Hi Jenny,

GridClientSelectColumn has already built-in header checkbox provided out-of-the-box:
https://demos.telerik.com/aspnet-ajax/grid/examples/functionality/selecting/row-selection/defaultcs.aspx

If you decide on using templates, you can use something similar to the attached web site sample.

As for GridCheckBoxColumn, you can create a new asp:CheckBox in the code-behind and add it to the corresponding cell of the GridHeaderItem.

I hope this will prove helpful.

Eyup

Hello Jennifer,

It seems that this account has no active license attached to it for Telerik UI AJAX toolset. You can contact our sales team to handle this and once this is done, we can continue with the technical question.
