Since validateRow() returns synchronously, there is no way for it to tell you the result of a remote validation, which is asynchronous. However, you can find out if a field has errors with fieldHasErrors(), and you can find out that a validation response has just come back from the server by installing a transformResponse() handler on the DataSource.

I thought it was due to an asynchronous call. Thanks for the hint of how to get to the answer from the server.

I think I've found a mistake.

When ListGrid.setShowRowNumbers (true);
an attempt to connect ValuesManager to the ListGrid,

ValuesManager vm = new ValuesManager ();
[B]listGrid_Wyniki.setValuesManager (vm)[/B];

causes an error in the browser console:
TypeError: fieldName.contains is not a function.

When ListGrid.setShowRowNumbers (false) then there is no error.
I need to display the numbers of the lines in ListGrid.

The browser debugger indicates an execution error in ISC_Core.js (line: 90995):
var isDataPath = fieldName.contains (separator);

Tested on SmartGwt 6.1p from 27/05/2019


Additional info
I have been looking further and probably more reason is change in ListGrid some value, and then manually call ListGrid.saveAllEdits () function.
I am reminded that my current ListGrid and DataSource configuration is set in ClienetOnly (true) and SaveLocaly (true) with remote validation, so I use setEditValues (.., ..) to start remote validation. If I do not execute saveAllEdits (), this error does not appear, but I see all the time that the records have been modified (a different font color indicating that the cell has been edited), despite the fact that they passed the validation

A ValuesManager aggregates forms. What were you hoping would happen here?

[ciopers]

I wanted to connect ValuesManager to ListGrida to find out if the column contains errors as a result of remote validation. I can not do it this way?

We already explained how to do this in post #16 in this thread, and it does not involve a ValuesManager, and again, it does not make sense to use a ValuesManager with a ListGrid.
