This Concept is used to, just click on header checkbox then the all checkbox are checked with out postback operation by using javascript. For example in yahoo mail u just click the header checkbox all grid checkbox will be selected

// This is the javascript code. Just copy and paste the code within the script tag

function CheckAllDataGridCheckBoxes(aspCheckBoxID, checkVal)

{

re = new RegExp(':' + aspCheckBoxID + '$')

for(i = 0; i < Form1.elements.length; i++)

{

elm = document.forms[0].elements[i] if (elm.type == 'checkbox')

{

if (re.test(elm.name)) elm.checked = checkVal

}

// This is the sample design structure of the datagrid, in only display the checkbox and name

<imagebutton id="btnDownload" commandname="cmdDownload" runat="server" imageurl="/jobants/images/download.gif"><asp:datagrid id="dgReciveApp" runat="server" AutoGenerateColumns="False" Width="100%" PageSize="15"
