  Adapter For Asp:Image Control

  Jul 14, 2006 01:24 PM|LINK

  I have read this post: Adapter for Image
  What are the: RenderBeginTag, RenderEndTag and RenderContents methods?
  I will explain what i want to do:
  
  MyAspxPage.aspx
  <asp:image id="myImage" runat="server" cssSelectorClass="myClass" src="pig.jpg" alt="bla bla bla" />
  
  HTML source:
  <img id="myImage" class="myClass" src="pig.jpg" alt="blablabla" />
  
  I wrote this code:
  
   public class ImageAdapter : WebControlAdapter
      {
          Image image;
  
          protected override void RenderContents(HtmlTextWriter writer)
          {
              Image image = Control as Image;
              if ((image != null) &&
                  (image.Attributes["CssSelectorClass"] != null) &&
                  (image.Attributes["CssSelectorClass"].Length > 0))
              {
                  writer.Indent++;
  
                  writer.WriteBeginTag("img");
                  writer.WriteAttribute("src", Page.ResolveUrl(image.ImageUrl));
                  writer.WriteAttribute("alt", image.ToolTip);
                  writer.WriteAttribute("class", image.Attributes["CssSelectorClass"]);
                  writer.Write(HtmlTextWriter.SelfClosingTagEnd);
  
                  writer.Indent--;
                  writer.WriteLine();
              }
          }
  
          protected override void RenderBeginTag(HtmlTextWriter writer)
          {
              //
          }
  
          protected override void RenderEndTag(HtmlTextWriter writer)
          {
              //
          }
  }
  
  
  , but why did i implenet only the RenderContents method? which method i should implement for my purpose?

  Hey,

  RenderBeginTag and RenderEndTag can render a surrounding tag around the image you generated.  This could be a table or a div that surrounds it.
