Hello Mats,

Which version of RadGrid are you using? I'm using the 2009.1.311.20 version and i could not replicate the issue. You can set the width of the Expand column in the grid to a fixed value using the following code:
c#:

    
             protected void RadGrid1_ColumnCreated(object sender, GridColumnCreatedEventArgs e) 
        
                { 
        
                    if (e.Column is GridExpandColumn) 
        
                    { 
        
                        e.Column.HeaderStyle.Width = new Unit(60); 
        
                        e.Column.ItemStyle.Width = new Unit(60); 
        
                    }   
        
                }

Thanks

Hi Princy,

Thanks for your quick answer. The version I use is 2009.1.527.20. But I have tried earlier versions of 2009.1 with the same result.
Adding your code to my project makes no difference to the visual rendered result. I can see in the html source that the width style is applied but it does not visually change anything.

I append here my (simplified) default.aspx for replicating the problem:

                    l.Add("Three");  
        
                    ((RadGrid)source).DataSource = l;  
        
                }  
        
                protected void RadGrid1_ColumnCreated(object sender, GridColumnCreatedEventArgs e)  
        
                {  
        
                    if (e.Column is GridExpandColumn)  
        
                    {  
        
                        e.Column.HeaderStyle.Width = new Unit(20);  
        
                        e.Column.ItemStyle.Width = new Unit(20);  
        
                    }  
        
                }  
        
            </script> 
        
            </html>

Interesting is that there must be some change from 2008 to 2009 since I never had this problem before.

Thanks
Mats
