Question

I know this is a dumb question. For some reason my mind is blank on this. Any ideas?

Sorry should have been more clear.

Using a HtmlGenericControl to pull in link description as well as image.

 private void InternalCreateChildControls()     {         if (this.DataItem != null && this.Relationships.Count > 0)         {             HtmlGenericControl fieldset = new HtmlGenericControl('fieldset');             this.Controls.Add(fieldset);             HtmlGenericControl legend = new HtmlGenericControl('legend');             legend.InnerText = this.Caption;             fieldset.Controls.Add(legend);              HtmlGenericControl listControl = new HtmlGenericControl('ul');             fieldset.Controls.Add(listControl);              for (int i = 0; i < this.Relationships.Count; i++)             {                 CatalogRelationshipsDataSet.CatalogRelationship relationship =                     this.Relationships[i];                  HtmlGenericControl listItem = new HtmlGenericControl('li');                 listControl.Controls.Add(listItem);                  RelatedItemsContainer container = new RelatedItemsContainer(relationship);                 listItem.Controls.Add(container);                  Image Image = new Image();                 Image.ImageUrl = relationship.DisplayName;                     LinkButton link = new LinkButton();                 link.Text = relationship.DisplayName;                   ///ToDO Add Image or Image and description                 link.CommandName = 'Redirect';                 container.Controls.Add(link);             }         }     } 

Not asking anyone to do this for me just a reference or an idea.

Thanks -overly frustrated and feeling humbled.

I’m assuming you want to generate an image dynamicly based upon an url.

What I typically do is a create a very lightweight HTTPHandler to serve the images:

using System; using System.Web;  namespace Example {       public class GetImage : IHttpHandler     {          public void ProcessRequest(HttpContext context)         {             if (context.Request.QueryString('id') != null)             {                 // Code that uses System.Drawing to construct the image                 // ...                 context.Response.ContentType = 'image/pjpeg';                 context.Response.BinaryWrite(Image);                 context.Response.End();             }         }          public bool IsReusable         {             get             {                 return false;             }         }     } } 

You can reference this directly in your img tag:

<img src='GetImage.ashx?id=111'/> 

Or, you could even create a server control that does it for you:

using System; using System.Web; using System.Web.UI; using System.Web.UI.WebControls;  namespace Example.WebControl {      [ToolboxData('<{0}:DynamicImageCreator runat=server></{0}:DynamicImageCreator>')]     public class DynamicImageCreator : Control     {          public int Id         {             get             {                 if (ViewState['Id' + this.ID] == null)                     return 0;                 else                     return ViewState['Id'];             }             set             {                 ViewState['Id' + this.ID] = value;             }         }          protected override void RenderContents(HtmlTextWriter output)         {             output.Write('<img src='getImage.ashx?id=' + this.Id + ''/>');             base.RenderContents(output);         }     } } 

This could be used like

<cc:DDynamicImageCreator id='db1' Id='123' runat='server/>
