VB .NET:  Programmatically set ComboBox selection

Suppose I have a combobox control in VB .NET that is assigned to a DataSource:

'ae.fnReturnAEList.Tables(0) returns a DataSet object
ComboBoxAELookup.DataSource = ae.fnReturnAEList.Tables(0)

Then the end-user types something in the ComboBox that is not in the list.

Since the value typed in is not in the list, an error results.

What I would like to do is default to the first item in the ComboBox (whatever that might be).

Thanks,

Tom

This would happen when the Focus leaves the ComboBox.

Can you change the DropDownStyleProperty to "DropDownList"? That will prevent anything from being entered that is not on the list.

You can also choose the first item as the default by setting the SelectedIndex property to 0.

I am not sure if the business rules allow me to set the style to "DropDownList".  I'll check on that.

For now I went with you second suggestion.

I actually found this on my own while waiting for a resonse, but it will be nice to have this question captured for future reference.

Thanks,

Tom
