Asp Dot Net Gridview with ChechBox

Hi in this tutorial explains how to get selected rows from gridview using asp dot net Checkbox control.Open your MsSql server and create a database with name "User" and then create a table "userRegistration".

Html Tag Code:

 <asp:GridView ID="grdViewDemo" AutoGenerateColumns="false" runat="server">

            <Columns>

                <asp:BoundField DataField="id" HeaderText="Id" />

                <asp:BoundField DataField="name" HeaderText="Name" />

                <asp:BoundField DataField="Address" HeaderText="Address" />

                <asp:BoundField DataField="City" HeaderText="City" />

                <asp:BoundField DataField="State" HeaderText="State" />

                <asp:BoundField DataField="Country" HeaderText="Country" />

                <asp:TemplateField HeaderText="Action">

                    <ItemTemplate>

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

                    </ItemTemplate>

                </asp:TemplateField>                

            </Columns>

        </asp:GridView>                

        <br />

        <asp:Button ID="btnFetch" runat="server" CssClass="btn btn-warning" OnClick="btnFetch_Click" Text="Fetch Row" />

        <br />

        <asp:GridView ID="grdVide" AutoGenerateColumns="false" runat="server">

            <Columns>

                    <asp:BoundField DataField ="id" HeaderText="id" />

                    <asp:BoundField DataField="name" HeaderText="Name" />

                    <asp:BoundField DataField="Address" HeaderText="Address" />

            </Columns>

        </asp:GridView>

BindData To GridView:

protected void Page_Load(object sender, EventArgs e)
        {
            if (!this.IsPostBack)
            {
                this.BindData();
            }
        }

        private string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
        private void BindData()
        {
            SqlConnection conn = new SqlConnection(constr);
            SqlCommand cmd = new SqlCommand();
            string sqlQuery = "Select *FROM tblUserRegistration";
            cmd.Connection = conn;
            cmd.CommandText = sqlQuery;
            cmd.CommandType = System.Data.CommandType.Text;
            DataTable dt = new DataTable();
            SqlDataAdapter sda = new SqlDataAdapter(cmd);
            sda.Fill(dt);
            grdViewDemo.DataSource = dt;
            grdViewDemo.DataBind();

        }

Code to Get Data From Selected Check box and Insert it into another GridView:

protected void btnFetch_Click(object sender, EventArgs e)
        {
            DataTable dt = new DataTable();
            dt.Columns.Add("Id");
            dt.Columns.Add("Name");
            dt.Columns.Add("Address");
            foreach (GridViewRow grdRow in grdViewDemo.Rows)
            {
                CheckBox chkRow = (grdRow.Cells[6].FindControl("checkBox") as CheckBox);
                if (chkRow.Checked)
                {
                    string id = grdRow.Cells[0].Text;
                    string name = grdRow.Cells[1].Text;
                    string Address = grdRow.Cells[2].Text;
                    dt.Rows.Add(id, name, Address);
                }
            }

            grdVide.DataSource = dt;
            grdVide.DataBind();

        }
