Rich Text Box

I am using rich text box control in my vb.net windows application to format some user define text formatting.

I placed 3 buttons for bold, italic, & underline to change text formatting.

These buttons perform very well separately. But when want to use more than one option at same text, latest formatting option overwrites previous formatting.

Give Me Any Suggestion Please Help Me.

re: Rich Text Box

Could you use a global bool value to show if the button is clicked, Then do some checks so
after you have defined these you would set these true and false in the button click events
dim b1 as bool = false // bold
dim b2 as bool = false etc etc /italics


private sub checkButtonsClicked
if b1 = true and b2 = true then
//your text or text box properties italics bold set to true
end sub

you would have to cover all the combinations but that the quickest idea that came to me. Sorry i'm not amazing at programming

re: Rich Text Box

very simple way
set some global bool variables
on buttonclick set these to either false or true
do some checks so if b1 = true and b2 = true then set properties for bold and italics
as i said very simple but possibly not the best way

re: Rich Text Box

A flexible way of this is to use the FontStyle as a flag i.e. if the font should be bold and underlined the style is FontStyle.Bold And FontStyle.Underline.

A very thrown together implementation would be:

This assumes that the RichTextBox control is called testRich. Calling these procedures is done by:
The And, Or & XOr (Exclusive Or) are all bitwise operator. A brief tutorial can be seen here.

Using this method means that you can use any of the FontStyle values.

Thanks for your interest.
But these answers are not helping me.

but finally i have found the solution of my problem.
I used following code for bold event


Underline & italic events are same as this code
