though I need the height to be set to "auto" I've tried it but it didnt worked out well.

 thanks for the suggestion

I was hurt the same problem.

Probably, that is bug of xamDataGrid.

Do not set XamDataGrid`s height = "auto" .

Sepcify height for number

Height ="300"

Hi,

I'm not sure why that happens.  Sorry, I don't have a solution for that one. If you send our Developer Support team a sample that reproduces the behavior, they can have you notified when the issue is resolved.

Thanks,

Josh

well, its working, but...

when I have many rows on the subsequent grid which I just opened by pressing the expand indicator,

then apeared 2 scroll bars - one to the right and one to the left.

if I disable the left scrollbar (which belongs to the grid) then I scroll down to the bottom of the scrollbar but

I dont get to see all the rows, - its like not all the grid is visible on the scrollviewer though i use the verticalalignment="stretch"
