I do not want to filter these records but show them and to not show 0 but ' ' (blank space)

Colin, When I was waiting for the answer I managed to do that in such a way you explained and it works! I can make a few changes after reading you responses. Many thanks for the explanation! ...very strange this singleton pattern :-) I had problems with saving settings but I created public method in singleton and called settings save method. Redards Ela

Such a life of developer :-)

There are project references and there are file references. It sounds like you're referencing the dll file directly. Why not just add a project reference? Logifusion[^] If not entertaining, write your Congressman.

Yes, it works now. I have only message on Console window: FormattedValueType property of a cell cannot be null. I tried to override FormattedValueType property but it doesn't not works. Another thing is sometimes I have to display animated gif in the cell. However when I want to animate gif I have to call Invalidate method which does not exist for the cell. Thanks Ela

I don't understand what you are trying to do and what you are doing. Maybe a code snippet would be helpful. Once you change the color of a cell it doesn't matter what else you do. only two letters away from being an asset

There is no problem anymore. Thanks Ela

Thanks for the answers. Anchoring is not a good solution. Controls are not resized. I have to do what I was affraid of. I will have to count the size of cotrols depends on size of panel. Thanks Ela

Kevin I have been founding in google etc. and I did not found anything usefull. However I am still looking for that. I consider to translate the C++ code to C#. I was going to do that in the future but maybe I will have to do it now. Ela

Thank you, it works. e_LA
