I have the following Template column in my grid and am having problems setting the value for the edit template's numeric text box. When I click on edit I get the following error "Specified cast is not valid." If I hard code the value or use a standard text box this doesn't happen. Any thoughts?

Thanks,
Bill

Hi wdudek,

Try setting the DbValue property for the RadNumericTextBox as shown below.

ASPX:

    
              <EditItemTemplate> 
        
                <rad:RadNumericTextBox 
        
                 width="60px" 
        
                   id="tbMinValue" 
        
                   runat="server" 
        
                                            DbValue='<%# (double)DataBinder.Eval(Container.DataItem, "MinimumValue") %>'  
        
               Type="Number"></rad:RadNumericTextBox> 
        
             </EditItemTemplate>

Thanks
Shinu.
