How To Implement Select All/Unselect All CheckBoxes in GridView Rows
In my last posts, I explained How To Add CheckBox to GridView and How To Get Selected Multiple Rows From GridView. In this post, I will explain how can you select/unselect all rows of a GridView by selecting a CheckBox in client side.

The only difference I will make here is add a CheckBox in the header of the Checkbox column using the HeaderTemplate clicking on which will toggle the state of checkboxes in each row of the GridView. To toggle the state of check boxes, we will use a little bit of jQuery. Below is the code for the same.
