I'd like to add an HTMLEditor control to my page dynamically in C#, but can't seem to find the syntax.  Any help?

TIA,
Joel

Here's some code I've used in the past

protected TextEditor textContent;
 
 
textContent = (TextEditor)LoadControl("~/controls/TextEditor.ascx");
textContent.HtmlEncode = false;
textContent.TextRenderMode = "Raw";
textContent.Width = 500; //default values for size of the editor
textContent.Height = 500; //default values for size of the editor
textContent.ChooseMode = true;
 
//a placeholder on the ASCX side
phTextEditor.Controls.Add(textContent);
 
textContent.Text = "some content"

Excellent!  Now my problem is that when I try to set the value of the text, I get "Object reference not set to an instance of an object."

input = (TextEditor)LoadControl("~/controls/texteditor.ascx");
 ((TextEditor)input).Text = existingValue;

TIA,
Joel

So it turns out that you can't set the text before the control has been initialized. I added an Init event handler, but apparently I can't give it any EventArgs, so I ended up storing my value in a hashtable and setting it in the EventHandler. Is there a different kind of event handler that I can use to pass in the value? Next question. In the HTMLEditorProvider ConfigDefault.xml file I'm adding a CSS stylesheet via the CssFiles property, and a javascript function to call via the OnClientLoad property. How can I get this instance of the TextEditor to pick those up?

Sorry, I forgot to mention the load order, when loading the code I used in the example it was all done in OnInit for the control, before base.OnInit was called.

As for your CSS changes, if you're making changes to the way the TextEditor control for the HTML module (or other instances of the editor), it should be loading the same control for the new module if you use the code I provided. I take it you're not seeing that?
