ComboBox::FindString Method (String^)
Returns the index of the first item in the ComboBox that starts with the specified string.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
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 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 method that provides a parameter for specifying a starting index within the ComboBox. If you want to perform a search for an exact word match instead of a partial match, use the FindStringExact method.
