I am using UltraGrid 10.3. When I click on a check box header on the firstband, Click event is duplicating the child bands as shown below. One with formatted rows other with not formatting ( without intialization). Please advise, is this control issue / bug. If needed, I can create small project to demo this. I can simulate this. Please advise.
I'm not clear on what you mean by "duplicating the child bands". The grid's header checkbox functionality simply checks the checkboxes in that column, so if unwanted rows are being added somehow, it has to be your code that is doing that. If you have a sample project, attach it here and we'll try to help.
