TabControl.TabPageCollection.IndexOfKey(String) Method

Definition

Returns the index of the first occurrence of the TabPage with the specified key.

public:
 virtual int IndexOfKey(System::String ^ key);
public virtual int IndexOfKey (string key);
public virtual int IndexOfKey (string? key);
abstract member IndexOfKey : string -> int
override this.IndexOfKey : string -> int
Public Overridable Function IndexOfKey (key As String) As Integer

Parameters

key
String

The name of the tab page to find in the collection.

Returns

The zero-based index of the first occurrence of a tab page with the specified key, if found; otherwise, -1.

Remarks

If IndexOfKey is called successively, the last returned index will be checked for a key match first, and if there is no match, the search starts at the beginning of the collection.

The Name property corresponds to the key for a TabPage in the TabControl.TabPageCollection. The key comparison is not case-sensitive. If the key parameter is null or an empty string, IndexOfKey returns -1.
