Databinding in asp.net using placeholder - asp.net

Question

I need to put a table in the div which contains textboxs and labels when someone click on a button.
Structure of table is as below...
<table>
<tr>
<td>
<label id="l1" text="adfa"></label>
</td>
<td>
<input type="text" id="t1">
</td>
</tr>
<table>
The no of rows can vary but the structure of a row will be same as here in the above table.
I am trying to use Placeholder but confused how to put all the stuff their...

Answer 1

Are you performing this operation client-side or server-side (for the latter, are you posting back to the server to update the response)? If the latter, using a ListView control would work perfectly, as you can define it as:
<asp:ListVIew .. ItemPlaceholderID="Items">
<LayoutTemplate>
<table>
<tr runat="server" id="Items" />
</table>
</LayoutTemplate>
<ItemTemplate>
<tr>
<td>
<label id="l1" text="afda"></label>
</td>
<td>
<input type="text" id="t1">
</td>
</tr>
</ItemTemplate>
</asp:ListView>
Then you can do:
ListView1.DataSource = //some data source
ListView1.DataBind()
The data can be empty rows just to populate the list initially, or some valid data. Some further references:

Answer 2

for (int i = 0; i < noofsubject; i++)
{
table.Width = 760;
TableRow tRow1 = new TableRow();
TableCell tCell11 = new TableCell();
tCell11.Text = "Subject " + i;
tRow1.Cells.Add(tCell11);
table.Rows.Add(tRow1);
}
PlaceHolder1.Controls.Add(table);
