Web Control Problem
-
I am trying to make a simple control with a button and a label. When you click the button the text of the label should change from "A" to "B" but it doesn’t work. Can anybody tell me what am I doing wrong? using System; using System.Web.UI; using System.Web.UI.WebControls; using System.ComponentModel; namespace WebControlLibrary1 { [DefaultProperty("Text"), ToolboxData("<{0}:WebCustomControl1 runat=server>")] public class WebCustomControl1 : System.Web.UI.WebControls.WebControl { private Button b; private Label l; public WebCustomControl1() { b=new Button(); b.Text="Click me!"; b.Click+=new EventHandler(this.b_Click); l=new Label(); l.Text="A"; } private void b_Click(object sender, System.EventArgs e) { l.Text="B"; } protected override void Render(HtmlTextWriter output) { b.RenderControl(output); l.RenderControl(output); } } }
