Hi,

I have GridViewTree on panel with ModalPopupExtender. When GridViewTree is open as modal popup, expanding nodes not working.
Click on 'plus' or 'minus' button on tree do nothing.
Without ModalPopupExtender the GridViewTree control working fine.

Code:

<asp:Panel ID="Panel1" runat="server" CssClass="modalPopup" Height="450px" Width="500px" >
<asp:Panel ID="Panel2" runat="server" ScrollBars=Both Height="400px" Width="500px">

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>

<GVT:GridViewTree ID="gvtZadania" runat="server"
AutoGenerateColumns="False"
DataSourceID="odsZadania"
FullPathDataColumn="Numer"

</asp:BoundField>


</Columns>
</GVT:GridViewTree>

<asp:ObjectDataSource ID="odsZadania" runat="server"

</asp:ObjectDataSource>


</ContentTemplate>
</asp:UpdatePanel>


</asp:Panel>

<br />
<div style="text-align:center">
<asp:Button ID="btnOK" runat="server" Text=" OK " />
&nbsp;&nbsp;
<asp:Button ID="btnAnuluj" runat="server" Text="Anuluj" />
</div>
</asp:Panel>


<cc1:ModalPopupExtender ID="ModalPopupExtender1" runat="server"

Please help me to solve this problem.

Hi,

I put an update panel inside modal's target panel, put the GridViewTree in the update panel. I have the script manager on master page, but script manager does not have "partialpostback" property. Is only EnablePartialRendering, but is set true. Expanding nodes still not working. Where do I set "partialpostback" property?


Lukasz.

Hi,

I suppose this isn't postback problem. I put GridViewTree on panel with ModalPopupExtender (without update panel) and when I click on fourth node to expand it, I have an exception - "Index 3 is negative or greater than the number of rows."





I check in Firebug and when GridViewTree is on UpdatePanel this exception appears too. This exception is always when I click to expand nodes.



RowCommand in GridViewTree working fine with ModalPopupExtender.

Hi,

I solved this problem :)
I set ModalPopupExtender target panel visible to "false". When I use ModalPopupExtender Show() method I set visible to "true". This make GridViewTree working fine :)

Thanks for your help.
