How to select all checkboxes present inside a gridview by selecting another checkbox using JQuery..

Checkboxes placed inside gridview:

<asp:TemplateField>

        <HeaderTemplate>

                <asp:CheckBox id="chkSelectAll" runat="server" />

        </HeaderTemplate>

        <ItemTemplate>

                <asp:CheckBox ID="chkSelect" runat="server" />

        </ItemTemplate>

</asp:TemplateField>

The JQuery method for selecting all checkboxes :

<script type="text/javascript">

        function SelectAllCheckboxes(chk) {

            $('#<%=GrdRequestList.ClientID %>').find("input:checkbox").each(function () {

                if (this != chk) {

                    this.checked = chk.checked;

                }

            });

        }

    </script>

Then change your checkboxes as following :

<asp:TemplateField>

    <HeaderTemplate>

        <asp:CheckBox id="chkSelectAll" runat="server" onclick="javascript:SelectAllCheckboxes(this);" />

    </HeaderTemplate>

    <ItemTemplate>

        <asp:CheckBox ID="chkSelect" runat="server" />

    </ItemTemplate

</asp:TemplateField>
