Properties

BindingTarget

Gets or sets the Dependency property of the editor element of the GridViewBoundColumnBase which actually is used for Binding to data source property.

Declaration
protected DependencyProperty BindingTarget { get; set; }
Property Value
System.Windows.DependencyProperty

The binding target.

DataFormatString

Gets or sets the data format string. Used with string.Format statement. This is a dependency property.

Declaration
public string DataFormatString { get; set; }
Property Value
System.String

The data format string.
Implements

DataMemberBinding

Gets or sets the binding which points to the data member to display in the cells of the GridViewBoundColumnBase.

Declaration
public virtual Binding DataMemberBinding { get; set; }
Property Value
System.Windows.Data.Binding

The display member binding.
Implements

DataType

Gets or sets the data type of the column. This usually reflects the type of the member that this column is bound to. This is a dependency property.

Declaration
public virtual Type DataType { get; set; }
Property Value
System.Type

The type for this bound column.
Implements

EditorStyle

Gets or sets the style which will be applied on the editor.

Declaration
public Style EditorStyle { get; set; }
Property Value
System.Windows.Style

The editor style.

ExportedElementWidth

Gets the actual width of the column.

Declaration
public double ExportedElementWidth { get; }
Property Value
System.Double

Implements

FilteringDisplayFunc

Gets the filtering display function.

Declaration
protected override Func<object, object> FilteringDisplayFunc { get; }
Property Value
System.Func<System.Object, System.Object>

The filtering display function.
Overrides
Remarks

This function is used by the filtering control distinct values list. It accepts a raw data value and returns what will become the content of the distinct value checkbox.

Header

Gets or sets the content of the column header.

Declaration
public override object Header { get; set; }
Property Value
System.Object

Overrides
Remarks

The ElementName binding does not work when used in column Header or CellTemplate. The problem comes from the fact that binding engine uses FindName method on FrameworkElement to find the target just once. So when element is loaded with LoadContent() – the element is not yet in the visual tree and FindName fails. As a solution, you can apply a Style to set the ContentTemplate.

IsReadOnlyBinding

Property that allows you to set individual columns into a readonly state using Binding.

Declaration
public Binding IsReadOnlyBinding { get; set; }
Property Value
System.Windows.Data.Binding

ValidatesOnDataErrors

Denotes in which mode GridViewBoundColumnBase will perform data validation.

Declaration
public GridViewValidationMode ValidatesOnDataErrors { get; set; }
Property Value
GridViewValidationMode

The default value is a combination between all modes (InViewMode and InEditMode).
