I had an issue yesterday with a dropdown on a form. I was trying to post the values to a new form. All the values would post fine except this one dropdown. I was racking my brain. What was happening is everytime I submitted the form, the value of the dropdown (varname.SelectedItem.Value) would be item[0] no matter what I choose!? This was driving me crazy because all the other form variables were passing just fine. I even had another dropdown that was posting fine. This one was giving me a problem. What was the difference you may ask? The only difference was that the dropdown that was not passing correctly was dynamically populated by a databind. Well, it turns out, which now makes sense, is that when the page posts back, the original value is sent. This happens because the page load function runs first on post back. Hence the default value being posted. What you have to do is this;
If Not Page.IsPostBack Then
varname.DataSource = DataTable
varname.DataTextField = “value“
varname.DataValueField = “value“
varname.DataBind()
End If
Adding these two lines of code around my databind worked wonders. It’s the small things that count. Keep your eyes open and as always, if there are any questions or suggestions, they are welcome. Thank you.
