Currently my model by inheriting from System.ComponentModel.IDataErrorInfo.
When we input the invalid data,we just can see the red border around the
SfTextBoxExt ,the error message cannot show up.So please provide a sample for my reference .

Xaml code is as below.

<syncfusion:SfTextBoxExt Grid.Row="5" x:Name="muliple"

Watermark="Enter tags seperated by comma" SearchItemPath="Name"

AutoCompleteSource="{Binding Items}"

AutoCompleteMode="Suggest" Delimeter=","

Text="{Binding UpdateSourceTrigger=PropertyChanged, Path=QueryModel.StringTags, ValidatesOnDataErrors=true, NotifyOnValidationError=true, Mode=TwoWay}"

WatermarkTemplate="{StaticResource WatermarkTemplate}"
