Prevent updating binding properties on column size change.

[Tegu]

Hello,

There is a RadDataGrid with couple of DataGridTemplateColumns. One of the column contains a MediaPlayerElement as a video preview.

The realized problem is when I am changing any column's size, the grid and all of the contained element's bindings are automatically read again. It causes a couple of error (and ugly behavior) on the MediaPlayerElement, the rest of the columns are working fine.

 

The Grid:

        <telerikGrid:RadDataGrid x:Name="GridVideoFiles" Grid.Row="1" UserEditMode="External" AutoGenerateColumns="false" UserFilterMode="Disabled" UserGroupMode="Disabled"
                                 ColumnResizeHandleDisplayMode="Always"
                                 DragOver="UIElement_OnDragOver" AllowDrop="True"
                                 Drop="UIElement_OnDrop"
                                 ItemsSource="{Binding VisionFiles}">

The given column:

                <telerikGrid:DataGridTemplateColumn Header="Video Player" SizeMode="Fixed" Width="300" CanUserResize="False">
                    <telerikGrid:DataGridTemplateColumn.CellContentTemplate>
                        <DataTemplate>
                            <Grid Width="300">
                                <MediaPlayerElement Width="300" Source="{Binding Media, Mode=OneTime}" AreTransportControlsEnabled="True">
                                    <MediaPlayerElement.TransportControls>
                                        <MediaTransportControls IsCompact="True"/>
                                    </MediaPlayerElement.TransportControls>
                                </MediaPlayerElement>
                            </Grid>
                        </DataTemplate>
                    </telerikGrid:DataGridTemplateColumn.CellContentTemplate>
                </telerikGrid:DataGridTemplateColumn>

 

Can you tell me any solution to prevent the binded Media property updating automatically?

Hello,

I have just test the described case in a basic setup with RadDataGrid, however, the bindings are not fired during column resizing.  I have attached my test project, could you download it and give it a try? Can you modify it with your code, so that the issue could be replicated and send it back to us?

Thanks in advance
