  • Reference

Definition

Namespace:
System.Windows.Forms
Assembly:
System.Windows.Forms.dll

Finds the first item in the ToolStripComboBox that starts with the specified string.

Overloads

FindString(String)

Finds the first item in the ToolStripComboBox that starts with the specified string.
FindString(String, Int32)

Finds the first item after the given index which starts with the given string.

FindString(String)

Finds the first item in the ToolStripComboBox that starts with the specified string.

public:
 int FindString(System::String ^ s);
public int FindString (string s);
public int FindString (string? s);
member this.FindString : string -> int
Public Function FindString (s As String) As Integer

Parameters

s
String

The String to search for.

Returns

Int32

The zero-based index of the first item found; returns -1 if no match is found.

Remarks

The search performed by this method is not case-sensitive. The s parameter is a substring to compare against the text associated with the items in the combo box list. The search performs a partial match starting from the beginning of the text, and returning the first item in the list that matches the specified substring. You can then perform tasks, such as removing the item that contains the search text or changing the item's text. Once you have found the specified text, if you want to search for other instances of the text in the ToolStripComboBox, use FindString method to specify a starting index within the ToolStripComboBox. If you want to perform a search for an exact word match instead of a partial match, use the FindStringExact method.

Applies to
