Dynamically Creating ImageButtons

what I want to do is create the following

 for(int i = 0; i < numberOfAnswers; i++){
        imgString = imgString + "<td><asp:ImageButton id='" + questionName + "' ImageURL='Styles/unClicked.png' runat='server' /></td>";
    }

but when I use HTMLTextWriter to write the string out, it attualy writes the tags out exsatly instead of converting them to html.

Do I have to write them in HTML and use javascript to call a method, or is there a way I can do this without getting that complicated?

You should instantiate the ImageButton objects and add them to the control structure of your page. They will then render their own markup, register for events, etc.

for(int i = 0; i < numberOfAnswers; i++){
    var ib = new ImageButton();
    var td = new HtmlTableCell();

    // assign values, like ID, Image URL, event handlers, etc. here
    ib.ID = "button_" + i;
    ib.ImageUrl = "foo";
    ib.Click += ( sender, e ) => {
        // anonymous event handler
    };

    // "container" can be any control on the page, such as a table row
    container.Controls.Add( td );
    td.Controls.Add( ib );
}

    for (var i = 0; i < 5; i++)
    {
        ImageButton imgBtn = new ImageButton();
        imgBtn.ID = "question" + i;
        imgBtn.ImageUrl = "Styles/unClicked.png";

        PlaceHolder1.Controls.Add(imgBtn);
    }

PlaceHolder1 is the runat server control, where u'd like to add ur generated buttons.
