asp: dropdownlist

[dhmfh]

Hi guys

I have a asp:dropdownlist control that is databinded. When I change the value it posts back and displays the selected value. When I click the search button it re-directs to another page and i lose the selected value. Any ideas of how not to lose this value

Pass it through to the second page as a session variable, a querystring or use Server.Transfer.

If you do not want to store data in the session, you could create the hyperlink you want to post to in the SelectedIndexChanged event handler of the drop down list. Then include the selected id in the hyperlink and access it in the page you are redirecting to:

eg:

int id = int.Parse( DropDownList1.SelectedItem.Value );
string url = "myUrl.aspx" + id.ToString();

Response.Redirect( url, true );

Page you are directing to:

int id = int.Parse( Request.QueryString[ "id" ] );

Hope this helps.

Thanks guys for these points.

On another note I am using a nested repeater that binds data through a relation to the dataset. Do you know how to reference values from the child repeater?
