How to block resizing of column group header (quick fix on exception)
posted

I have column group and using row layout with groups.

When someone plays with group sizing (only when cursor is "resizeNWSE" ) exception is thrown.

How can I block resizing for entire column group?

    Hello Artur,

    I try to reproduce your issue in a small sample, but without success. Could you please tell me what is your current version and do you have any installed service release and which one. Please take a look at the attached video file where I try to reproduce your issue and if you think that I miss any specific steps, please write me.

    If you want to prevent Group resizing, then you could set  AllowCellSizing = None of that Group. Please take a look at the second part of attached video for more details.

    Let me know if you have any questions.

    Regards
