Hello all,

I am building a GridView with 20 columns showing some 150 rows. Since this is quite a wide table, and I want the user to be able to edit the table easily, I decided to use a RowDetailsTemplate that will actually be a form with all the edditable data from the selected row. I tried doing this like in the "Row Details" sample that is installed with the 2009 Q2 release (i.e. with the details view in a separate user control). The problem is that when I do that, the grid trows me an OutOfMemoryException. If on the other hand, I put the template directly in the grid control's resources, it works just fine.

Here are a few lines of code to show what I'm doing:

In the Grid's resources:

    
            <Grid.Resources>   
        
                 <DataTemplate x:Key="PropertySetDetails">   
        
                     <local:PropertySetDetails />   
        
                 </DataTemplate>   
        
            </Grid.Resources>

In the GridView's definition:

    
            <telerikGridView:RadGridView x:Name="propertySetGridView" Grid.Row="2"      
        
                                         CanUserInsertRows="true" AutoGenerateColumns="False"      
        
                                         RowDetailsTemplate="{StaticResource PropertySetDetails}"      
        
                                         RowDetailsVisibilityMode="VisibleWhenSelected">

In the user control file for the details view (in the same silverlight project) I have a grid with some controls:

    
            <UserControl x:Class="MyProject.PropertySetDetails"   
        
            xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"   
        
            xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">   
        
                <Grid x:Name="DetailsLayoutRoot">   
        
                    <Grid>   
        
                        <Grid.ColumnDefinitions>   
        
                            ...  
        
                        </Grid.ColumnDefinitions>   
        
                        <Grid.RowDefinitions>   
        
                            ...          
        
                        </Grid.RowDefinitions>   
        
                        ...          
        
                        <TextBlock Text="Name" Grid.Column="1" Grid.Row="1"/>   
        
                        <TextBox x:Name="nameTextBox" Grid.Column="2" Grid.Row="1" Text="{Binding Name}" /> 
        
                    </Grid>   
        
                </Grid>   
        
            </UserControl>

Now this gives me the exception. Like I said, if I take out the grid markup from the separate file and put it the GridView's file (in the resources section), it works!
What am I doing wrong? I am new to Silverlight (and C#) so please take that into consideration in your reply.

Thanks in advance,
AM.
