I want to let the user to color some words or phrases in a Textbox.
I thought the features of RadTextBoxControl would be good for that. (In between RadTextBox and RichTextEditor)
First handicap, I seem to have no influence on Block Creation, meaning on how the text is split into Blocks.
Than I assign a text like 'Dvoraks "New World" Symphony'
I get Blocks like
Not really what I wanted.
I found no other way than this:
Is this a good way, the recommanded way, to do custom splitting ?
Next: I could not attach a click event to a text block.
I found your Demo with a Button inside a TextBox (implementing ITextBlock on RadButtonElement) this works fine.
But something like this, is just never called (replacing the "new TextBoxElement" with "new TBE" in the above snippet of course)
Than I tried to subscribe to the Click-Event directly. (The Click Event of the TextBlockElement). No catched event either.
No success either: The GetElementAtPoint always returns the TextBoxElement, which is not wrong, but I want a children of it, a TextBlock.
So I need help on how to catch a click on a TextBlock,... than finally I can color my Block on user click (with setting textblock.ForeColor = Red f.e.).
Finally, what I'am missing also is Selecting a TextBlock. The Select Functions of TextBoxControl are all character based.
But has the TextBlock information about it's own position in the whole Text ? Is this the Offset/Length Property ? Documentation don't gives me any clue, if this is something measured in pixel, number of characters, or whatever.
So how do I something like textBoxControl1.Select(textblock) ?
