hi Ajax Experts,
I have Search form with LastName, FirstName, Department, Institution, keywor, publications, Search Button(onclick), few gridviews,
all these controls are inside updatepanel
issues with updatpanel
1. whenever postback occurs hyperlinks in the gridview controls are loosing, i can only see texts with links.
2. I am trying to enable a master page asp panel when search results comes up. but its not working, i know bcoz masterpage asp panel is out side of this
updatepanel. And also masterpage asp panel contains a update panel too.
How can i resolve this issue? really i appreciate if any one can help me in this.
here is my aspx code
1 <asp:UpdatePanel ID="upnlSearch" runat="server" ChildrenAsTriggers="true" UpdateMode="Conditional">
