ComboBox.FindStringExact Method (String)

Finds the first item in the combo box that matches the specified string.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

public int FindStringExact (
	string s
)
public int FindStringExact (
	String s
)
public function FindStringExact (
	s : String
) : int
Not applicable.

Parameters

s

The String to search for.

Return Value

The zero-based index of the first item found; returns -1 if no match is found, or 0 if the s parameter specifies Empty.

The search performed by this method is not case-sensitive. The s parameter is a string to compare against the text associated with the items in the combo box list. The search looks for a match starting from the beginning of the text, 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 using the Remove method 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 ComboBox, you must use the version of the FindStringExact method that provides a parameter for specifying a starting index within the ComboBox. If you want to perform partial word search instead of an exact word match, use the FindString method.

The following code example demonstrates how to initialize a ComboBox control by setting the MaxDropDownItems and DropDownStyle properties and using the FindStringExact methods to search the ComboBox. It also shows handling the SelectedIndexChanged event.
