Textbox Highlighting Text and Replacing

[gi11ies]

Im trying to make a very basic text editor, that has image buttons for formatting the text. Just now I have if so if you want bold text ... you press the relevant image button and [[]b] goes into the textbox and when you finish the bold text you click it again [[]/b] goes into the text box.

I use this code.

Sub btnBold_Click (Sender as Object, e as ImageClickEventArgs)
	If Session("boldText") = "boldOff" then
		Dim textForBold As String = txtContent.text
		Dim textBoldStart As String = textForBold + "[[]b]"
		txtContent.text = textBoldStart
		lblStatus.Text = "Text Entry is Bold. (click on Bold Text button again to end Bold Text)"
		Session("boldText") = "boldOn"
	Else
		Dim textForBold As String = txtContent.text
		Dim textBoldEnd As String = textForBold + "[[]/b]"
		txtContent.text = textBoldEnd
		lblStatus.Text = "Text Entry is Normal."
		Session("boldText") = "boldOff"		
	End If
End Sub

I do replaces when the page is opened, ie [&#91;]b] is <b> and [&#91;]/b] is </b>.

What I want to do is use the cursor to highlight text in the textbox and press the bold image button and it will automatically make that text bold, by doing a replace in the textbox of the selected text putting in [&#91;]b] and [&#91;]/b]

for example

In the textbox

The dog ran after the ball.

If I selected 'dog ran after' so its highlighted, and then pressed the bold image button I created, it replaces the text to.

The [&#91;]b]dog ran after[&#91;]/b] the ball.

Does anyone have any tips on how to do this?

You'll have to use javascript to do that. Try asking in the javascript forum (forum216)

Gillies - After you post this over at Javascript do a general search on this - I have seen several times sites that have this type of javascript code ready to go.
