Right Mike, something is wrong. I need to check whether this property is re-set somewhere.

Sorry for my ignorance, but what do you mean with "loading a layout"?

 Hi,

    If you set set SelectTypeCol to None and clicking the column header still selects the entire column, then something is wrong. There are no other properties that would override this setting. Either you are re-setting this property in code or else your code is doing something else that is causing the behavior. Maybe you are loading a layout? 

Thank you all for your assistance!

 Well... right now I am at home and don't have the source code available. But I am sure I've set the properties according to what was described above. 

Any other properties which could disturb the desired behavior?

 Have a nice day!

 Setting SelectTypeCol to None (as the sample code above shows) should prevent the column from being selected.

Hi!

I mean that the entire column is selected/highlighted. The column header isn't highlighted at all, just the column underneath.
