Actually I am facing a problem regarding UltraWinGrid when It's in Card View, how can i restrict text length? I've tried to accomplish it by setting MaxLength property in Initialize Layout event of the grid but still it receives more characters then the limit specified and when cell is changed it displays a message box regarding characters that should be there in the column, but it should not allow the user to type more then the limit specified isn't it? and when the grid is in normal view it is working fine with  ColumnStyle.DoubleWithSpin.

I can't see why CardView would make any difference to MaxLength. My best guess is that the MaxLength on the column is getting reset or cleared somewhere in your code. Have you tried checking the property at run-time to see if it is still set to something?

The second thing is when the data is invalid in the column I've called the DataRow's SetColumnError method to set the error on that column by type casting e.g. (DataRowView)e.Cell.Row.ListObject).Row. but still it isn't showing any error notification on the column which is working fine if the grid is in normal view.

I don't think this will work in CardView mode, because the error icon shows up in the RowSelector and CardView has no RowSelectors. Unless maybe the error icons displays in the Card caption area. Have you set the band.CardSettings.CaptionField?
