DataForm allows you to use a specific editor type such as built-in supported editor or a custom editor generically to the properties of DataObject that have similar data types. This article explains how to register a built-in editor or custom editor to the same data type in business object. Here, DayHours is data model for dataform. public class DayHours : INotifyPropertyChanged
{
private int startHour;
private int startMinutes;
[Display(Name = "Start Hour")]
public int StartHour
{
get
{
return startHour;
}
set
{
startHour = value;
RaisePropertyChanged("StartHour");
}
}
public int StartMinutes
{
get
{
return startMinutes;
}
set
{
startMinutes = value;
RaisePropertyChanged("StartMinutes");
}
}
public event PropertyChangedEventHandler PropertyChanged;
private void RaisePropertyChanged(String Name)
{
if (PropertyChanged != null)
this.PropertyChanged(this, new PropertyChangedEventArgs(Name));
}
}
In the following code snippet, the “NumericUpDown” editor type has been registered generically to all int data type properties in underlying DataObject using the RegisterEditor method. dataForm.DataObject = new DayHours(); dataForm.RegisterEditor(typeof(int), "NumericUpDown");
By doing this, you can avoid registering the editor type to every property in business object that needs same editor type. dataForm.RegisterEditor("StartHour", "NumericUpDown");
dataForm.RegisterEditor("StartMinutes", "NumericUpDown");
Sample Demo: RegisterCommonEditor You can register custom editor generically to the properties that have same data type. Here, a customer editor named as CustomSlider that have Slider as Editorview has been given. You can use this custom editor for the properties that have int data type.
public class CustomSliderEditor : DataFormEditor<Slider>
{
public CustomSliderEditor(SfDataForm dataForm) : base(dataForm)
{
}
protected override Slider OnCreateEditorView(DataFormItem dataFormItem)
{
return new Slider();
}
protected override void OnInitializeView(DataFormItem dataFormItem, Slider view)
{
base.OnInitializeView(dataFormItem, view);
view.Value = 15;
view.Minimum = 0;
view.Maximum = 23;
view.MaximumTrackColor = Color.Gray;
view.MinimumTrackColor = Color.HotPink;
view.ThumbColor = Color.HotPink;
}
}
Refer to the following code example for binding DataObject and adding CustomSliderEditor as CustomEditor using the RegisterEditor method dataForm.DataObject = new DayHours();
dataForm.RegisterEditor("Slider", new CustomSliderEditor(dataForm));
dataForm.RegisterEditor(typeof(int), "Slider");
