Dropdowns and selecteditem issues

[andycharger]

I have a dropdown list on my page and a submit button.

However, When I change my selection and press submit, it always takes the first value out of the list!

e.g. I have a list with 3 entries, Horsebox, Trailer and Car

Like this:

 

Horsebox

Trailer

Car

 

I select Car from the drop down and press Submit.

 

Then the page passes through the name in the url

 

i.e Department_Id="Car"

 

However, it always passes through the first value in the list and this is despite me setting the following code:

 

Sub Go_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Go.Click
       Dim strSelected As String
       strSelected = oDeps.SelectedItem.Text
       Response.Redirect("trainingplans.aspx?dept_id=" & oDeps.SelectedItem.Text)
   End Sub

 

any ideas why it is not taking the value I selected in the drop down box?

Are you populating the list in your form_load event?

 

If so you will need to check Page.IsPostBack - if it's true don't reinitalize the controls.
