Updating Gridviews

I need to update a gridview with another gridview, but I can't figure out how to do it.

I've got the AJAX component installed and it looks easy, but I can't find the right combination to make it happen.

I want the 1st control to look like this on the page...

item1

item2

item3

then when I choose one of them, I want it to update the gridview beside it.

Right now, I'm playing with the selected properties, but don't seem to have much luck.

Can anybody help me with this? it works just fine with other controls, but not with the gridview. And I know there's just something simple I'm missing.

thx.

Hello,

I would suggest using nested update panel controls. Put the second grid in one update panel, and then put both grids in new update panel. Then just put the event on wich you want the second gridView to update to the triggers collection. Example athttp://www.asp.net/AJAX/Documentation/Live/overview/UpdatePanelOverview.aspx section "Using nested UpdatePanel controls".

Use a DragPanelExtender and an AlwaysVisibleControlExtender component at the same time pro

<asp:Panel ID="Panel3" runat="server" Height="3333px" Width="3333px">
 <asp:Panel ID="Panel1" runat="server" Height="150px" Width="125px" BackColor="black">
 <asp:Panel ID="Panel2" runat="server" Height="25px" Width="125px" BackColor="Blue">
 </asp:Panel>
 </asp:Panel>
</asp:Panel>
<cc1:DragPanelExtender ID="DragPanelExtender1" runat="server" TargetControlID="Panel1" DragHandleID="Panel2">
</cc1:DragPanelExtender>
<cc1:AlwaysVisibleControlExtender ID="AlwaysVisibleControlExtender1" runat="server" TargetControlID="Panel1">
</cc1:AlwaysVisibleControlExtender>

I use a DragPanelExtender and an AlwaysVisibleControlExtendercomponent at the same time.
It works perfectly if I don't scroll the web page.
After I scroll the web page, the drag and drop behavior notworks properly. When I drag the Panel2, the Panel1 will disappear until I dropthe Panel2, the Panel1 will appear again.
Does anyone know how to solve this problem?

Hi Vincent901529,

I have tested your sample and I think this issue is cuased by the scroll offset. I suggest that you should post it to CodePlex. If you insist on resolve it by yourself. We suggest that you should move the Panel to its right place on its mousedown event. You can modify on the mouseDownHandler (Line : 140 V11119) in the FloatingBehavior.js under the DragPanel directory.

 function mouseDownHandler(ev) { window._event = ev; var el = this.get_element(); if (this.checkCanDrag(ev.target)) { //new added logic.

 .... ; // calculate the new location.

$common.setLocation(el, newLocation); // reset the showing position.

 _dragStartLocation = $common.getLocation(el); ev.preventDefault(); this.startDragDrop(el); } }

  Best regards,

Jonathan
