A first chance exception of type 'System.ArgumentException' occurred in Telerik.Windows.Data.dll

Hi,

I'm having a problem with the grid view control.

During runtime my grid displays the content correctly, however when you scroll the grid up and down it throws exceptions in the VS output window.  They seem to slow the entire application down.

A first chance exception of type 'System.ArgumentException' occurred in Telerik.Windows.Data.dll

Enclosed is the XAML

<

 

UserControl x:Class="GridTeams"

 

 

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

 

 

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

 

 

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation" >

 

 

 

<UserControl.Resources>

 

 

 

 

</UserControl.Resources>

 

 

 

<Grid>

 

 

 

<telerik:RadGridView ItemsSource="{Binding Source={StaticResource DataTeams}}"

 

 

Margin="10">

 

 

 

<telerik:RadGridView.Columns>

 

 

 

 

<telerik:GridViewDataColumn DataMemberBinding="{Binding XPath=TN}"/>

 

 

 

 

 

</telerik:RadGridView.Columns>

 

 

 

</telerik:RadGridView>

 

 

 

</Grid>

 

</

 

UserControl>

 

I'm using RadControls_for_WPF_2009_3_1208_TRIAL.msi

When I run another demo with the same content it doesnt seem to cause the same effect.   Therefore I am confused as to where the problem is coming from.  Any help would be appreciated.

Kind regards
Neil

Hi,

I have tried the application and it's not showing any errors now when running from Visual Studio.

I have just retried my old app and to check my sanity and it is still doing it?

Kind regards
Neil

Hi Vlad,

Have you managed to find any reason why the exceptions were occurring in my app?

Kind regards

Hello Neil,

Unfortunately I'm not sure why you get these exceptions since I was unable to reproduce them locally - can you verify the grid version once again in your project?

Best wishes,

I have a similar problem with a WPF gridview.  To ensure they appear in the output window make sure System.ArgumentException is user-handled and/or thrown in Visual Studio (Debug-->Exceptions-->CLR Exceptions-->System).

Hello Eric,

 These problems were almost a year ago - can you post more info about your grid version?
