SftTree/OCX 7.5 - ActiveX Tree Control

EditNavigate Method, SftTree Object

Positions cell editing on another cell.

Syntax

object

A SftTree object.

Key

A virtual key code. The key to be handled.

Note: Symbolic names are only available to applications written in C/C++, which use the #include directive to include WinUser.h, part of the Windows header files.

Shift

The state of the SHIFT, CONTROL and ALT keys (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.

Handled

Returns True if the key Key was handled by the EditNavigate method, otherwise False is returned.

Comments

The EditNavigate method positions cell editing on another cell.

The EditNavigate method implements default cell navigation for the virtual key codes Key and is called to handle navigation keys pressed during cell editing. These keys can be defined using the CellEditIntercept method. A key that is intercepted will generate the EditNavigating event so the application can handle the key by calling EditNavigate.

Examples

VB.NET

            Combo1.Visible = True
            Combo1.Focus()
            Combo1.DroppedDown = True
        End If
    End Sub

    Private Sub AxSftTree1_EditNavigating(ByVal sender As Object, ByVal e As AxSftTreeLib75._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 AxSftTreeLib75._DSftTreeEvents_EditValidateEvent) Handles AxSftTree1.EditValidate
        ' Validate the new cell contents
        Dim S As String
        If e.vData Is Text1 Then
            S = Text1.Text
