Hey guys, I´ve got a custom server control and it works like I want it to, However, in design view, it won´t work.

I´ve got the following IDesigner:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ComponentModel;
using System.ComponentModel.Design;
using System.Web.UI;
using System.Web.UI.Design;
using System.Web.UI.WebControls;
using System.Resources;

namespace CustomTools
{
    class CustomButtonDesigner: ControlDesigner
    {
        public override string GetDesignTimeHtml()
        {

            
            string designTimeHtml = null;
          

                designTimeHtml = "<div style=\"width:120px;height:40px;background-color: gray;color: white; font-weight: bold;text-align: center; border:2px solid white;\">"+ this.ID.ToString() +"</div>";

              
          

            return designTimeHtml;
        }

        public override void Initialize(IComponent component)
        {

            if (!(component is Control) && !(component is INamingContainer))
            {
                throw new ArgumentException("component must be a container control");
            }


                base.Initialize(component);
            
            

            
        }





    }
}

AS you can see, I am simply loading a Div with a background color adn the name of the control. Nothing special.

When I load te control in DesignView, if it´s by itself it loads properly, however, if I place it inside an ASP table or a Placeholder, it will give me the following error in design view it will make these not render in design view (again, it all works as expected on runtime)

For example, I´ve got one instance of my control by itself, and below it, I have a Table with an instance of my control inside.

as shown:

  <cc1:RDCButton ID="CustomButton1" runat="server" ButtonText="asdf" ControlLock="False" alarmString="0000000000" CssClass="buttonClass" Height="40px" Width="120px"></cc1:RDCButton>
        <br />
        <br />
        <asp:Table ID="Table1" runat="server">
            <asp:TableRow runat="server">
                <asp:TableCell runat="server">
                    <cc1:RDCButton ID="CustomButton2" runat="server" ButtonText="asdf" ControlLock="False" alarmString="0000000000" CssClass="buttonClass" Height="40px" Width="120px"></cc1:RDCButton>
                </asp:TableCell>
            </asp:TableRow>
        </asp:Table>

On DesignTime, the CustomButton1 control, which is by itself, will render properly, while the CustomButton2, which is inside the table, will throw this error:

Error Rendering Control - Table1

An unhandled exception has ocurred.

Object reference not set to an instance of an object.


If I then place the CustomButton2 in a Placeholder, I will get:

Error Rendering Control - PlaceHolder1

An unhandled exception has ocurred.

Object reference not set to an instance of an object.

Any Ideas as to what may be causing this? How can i work around it?

All help is appreciated!
