           var count = document.getElementById("<%=hfCount1.ClientID %>").value;

           for (var i = 0; i < chk.length; i++) {
               if (chk[i].checked && chk[i].id.indexOf("chkHeader") == -1) {
                   count++;
               }
           }
           if (count == 0) {
               document.getElementById("<%= lbl.ClientID %>").innerHTML = "No record selected to edit.";
               return false;
           }
           else {
               if (count > 1) {
                   document.getElementById("<%= lbl.ClientID %>").innerHTML = "Multiple edit is not allowed.";
                   return false;
               }
           }
       }

while chking the input i am getting all the checkbox in three columns.
its creating problem for other operation on the status column.

Any one can tell me that how i can get the check box of that particular column

ie. if i am having 10 row in my gridview then the

var chk = gv.getElementsByTagName("input"); must have value 10 not 30 as i am getting.

Suppose the "select" checkboxes are at column 1(index 0). Following is the sample code. Just modify it and give it a try.

JavaScript

function ConfirmEdit() 
{
vargrid = document.getElementById("<%= gvItemCategory.ClientID %>"); 
var cellToCheck;
var count = 0;
if (grid.rows.length > 0)
{
for (i=1; i<grid.rows.length;>{
cellToCheck = grid.rows[i].cells[0];
for (j=0; j<celltocheck.childnodes.length;>{          
if (cellToCheck.childNodes[j].type =="checkbox")
{
if(cellToCheck.childNodes[j].checked == true)
count++;
}
}
}       
}
}

The line in bold is used for checkboxes in column "0".
