It is very important and urgent.I will appreciate if you can help me.

Answer 1

If you make your usercontrol inherit from System.Web.UI.WebControls.WebControl, then you can override the height and width properties, and do nothing in the setter.

So i created a new control, called it zzz, and changed its inheritance from System.Web.UI.UserControl to System.Web.UI.WebControls.WebControl. After that, this is what my code behind looks like:

public partial class zzz : WebControl
{
    public zzz()
    {
        base.Height = new Unit(100, UnitType.Pixel);
        base.Width = new Unit(150, UnitType.Pixel);
    }

    public override Unit Height
    {
        get { return base.Height; }
        set { }
    }

    public override Unit Width
    {
        get { return base.Width; }
        set {  }
    }
}

Try this:

Control Designer

public class CustomPanelDesigner : ControlDesigner
{

    public override bool AllowResize
    {
        get { return false; }
    }

}

Custom Control

[Designer(typeof(CustomPanelDesigner))]
public class CustomPanel : WebControl
{

    public CustomPanel() : base(HtmlTextWriterTag.Div) { }

    [Browsable(false), EditorBrowsable(EditorBrowsableState.Never)]
    public override Unit Width
    {
        get { return new Unit("100px"); }
        set { throw new NotSupportedException(); }
    }

    [Browsable(false), EditorBrowsable(EditorBrowsableState.Never)]
    public override Unit Height
    {
        get { return new Unit("100px"); }
        set { throw new NotSupportedException(); }
    }

}
