Hello

I have a RadGrid with one Group. The data is seperated by the groups in a proper way.
So from this point everything is ok.

Data should be added by an edit form (modal popup).
Now I try to display the edit form, but it's just appearing if I press "Add new record".
Pressing "Edit" in a row does not show the edit form.

If remove the grouping of the RadGrid, the edit form appears as expected!

What's the reason for this behaviour?

Here is my code:

    
                <asp:ScriptManagerProxy ID="ScriptManagerProxy1" runat="server">  
        
                </asp:ScriptManagerProxy> 
        
                <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">  
        
                    <AjaxSettings> 
        
                        <telerik:AjaxSetting AjaxControlID="gridMain">  
        
                            <UpdatedControls> 
        
                                <telerik:AjaxUpdatedControl ControlID="gridMain" LoadingPanelID="RadAjaxLoadingPanel1" /> 
        
                                <telerik:AjaxUpdatedControl ControlID="imgSearch" /> 
        
                           </UpdatedControls> 
        
                        </telerik:AjaxSetting> 
        
                        <telerik:AjaxSetting AjaxControlID="imgSearch">  
        
                            <UpdatedControls>

Hi CH,

It is very important that we replicate the precise settings, which demonstrate this behavior.
Attached to this message, you will find a small project, which handles a similar setup, and behaves as expected.
You can either use it to introduce any additional settings, which replicate the issue, or open a formal support ticket, and send a separate project.

Kind regards,

Hello CH,

As a quick follow up on the post which I made previously.
I further tracked the issue, and, depending on the number of records displayed, a similar issue to the one which you described is shown. This behavior is caused by a limitation in the rendering mechanism of the grid, introduced to workaround a bug in IE. One custom solution, which can be used to eliminate this behavior is shown in this forum thread:

http://www.telerik.com/community/forums/aspnet-ajax/grid/popup-form-template-is-not-appear-after-grouping.aspx

I hope this information helps.

I am having the exact problem as documented in this thread. I downloaded the WebSite1 example and was able to make is fail by adding the setting the property GroupsDefaultExpanded="False" in the MasterTableView.

I then modified the property on my form and still the edit form would not open. I then set the set the property GroupLoadMode="Client" in the MasterTableView and everything works!

I can run like this for the short term but as this form has the potential for displaying a large amount of information this needs to be addressed and sending everything to the client is not the solution.

Thanks

Tom
