You dont need a converter for doing this. You can use the StringFormat
in binding itself to format your selected datetime to show just date in mm/dd/yyyy format.
<TextBlock Text="{Binding Date, StringFormat={}{0:MM/dd/yyyy}}" />
I tested with this code and it is working fine.
XAML:
<DataGrid AutoGenerateColumns="False" ItemsSource="{Binding TestList}">
<DataGrid.Columns>
<DataGridTemplateColumn Header="Start">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<TextBlock Text="{Binding Start, StringFormat=d}" FontFamily="Verdana" />
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
<DataGridTemplateColumn.CellEditingTemplate>
<DataTemplate>
<DatePicker SelectedDate="{Binding Start}" FontFamily="Verdana" >
<DatePicker.CalendarStyle>
<Style TargetType="Calendar">
<Setter Property="DisplayMode" Value="Month"/>
</Style>
</DatePicker.CalendarStyle>
</DatePicker>
</DataTemplate>
</DataGridTemplateColumn.CellEditingTemplate>
</DataGridTemplateColumn>
</DataGrid.Columns>
</DataGrid>
Model:
public class TestData
{
DateTime start;
public DateTime Start
{
get { return start; }
set { start = value; }
}
}
ViewModel has list of TestData to be bound to DataGrid:
public List<TestData> TestList { get; set; }
