Visual Studio not recognizing the "Background" property on VirtualizingCellsControl

[john]

This is probably something stupid.  I'm just trying to set an alternating row color for my sfdatagrid, following examples.  Using v31.2.12.

        <Style x:Key="alternatingRowStyle" TargetType="sf:VirtualizingCellsControl">
            <Setter Property="Background" Value="Blue"/>
        </Style>

Errors:

• Error XLS0431 Invalid value for property 'Property': 'Background' MyProjectName C:\Users\Me\source\repos\MyProject\MyProject\UserControls\MyUserControl.xaml 26
• Error (active) MC4005 Cannot find the Style Property 'Background' on the type 'Syncfusion.Windows.Controls.Cells.VirtualizingCellsControl'. Line 26 Position 21. MyProjectName C:\Users\Me\source\repos\MyProject\MyProject\UserControls\MyUserControl.xaml 26

Even stranger is both intellisense and 'go to definition' finds the property just fine.  Only the compiler fails.

Hi john,

We have reviewed your provided information and suspect that you have used both Syncfusion.SfGrid.WPF and Syncfusion.GridCommon.WPF DLLs. These DLLs share a common namespace http://schemas.syncfusion.com/wpf. Additionally, the VirtualizingCellsControl exists in both DLLs with the same name, which can lead to an ambiguous type reference exception if you reference http://schemas.syncfusion.com/wpf in your project.

To resolve this, you can explicitly declare the namespace for VirtualizingCellsControl by specifying the assembly, as shown below:

Code snippet to resolve ambiguous error:

<Window x:Class="SfDataGrid_Demo4_8.MainWindow"

                     xmlns:syncfusion="clr-namespace:Synfusion.UI.Xaml.Grid;assembly=Syncfusion.SfGrid.WPF">

 
 <Style TargetType="syncfusion:VirtualizingCellsControl">

               <Setter Property="Background" Value="Blue"/>

 </Style>
