Event Data

The ColumnHeaderClick event's data class is ColumnHeaderClickEventArgs. The following properties provide information specific to this event:

Property	Description
AllowSorting	Gets or sets whether it is allowed to sort by the column’s values.
Column	Gets a column whose header is clicked.
Handled	Gets or sets a value that indicates the present state of the event handling for a routed event as it travels the route. Inherited from RoutedEventArgs.
IsCtrl	Gets or sets whether the Ctrl key is pressed.
IsShift	Gets whether the Shift key is pressed.
OriginalSource	Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class. Inherited from RoutedEventArgs.
RoutedEvent	Gets or sets the RoutedEvent associated with this RoutedEventArgs instance. Inherited from RoutedEventArgs.
Source	Gets or sets a reference to the object that raised the event. Inherited from RoutedEventArgs.

The event data class exposes the following methods:

Method	Description
InvokeEventHandler(Delegate, Object)	When overridden in a derived class, provides a way to invoke event handlers in a type-specific way, which can increase efficiency over the base implementation. Inherited from RoutedEventArgs.
OnSetSource(Object)	When overridden in a derived class, provides a notification callback entry point whenever the value of the Source property of an instance changes. Inherited from RoutedEventArgs.

Remarks

If column sorting is enabled, the GridControl raises the ColumnHeaderClick event when a user clicks a column header.

Use the following code snippet to ensure data is not sorted when a user clicks a column header:

C#

void TableView_ColumnHeaderClick(object sender, DevExpress.Xpf.Grid.ColumnHeaderClickEventArgs e) {
    e.Handled = true;
}

VB.NET

Private Sub TableView_ColumnHeaderClick(ByVal sender As Object, ByVal e As DevExpress.Xpf.Grid.ColumnHeaderClickEventArgs)
    e.Handled = True
End Sub
