Validation of Drop-down list

Hi, I have a problem in my Aspose.Grid web solution.

Some columns in my worksheet are validated by myself (in Aspose I define the validation type as AnyValue for these cells), but I also use the drop-down feature to validate the other columns (Validation type = List).

In cells that I validate by myself, when the user types a value not allowed for that column, then the application DOES NOT clear the content of the cell, and also mark it with the red crosses in the background.

What I need is that, when the user types something wrong in the columns that are validated by the DropDown List feature, the Aspose automatically put the red crosses on the background of that cell together with the wrong value (without erasing it from the cell) and also I have the option to know if this cell value is wrong or not.

I will appreciate if you could help me!

Thanks in advance,


Well, I am not very clear about your need. Could you create a sample test project, zip it and post it here with details what do you want and show the issue around.

Thank you.
