Properties

CellEditTemplate

Gets or sets the template of the cells in this column when in Edit mode. If this template is not set, editing is not allowed in the corresponding column. This is a dependency property.

Declaration
public DataTemplate CellEditTemplate { get; set; }
Property Value
System.Windows.DataTemplate

Remarks

The DataContext of this template is the event in the given row.

CellHighlightTemplate

Gets or sets the template of the cells in this column when the mouse is over the cell. If this property is not set, the value of the CellTemplate is used. This is a dependency property.

Declaration
public DataTemplate CellHighlightTemplate { get; set; }
Property Value
System.Windows.DataTemplate

Remarks

Please notice that the DataContext of this template is not actually the event in the given row, but a Proxy object containing the following properties: Start, End, Title, FormattedValue, OriginalEvent. The OriginalEvent is the event in the row and the FormattedValue is the value extracted through the MemberBinding.

CellSelectionTemplate

Gets or sets the template of the cells in this column when the mouse is over the cell. If this property is not set, the value of the CellTemplate is used.

Declaration
public DataTemplate CellSelectionTemplate { get; set; }
Property Value
System.Windows.DataTemplate

Remarks

Please notice that the DataContext of this template is not actually the event in the given row, but a Proxy object containing the following properties: Start, End, Title, FormattedValue, OriginalEvent. The OriginalEvent is the event in the row and the FormattedValue is the value extracted through the MemberBinding.

CellTemplate

Gets or sets the template of the cells in this column when in normal state. If the CellHighlightTemplate or CellSelectionTemplate are not set, the selected or highlighted cells also use this template. This is a dependency property.

Declaration
public DataTemplate CellTemplate { get; set; }
Property Value
System.Windows.DataTemplate

Remarks

When this template is set the GanttView's rendering is slower than using directly the MemberBinding property, so consider carefully if you need to use this property or not. Please notice that the DataContext of this template is not actually the event in the given row, but a Proxy object containing the following properties: Start, End, Title, FormattedValue, OriginalEvent. The OriginalEvent is the event in the row and the FormattedValue is the value extracted through the MemberBinding. Use FormattedValue for best performance.

IsResizable

Gets or sets a value indicating whether the column can be resized through the column resizer or not.

Declaration
public bool IsResizable { get; set; }
Property Value
System.Boolean

MaxWidth

Gets or sets the maximum width of the column. The value of this property doesn't restrict the ColumnWidth property.

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

MemberBinding

Gets or sets the binding to be used to evaluate the Cell content.

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

MinWidth

Gets or sets the minimum width of the column. The value of this property doesn't restrict the ColumnWidth property.

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

Methods

CreateInstanceOverride()

Declaration
protected override PlatformIndependentFreezable CreateInstanceOverride()
Returns
PlatformIndependentFreezable

Overrides

GetDataContextForItemOverride(Object)

When overridden in the derived class this method determines which is the actual data item for the row for a given item from the list (in most cases an HierarchicalItem).

Declaration
protected virtual object GetDataContextForItemOverride(object itemData)
Parameters
System.Object itemData

The original item from the source collection. In most cases this is an HierarchicalItem.
Returns
System.Object

The item to be used as a data item for the cell, generated for this column for the given data item. The default implementation just extracts the SourceItem from the HierarchicalItem.
