This is a bit of an odd request / question.

In our implementation of the UltraGrid, we allow columns to be inserted by the user with a formula attached to them.

To set the formula we show the Formula Builder Dialog. 

It's been noticed that if a user enters a formula with a syntax error, despite being warned that formula is invalid, if the user chooses to continue anyway a "scary to the end user" Infragistics error dialog appears (twice actually, duplicates) of the format:

"A syntax error occured while compiling a formula for: //DisplayGrid/results0/Column1

The error is:

Unexpected end of file, on line: 1 column 10"

This error dialog occurs after the following line of code:

formulaProvider.Formula = formulaBuilderDialog.Formula

Obviously the user was warned up front that the formula contained a syntax error.  They also are acknowledging they understand this by choosing to continue.  However, I've been asked if there is anything that can be done to not show the error dialog.

I understand I could check the .HasSyntaxError property after the dialog returns and if it's true, simply not assign the formula.  But by doing so, it'd be incredibly confusing to the user to initially allow them to use an invalid formula, then immediately follow that by throwing it away.

What I'm looking for, in order of priority is:

1) Not show the infragistics compilation error at all

2) If that's not possible, at least only show the compilation dialog once.

Any help would be appreciated.  If the answer is "nothing can be done if you're going to use the provided FormulaBuilderDialog", at least I can present that to product management.

Thanks,
