Hi,
  I am having Ultragrid html markup like following in which i am having two template columns.
on each template column header there is checkbox to enable SELECT ALL option.
 I am calling a javascipt function shown below on onclick event of header checkboxes.
the select all option is not working as in the if condition it is not finding frm.elements[i].name.lastIndexOf("CheckBox2") for all 4 function

please suggest some solution so that the Select all function on both column will work.

Thanks.

 
function Delete()
    {
        var frm = document.forms[0];
        var flag=false;
        for (i=0;i<frm.elements.length;i++)
        {
            //alert("Delete _ _ _ "+frm.elements[i].name);
           if(frm.elements[i].type == "checkbox"  && frm.elements[i].name.lastIndexOf("CheckBox2")!= -1)
           {
             //alert("Sucess___"+frm.elements[i].name);
             if(frm.elements[i].checked)
              {
                 flag = true;
              }
           }
        }
        if (flag==false)
        {
           alert('Please select at least one item to delete!');
           return false;
        }
       
        return confirm('Are you sure to delete selected Roles?');
    }

 function SelectAll(flag)
    {
       alert(error);
        var frm = document.forms[0];
        for (i=0;i<frm.elements.length;i++)
        {
          //  alert("DeleteSelectAll _ _ _ "+frm.elements[i].name);
           if (frm.elements[i].type == "checkbox" && frm.elements[i].name.lastIndexOf("CheckBox2")!= -1)
           {
               frm.elements[i].checked = flag; // document.getElementById(id).checked;ChkEnable              
           }
        }
    } 
 
  function EnableDisable()
    {
        var frm = document.forms[0];
        var flag=false;
        for (i=0;i<frm.elements.length;i++)
        {
          if(frm.elements[i].type == "checkbox" && frm.elements[i].name.lastIndexOf("CheckBox1")!= -1)
           {
             if(frm.elements[i].checked)
              {
                 flag = true;
              }
           }
        }
        if (flag==false)
        {
           alert('Please select at least one item to Enable/Disable!');
           return false;
        }
       return confirm('Are you sure to Enable/Disable?');
    }

 function SelectAllEnableDisable(flag)
    {
      alert(error);
        var frm = document.forms[0];
        for (i=0;i<frm.elements.length;i++)
        {           
           if (frm.elements[i].type == "checkbox" && frm.elements[i].name.lastIndexOf("CheckBox1")!= -1)
           {
                alert('found one record, name is..'+frm.elements[i].name);
                frm.elements[i].checked = flag; // document.getElementById(id).checked;
           }
        }
