I have used RadGridViews(Telerik.Windows.Controls.GridView) in WPF that has some column. The header of column is a CheckBox. Some times header CheckBox content binding is works fine, but when i changed to another form and return back to the same form CheckBox content binding doesn't work ie, its not showing the CheckBox contant.

the code is below
   <telerikGrid:RadGridView >
 <telerikGrid:RadGridView.Columns>                                
                            <telerikGrid:GridViewDataColumn  DataMemberBinding="{Binding Name}" >
                                <telerikGrid:GridViewBoundColumnBase.Header  >
                                    <CheckBox IsChecked="False"  Content="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type telerikGrid:RadGridView}}, Path=DataContext.HeaderName}" />
                                </telerikGrid:GridViewBoundColumnBase.Header>
                            </telerikGrid:GridViewDataColumn>
</telerikGrid:RadGridView >

its shows some time like this

any solution pls send me, very urgent..
thanks

VirtualizingStackPanel.IsVirtualizing

="True"

ScrollMode="RealTime"

VirtualizingStackPanel.VirtualizationMode="Recycling"

ScrollViewer.IsDeferredScrollingEnabled="True"

and

<telerik:GridViewDataColumn Header="" Width="35" DataMemberBinding="{Binding IsSelected, Mode=TwoWay}">

<telerik:GridViewDataColumn.CellTemplate>

<DataTemplate>

<RadioButton Click="radEditGroup_Click" HorizontalAlignment="Center" Checked="radEditGroup_Checked" IsChecked="{Binding Path=IsSelected, Mode=TwoWay}" x:Name="radEditGroup" GroupName="Groups" />

</DataTemplate>

</telerik:GridViewDataColumn.CellTemplate>

</telerik:GridViewDataColumn>

In .cs file for Checked ="radEditGroup_Checked" i looped through groups and deselected the radio buttons and displayed last checked button value.

private

void radEditGroup_Checked(object sender, RoutedEventArgs e)

{

try

{

ClearMessage();

if ((sender as RadioButton) != null &&

((sender

as RadioButton).DataContext as Groups) != null)

{

var lobjSelectedGroups = from lobGroup in _Groups

where lobGroup.IsSelected == true

select lobGroup;

if (lobjSelectedGroups != null)

{

foreach (Groups lobGroup in lobjSelectedGroups)

{

lobGroup.IsSelected =

false;

}

}

this._intGroupID = ((sender as RadioButton).DataContext as Groups).FUNCTION_GRP_ID;

this._intFunctionId = ((sender as RadioButton).DataContext as Groups).Function_Id;

(sender

as RadioButton).Checked -= radEditGroup_Checked;

(sender

as RadioButton).IsChecked = true;

(sender

as RadioButton).Checked += radEditGroup_Checked;

}

}

catch (Exception objEx)

{

ErrorHandling.CatchAllExceptions(objEx);

}

}
