<h5 id="C1_Win_FlexGrid_C1FlexGridBase_RowValidating_remarks"><strong>Remarks</strong></h5>
<div class="markdown level0 remarks"><p>This event is analogous to the <a class="xref" href="https://learn.microsoft.com/dotnet/api/system.windows.forms.control.validating">Validating</a> event.</p>
<p>Use this event to perform validation on all the values of a row.
If the row does not pass validation, set the <a class="xref" href="C1.Win.FlexGrid.RowColEventArgs.Cancel.html#C1_Win_FlexGrid_RowColEventArgs_Cancel">Cancel</a> property to true.</p>
<p>Canceling this event prevents the <a class="xref" href="C1.Win.FlexGrid.C1FlexGridBase.RowValidated.html">RowValidated</a> event from occurring, 
and also prevents the user from leaving the invalid row.</p>
