The above code will slow down the browser and the browser can hang when Rows in Grid will be 10000 or above. Please view the below suggestion:

CS Code

C#
protected void grvGroups_RowDataBound(object sender, GridViewRowEventArgs e)
{
 if (e.Row.RowType == DataControlRowType.DataRow)
  {
    e.Row.Attributes.Add("onclick", "setGridValue('" + e.Row.ClientID + "')");
  }
}

HTML Code

CSS
.sel
{
     color: #303030;
     font-size:3em;
     font-weight:bold;
     cursor:default;
}
.desel
{
     color: #909090;
     font-size:2em;
     font-weight:normal;
     cursor:pointer;
}

 

JavaScript
var oldro;
function setGridValue(ro)
{
 var rs=document.getElementById(ro);
 if(oldro!=null)
 {
  if(rs.className=="sel")
   return;
  oldro.className="desel";
 }
 rs.className="sel";
 oldro=rs;
}

And forget then loop.

you r using
var _row = document.getElementById(ro)
and not
var rs = document.getElementById(ro)
so rs is null
you should use rs in place of _row
or use _row in place of rs
