c# - Add asp:Button from codebehind

Question

I'm building a in codebehind. The table is a listing of a database records (one record per row) and I neeed to add a delete button for each row. To do that, I of course need to build a button with a unique ID for that. To do that, I came up with the following ... which doesn't work. Any tips on how to get this working?

Button deleteButton = new Button();
deleteButton.ID = "deleteStudentWithID" + singleStudent.ID.ToString();
deleteButton.Text = "X";

string row = "<tr>";
row += "<td class="style5">"+deleteButton.ClientID +"</td>";
row += "</tr>";

Your problem is that you're adding only the ClientID of your control to the html and not adding the control to the page itself.

Controls.Add(new LiteralControl("<table>"));

foreach(var singleStudent in students)
{
    Controls.Add(new LiteralControl("<tr>"));

    //Code to add other columns

    Button deleteButton = new Button();
    deleteButton.ID = "deleteStudentWithID" + singleStudent.ID.ToString();
    deleteButton.Text = "X";

    Controls.Add(new LiteralControl("<td class="style5">"));
    Controls.Add(deleteButton);
    Controls.Add(new LiteralControl("</td></tr>");
}

Controls.Add(new LiteralControl("</table>"));
