I have here a small problem with a dynamically generated buttons and their event handler in asp.net. I generate a flexible table with additional Buttons for special users. The buttons will generate dynamically, which works fine. But I can’t get the event handler to work. Here are some pieces from my code: Build the button (In an own function). … Button ButtonChange = new Button(); ButtonChange.Text = "Change"; ButtonChange.ID = "change_" + i.ToString(); ButtonChange.Font.Size = FontUnit.Point(7); ButtonChange.ControlStyle.CssClass = "button"; ButtonChange.Click += new EventHandler(test); … And void test(object sender, EventArgs e) { // Do some stuff } My Page_Load is empty. But the program won’t jump to test, if I click the button. What’s going wrong? Edit!!! The problem is that I don’t know at start how many rows I get from my sql query back. For every row I will add a delete and a change button. I call in my program a method which builds the result as a table. In this method, I check if the current user is an AdminUser and if he is, I will call buildAdminButtons function. Here, I create the buttons in a new column, for every row. How could I get this in OnLoad? private void buildAdminButtons(TableRow tempRow, int i) { Button ButtonDelete = new Button(); Button ButtonChange = new Button(); TableCell change = new TableCell(); TableCell delete = new TableCell(); ButtonChange.Text = "Change"; ButtonChange.ID = "change_" + i.ToString(); ButtonChange.Font.Size = FontUnit.Point(7); ButtonChange.ControlStyle.CssClass = "button"; ButtonDelete.Text = "Delete"; ButtonDelete.ID = "delete_" + i.ToString(); ButtonDelete.Font.Size = FontUnit.Point(7); ButtonDelete.ControlStyle.CssClass = "button"; change.Controls.Add(ButtonChange); delete.Controls.Add(ButtonDelete);
