Property Value

Type Description

A Boolean value that specifies whether the item is being initialized.


When the CustomExpandEventArgs.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 (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) {
        args.IsExpanded = true;
