    Urgent: Custom Control

    Hello!

    I am developing a custom server control that inherits from Hyperlink web
    control.

    I defined 2 new properties - ImageWidth and ImageHeight. My qustion is, how
    I can override Render method so if Hyperling ImageUrl is set then add
    ImageWitdh and ImageHeight attributes to image.

    Thank you!
    James

      Hi James:

      My suggestion would be to add the attributes to the Attributes
      collection of the control - the inherited functionality will take care
      of rendering the attributes you specify in this collection.

              Hi James:

              You might want to take a look at Reflector [1] and see the source code
              to for rendering the HyperLink (it's in RenderContents) . The code is
              pretty straightforward , and you could actually override the method and
              duplicate the code to add a couple lines and set the Image control
              properties.

              Do you know how to override a method? What language are you using?
