From one of my webpage, I am opening up another form as ModalDialog, and on this form, I have a Grid, Treeview and some other controls.
[Code]....
I have some code on click of Treeview Node, I fill out other data in Grid on click of Treeview Node.
Now the problem is when page posts back ( on click of Treeview Node ) , page flickers once during filling up data in Grid.
Basically whenever page.ispostback is true, page flickers, Now I want to avoid this.
I have to keep "SmartNavigation="false"" on this page because of some of the Treeview Problems.
Specifically on Node click of Treeview and on Update button press.
Call JavaScript function on GridView Row click using jQuery in ASP.Net works great!, but if I want to have a first column with an image button so the user can click only there to select a row it always produce a postback when using a button field, how can I avoid that postback while having an image button for the selection click in the gridview?

I'm having a really difficult time getting a DataList to work at all. When nothing is bound to the control (this happens before postback) I get an error.
<asp:DataList ID="ResultBox" runat="server">
<ItemTemplate><%#DataBinder.Eval(Container.DataItem, "Loc")%><br>
</ItemTemplate>
</asp:DataList>
I get the error: DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'Loc'.
I know it doesn't contain a property with the name 'Loc' because I haven't bound anything to the control, which I only do after hitting a Submit button and postback.
How do I get around this so it conditionally evaluates the DataList?
I have an AsyncFileUpload with an image control to show a preview of the pic that is uploaded. Everything works fine, however on the postback from the asynchFileUpload the page jumps to the top of the page and then after a second or two it goes down to the proper scroll position. What can I do to avoid having the page jump to the top and then back down again on the postback ?
