I have a checkbox named chkSelectAll which placed in header. When I click this then all other check boxes inside my DataGrid is Checked. But I want when anyone of the checkbox inside the grid will be unchecked then this chkSelectAll Checkbox will automatically uncheck.

Please check below code .

All what you need is to have custom event setter for the column.. take a look at below sample. It will work for you.
"CheckboxText">
CodeBehind:
publicvoidOnUnChecked(objectsender,RoutedEventArgse)
{
MessageBox.Show("Uncheckedthecheckbox");
}
Please mark it as an answer if it address the issue.

Hi.
To do your task we can do in both client side as well as server side.
To do in client side please follow these articles,
http://www.aspsnippets.com/Articles/Check-Uncheck-all-CheckBoxes-in-ASPNet-GridView-using-jQuery.aspx
and to do in server side
when you click on checkbox then _RowDataBound is called and in this
if (e.Row.RowType == DataControlRowType.Header)
you need to find that checkbox control and set a value in global or Hidden field and when
if (e.Row.RowType == DataControlRowType.DataRow) this row is called in _RowdataBound then check/uncheck the values for each row.
Thanks.
