RichTextBox (.NET Winforms) problem (or alternative)

Question

I have a problem with .Net's RichTextBox control. It seems that it doesn't support table cell formatting, which is funny because most of the time I create tables I want the cell contents to be right-aligned (numbers, currency). If I try to open a WordPad document in RichTextBox, it ignores (and actually removes) the commands for cell alignment. I tried several workarounds but didn't succeed. Can anyone think of an idea to fix this? (without using fixed-width fonts and spaces) This would be the best solution since other code is working fine already, so if only thing needed is a dirty hack, it would be great. Or is there an open source alternative for .Net Rich Text Editor you can recommend? I need a user control I can embed in my Windows form and access the contents programmatically (create content, or append something). I have searched the web for some time but found only web (Ajax/Javascript) controls. There are also HTML WYSIWYG editors which I could use, but they are all basically…

Accepted Answer

If you are still going down the .net winforms path then inherit from RichTextBox and add the following code, it will transform the RichTextBox into something "useable":

```
[DllImport("kernel32.dll", CharSet = CharSet.Auto)]
static extern IntPtr LoadLibrary(string lpFileName);

protected override CreateParams CreateParams
{
    get
    {
       CreateParams cparams = base.CreateParams; 
       if (LoadLibrary("msftedit.dll") != IntPtr.Zero)
       {
          cparams.ClassName = "RICHEDIT50W";
       }
       return cparams;
     }
}
```
