Fetch Gridview rows value on button click

Fetch Gridview rows value  on button click

Step 1: Design web from .aspx page

     <div>

            <asp:GridView ID="gr" runat="server" AutoGenerateColumns="false" AlternatingRowStyle-BackColor="WhiteSmoke" Width="40%">

                <HeaderStyle BackColor="#3366ff" Font-Bold="true" ForeColor="White" />

                <Columns>

                    <asp:TemplateField HeaderText="Name">

                        <ItemTemplate>

                            <asp:Label ID="lbl_Name" runat="server" Text='<%#Eval("Name") %>'></asp:Label>

                        </ItemTemplate>

                    </asp:TemplateField>

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

                    <asp:TemplateField HeaderText="Phone">

                        <ItemTemplate>

                            <asp:Label ID="lbl_phone" runat="server" Text='<%#Eval("Phone") %>'></asp:Label>

                        </ItemTemplate>

                    </asp:TemplateField>

                </Columns>

            </asp:GridView>

            <br />

            <asp:Button ID="btn_chk" runat="server" Text="Fetch" OnClick="btn_chk_Click" BackColor="YellowGreen" />

        </div>

Step 2 : Logic on .Cs page

protected void Page_Load(object sender, EventArgs e)

    {

        if (!IsPostBack)

        {

            //Bind Gridview

            bind_gr();

        }

    }

    public void bind_gr()

    {

        DataTable dt = new DataTable();

        dt.Columns.Add("Name");

        dt.Columns.Add("City");

        dt.Columns.Add("Phone");

        dt.Rows.Add("Kandy", "Delhi", "8802***2564");

        dt.Rows.Add("Sam", "Hr", "545502*2544");

        dt.Rows.Add("Izhar", "Up", "95802*2452");

        dt.Rows.Add("Vineet", "Delhi", "88022564***");

    

        gr.DataSource = dt;

        gr.DataBind();

    }

    protected void btn_chk_Click(object sender, EventArgs e)

    {

        string name=string.Empty;

        string phone = string.Empty;

        foreach (GridViewRow gvr in gr.Rows)

        {

            Label lbl_Name = gvr.FindControl("lbl_Name") as Label;

            Label lbl_phone = gvr.FindControl("lbl_phone") as Label;

           

            name += lbl_Name.Text+",";

            phone += lbl_phone.Text + ","; 

        }

        Response.Write(name);

        Response.Write("<BR/>");

        Response.Write(phone);

    }

It will look like :-
