aspxgridview,checkbox and check all

tomorrow_ft

hi, I am using an aspxgridview and two checkboxes(for header and dataitem).When I check header checkbox I want to check all checkbox.I am also using java script code.essentially, I can do this, but I must check header checkbox twice times.I didnt understand why it is happening.ı am writing this code checkbox_checked event and header checkbox's autopostpak is true. When I used normal gridview I didnt have any problem I could do this without problem.,

    var IsChecked = id.checked;
    var Chk = id;
   // Parent = document.getElementById('GrdPerliste');
    Parent = document.getElementById('<% = GrdPerliste.ClientID%>');

    var items = Parent.getElementsByTagName('input');
    for (i = 0; i < items.length; i++) {
        var deneme = items\[i\].type;
        if (items\[i\].id != Chk && items\[i\].type == "checkbox") {
            if (items\[i\].checked != IsChecked)
            { items\[i\].click(); }
        }
    }

}
    </script>

protected void Checksec_CheckedChanged2(object sender, EventArgs e) { CheckBox chk = (CheckBox)sender; GridViewHeaderTemplateContainer bulundugucontainer = (GridViewHeaderTemplateContainer)chk.NamingContainer; ((CheckBox)bulundugucontainer.FindControl("Checksec")).Attributes.Add("onclick", "javascript:SelectAll('" + ((CheckBox)bulundugucontainer.FindControl("Checksec")).ClientID + "')"); }

try this javascript function

//cntrl- ID of the parent Check box
//grd - Cliend ID of the HTML Table or GridView in which all the check boxes
// are present
// indCat - 1 or 2 indicates call from parent or child

function SelectAll(cntrl,grd,indCat)
{
var grdComp = document.getElementById(grd);

if(indCat == '1')    
{
    for(i=1;i<=grdComp.getElementsByTagName('input').length-1;i++)
    {
        grdComp.getElementsByTagName('input')\[i\].checked = cntrl.checked;
    }
}
else if(indCat == '2')
{ 
    var chkInd = true;
    for(i=1;i<=grdComp.getElementsByTagName('input').length-1;i++)
    {                 
        if(grdComp.getElementsByTagName('input')\[i\].checked == false)
        {
            chkInd = false;
        }                    
    }
    grdComp.getElementsByTagName('input')\[0\].checked = chkInd;             
}

}

hope this helps
