How do I recognize dynamic buttons as triggers for updating updatepanels?

I have two updatepanels on a page each with a datagrid inside the panels. I need updatepanel B to update it's datagrid when a LinkButton is clicked inside udatepanel A's datagrid. The linkbuttons are dynamically generated for each row of the datagrid.

Thanks

Stripped Down Example:

<asp:UpdatePanel id="pnl1" runat="server">
<ContentTemplate>
<asp:datagrid id="dgA" runat="server" > ... <asp:LinkButton ID="lbtnSelect" CommandArgument=' ... ' runat="server">...</asp:LinkButton> ... </asp:datagrid>
</ContentTemplate>
</asp:UpdatePanel>

<!-- Next Panel -->

<asp:UpdatePanel id="pnl2" runat="server">
<ContentTemplate>
<asp:datagrid id="dgB" runat="server" > ... </asp:datagrid>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="lbtnSelect" EventName=" ... "/>
</Triggers>
</asp:UpdatePanel>

Unless I misread your post, I think that all you need to do is add the following line inside of your event handler for the link buttons (lbtnSelect_Click, or similar):

pnl2.update();

This should update your pnl1 because the linkbutton's click event fired inside of pnl1, andprogrammatically updating pnl2 with pnl2.update() should take care of updating the other datagrid (dgB). You can get rid of the <Triggers> definition too.

How do I extend a DataGrid/DataList for ATLAS behavior?

I have two inherited DataGrid and DataList classes that render a paged grid and list with some enhanced behaviors (better pagers and retreiving only items that are shown with NHibernate). I would like paging not to refresh the page.

It's easy with an UpdatePanel: add a panel, add an event OnDataBinding( ) and Update the panel. For my project (www.foodcandy.com) this means updating a hundred grids and lists.

So instead I would like to build the panel behavior into the actual DataGrid and DataList and have all my grids behave this way. The first easy thing is to add a panel property and tell the grid/list that it's inside an update panel. But I still have to modify a 100 pages to add the update panels.

How do I do something like that?

Thx

hello.

maybe building a usercontrol will be the faster way to get what you want...though i still think that i'd add the panel to all the pages..

I doubt it will be faster Luis - this is a datagrid, I would need to expose all the methods for various properties like PagerStyle and I am not even sure what to do with ItemTemplates. No?

hello.

well, i was thinking in adding a property to the usercontrol that lets you get a reference to the datagrid.

I haven't tried this, but can you nest this in the aspx pages by having MyUserControl expose the DataGrid member?

<MyUserControl>
<DataGrid>
<TemplateColumn ... />
</DataGrid>
<MyUserControl>
