Hi,

I'm using VS2008 and Telerik 2011.3.1220.35 and with one of my RadGridView I have a problem :(

The second column of my grid view is a GridViewToggleRowDetailsColumn and when I click on the plus sign, my application fall in an infinite loop and I receive the following message:

Here is my XAML RadGridView definition:

<telerik:RadGridView Height="Auto" Width="Auto" x:Name="RadGridViewBilling" RowLoaded="RadGridView_RowLoaded" Margin="5 0 5 5" Visibility="Visible"  RowDetailsVisibilityMode="Collapsed"

Hello Oliver,

I have tried to get the same exception as the one you described, but without any success. Is there anything more specific that you do in your application ? How do you handle RowLoaded event ? Are there any relevant events that you subscribe to during which you execute a particular logic ? 
Generally, any relevant information and code-snippet would be helpful.

Hi,

as far as I remembered, with an older version of Telerik, this issue was not present.

Here is all my UserControl, I putted all the logic in comment into the RowLoaded event:

}

And here is the code I implement in my main application to use my UserControl:

                BillingGrid billingGrid = new BillingGrid(mDataSource, btn.Text, btn.Text == dict["BillIssuedToReBillAndConc"].ToString());
                billingGrid.GridSelectionChanged += new EventHandler<Telerik.Windows.Controls.SelectionChangeEventArgs>(BillingGridSelectionChanged);
                billingGrid.RadGridViewBilling.ItemsSource = Bills;
                (radTabControlDepartments.Items[radTabControlDepartments.SelectedIndex] as RadTabItem).Content = billingGrid;

        private void BillingGridSelectionChanged(object sender, SelectionChangeEventArgs e)
        {
            displayMessageInPanel(MessagePanel.Second, "Items sélectionnés: " + (sender as RadGridView).SelectedItems.Count.ToString());
        }

        private void displayMessageInPanel(MessagePanel pPanel, string pMessage)
        {
            switch (pPanel)
            {
                case MessagePanel.First:
                                          statusBarItem1.Content = pMessage;
                                          break;
                case MessagePanel.Second:
                                          statusBarItem2.Content = pMessage;
                                          break;
                case MessagePanel.Third:
                                          statusBarItem3.Content = pMessage;
                                          break;
            }

            radRibbonBar.Title = pMessage;
        }

Hello Oliver,

Could you take a look at the sample attached and let me know whether you can get the same behavior and exception on it ? Am I missing something ? Are there any additional steps that I need to follow in order to get the expection ?  


Kind regards,
