Hello,
I am trying to check some custom validation when a value is adjusted on a TelerikForm. And I am using
EditContext.OnFieldChanged += HandleFieldChanged;
But the value is still the old value, it looks like the TelerikInputBase is firing the notification before the change is actually applied.
private protected void TriggerChange(T value)
{
if (this.ValidateOn == ValidationEvent.Change)
this.CascadedEditContext?.NotifyFieldChanged(this.FieldIdentifier);
this.OnChange.InvokeAsync((object) value);
}Is there a better way to be doing this?
I do not want to have to add the validation check on every input OnChange.
I have also tried OnFormUpdate with the same issue, this is the function I am using where EditContext still has the old values
protected async Task OnFormUpdate(FormUpdateEventArgs args)
{
if (!IsUpdating)
{
IsUpdating = true;
DataHasChanged = true;
var type = args.Model.GetType();
var property = type.GetProperty(args.FieldName);
if (property != null)
{
if (property.GetCustomAttributes(typeof(SkipMessageCheckAttribute), true).FirstOrDefault() is not SkipMessageCheckAttribute)
{
await CheckMessagesAsync();
}
}
IsUpdating = false;
}
DataIsValid = !EditContext.GetValidationMessages().Any() && Messages.All(m => m.Priority != PageMessagePriority.Error);
}Thanks,
Matt
