BindingExpression path error: ContentHorizontalOffset

[Phillip Garrett]

Hi,

I'm getting the following error:

System.Windows.Data Error: BindingExpression path error: 'ContentHorizontalOffset' property not found on 'Type'

I do <telerik:RadGridView ItemsSource="{Binding Collection}" />
Where Collection is an ObservableCollection<Type>.

Something out of my control appears to be trying to locate a ContentHorizontalOffset property in my Type class.

The error doesn't seem to effect (i.e. application still works). Could you help me understand why these messages appear?

Thanks,

Phill

Hi Phillip Garrett,

My assumption is that you have defined a GridViewDataColumn which is bound to a ContentHorizontalOffset property of your class, but such property does not exist. Please check the spelling.

Can you post here more information like the related class definition and gridview declaration?

Thanks

Best wishes,

Hi,

I have discovered that it is the DataLoadMode property on the RadGridView that causes the generation of these error messages.
With DataLoadMode="Asynchronous" the errors appear; with DataLoadMode="Synchronous" the errors magically disappear.
Any thoughts?

Regards,

Phill

we have the same issue here is our grid (it's the only one in which we have it):

Hello guys,

That could be a bug in the asynchronous data load mode. To confirm that and find a solution easily we need to reproduce the problem. Can you please open a support ticket and attach a sample project there?

Thank you

Was this ever fixed? I am having the same problem with these binding errors showing up, although nothing in my code references "ContentHorizontalOffset".

Hi Geoff,

 Please download our latest build - the issue is already fixed!
