Hello All
I have two drop down list in my page. When i select one drop down, the value of second drop will change according to the value of first drop down. I don't want page refresh when i select my first drop down. So i use update panel but now when i select the value from my first drop down on the event of selectedindexchanged it will always shows me the default value and if i remove update panel it works perfectly but with page refresh. I don't know what is the problem. Values for both drop down is coming from database. Also i have done !IsPostBack in my page load but i don't know where is the problem..
Please check the code below:
<td align="right" valign="top" style="width: 20%"> <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional"> ...

Go to the complete details ...
