Methods

InsertItem(Int32, U)

Inserts an element into the System.Collections.ObjectModel.Collection at the specified index.

Declaration
protected override void InsertItem(int index, U item)
Parameters
Type Name Description
System.Int32 index

The zero-based index at which item should be inserted.
U item

The object to insert. The value can be null for reference types.
Overrides
Syncfusion.Windows.Forms.Tools.Navigation.ObservableCollectionBase<U>.InsertItem(System.Int32, U)
Exceptions
Type Condition
System.ArgumentOutOfRangeException

index is less than zero.-or-index is greater than System.Collections.ObjectModel.Collection.Count.

RemoveItem(Int32)

Removes the element at the specified index of the System.Collections.ObjectModel.Collection.

Declaration
protected override void RemoveItem(int index)
Parameters
Type Name Description
System.Int32 index

The zero-based index of the element to remove.
Overrides

Declaration
protected override void SetItem(int index, U item)
Parameters
Type Name Description
System.Int32 index

The zero-based index of the element to replace.
U item

The new value for the element at the specified index. The value can be null for reference types.
Overrides
