URGENT c# Web Text Box

Hi i have to create a text box to work on the web which will allow the user to Edit Text Files used as web content,

How do i get the following working

After a user has Selected a section of text from the text box and pressed the bold tool (which i have used an imagebutton for) how do i get it to do the following.

Wrap the selected text within the html bold tags<b></b>
hide the html tags and display the text as bold within the textBox

Once the user has finished altering the text within the TextBox they save the Text back to the file with the html Tags in the correct place.

CAN SOMEONE URGENTLY HELP
Regards

I am not sure, but I would pray there is a "Selected" value for the text box if there is a simple way to do this. Much like a drop down menu. Then you could insert into 1 before and 1 after the textbox a <B> </B>
I just wanted to give you a quick response of somekind to help you on your way. Hopefully someone has a better solution.

Do you need to do it on the client side or serve side? Is the <b> tag the only one you need to support?
I'm almost certain you can't do it entierly on the server side, so some client side javascript must be used.

If you need to handle more than just <b> tag i would suggest using an already made html editing control. There are a thon of them available ranging from free to very expencive.

One that i used on a recent project is a free RichText Editor control (http://www.exporttechnologies.com/?product=RichTextEditor&version=0.92) I was able to put it in my pages instead of textbox after the fact and it worked flowlesly. I know this sounds like an ad for RichText Editor but i'm not affiliated with them.. just a happy customer.
See the demo at this page: http://www.exporttechnologies.com/softwaredownloads.asp

Anyways, hope this helps.

You will need a IFrame as the editor.
Then call the DHTML execCommand functions



<IMG onclick="ToBold(editorwindow);" src="images/bold.gif" width="23" unselectable="on">

<IFRAME id="editor" onblur="CloneData();" name="editorwindow" width="100%" height="100%">


function ToBold(editor) {
      TxtFormat(editor,'bold');
}
function TxtFormat(editor,format){
editor.document.execCommand(format,'',null);
}
