CustomExpandEventArgs.IsExpanded Property
Gets or sets whether the item is expanded.
Namespace: DevExpress.Xpf.PropertyGrid
Assembly: DevExpress.Xpf.PropertyGrid.v20.1.dll
NuGet Packages: DevExpress.WindowsDesktop.Wpf.PropertyGrid, DevExpress.Wpf.PropertyGrid
Declaration
Property Value
Type | Description |
---|---|
Boolean | true, if the item is expanded; otherwise, false. |
Remarks
Handle the PropertyGridControl.CustomExpand event to expand a row (or category). This event fires for each PropertyGridControl item. Set the event arguments’ IsExpanded property to true to expand a processed item.
When the IsExpanded property is set to true, end-users cannot collapse items in the PropertyGridControl. Set the IsExpanded property to true only if the processed item is initializing (CustomExpandEventArgs.IsInitializing is true) to allow end-users to collapse the control items.
The code sample below demonstrates how to expand all the items within the control and allow end-users to collapse them:
void PropertyGridControl_CustomExpand(object sender, CustomExpandEventArgs args) {
if(args.IsInitializing)
args.IsExpanded = true;
}
