SftTree/OCX 8.0 - ActiveX Tree Control

EditNavigating Event, SftTree Object

A key has been intercepted which is used for navigation during cell editing.

Syntax

object

A SftTree object.

Key

A virtual key code. Defines the key that was intercepted. See the CellEditIntercept method for a list of available virtual key codes.

Shift

The state of the SHIFT, CONTROL and ALT keys during the event (see SftTreeKeyConstants). A bit is set if the key is down. The Shift argument is a bit field with bits corresponding to the SHIFT, CONTROL and ALT keys. The Shift variable indicates the state of these keys. Some, all, or none of the bits can be set, indicating which of the keys are pressed.

EditIndex

The zero-based index of the item being edited. The combination of EditIndex and EditCol describes an individual cell.

EditCol

The zero-based column number. The combination of EditIndex and EditCol describes an individual cell.

Comments

The EditNavigating event occurs when a key has been intercepted which is used for navigation during cell editing.

The CellEditIntercept method defines keystrokes to be intercepted during cell editing using the EditNavigating event. Only navigation keys should be intercepted. Other keys can be handled in the control's own event handlers (KeyDown/KeyPress/KeyUp events).

An application can handle a key by calling EndEdit to end cell editing of the current cell, followed by a call to Cell.Edit for the new cell to be edited.

Examples

VB.NET

            Combo1.Height = e.heightPix
            Combo1.Enabled = True
            Combo1.Visible = True
            Combo1.Focus()
            Combo1.DroppedDown = True
        End If
    End Sub

    Private Sub AxSftTree1_EditNavigating(ByVal sender As Object, ByVal e As AxSftTreeLib80._DSftTreeEvents_EditNavigatingEvent) Handles AxSftTree1.EditNavigating
        ' Process key pressed
        AxSftTree1.EditNavigate(e.key, e.shift)
    End Sub

    Private Sub AxSftTree1_EditValidate(ByVal sender As Object, ByVal e As AxSftTreeLib80._DSftTreeEvents_EditValidateEvent) Handles AxSftTree1.EditValidate
        ' Validate the new cell contents
        Dim S As String
