VB: Combo Box Text Disappears On Selected Index Change

[thechris]

Hi,

 

In VB I have a combobox with a default text value, "options". When the form is dropped down, naturally, an item can be selected from the combo box. A procedure is called on SelectedIndexChanged. However, nothing is shown in the text area of the combo box after an option has been selected. I want it to display the value the user has selected, but it is just blank :p

 

What am I missing?

 

It's worth mentioning that I'm pretty new to VB, and programming in general.

 

Any help would be greatly appreciated, thanks in advance.

Do you handle the SelectedIndexChanged event? If so, what do you have for code?

Hi, thanks for your reply.

 

My code for the event is as follows:

 

Private Sub ComDay_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComDay.SelectedIndexChanged
       Call CalculateDays(ComDay.Text, ComDay2.Text, ComDay3.Text)
   End Sub

 

I think this is what you require :p

 

It is the ComDay combo box with which the text is not present. The procedure called is a calculation of the parameters passed to it (and does not return a value).

So, what do you have for code inside of the CalculateDays? Also, as a quick test, find the value of ComDay.Text immediately before the call to CalculateDays. Hint: MessageBox.Show(ComDay.Text)

:)

Fixed :p

 

I was so sure it was nothing to do with the procedure (and posting is my last resort after fixing all the problems I can). Turns out the were some unwanted .Items.Clear in there. Deleted them, and what do you know, it fixed the problem!

 

D'oh! Sorry about that. Thanks a lot for your help anyway!
