In my  gridview  I have a checkbox  column , so, I have a check box as a header for that column.
The interaction part I want to use javascript. Does anyone have a good sample code for me ?
Thank you,

This link is also very nice, and its for gridview control checkboxs.

http://weblog.vb-tech.com/nick/archive/2005/09/26/1300.aspx

function doAllChecks()
{
 re = new RegExp('_chkMove')


 if(document.Form1['Datagrid1_ctl1_chkAction'].checked == true)
 {
   for (var iCount=0;iCount
  {
   elm = document.forms[0].elements[iCount]

    if (elm.type == 'checkbox') {

     if (re.test(elm.id)) {
      elm.checked = true;
     }
    }
   
  }
 }
 else
 {
 
 
  for (var iCount=0;iCount
  {
   elm = document.forms[0].elements[iCount]

    if (elm.type == 'checkbox') {

     if (re.test(elm.id)) {
      elm.checked = false;
     }
    }
   
  }
 }
}

Do you have a working  sample of this ?.
What if one of the checkboxes get uncheck in the gridview tahn we have to uncheck the checkbox in the header, How to do that?.

And in the code  " if(document.Form1['Datagrid1_ctl1_chkAction'].checked == true)
"
is Datagrid1_ctl_chkAction" the id of the header checkbox ?
and about the regular expression  re = new RegExp('_chkMove')
waht happens here ?. what is  "_chkMove"  the id of the checkbox in the columns ?

Please attach a sample working code if you haveone for the GridView
Thank you
