How to set a blank value to a picker editor in .NET MAUI DataForm?
In the Syncfusion® .NET MAUI DataForm (SfDataForm), you can set a blank value in a picker editor by utilizing custom data binding and source provisioning. Here's how you can achieve that with a simple example.
C#
Use the RegisterEditor method to associate the Picker Editor with specific properties in your form.
protected override void OnAttachedTo(ContentPage bindable)
{
base.OnAttachedTo(bindable);
this.dataForm = bindable.FindByName<SfDataForm>("dataForm");
if (this.dataForm != null)
{
this.dataForm.ColumnCount = 2;
this.dataForm.ItemsSourceProvider = new ItemSourceProvider();
this.dataForm.RegisterEditor("From", DataFormEditorType.Picker);
this.dataForm.RegisterEditor("To", DataFormEditorType.Picker);
this.dataForm.RegisterEditor("PaymentMethod", DataFormEditorType.ComboBox);
}
}
C#
Create a class that implements IDataFormSourceProvider, to supply data to the Picker editors, including a blank option.
class ItemSourceProvider : IDataFormSourceProvider
{
public object GetSource(string sourceName)
{
if (sourceName == "From")
{
List<string> cityFrom = new List<string>() { " ", "Boston", "Los Vegas", "Chicago", "Portland" };
return cityFrom;
}
if (sourceName == "To")
{
List<string> cityTo = new List<string>() { " ", "Los Angeles", "Seattle", "New York", "Denver" };
return cityTo;
}
return new List<string>();
}
}
