Hi folks

I have got a very strange problem.... I developed my page using RadGrid which data binds on the client side using a WCF service. All worked fine on my local dev box so I checked in my code. However, the next day the testers report that it's not working.

When I look into the problem, it turns out that when the site is running in Internet Explorer (v6-8) under IIS, the RadGrid data binding doesn't work. The call to the WCF service never makes it to the server. What is even more annoying is that it is intermittent - I spent a couple of hours looking into it, then it started working. It then worked for around 24 hours then stopped working again. This has been going on for a week now! I have now managed to look into the problem for the last 3 hours today (without success) and it is still not working. The site is deployed on 3 different servers - it works on 1 at the moment, but not on the other 2.

It's driving me insane because it seems to debug into Telerik client side code, then I geta bit lost at this point.

Anyone got any advice?

Just to clarify.... it works 100% of the time when running in the Visual Studio web server, and also works 100% of the time in Firefox. The problem is specifc to Internet Explorer and IIS.
Also... some things worth noting... It's making it into the OnDataBinding event on the client side, so it seems to be going through the motions, but never makes it to the server. Also, the site is running in https - don't know if this affects things?

Thanks

OnNeedDataSource event doesn't fire

Hello,

I had my RadGrid with DataSourceID - from Database. The data displays fine.
My original goal is delete the recod on the server and I noticed the sample from Help.

<telerik:RadGrid id="RadGrid1" runat="server" OnDeleteCommand="RadGrid1_DeleteCommand"
OnNeedDataSource="RadGrid1_NeedDataSource">
<MasterTableView AutoGenerateColumns="False" DataKeyNames="CustomerID">
<Columns>
........
When I tried to use that, the application never fires OnNeedDataSource event,
so my Grid is always empty .

Did I missed something or this code sample is not complete.

Please help

[Solved] Return cell.innerHTML (row value) when using card view

Hi,

I'm using a RadGrid in Card View as shown in your demo's Grid CardView Demo. This works great and gives a nice look to my application. But I'm struggling to return the clicked row's data key. My normal approach would be to expose the unique cells innerhtml but with the itemtemplate I'm getting the full cardview html.

    
            <telerik:RadGrid ID="InstancesGrid" runat="server"  GridLines="Horizontal" 
        
                OnNeedDataSource="InstancesGrid_OnNeedDataSource" Height="50%">  
        
                <MasterTableView AutoGenerateColumns="False" CellSpacing="-1" DataKeyNames="instance_id">  
        
                    <RowIndicatorColumn>

                    <ExpandCollapseColumn> 
        
                        <HeaderStyle Width="20px" />

            </telerik:RadGrid>

    
                    function InstancesGrid_OnRowClick(sender, args) {  
        
                        var index = args.get_itemIndexHierarchical();  
        
                        var MasterTable = sender.get_masterTableView();  
        
                        MasterTable.selectItem(MasterTable.get_dataItems()[index].get_element(), true);  
        
                        var selectedRows = MasterTable.get_selectedItems();  
        
                        var row = selectedRows[0];  
        
                        alert(row);  
        
                        var cell = MasterTable.getCellByColumnUniqueName(row, "instance_id");  
        
                        alert(cell);  
        
                        var instance_id = cell.innerHTML;  
        
                        alert(instance_id);  
        
                    }

The alert(instance_id) returns the full itemtemplate html :-

<IMG id=InstancesGrid_ctl--_ctl06_iconImage ....>

All I want is the data key (instance_id) for the record in the selected row.

Thanks
Jase
