DropDownList SelectedIndexChanged not getting fired

ASP.Net: DropDownList's SelectedIndexChanged event not firing

I created a new ASP.NET default website from Visual Studio. I have used a drop down list control on my .aspx page and set the data source for it, which is working fine.

However, I need to use the SelectedIndex_Changed event for this DDlist, which is not getting fired due to unknown reasons. I have tried putting breakpoints inside the event, but it doesn't even fall inside the function.

Any idea what could be wrong?

Did you set it's AutoPostBack property to true? – user1227804 Feb 28 '12 at 11:09 — user1227804, Feb 28 '12 at 11:09

Just check that have you put AutoPostBack="true" in dropdown!

Assuming you haven't changed the AutoPostBack property to False, make sure that your databound ListItems have unique values. Also, the event is SelectedIndexChanged, not SelectedIndex_Changed,
