Resizing controls in the designer

10/27/2003 1:32:08 PM

0/0

I have developed a composite control which contains a Table:



[Designer( typeof(CompositeControlDesigner) ) ]


	public class TestControl : WebControl, INamingContainer


	{


		public TestControl()


		{


		}





		public override ControlCollection Controls


		{


			get


			{


				EnsureChildControls();


				return base.Controls;


			}


		}





		protected override void CreateChildControls()


		{





			Table t = new Table();


			TableRow tr = new TableRow();





			TableCell td = new TableCell();


			TableCell tdtwo = new TableCell();





			td.Width = Unit.Percentage( 80 );


			tdtwo.Width = Unit.Percentage( 20 );





			td.Text = "cell one";


			tdtwo.Text = "cell two";





			tr.Cells.Add( td );


			tr.Cells.Add( tdtwo );





			t.Rows.Add( tr );





			this.Controls.Add( t );


		}


	}

The designer for this control looks like so:



public class CompositeControlDesigner : ControlDesigner


	{


		public override string GetDesignTimeHtml() 


		{


			ControlCollection controls = ((Control)Component).Controls;


			return base.GetDesignTimeHtml();


		}





		public override void Initialize(IComponent component) 


		{


			if (!(component is Control) &&


				!(component is INamingContainer)) 


			{


				throw new ArgumentException(


					"Component must be a container control.", 


					"component");


			}


			base.Initialize(component);


		}


	}

The problem is when you grab the handles in the designer and resize the control, the contents do not resize as you would expect. If you save and load the page in the browser it works fine and the contents are the correct size but it doesn't get refreshed in the designer properly.

Also, where and why does the SPAN control get added to the Controls collection?
