Any action from grid result a blank page

[Hans van Rijnswoud]

Hi,

I implemented a Grid inside an Iframe.
The grid is correctly showed inside the iframe.

But, for exemple, i want to navigate inside the grid with the pager or if i want to edit a record, i see wel the loadingpanel but after is the result a blank page inside the panel.

Any idee about this problem ?

Here is the code:

 

<form id="mainForm" runat="server">

 

 

<asp:Panel ID="PanelBody" runat="server" SkinID="PageBody">

 

 

<asp:Panel ID="PanelTitle" runat="server" SkinID="PageHeader">

Hello Edwin,

I suspect that there is a problem with the way the control is bound to data. I see neither NeedDataSource handler attached, nor a DataSource control used. Please, use one of these options to ensure that the control structure remains consistent.

Hi Yvor,

Right, i was forgot the RadGrid_NeedDataSource.
Thanks for your help.

I will try to found the time to learn a little bit more how to implement your product in my software because your sample are not enough complete or not very clear for me.
