Dynamic Web Control Generation: Breaking Old Habits
Ah, for the days of classic ASP I thought early today. I need to dynamically generate some things from the server side so my old habits kick in and I thinks to meself:
<%
For i=0 to 10
Response.Write("<input id='dyn" & i & "'... >")
Next
%>
Doesn't quite work with ASP.NET. "Grrrr" I think to myself until I dig up an old post from The Code Project on the very subject. Two seconds and I realize ASP.NET is not only easier but more robust. For dynamic controls:
1. Use a placeholder control somewhere on your page:
<asp:PlaceHolder id="afronaut" Runat="server" />
2. Use some C# to access and build the controls collection of your placeholder:
private void Page_Load(object sender, EventArgs e){
for(int i=0; i<3;i++){
TextBox tx = new TextBox();
afronaut.Controls.Add(tx);
}
}
Once again it is proved that ASP.NET, while breaking old habits, surely is more robust. Probably the nicest thing I can think of right now is that it will work well with User Controls which are much more sophisticated than anything you could muster with the traditional Response.Write.
