Hi Sandeep,
You didn't specify whether you want this in a Windows Application or in a Web Application. I gues this is for a web application, because you have said 'Table'. Then, it can be done like this.
// Create DropDownList
DropDownList ddl = new DropDownList();
// Add items
ddl.Items.Add("Test1");
ddl.Items.Add("Test2");
ddl.Items.Add("Test3");
// Create TextBoxes
TextBox tb = new TextBox();
TextBox tb1 = new TextBox();
// Create TableCells
TableCell tc=new TableCell();
TableCell tc1=new TableCell();
TableCell tc2=new TableCell();
// Add Controls to TableCells
tc.Controls.Add(tb);
tc1.Controls.Add(tb1);
tc2.Controls.Add(ddl);
// Create TableRow
TableRow tr = new TableRow();
// Add TableCells to TableRow
tr.Cells.Add(tc);
tr.Cells.Add(tc1);
tr.Cells.Add(tc2);
// Create Table
Table Table1 = new Table();
// Add Row to Table1
Table1.Rows.Add(tr);
// Add Table1 to form
this.form1.Controls.Add(Ta
Like this we can add controls to a table. We can make this into one method which handles the button click event.
Then to retrieve values from the table, we have to traverse through the controls collection . But I think GridView will be the best solution for your problem. Reffer the Datavase tutorial available official ASP.Net site to learn how to add controls in the footer of the GridView.

Still if you want to use tables or if you are using Windows forms, please reply. I can help you.
