Hello I am having a problem with the grid using custom databinding row templates. I am getting random white lines that are getting injected into the grid when sort the grid. This is randomly happening, but does not occur the first time the grid is bound. I am using MVVM with Caliburn.Micro and here is my XAML

<Controls:RadGridView ItemsSource="{Binding Alerts}" CanUserFreezeColumns="False" ScrollMode="Deferred" IsReadOnly="True" x:Name="Alerts" GridLinesVisibility="None" AutoGenerateColumns="False" CanUserReorderColumns="False" CanUserSortColumns="True" MinHeight="400" RowStyle="{StaticResource rowStyle}" Height="535" SelectionMode="Multiple">

<Controls:RadGridView.Columns>

<Controls:GridViewDataColumn Header="Alert Date" DataMemberBinding="{Binding AlertDate}" IsFilterable="False" Width="150" />

<Controls:GridViewDataColumn Header="Alert Type" DataMemberBinding="{Binding AlertType}" IsFilterable="False" Width="100" />

<Controls:GridViewDataColumn Header="Job Name" DataMemberBinding="{Binding Path=Job.JobName}" IsFilterable="False" Width="100" />

<Controls:GridViewDataColumn Header="Comment" DataMemberBinding="{Binding Comment}" IsFilterable="False" Width="100" />

</Controls:RadGridView.Columns>

</Controls:RadGridView>

and my template for the control

<StackPanel.Resources>

<ControlTemplate x:Key="AlertRowTemplate" TargetType="telerik:GridViewRow">

<Border x:Name="rowsContainer" BorderBrush="#FFA0AFC3">

<UserControl cal:View.Context="{Binding AlertType}" cal:View.Model="{Binding}"></UserControl>

</Border>

</ControlTemplate>

<Style x:Key="rowStyle" TargetType="telerik:GridViewRow">

<Setter Property="Template" Value="{StaticResource AlertRowTemplate}" />

</Style>

</StackPanel.Resources>

Is this a known issue? or is it something that is screwed up in my markup?

Thanks for your help!

Indeed we are using the 2011 Q2 Official Release. On further reveiw of the problem that we are having the grid apears to not be displaying the control that we are binding to. A little more background on the issue

1) We have a series of controls that represent the item that we are bindng to in different states.
2) The Controls are being being bound to the Grid just fine on the initial databinding of the grid.
3) When we scroll or sort the grid be start to get white spaces where the controls should be, and in the size of the spaces is consistant with what we would expect for the size of the control.

It apears that something within the grid or maybe else where in preventing the Item from being displayed properly.

Thanks again for your help!
