Hello,

What you could try is the following:

this.ultraSpellChecker1.ShowSpellCheckDialog(desired control);

But since I am not aware of the "Tx Text Control" I could not say if this would work or not.

Please take a look at the following link where you would be able to find more information about using our UltraSpellChecker:

http://help.infragistics.com/NetAdvantage/WinForms/2011.1/CLR2.0/?page=Win_WinSpellChecker_Using_WinSpellChecker.html

If you have any other questions please feel free to ask.

The Tx Text Control API has a TextControl class which derives from TextControlBase class which ultimately derives from System.Windows.Forms.Control class.

I tried launching the Spell Check dialog for the TextControl using the following line of code:

      this.ultraSpellChecker1.ShowSpellCheckDialog(this.textControl1);

but got an exception:

  System.ArgumentException was unhandled

  Message="The specified object was not of the correct type.\r\nParameter name: spellCheckTarget"

  Source="Infragistics2.Win.UltraWinSpellChecker.v10.3"

  ParamName="spellCheckTarget"

Then I tried to do something like this:

this.ultraSpellChecker1.SetSpellCheckerSettings(this.textControl1, new SpellCheckerSettings());

but again got an exception:

                System.ArgumentException was unhandled

                Message="The specified control cannot have SpellCheckerSettings applied to it.\r\nParameter name: control"

Source="Infragistics2.Win.UltraWinSpellChecker.v10.3"

ParamName="control"

Please advise how can I get the UltraSpellChecker to work with this control…
