Check and Uncheck GridView Check Box

This Snippet is used to Check and Uncheck the Check boxes of the grid view.Some times we find a requirement to check the Check box which is in the header and to check the each row check box.

To use this function common to Asp.Net Programmers who uses this requirement.
Steps to Change in this Function:

1. Change the GridView ID.
2. Change the Header Check box ID.
3. Change the all rows having Check box ID also.

Function CheckUncheckAllCheckBoxAsNeeded()
{
      var totalCheckboxes = $("#gv1 input[id*='chckAll']:checkbox").size();
      var checkedCheckboxes = $("#gv1 input[id*='chckAll']:checkbox:checked").size();
      if (totalCheckboxes == checkedCheckboxes)
      {
            $("#gv1 input[id*='chckbxOneByOne']:checkbox").attr('checked', true);
      }
      else
      {
            $("#gv1 input[id*='chckbxOneByOne']:checkbox").attr('checked', false);
      }

}
