IFileDialogControlEvents::OnItemSelected method (shobjidl.h)

Article
02/22/2024

Called when an item is selected in a combo box, when a user clicks an option button (also known as a radio button), or an item is chosen from the Tools menu.

Syntax

HRESULT OnItemSelected(
  [in] IFileDialogCustomize *pfdc,
  [in] DWORD                dwIDCtl,
  [in] DWORD                dwIDItem
);

Parameters

[in] pfdc

Type: IFileDialogCustomize*

A pointer to the interface through which the application added controls to the dialog.

[in] dwIDCtl

Type: DWORD

The ID of the control in which the user made a selection.

[in] dwIDItem

Type: DWORD

The ID of the selection.

Return value

Type: HRESULT

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

This notification is not sent when the user chooses an item from the drop-down menu attached to the Open button, because the action taken in that case is always the same: close the dialog as if the user had simply clicked the Open button. For that situation, the application can call GetSelectedControlItem to obtain the item the user chose from that menu.
