I. Declare following globally:-

C#

DataTable mdtDescriptorText;
DataColumn objDcGetColoumns = new DataColumn();
DataRow objDrGetColoumns;

II. Create DataTable for Grid:

C#

private DataTable CreateDataTable()
{
    DataColumn col;
    mdtDescriptorText = new DataTable();
    col = new DataColumn("Column-1");
    mdtDescriptorText.Columns.Add(col);
    col = new DataColumn("Column-2");
    mdtDescriptorText.Columns.Add(col);
    col = new DataColumn("Column-3");
    mdtDescriptorText.Columns.Add(col);
    return (mdtDescriptorText);
}

III. Bind DataTable to GridView:

C#

private void AddNewRow(int intRowNumber)
{
    for (int i = 0; i < intRowNumber; i++)
    {
        objDrGetColoumns = mdtDescriptorText.NewRow();
        mdtDescriptorText.Rows.Add(objDrGetColoumns);
    }
    gridRow.DataSource = mdtDescriptorText.DefaultView;
    gridRow.DataBind();
}

IV. Now On Button click:

C#

protected void btnAddRow_Click(object sender, EventArgs e)
{
  CreateDataTable();
   foreach (GridViewRow gridItems in gridRow.Rows)
    {
        objDrGetColoumns = mdtDescriptorText.NewRow();
        TextBox txtBox1 = (TextBox)gridItems.FindControl("txtBox1");
        TextBox txtBox2 = (TextBox)gridItems.FindControl("txtBox2");
        TextBox txtBox3 = (TextBox)gridItems.FindControl("txtBox3");
        objDrGetColoumns["Column-1"] = txtBox1.Text;
        objDrGetColoumns["Column-2"] = txtBox2.Text;
        objDrGetColoumns["Column-3"] = txtBox3.Text;
        mdtDescriptorText.Rows.Add(objDrGetColoumns);
    }
  AddNewRow(1);
}

Here is your GridView:-

ASP.NET

<asp:GridView ID="gridRow" runat="server" AutoGenerateColumns="false">
            <Columns>
                <asp:TemplateField HeaderText="Column-1">
                    <ItemTemplate>
                        <asp:TextBox ID="txtBox1" runat="server"></asp:TextBox>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField HeaderText="Column-2">
                    <ItemTemplate>
                        <asp:TextBox ID="txtBox2" runat="server"></asp:TextBox>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField HeaderText="Column-3">
                    <ItemTemplate>
                        <asp:TextBox ID="txtBox3" runat="server"></asp:TextBox>
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>
        <asp:Button ID="btnAddRow" runat="server" Text="Add Row" OnClick="btnAddRow_Click" />

Good luck.
