Es geht sogar noch cooler wenn du von Image ableitest:
using System;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.ComponentModel;
namespace test
{
/// <summary>
/// Summary description for WebCustomControl1.
/// </summary>
[DefaultProperty("Text"),
ToolboxData("<{0}:MyButton runat=server></{0}:MyButton>")]
public class MyButton : Image
{
//Hier sperre ich das Setzten der ImageUrl
public override string ImageUrl
{
get
{
return base.ImageUrl;
}
}
[Bindable(true),
Category("Appearance"),
DefaultValue(true)]
public bool Expanded
{
get
{
return this.expanded;
}
set
{
this.expanded = value;
}
}
private bool expanded = true;
[Bindable(true),
Category("Appearance"),
DefaultValue("")]
public string ImageUrlExpanded
{
get
{
return this.imageUrlExpanded;
}
set
{
this.imageUrlExpanded = value;
}
}
private string imageUrlExpanded = "";
[Bindable(true),
Category("Appearance"),
DefaultValue("")]
public string ImageUrlCollapsed
{
get
{
return this.imageUrlCollapsed;
}
set
{
this.imageUrlCollapsed = value;
}
}
private string imageUrlCollapsed = "";
protected override void OnLoad(EventArgs e)
{
base.OnLoad (e);
base.ImageUrl = (this.expanded) ?
this.imageUrlExpanded : this.imageUrlCollapsed;
}
}
}
