[2005] How to catch combo event.

Hi All,
I m facing a problem in catching the Combo Event which i have placed in <asp:DataGrid> tag. i want some database operations to do on its change even but i m not able to catch its Event.

so please could u suggest some or the other way to achieve that ????

If you are using a template field go into the source view, and try setting the OnSelectedIndexChanged="functionName" property to the name of the function that you want to call. Make sure to set the autopostback="true".
