CanUserAddRows causes Error

Sep 12, 2008 at 7:22 AM
I am using Expression Blend together with the DataGrid. Now when I select "CanUserAddRows" I get an exclamation mark with the error message: "NewItemPlaceholderPosition is not allowed for this view".
I am very new to DataGird and have no idea what this message means. Can anybody help me, please?

I found out that if i edit the xaml (instead of using the checkbox in the designer) and set it to CanUserAddRows="True" this will work, but the checkbox in the designer will always be unchecked ( I am using Blend 2.5 June 2008 Preview). But if I klick on the little white square beside "CanUserAddRows" in the designer, klick "Reset" and then check the checkbox, I will always get the above error.

The error that you see when trying to reset is a bug and will be addressed in the v1 release.
