Hi Mike,

>Those four properties you're having trouble with belong to the System.Windows.Forms.DataGrid, not the mmDataGrid. Can you duplicate the same behaviour when using the regular DataGrid? Or just check out the MM code and see if there's anything going on there.

Just because they are default properties doesnt mean that the framework doesnt have a problem. I'm not saying that there is a problem with the framework, but since I'm using the latest version 1.4.1, I'm considering the possibility that the install for 1.4.1 might have a problem.

I'm not saying something isnt messed up on my machine, but I am not experiencing the problem when using the DataGrid class (nor the combobox problem I've mentioned in a separate thread): in fact other things like Visibility and Readonly are also a problem when using the mm framework classes on my machine.

I've also uninstalled and reinstalled the framework without a change in the behavior.

Another thing that might be an issue is that I went from version 1.3 directly to 1.4.1 I uninstalled 1.3 and then ran the install for 1.4.1.

My next step is going to be trying to uninstall 1.4.1, install 1.4, see if that works, and then if that works, install 1.4.1. Maybe that will put me on the right path.

Thanks for your response Mike,

Rick
