Hi this may suit your need as per my knowledge:
You couldnt display a gridview without a bound filed , so u should have a dummy row that is created in run time and also a dummy column in all rows.
Client side code for gridview and button :
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" >
<Columns>
<asp:BoundField DataField="RowNumber" HeaderText="Row Number" />
<asp:TemplateField HeaderText="Name">
<ItemTemplate>
<asp:TextBox ID="txtName" runat="server"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="City">
<ItemTemplate>
<asp:TextBox ID="txtCity" runat="server"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
<asp:Button ID="Button1" runat="server" OnClientClick="return AddNewRecord();" Text="Button" />
javascript:
---To add new row--
function AddNewRecord() {
var grd = document.getElementById('GridView1');
var tbod = grd.rows[0].parentNode;
var newRow = grd.rows[grd.rows.length - 1].cloneNode(true)
tbod.appendChild(newRow);
addvalue();
return false;
}
---To add textboxvalues---
function addvalue() {
var grd = document.getElementById('GridView1');
var txt = document.getElementById('TextBox1');
var id = 2;
var no=grd.rows.length - 1
grd.rows[no].cells[2].childNodes[0].value = txt.value;
}
-----Here i have added for one cell and u can add as per ur wish----
Server side code for gridview on page load event---
Dim dt As DataTable = New DataTable
Dim dr As DataRow = Nothing
dt.Columns.Add(New DataColumn("RowNumber", GetType(System.String)))
dt.Columns.Add(New DataColumn("Column1", GetType(System.String)))
dt.Columns.Add(New DataColumn("Column2", GetType(System.String)))
dt.Columns.Add(New DataColumn("Column3", GetType(System.String)))
dt.Columns.Add(New DataColumn("hdf", GetType(System.String)))
Dim i As Integer
dr = dt.NewRow
dr("RowNumber") = 1
dr("Column1") = String.Empty
dr("Column2") = String.Empty
dr("Column3") = String.Empty
dt.Rows.Add(dr)
ViewState("CurrentTable") = dt
GridView1.DataSource = dt
GridView1.DataBind()
