Solution 1

you need a onclick attribute and one hidden field
taken one hidden field

ASP.NET

<asp:hiddenfield id="setup_id" runat="server" value="" xmlns:asp="#unknown" />

and take one checkbox

XML

<asp:checkbox id="chk_centrelink_pensions" runat="server" onclick="getchecked(this);" xmlns:asp="#unknown" />

now in javascript

JavaScript

function getchecked(aa)
{
   $('setup_id').value=aa.id;
}

so now in hiddenfield checked checkbox value will be stored and you can use it .....

Hi...
See this one for all check box checked.
In Script:

XML

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
    <script type="text/javascript">
        $(document).ready(function () {
            $('[id*=chkHeader]').click(function () {
                $("[id*='chkChild']").attr('checked', this.checked);
            });
        });
               </script>

In Body:

XML

<asp:GridView ID="gvUserInfo" runat="server" Width="561px" AutoGenerateColumns="False">
        <HeaderStyle BackColor="#df5015" Font-Bold="true" ForeColor="White" />
        <Columns>
        <asp:TemplateField><HeaderTemplate>
        <asp:CheckBox ID="chkHeader" runat="server" />
        </HeaderTemplate>
        <ItemTemplate>
        <asp:CheckBox ID="chkChild"  runat="server"/>
        </ItemTemplate>
        </asp:TemplateField>

        <asp:TemplateField HeaderText="Id">
                <ItemTemplate>
                <asp:Label ID="lblId" runat="server" Text='<%# Eval("Id") %>'/>
                </ItemTemplate>
                </asp:TemplateField>

In Button.cs:

C#

foreach (GridViewRow gvrow in gvUserInfo.Rows)
            {
                //Finiding checkbox control in gridview for particular row
                CheckBox chkdelete = (CheckBox)gvrow.FindControl("chkChild");

                //Condition to check checkbox selected or not
                if (chkdelete.Checked)
                {
                    string UserName = ((Label)gvUserInfo.Rows[gvrow.RowIndex].FindControl("lblUserName")).Text;
 }
            }
            Label1.Text = UserName;
        }

Like that, find checked values in gridview.
Thank u.
