Hi,

Please I have 2 questions in RadGrid:
First : My grid have many columns and there width become very wide (about 2100px wide) so I use scroll to manage the view, the problem is the HTML container <TD> where the grid is become very wide ! it suppose not behavior like this even though I give the Grid width to 850px (so my <TD> width) and with the using of the scroll the <TD > must not effected and become very wide like this !.

Second: I have a problem with Custom Aggregate, my grid have 7 coulmn need Aggregate type Custom and I write the

CustomAggregate event procedure but the problem is as I read on this case the Result put in e.Result ! but I have 7 coulmns and each one have its own aggregation and different summation so how can I manage the CustomAggregate with more than one coulmn in my grid ? how I put the Result of each coulmn to its footer ?

Please help and advice me..

Thanks

Ban

Hello Ban,

Straight onto your questions:

#1:
May I ask you to clarify a little bit more your problem, because it is hard for me to understand what the problem exactly is? If the grid has frozen columns and the MasterTableView's HeaderStyle-Width property is not set it is possible <TD> element increase its width while you scroll the window. Is my assumption is right?

#2:
You can distinguish different columns in the OnCustomAggregates event handler using e.Column.UniqueName property. Please review the following code snippet:

    
                protected void RadGrid1_CustomAggregate(object sender, GridCustomAggregateEventArgs e) 
        
                { 
        
                    if (e.Column.UniqueName == "UniqueNameColumn1")  
        
                    { 
        
                        e.Result = "10"; 
        
                    } 
        
                    if (e.Column.UniqueName == "UniqueNameColumn2")  
        
                    { 
        
                        e.Result = "20";         
        
                    } 
        
                }

Hi,

I tried the following codes:

protected void RadGrid1_CustomAggregate(object sender, GridCustomAggregateEventArgs e)

{

if (e.Column.UniqueName == "TinyIntValue")

{

e.Result = "10";

}

if (e.Column.UniqueName == "TinyIntValue2")

{

e.Result = "20";

}

However, the GridCustomAggregateEventArgs object, e, only has Item and Result properties. It doesn't have Column property. Do you know the problem?

Thanks,
