Hello Naresh,

Try the following to achieve your requirement.
C#:

protected void grdEmail_ItemCreated(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridHeaderItem)
        {
            GridHeaderItem Hitem = (GridHeaderItem)e.Item;
            CheckBox chk = (CheckBox)Hitem["ClientColumnUniqueName"].Controls[0];
            chk.Attributes.Add("onclick", "change();");
        }
        if (e.Item is GridDataItem)
        {
         GridDataItem item = (GridDataItem)e.Item;
          if(item["FirstName"].Text=="king")//based on some condition
          {
            CheckBox chk = (CheckBox)item["ClientColumnUniqueName"].Controls[0];
            chk.Enabled = false;
          }
        }
    }

Javascript:

function change()
 {
   var masterTable = $find("<%= grdEmail.ClientID %>").get_masterTableView();
   for (var index = 0; index < masterTable.get_dataItems().length; index++)
     {
            var row = masterTable.get_dataItems()[index]; ;
            var cell = masterTable.getCellByColumnUniqueName(row, "ClientColumnUniqueName");
            var chk = cell.getElementsByTagName("input")[0];
            if (chk.disabled)
            {
                chk.checked = false;
            }
            else
            {
                chk.checked = true;
            }
        }
 }

Hope it helps.

Thanks,
Princy.
