Hello, we are using the RIchTextBox control and enabled the Caps Spell Checker. We are using PRISM MVVM pattern and using the PRISM  InteractionRequest to open dialog boxes.

We are using the version Telerik UI  for WPF 2021 _1_325

Please find the profiler memeory analysis, below.

This issue looks similar to the one identified in 2012, please see link below,

Hi,

is it possible to translate the buttons in the RadSpellChecker-Dialog (see Screenshot) into german?

Regards,

Frank.

I am using RadSpellChecker to spell check a WPF TextBox.  In a different area of my application, I am using RadRichTextBox and I have a custom dialog for spell checking.  When I spell check the WPF TextBox, I get the built-in spell checking dialog instead of my custom dialog.  Is there a way to also use the custom dialog when spell checking a WPF TextBox?

Hello,

I am trying to spellcheck certain controls in our project. However, whenever I make a call to RadSpellChecker.Check(this.textBox1, SpellCheckingMode.WordByWord), the corresponding spell checking window does not seem to load/open properly (there is just a transparent footprint of the window). Our project uses implicit themes  and we suspect this is causing the problem. On a small test project (no implicit themes), the RadSpellChecker seems to work fine. Thank you.

Hi all,

I am starting a spellchecker on a textbox createad at run time like this:

I see multiple threads on client/server solutions, but no help on WPF on this message "the spelling check is complete"

So how to remove or hide it, both in:

1. on the main spellcheck window, when finished and waiting for "OK"
2. on the small final popup window with warning triangle (similar to a MessageBox)

Both have almost not added value, and are very user-annoying if you call the spellcheck frequently in a loop

Any code or trick for that in WPF ?

Thanks,

Favrice

Hello, we are using a RadRichTextBox with SpellChecker dialog.  When a word is added to the custom dictionary, either through the context menu or the SpellChecker dialog, the AddWord event is fired correctly.  However, when a word is deleted from the dialog, or the Delete All is selected, no event is fired.  We are capturing both RemoveWord and DataChanged events, but they are not called.  Our current version of controls may be older, so if this was fixed in a later version, please indicate that so we can proceed accordingly.

Thanks for your help.

Hello, I need help about italian spell checking. 

First of all, download the zipped file from here:
http://download2.anastasis.it/software/fabrizio/TestTelerikSpellChecker.zip

it's a minimal WPF application using your current R3 2016 UI for WPF libraries, that reproduces the uncorrect behaviors. It has a custom minimal dictionary extracted from our 2 million words italian dictionary.

This mini-dictionary contains ALL the words written in the embedded test document.

---BEHAVIOR 1: Initial spellchecking

Starting up the application, only the first sentence seems completely correct.

Line 1: "Questa è una prova" is ok.

Line 2: "Dov'è" and "Quand'è" are marked wrong. "Cos'è? cos è!" are ok only because there's "cos" in the dictionary (cosine math function). We can't put "quand" and "dov" in the dictionary because they aren't correct single words in italian.

Line 3: "Prova dell'albero." is ok, but "nell'albero" and "sull'albero" are marked wrong.

Line 4a-b-c: Any order of the 3 elements results in "dell'albero" right and the others wrong. But they are all in the dictionary!

---BEHAVIOR 2: Suggestions word extraction

Problem 1:
Right-click with cursor on line 2, over the "o" in "Dov'è". First suggestion is "Dov'è", if you click it, the resulting word will be "Dov'è'è". So, it seems that the spellchecker treats the apostrophe ' character as delimiter, that's wrong in italian because "Dov" is wrong and only "Dov'[Vowel]*" is right. Same applies with thousands of different word that get truncated on the following one. 

Problem 2:
Now for the black magic: Undo with Ctrl-Z, select whole "Dov'è" word and right-click it: no suggestions supplied (correct). Then, click in the editor to dismiss the context menu and roll the mouse wheel. Refresh now shows as correct the entire selection that was previously marked wrong.
Plot twist: Put the cursor after "è" in "Dov'è" and press space: "Dov'è" is marked wrong again.

But in English, all the words like "isn't", "don't", "we're" etc are marked as correct. So what's the problem with italian spell checking?

I really hope to get help from you, because the spell checker is a paramount function for our application.

Thanks in advance.
