Hi
I am using IDataErrorInfo for managing error in object, I can generate error in some cases in child row, but it doesn;t show error icon in parent row, when all grid are collapsed no one can notice error in child grid, I want to show error in parent row at same time, I need some idea, help me with code example.

modified: if I make RowAndCell then it will through icon on every cell of parent row, when I got error on child row.
Thanks Hristo, But what happen if there is any data validation error on parent table , it shouldn't show icon on parent relative cell , if I make RowAndCell then it will through icon on every cell of parent row, so there is not any way to set error icon on rowselector and relative cell both parent and child level.
Hello ,
You could apply SupportDataErrorInfo by band level, so on your second band you could apply this property to CellOnly for example and also you should implement validate method, which validates all of your fields and for the Attendence class. Please see attached sample.
Please let me know if you have any further questions.
In this case, I could n't show any error icon on any cell but only on row selector, what I will do, if will have to show icon on relative cell as well as row selector.
thanks
it is really helpful, but in different scenairio, what should I do if I have to show error in row level as well current error cell.
in parent as well as child band.
