I have this Code,

  <asp:UpdatePanel runat="server">
    <ContentTemplate>   
        <asp:GridView ID="gvTestDetails" runat="server" AutoGenerateColumns="false" OnDataBound="gvTestDetails_DataBound" EnableModelValidation="true">    
            <Columns>
                <asp:TemplateField HeaderText="Select">
                    <ItemTemplate>
                        <asp:CheckBox ID="cbSelectRecord" runat="server" AutoPostBack="true"  OnCheckedChanged="cbSelectRecord_CheckedChanged"/>
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>
    </ContentTemplate>
</asp:UpdatePanel>

What I want is,When I check one of the CheckBox in Row of the GridView all other CheckBoxes get un-Checked.

Why dont you just use the Mutually Exclusive CheckBox from the Ajax Controll Toolkit ?

Just add it below your CheckBox:

<ajaxToolkit:MutuallyExclusiveCheckboxExtender runat="server"
    ID="RandomID"
    TargetControlID="cbSelectRecord" 
    Key="AllwaysSameID" />

Note: You need to include a scriptmanager and AjaxControllToolkit in your project then. But this isnt bad because the AjaxControllToolkit offers alot of great stuff.

You can loop all rows in the CheckedChanged event and uncheck all others:

protected void cbSelectRecord_CheckedChanged(object sender, EventArgs e)
{
    CheckBox cb = (CheckBox) sender;
    if(cb.Checked)
    {
        foreach(GridViewRow row in this.gvTestDetails.Rows)
        {
            CheckBox rowRb = (CheckBox) row.FindControl("cbSelectRecord");
            if(rowRb != cb)
              rowCb.Checked = false;
        }
    }
}

use JQuery

 <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js">
</script>
<script type="text/javascript">
function checkRecAll() {
var len = document.forms['form1'].elements.length;
var fields = document.forms['form1'].elements;
var chkStatus = document.all("GridView1_chkselall").checked
for (i = 0; i < len; i++) {
if ((fields[i].name.indexOf('chkrecords') != -1)||     (fields[i].name.indexOf('chkrecords') != -1)) {
if (chkStatus == true) {
if (document.all(fields[i].name).disabled == false) {
document.all(fields[i].name).checked = true;
}
}
else {
document.all(fields[i].name).checked = false;
}
}
}
}
</script>

 <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
        <Columns>
            <asp:TemplateField>
                <HeaderTemplate>
                    <asp:CheckBox name="chkselall" ID="chkselall" runat="server" onclick="javascript:checkRecAll()">
                    </asp:CheckBox>Select All
                </HeaderTemplate>
                <ItemTemplate>
                    <asp:CheckBox ID="chkrecords" runat="server"></asp:CheckBox>
                </ItemTemplate>
            </asp:TemplateField>
             <asp:BoundField DataField="Name" HeaderText="Name" />
            <asp:BoundField DataField="Age" HeaderText="Age" />
        </Columns>
    </asp:GridView>
