.NET Forum / ASP.NET / General / October 2007drop down list events
I have 2 drop down list; my first ddl contains the list below: A10 A20 A30 A40 A50 Those data were populated from the database. My second ddl will display the data according to what user choose from the first ddl. I'm using the selected index changed event to call a method which will go to the database and get the data from. My "problem" is when I select the first one A10 it will not trigger the selected index changed. I know that the index didn't change, but I was wondering if there are a way to trigger this event or I can call my method when the user click on the ddl even without the index change. Cheers! Claudi Try preset SelectedIndex to -1 on page load.

Claudi Another option is to add an empty item. In 2.0 you can do it without writing any code: <asp:DropDownList ... AppendDataBoundItems="true"> <asp:ListItem Value="">Please select item</asp:ListItem> </asp:DropDownList> SignatureEliyahu Goldin, Software Developer Microsoft MVP [ASP.NET] http://msmvps.com/blogs/egoldin http://usableasp.net >I did what you said, set the index to -1.. and it doesn't work.. is > still no trigger the event [quoted text clipped - 4 lines] > > *** Sent via Developersdex http://www.developersdex.com *** This ddl is populated according to what user chose from the previous ddl.. so how can I display the select from list as the first one? Is always something else.. I have to display other than the Select from... Cheers! Claudi
