Hi all,

I'm having trouble accomplishing a task in ASP.NET / C# and was hoping for some help.

I have an asp:dropdownlist, being dynamically generated from a DataSet [hitting a SQL Server] set to AutoPostBack.

The problem is that when the autopostback occurs the dropdownlist resets itself to the first index of the list.

So, in other words, if I have a drop down list with three items: Red, Yellow, and Blue

Every time I select my choice...say Blue...it does the autopost back, and I can grab the SelectedIndex [which is perfect for my backend stuff], but then the postedback page shows 'Red' again, and the user feels like nothing actually happened.

If I was to create the list items for the drop down manually, then this error does not occur. It ONLY occurs because the dropdownlist is being dynamically generated.

I have tried to grabbing the selectedIndex using Request.Form, but I don't know how to assign the drop down that SelectedIndex on the postback as it is being generated...

Does anyone have any suggestions or a solution? I would greatly appreciate it.

Thank you VERY much
-Mike

Hi Mike,

You may have more success posting this in the dedicated asp.net forums rather than the .asp forums.
