I've got an Access 2007 table with names of people and the unique ID # of their sponsoring agencies. There is a second table in the accdb with the sponsoring agencies and their unique ID #. How do I display the actual agency name, and not the ID #, in a combobox?
What I want to see is this:
John Doe ABC Corporation (John Doe in textbox, ABC in combo)
The results I'm getting is this however:
John Doe 10
I'm using the code below to display the agency and name. I know this is not the right code but don't know what other code to use.
DirectCast(e.DataRepeaterItem.Controls("cboSponsoringAgency"),
ComboBox).Text
= currItem("SponsoringAgencyID").ToString

I can use this code to set the DisplayMember, but the ValueMemeber is always the name of the field and not the field values. I can even reverse and put the ID in the DisplayMember and it works. Not sure what I'm missing here.

What I'm just trying to do is the following:I need to fill a combobox from a dataset, but I have to translate the entries before displaying them. That's why I assume I have to use a loop to add the Items.
View 2 RepliesI am using a bound combobox control in a vb.net application. How do I set the combo box to an item if I know the value of the ValueMember, but I don't know the DisplayMember. I can use the FindExactString method if I know the DisplayMember, but not if I only know the ValueMember.In explanation, the value member is an employee Number, the display member is the Name. I get the employee number from a detail item in another table and now I want to set the combobox to display the Name that goes with that detail item.
Can someone post some vb code to show how to do this.

I have binded a datatable to a combobox, using DataSource, DisplayMember and ValueMember properties. Now I try to set the combobox to a preset value using comboBox.SelectedValue = value. Nothing happens however.

I'm using this code:

cListItems.Add(New Combobox_values("One", "1"))
cListItems.Add(New Combobox_values("Two", "2"))

I have an editable ComboBox with a validation on the Text property to make sure manually entered info is valid.EDIT: All I want to do is populate the .Text property with the ValueMember of a selection rather than the DisplayMember I also have the .Items populated with valid entries having the DisplayMember and ValueMember set.My DisplayMember is a caption along with the data, and the ValueMember is the data itself.So Items might be:
(DisplayMember, ValueMember)
"Foo - 1ab2" , "1ab2"
"Bar - 3cd4" , "3cd4"
I had a validation on the text which can also validate manual user input like "5ef6" The problem I'm having is that if the user selects an item from the combobox it populates the text field with the DisplayMember property (ex: "Foo - 1ab2") which will fail validation.I have tried to manually set the .Text property with the SelectedValue or the SelectedItem.Value on each of the three relevant combobox events to no avail.I would like that the .Text of the ComboBox get populated with the .ValueMember of the item when selected rather than the .DisplayMember
EDIT: I cannot validate by trying to extrapolate the value from the caption. I send the Text off to a service to be validated.
void FillMyCombo
{
KeyValuePair<string, string> listValue1 = new KeyValuePair<string, string>("Foo - 1ab2" , "1ab2")
KeyValuePair<string, string> listValue2 = new KeyValuePair<string, string>("Bar - 3cd4" , "3cd4")
[code].....
The user can manually enter something like "5ef6" which will pass validation.But when they select an item from the list, rather than manually entering it, the .Text property gets filled with the caption and not the value ... so it will contain "Foo - 1ab2" and that will fail validation. I cannot change the validation method to "infer" the value from the caption. I have no control over that service. All I'm after is the displayed value EDIT: Say a user selects "Foo - 1ab2" from the dropdown list, I want the text in the box to say "1ab2" EDIT: I have also tried to set the .Text property in code but I can't seem to make it work in any of the ComboBox events. how to programmaticly set the .Text property (and make it commit!) on a selection event they will also answer this question.
Is there any way to get the ComboBox SelectedIndex based on SelectedValue when Datasource property is set with DisplayMember and ValueMember?
View 1 RepliesOk, I'm trying to set a value to each item in my combobox, but I don't know how. Lets say I have ComboBox1 that contains the letter A-Z, 26 items, I would want to set each letter a specific number, then use that number for something else. Like, if I set the letter A to equal the number 4, and the user has chosen A in the combo, I could do something like make a Msgbox say that value(4). Does that make sense?

View 7 RepliesI have a combobox called cbMaterialType on a windows form that's bound to a table in SQL - everything loads great and the combobox displays 'Material' items as it should, in that table I have two fields - Material (as mentioned above) which is a char(25) and InStock which is an nchar(1). If the InStock field contains a '1', I'd like the individual material to be green in the combobox, if '0', then red. I have the simple code in the drawitem event of the combobox as follows, but can't seem to get any results at all:
Private Sub cbMaterialType_DrawItem(ByVal sender As Object, ByVal e As System.Windows.Forms.DrawItemEventArgs) Handles cbMaterialType.DrawItem
If MaterialTableAdapter1.GetData.Item(cbMaterialType.SelectedIndex).InStock = 1 Then
cbMaterialType.ForeColor = System.Drawing.Color.Green
Else
cbMaterialType.ForeColor = System.Drawing.Color.Red
End If
End Sub
I've never worked with any form of color in comboboxes before and this is my first attempt at the drawitem event.

I have 13 variables, all called Items1, Items2, Items3 and so on. I have a combo box with items in, each time I click a button I want it so whatever is selected is stored in a variable and if the button is selected again then it stores whatever is selected in the next variable. I know all the code for selecting items in a combo box and transferring it to a variable but the problem I cannot do is the part where each time a button is clicked it stores whatever is selected in the combo box to the next variable.
