GridView.ValidationSummary.HasErrors?

[Mark]

Is there not a highlevel property that indicates if the condition of the grid has validation errors similar to

GridView.ValidationSummary.HasErrors?

Or is it necessary to do some type of iteration row by row?

Thanks.

Hi Mark,

Basically, you may handle the CellValidating/CellValidated/RowValidating or RowValidated events of the grid to verify whether there are any errors. Still, you may run through our online documentation for additional reference on the possible ways for handling the validation in RadGridView.

Hi Maya,

Thank you for confirming that there is no such indication on the grid.  This really would be something useful to have instead of needing to drill down to a row or cell.  Again it isn't a question of "how to" handle the events or validation, it is a status of the grid from higher abstraction.

The documentation doesn't have any reference to such in respect to the grid.

Hello Mark,

RadGridView does take care of the validation, but only for the items in the view port. Consequently, it is not appropriate to have a general abstract property defining the presence of all validation errors. 
However, depending on your particular scenario, you may implement a couple of possible approaches. 
Firstly, you may implement INotifyDataErrorInfo/ IDataErorInfo Interfaces that will ensure asynchronous data validation. Afterwards, as you are the one to know when a particular item has failed validation, you may set the appropriate style for the corresponding row.
Yet another approach would be to call the ScrollIntoView()/ScrollIntoViewAsync() method, once an invalid item comes. However, in this case you may result in scrolling up and down a bunch of times depending on the number and place of the invalid items. 
  

All the best,
