SyntaxThe PropertyCell type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | PropertyCell |
Initializes a new instance of the property cell
|
Properties| Name | Description | |
|---|---|---|
 | TypeBinding |
Gets or sets the binding to get the type for the
|
| Types |
Gets the list of types to use for each cell, in order of preference.
|
Methods| Name | Description | |
|---|---|---|
 | OnConfigureCell |
Configures an existing cell when it is reused for a different row or the data changes.
(Overrides CustomCell.OnConfigureCell(CellEventArgs, Control).) |
| OnCreateCell |
Creates an instance of the control for a cell.
(Overrides CustomCell.OnCreateCell(CellEventArgs).) |
| OnGetIdentifier |
Gets the identifier of the cell based on its content.
(Overrides CustomCell.OnGetIdentifier(CellEventArgs).) |
| OnPaint |
Raises the OnPaint(CellPaintEventArgs) event.
(Overrides CustomCell.OnPaint(CellPaintEventArgs).) |
Remarks
This is ideal for things like showing a property grid to edit various properties of an object.
The way this works is by using the TypeBinding of each row to determine which PropertyCellType
to use from the Types collection. It calls CanDisplay(Object) on each to find
a type that can display based on the value returned.
Each PropertyCellType added to the cell must have a unique value for Identifier
to ensure the correct control is shown in the cell. The identifier is used to cache the content controls generated by the
PropertyCellType when displaying the same value for other rows while scrolling.
Ideally, the content control generated from the PropertyCellType should use MVVM BindDataContext() methods
for its children so that they are updated automatically when reused for different controls. This is not a requirement, however
you must then implement/override the OnConfigure(CellEventArgs, Control) to update your control when the item/row is changed.
