bound to the ParentID.On the form one chooses the Parent with this combo box.When I test this arrangement, I select a Parent, then click Save (using the default toolbar actions). However, the combobox seems to "reset" the selection to the first in the list.

View 1 RepliesI have a combo box that has multiple options, when the user selects one of the options (world wide city destinations) a specific value is assigned to a variable. For example if "New York" is selected the variable "x" is assigned the number 155.

At the moment I am using:
lblOutput1.Text = "bla bla bla " + cmbDestination.SelectedText + " bla bla bla " + Today()
How can i bind a comobox selection to a datagridview without writting code...
i Need to select an item from a combox and based on that item refresh the datagrdiview. I did something like that in Access but i don't know how to make it work in visual studio 2008.
once i select the datagridview itme that i want to edit i'd like to be able to update back to the database. I know i need to write code for this but at least i'll have the data refreshed on the datagridview.
I have an app I'm working on with multiple forms. One of the forms, frmLocationInfo, has textboxes and comboboxes which are automatically populated based on a combobox selection from a previous form, frmLocations. I've been able to get any changes made to frmLocationInfo's textboxes to save to the SQL database, however, when attempting to select a different item from any of its comboboxes, it's not saving to the database and instead, I receive a "Procedure or function...has too many arguments specified" error.
Here is the code for the Save button:
'Save changes to Locations db
Private Sub btnSaveClose_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
