How to validate datarow

[Frank Lin]

Hi,all
Syncfusion has provided an interesting control,espeicially its Datagrid. I''m now testing it.
Could it validate a datarow before the cursor jumps to the next/new line? If the validation fails, the cursor should stay where it was. I know how to validate a datacolumn. But if the user inputs some fields in a new datarow and avoid others fields in this row. Not all the fields'' datacolumn Changing event will triger. So it''s unacceptalbe to validate a row by validating all the fields in the row.
thx.

You can subscribe to the RowLeave event . There do your row level validation. If it fails, set e.Cancel = true.

I need to do validation of new records but only in the GridGroupingControl. Which events can I use to cancel addition of a the record if it fails validation.

Hi Vlad,

You can make use of the following 2 events .
1) CurrentRecordContextChange
2) CurrentCellValidating

But I would prefer "CurrentRecordContextChange" as it has more options and it can also stop from moving the current record, if it finds invalid data.

In the sample attached, I implemented the both and commented the one at a time.
