Hi,
 I have a datagrid for mesage board admin and in the footer temlpate I have 2 dropdownlists where first drop down list is category and 2nd drop down list is topics. So when user selects a category I want to load topics related to the selected category in the second dropdown, so that user can select a topic in a category and add new message. But when I set autopost back true to category its posting back but as the categorylist is not declared in the codebehind(VS.NET and VB.net)I cant get to do anything? Any ideas?

You should be able to specify the postback handler for the dropdownlist in the markup for it in the grid footer template. Then you can handle the event.

Thanks Peter. But can you send me some example. I found add handler method which should be used in this case. As I am new to .net it seems bit confusing. Please can you send me some code example?

Try the OnSelectedIndexChanged attribute in the control markup.

<asp:dropdownlist OnSelectedIndexChanged="myHandlerMethod" />
