Hi,

I have a RadGrid setup which displays info from a table. In one specific column I need to get additional information using a static function and display it next to the cell value. I tried using the <%# %> but it just complained that it doesn't allow it. Is there a way to call a static function in the namespace, add the databound parameter as an input parameter and get the result? Here is the code I tried:

    
            <telerik:GridBoundColumn DataField="uwr_id" DataType="System.Int64"  
        
                        HeaderText="Request ID"  
        
                        ReadOnly="True"  
        
                        SortExpression="uwr_id"  
        
                        UniqueName="uwr_id" 
        
                        DataFormatString="<%# Base.DBManager.getRelatedTasks(DataBinder.Eval(Container.DataItem,"uwr_id")) %>" > 
        
                    </telerik:GridBoundColumn>

The DBManager getRelated tasks is as follows:

    
            public static string getRelatedTasks(object obj) 
        
                    { 
        
                        long uwr_id = (long)obj; 
        
                        string res = "SIMPLE RES "; //no processing, just for testing 
        
                        return res; 
        
                    }

This is the error I get:

    
            Server Error in '/' Application.

Any suggestions?
