Solution 1

First Check Rowcount of grid

C#

CurrentRow = dg.Rows.Count - 1;

then add data to grid

C#

dg.Rows[CurrentRow].Cells["YourFieldName1"].Value = txtText1.Text;
dg.Rows[CurrentRow].Cells["YourFieldName2"].Value = txtText2.Text;

all rows have almost same code

<asp:TemplateField HeaderText="Add" ItemStyle-VerticalAlign="Middle" ItemStyle-Width="30%" HeaderStyle-HorizontalAlign="Left">
<itemtemplate>
<asp:Button ID="btnAdd" CommandName="Add" Text="+" runat="server" onclick="btnAdd_Click"/>

this is the template for button

first add "text box","datagrid" and "button"

C#

in button click(write this code)
{

DataTable dt = new DataTable();
            dt = new DataTable();
            dt.Columns.Add("Val1");
           

            DataRow dr = dt.NewRow();
            dr["Val1"] = TextBox1.Text;
          
            dt.Rows.Add(dr);

            GridView1.DataSource = dt;
            GridView1.DataBind(); 
}
