I have been tearing my hair out trying to figure out how to get a grid to show grouped items on startup. That is, when the grid initiallly displays, it's automatically in group mode. The group panel is not visible, and the user cannot change the grid groupings.
No matter what I tried I couldn't make it work. Then, I noticed I had a line like:
myGrid.MasterGridView.AutoGenerateColumns = false;
If I remove this line -- voila, the startup mode of the grid is in group mode. It works as advertised.
Now, this is causing me other problems; namely, columns that I don't want to appear show up in the grid. So how can I get these two to happily coexist?
BTW, why can't you select AutoGenerateColumns in the designer? Seems to be missing.

Hello Jim,
Thank you for writing.
We do not have a known issue that anyhow changes the grouping behavior when columns are not auto-generated. I have tried a simple scenario like the described one and the grouping is working. You can find an example project as an attachment to this message.
Nevertheless, there could be something specific in your application that causes the issue. If you still experience it, please send me more details on your project or it will be better if you send me an example that demonstrates undesired behavior.
Concerning AutoGenerateColumns, it is only available at runtime because as soon as you choose DataSource in design-time the columns have been generated and technically, it is difficult to maintain AutoGenerateColumns property's functionality in the PropertyBuilder.
Do not hesitate to contact me again if you have other questions.
