Hi,

When user clicks on column header and drags mouse over other column headers,multiple columns should get selected. I am able to achieve column selection on click of column header by Preview mouse down event of header cell control but multiple column selection through click and drag on column headers, I am not able to achieve. Style used for selection of column on column header is:

<Style TargetType="{x:Type igPrim:HeaderCellControl}"     BasedOn="{StaticResource HeaderCellControlStyle}">          

      <EventSetter Event="PreviewMouseDown" Handler="HeaderControl_PreviewMouseDown" />  

</Style>

Please provide a solution to achive column selection through click and drag of column header. Thanks in advance.

Regards,
