header-text in addition to the check box in the GridViewSelectColumn header column

[Gopinath]

Hi 

I want show a header-text in addition to the check box in the GridViewSelectColumn header column of grid view.

When i try to set the header value , i am just getting only the header text

Below is my code sample:

<telerik:GridViewSelectColumn HeaderTextAlignment="Center" MinWidth="90"  Header="SelectAll" >
</telerik:GridViewSelectColumn>

Even i am trying to make the all the checkbox's to center align, but no luck.

Can anyone suggest the approach please.
