Greetings,

The RadGrid's GridTemplateColumn seems to break between .NET35 and .NET4+.  Running the simple code below works fine for .NET3.5 and breaks for .NET4+, see the attached .PNGs.      

 Any idea why?

Thank you,
Gary.

Gary,



try this:



protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
 
    {
 
DataTable dt = new DataTable();
 
dt = GetSomeData();
 
RadGrid1.DataSource = dt.DefaultView;
        
    }




thanks,

Tried as you suggested.  Unfortunately, still didn't work.


DataTable GetSomeData()
{
    DataTable dt = new DataTable();
    dt.Columns.Add("ID");
    dt.Columns.Add("Name");
    dt.Rows.Add("1", "Gary");
    dt.Rows.Add("2", "Michael");
    return dt;
}
 
protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
{
 
    DataTable dt = new DataTable();
    dt = GetSomeData();
    RadGrid1.DataSource = dt.DefaultView;      
}

Hi Gary,

I have prepared a sample RadGrid web site to test the described behavior and it works as expected on my end. Can you please run the attached application and instruct me the exact steps I need to follow to reproduce the issue?

Hi Eyup,


The issue occurs when you add a GridTemplateColumn and use a DataTable for the DataSource.  My original post said "Framework Issue" because when I switched frameworks to 3.5, the Grid did not fail.  I should mention this occurs in VS2013 with .NET4+.  This error does not occur in VS2012 under any framework. 



At this point I believe there is a bug in the RadGrid (2013.3.1015) when using GridTemplateColumn with .NET4+ in VS2013 using a code behind generated datasourse.  I notice others have posted similar problems without resolution.



I've switched to VS2012 until this is resolved.



Thanks,

Gary.

Gary give it another try and make sure to debug=false this time.

Ok, that worked.  Do you consider it a bug in RadGrid that requires the "debug=false" workaround? 

Thanks!

Well, bug is an offensive word for a smart control like radgrid. It looks like a compatibility issue. :)
