GridView with CheckBox

[Marcelo]

HI,

I have a GridView with a checkbox column. When I would click on the column header checkbox checks all stay true.
Could anyone help me?

Hi Marcelo,

Please take a look at following KB article which could help you implement the desired functionality: Add "Check All" in the header cell for a GridViewCheckBoxColumn

When modifying the value of the selection cell in the code, the checkbox in the header doesn't get updated. How is it possible interact with the cell header at runtime?

I'm using this checkbox column in a multiselect mode RadGridView and when I call SelectAll(), it doesn't get updated. Any idea?

Thanks!
