MSHFlexGrid edit problem: textbox won't show

I'm working on a program, which included an "editable" grid (MSHFlexGrid). I borrowed code from a VB book, which told me to superimpose a textbox whenever I click a cell.

With MSHFlexgrid1
' Cancel range selection, if any.
.RowSel = .Row
.ColSel = .Col
' Move the cell editor into place by making it one pixel smaller
' than the current cell.
txtCellEditor.Move .Left + .CellLeft, .Top + .CellTop, _
.CellWidth - ScaleX(1, vbPixels, vbTwips), _
.CellHeight - ScaleY(1, vbPixels, vbTwips)
' Transfer the contents of the current cell into the TextBox.
txtCellEditor.Text = .Text
' Move the TextBox in front of the grid.
txtCellEditor.Visible = True
txtCellEditor.ZOrder
txtCellEditor.SetFocus
' Remember current coordinates for later.
cellRow = .Row
cellCol = .Col
End With

I really don't see any problem with the code. I just don't know why the textbox (txtCellEditor) won't show whenever I invoke the click button on the grid. More surprisingly, the data I enter in the textbox is entered into the grid after the textbox loses focus. Just wondering how to make that textbox appear and let the user see what he is editing.

Hope anyone can help. Thanks in advance!!!

I think your ZOrder line is incomplete

Instead of .. txtCellEditor.ZOrder
,, try this ... txtCellEditor.ZOrder 0

Thanks for responding, Spoo.

Unfortunately specifying the ZOrder didn't work out.

Can't really seem to figure out what's wrong here.

Think you can find out other causes for this? Thanks very much.

I didn't try your code, but I did try this code snippet.

Code:

---

Private Sub FG1_Click()
    '
    With FG1
        X1 = .CellLeft + .Left
        Y1 = .CellTop + .Top
        With Text1
            .Left = X1
            .Top = Y1
        End With
    End With
    '
End Sub

---

Note that I have added this as a Click event sub.
Change the name to match your FG's name

There was no apparent need for any ZOrder 0 statement.
The TextBox just snaps to the selected FG cell.

Hope that gives you something to start with.

Thanks for giving time on this, Spoo.

I think the box is snapping correctly to the cell (I traced its coordinates), and probably the reason for the X-Y trace was that the *box still doesn't pop up*. (Whew.)

I don't know if it's the grid or the box or me that's the problem. I'm starting to brand this as a hopeless case, though I hope not.

Does the MSHFlexGrid need any special property setups? Or the Textbox, for that matter? Thank you, or anyone who can answer this, in advance.

There must be something else going on as your original code works fine for me. Can you zip the entire Project up and post it here?

Doogle,

The grid in question is the flexSimulation MSHFlexGrid. I included everything thinking that there maybe something wrong with the project components or references as well.

I really hope you can help me out on this. I think it'll be just a little while before I pass out. Thanks a bunch.

Well, I can't run your full Project as I don't have the necssary OCX or correct Crystal Reports Active X components. I did the next best thing and copied the code from the Form (and a Sub from a Module) into a new project:

Code:

---

Option Explicit

Private cellrow As Long
Private cellcol As Long

Private Sub flexSimulation_Click()
  ShowCellEditor
End Sub

Private Sub flexSimulation_KeyPress(KeyAscii As Integer)
    If KeyAscii < 48 Or KeyAscii > 57 Then
        KeyAscii = 0
    Else
        ShowCellEditor
        txtCellEditor.Text = Chr$(KeyAscii)
        txtCellEditor.SelStart = 1
    End If
End Sub

Private Sub txtCellEditor_KeyPress(KeyAscii As Integer)
    If KeyAscii < 48 Or KeyAscii > 57 Then
        Select Case KeyAscii
            Case 8
                Exit Sub
            Case 13
                HideCellEditor
            Case 27
                HideCellEditor True ' Also cancel the edit.
            Case Else
                KeyAscii = 0
        End Select
    End If
End Sub

Private Sub txtCellEditor_LostFocus()
  HideCellEditor
End Sub

Private Sub ShowCellEditor()
    With flexSimulation
        ' Cancel range selection, if any.
        .RowSel = .Row
        .ColSel = .Col
        ' Move the cell editor into place by making it one pixel smaller
        ' than the current cell.
        txtCellEditor.Move .Left + .CellLeft, .Top + .CellTop, _
            .CellWidth - ScaleX(1, vbPixels, vbTwips), _
            .CellHeight - ScaleY(1, vbPixels, vbTwips)
        ' Transfer the contents of the current cell into the TextBox.
        txtCellEditor.Text = .Text
        ' Move the TextBox in front of the grid.
        txtCellEditor.Visible = True
        txtCellEditor.ZOrder 0
        txtCellEditor.SetFocus
        ' Remember current coordinates for later.
        cellrow = .Row
        cellcol = .Col
    End With
   
  With txtCellEditor
      Label1.Caption = .Top & ", " & .Left & ", " & .Width & ", " & .Height
  End With
   
  SelectTextboxText txtCellEditor
End Sub

Sub HideCellEditor(Optional Cancel As Boolean)
    ' Hide the TextBox control if necessary.
    If txtCellEditor.Visible Then
        ' If the operation hasn't been canceled, transfer the contents
        ' of the TextBox into the cell that was active.
        If Not Cancel Then
            flexSimulation.TextMatrix(cellrow, cellcol) = txtCellEditor.Text
        End If
        txtCellEditor.Visible = False
    End If
End Sub

Sub SelectTextboxText(pobjTextBox As TextBox)
    With pobjTextBox
        .SelStart = 0
        .SelLength = Len(.Text)
    End With
End Sub

and I can't replicate you problem at all ! The TextBox moves to the correct place, accepts only numbers as input, and adds the validated input to the correct cell in the Grid when Return is pressed and / or cancels the edit if ESC is pressed.

EDIT: Found the problem. Your Form is set to ScaleMode 3 - Pixel so when you're resizing the TextBox it's not where it should be and it's not as large as you think. Simplest solution is to set the Form's ScaleMode to 1 - Twip and change

Code:

---

        txtCellEditor.Move .Left + .CellLeft, .Top + .CellTop, _
            .CellWidth - ScaleX(1, vbPixels, vbTwips), _
            .CellHeight - ScaleY(1, vbPixels, vbTwips)

to

Code:

---

        txtCellEditor.Move .Left + .CellLeft, .Top + .CellTop, _
            .CellWidth - 1, _
            .CellHeight - 1

---

The TextBox then sits pretty comfortably over the required Cell.

Thank goodness you managed to stop by this post.

I really didn't know the science of scaling, and how it would affect the visibility of the textbox. It's, as you said, finally sitting comfortably. I guess I just need to tweak its position so it would match the coordinates of each cell being clicked.

Again, many many thanks. You've been a huge help! :)
