Gridview Filter throws an error after changing theme dynamically

[bala]

Hi,

I am using  telerik:StyleManager.Theme property in XAML to bind a theme to gridview dynamically.
 <telerik:RadGridView x:Name="grdTest" VerticalAlignment="Bottom" telerik:StyleManager.Theme="{Binding CurrentTheme, Mode=TwoWay}">
                    <telerik:RadGridView.Columns>
                        <telerik:GridViewColumn Header="test1" />
                        <telerik:GridViewColumn Header="test2" />
                    </telerik:RadGridView.Columns>
                </telerik:RadGridView>
There is a Button on the application to change the theme and when theme is changed, the value of the CurrentTheme property changed. Based on the new value gridview theme also changing properly, but the filter is not working, it throws an error in java script
SCRIPT5022: Unhandled Error in Silverlight Application

To repeat the scenario, follow the below steps:
1)  on page load, click on the gridview filter 
2) now change the theme
3) then click on filter again, it throws an error

When i use style manager to set the theme instead of telerik:StyleManager.Theme, it works fine.

Can any one suggest how to resolve this issue.

Thank you.

Regards,
Bala.
