Hi,

I use the XamPivotGrid and XamPivotDataSelector in an WPF Browser Application.

When I drag and drop a field, the XamPivotGrid(or XamPivotDataSelector ) bacome black.

Please help me.

Here is my code:

[xaml]

<Page x:Class="Page1"
      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

      Title="Page1" xmlns:ig="http://schemas.infragistics.com/xaml">
    <Grid>
        <Grid.ColumnDefinitions>
            <ColumnDefinition />
            <ColumnDefinition Width="Auto" />
        </Grid.ColumnDefinitions>
        <ig:XamPivotGrid Name="XamPivotGrid_Result" AllowCompactLayout="True" />
        <ig:Expander Grid.Column="1">
            <ig:XamPivotDataSelector Name="XamPivotDataSelector_Result" />
        </ig:Expander>
    </Grid>
</Page>
