GridLines cannot be displayed or hidden when changing the property GridLinesVisibility

[Xiaojun]

It's very strange that there are some rows cannot display grid lines when I change the RadGridView's property GridLinesVisibility's value from None to Both. And also when I change the value from Both to None, there are some rows cannot hide the grid lines.
I use silverlight 4 and the telerik version is 2011.1.0419.1040

Is this a bug of RadGridView? How can I fix it?

Hi Xiaojun,

 
I have tried to replicate the behavior you described, but I was not able to. May you please take a look at the attached project and let me know how it differs from yours? Considering the pictures attached I believe that this problem could be related to some custom settings. Do you have any styles targeted either at GridViewCell or at GridViewRow which may affect the grid lines? I am attaching you a runnable application which I used for testing.  Feel free to modify it and send it back to us as an attachment in a new support ticket. 

Best wishes,
