Title Body

I know this question has been asked thousands of times, and I've struggled with it before, but for some reason, I can't accomplish what I want to accomplish... I have a dynamically added LinkButton that when clicked will dynamically add a control (in this example, a textbox) to the same panel. The intent is to continuously add on as many controls as times the LinkButton was clicked (i.e. I click it once, one box, then another click will give me 2 boxes, another click adds a 3rd). In the code below, I use the current date and time serialized to create a unique ID for each textbox control. When I execute the code, clicking "Add Filter" will generate a new textbox, but once clicked again will create a new one, and dispose of the one before it. Instead, I want to persist the previous textbox as well as any data submitted within it. Your help is appreciated. In the aspx: <asp:Panel ID="pnlFilter" runat="server"> </asp:Panel> In the aspx.cs: protected void Page_Init(object sender, EventArgs e) { LinkButton lb = new LinkButton(); lb.ID = "lbAddFilter"; pnlFilter.Controls.Add(lb); lb.Text = "Add Filter"; lb.Click += new EventHandler(lbAddFilter_Click); } void lbAddFilter_Click(object sender, EventArgs e) { TextBox tb = new TextBox(); tb.ID = "tb" + DateTime.Now.ToBinary().ToString(); pnlFilter.Controls.Add(tb); }
