Hi,

I can suggest you to show the sibling bands on the first level as shown in the uploaded sample.

Let me know if this works for you.

Best Regards,

Thanks Stefaniya,

That is basically what I did.

In addition to hiding root band columns, I also remove child band identation and set root band row height to 1 pixel.

e.Layout.Bands[0].Indentation = -2;
e.Layout.Bands[0].Override.MinRowHeight = 1;
e.Layout.Bands[0].Override.DefaultRowHeight = 1;
e.Layout.Bands[1].Indentation = 0;
e.Layout.Bands[2].Indentation = 0;

The illusion is perfect :-)
