Custom WebControl - Children, Properties, etc.

Jan 20, 2006 08:30 PM|LINK
I apologize in advance, I feel sure this question has been answered many many times. I cannot, however, seem to find the magical combination of search keywords to yield my answer.

I am trying to create a custom webcontrol which has some children, which then have properties. Here is something similar to what I want my webcontrol to do:
```
<uc1:MyControl ID="myControl1" runat="server">
   <uc1:MyItem Label="Label1">
      Just some text.
      <asp:Label ID="lbl_Test1" Text="Test1" runat="server" />
   </uc1:MyItem>
   <uc1:MyItem Label="Label2">
      Some more text.
      <asp:Label ID="lbl_Test2" Text="Test2" runat="server" />
   </uc1:MyItem>
</uc1:MyControl>
```
In a way this is a bit similar to DropDownList (ListItem). Except the example above has children which can also contain controls. The example above could be used to ultimately create a custom TabStrip / Tab control.

My question is kind of general. How do you create a webcontrol which can contain children, which have properties and which can also contain children?

Ok, I think I got this solved. Consider this:

test.aspx:

<html>
   <body class="BODY">
      <form runat="server" id="mainForm" method="post">
         <uc1:Tabs runat="server">
            <Tab Label="Tab1">
               <asp:Label ID="myLabel1" runat="server">Label1</asp:Label>
            </Tab>
            <Tab Label="Tab2">
               <asp:Label ID="myLabel2" runat="server">Label2</asp:Label>
            </Tab>
         </uc1:Tabs>
      </form>
   </body>
</html>

Tabs.cs

public class Tabs : WebControl 
{
   private ArrayList ourTabs;
 
      public Tabs()
      {
         ourTabs = new ArrayList();
      }
 
      public TabItem Tab
      {
         set
         {
            ourTabs.Add(value);
         }
      }
 
      protected override void Render(HtmlTextWriter output)
      {
         foreach (TabItem thisTab in ourTabs)
         {
            output.Write("Label: " + thisTab.Label + "<br>");
         }
      }
   }
}
 
public class TabItem : Control, INamingContainer
{
   public string Label = "";
   
   public TabItem()
   {
   }
}
