增加 MsFlexGrid 的编辑功能

（作者：佚名加载日期: 2002/3/31）

概述

MsFlexGrid 控件没有提供文本编辑的功能，下面的例子演示了如何利用一个TextBox 实现编辑当前网格的功能

。

在按下一个键后，就把TextBox 移动到当前的位置，并激活。在键入回车或移动到其他网格时，

就把TextBox 中的内容放到网格中。

实现步骤

1 打开 VB5，开启一个新的工程。

2 在菜单“工程”中选择“部件”，在列表中选中“Microsoft FlexGrid Control ..”

3 放一个 MsFlexGrid 控件和一个TextBox 控件(Text1)到 Form1。修改MsFlexGrid 控件的名称为 Grid1，

设置Grid1 的行，列为 4，固定行，列为 0。设置 Text1 的 Visiable 为 False，BorderStyle 为

None(0)。

4 在Form1 的代码中增加声明：

Const ASC_ENTER = 13 '回车

Dim gRow As Integer

Dim gCol As Integer

5 增加代码到 Grid_KeyPress 过程：

Private Sub Grid1_KeyPress(KeyAscii As Integer)

' Move the text box to the current grid cell:

Text1.Top = Grid1.CellTop + Grid1.Top

Text1.Left = Grid1.CellLeft + Grid1.Left

' Save the position of the grids Row and Col for later:

gRow = Grid1.Row

gCol = Grid1.Col

' Make text box same size as current grid cell:

Text1.Width = Grid1.CellWidth - 2 * Screen.TwipsPerPixelX

Text1.Height = Grid1.CellHeight - 2 * Screen.TwipsPerPixelY

' Transfer the grid cell text:

Text1.Text = Grid1.Text

' Show the text box:

Text1.Visible = True

Text1.ZOrder 0 ' 把 Text1 放到最前面！

Text1.SetFocus

' Redirect this KeyPress event to the text box:

If KeyAscii <> ASC_ENTER Then

SendKeys Chr$(KeyAscii)

End If

End Sub

6 增加代码到 Text1_KeyPress 过程：

Private Sub Text1_KeyPress(KeyAscii As Integer)

If KeyAscii = ASC_ENTER Then

Grid1.SetFocus ' Set focus back to grid, see Text_LostFocus.

KeyAscii = 0 ' Ignore this KeyPress.

End If

End Sub

7 增加代码到 Text1_LostFocus 过程：

Private Sub Text1_LostFocus()

Dim tmpRow As Integer

Dim tmpCol As Integer

' Save current settings of Grid Row and col. This is needed only if

' the focus is set somewhere else in the Grid.

tmpRow = Grid1.Row

tmpCol = Grid1.Col

' Set Row and Col back to what they were before Text1_LostFocus:

Grid1.Row = gRow

Grid1.Col = gCol

Grid1.Text = Text1.Text ' Transfer text back to grid.

Text1.SelStart = 0 ' Return caret to beginning.

Text1.Visible = False ' Disable text box.

' Return row and Col contents:

Grid1.Row = tmpRow

Grid1.Col = tmpCol

End Sub

8 好了。按 F5 开始测试。您可以自由地在 Grid 中移动，按回车可以开始或结束编辑。使用MsFlexGrid控件的几个函数

在VB处理数据显示的时候,使用表格是一种好的方法,虽然DataGrid可以与数据源绑定,但是总有美中不足,就是

外观不好看,所以有时应用MsFlexGrid显示数据还是一种比较好的方法,以下几个函数是用来控制MsFlexGrid的

程序

(本人语言表达能力有限,还请见谅)

''MsFlexGrid操作函数

''合并列

Public Function MergeCol(GridObj As Object, ByVal StartCol As Long, ByVal EndCol As Long, ByVal

ColValue As String, ByVal CurrentRow As Long) As Boolean

If StartCol > EndCol Or StartCol > GridObj.Cols Or CurrentRow > GridObj.Rows Then MsgBox "对不起，行列设置错误！", vbOKOnly, App.Title

MergeCol = False

Exit Function

End If

For I = StartCol To EndCol

GridObj.MergeCol(I) = True

GridObj.TextArray(faIndex(GridObj, CurrentRow, I)) = ColValue

GridObj.ColAlignment(I) = flexAlignCenterCenter

Next I

GridObj.MergeRow(CurrentRow) = True

MergeCol = True

End Function

''合并行

Public Function MergeRow(GridObj As Object, ByVal StartRow As Long, ByVal EndRow As

Long, ByVal

RowValue As String, ByVal CurrentCol As Long) As Boolean

If StartRow > EndRow Or StartRow > GridObj.Rows Or CurrentCol > GridObj.Cols Then MsgBox "对不起，行列设置错误！", vbOKOnly, App.Title

MergeRow = False

Exit Function

End If

For I = StartRow To EndRow

GridObj.MergeRow(I) = True

GridObj.TextArray(faIndex(GridObj, I, CurrentCol)) = RowValue

GridObj.ColAlignment(CurrentCol) = flexAlignCenterCenter

Next I

GridObj.MergeCol(CurrentCol) = True

MergeRow = True

End Function

''转换索引

Public Function faIndex(GridObj As Object, ByVal row As Integer, ByVal col As Integer) As Long

If row > GridObj.Rows Or row < 0 Or col > GridObj.Cols Or col < 0 Then

MsgBox "对不起，行列设置错误！", vbOKOnly, App.Title

faIndex = -1

Exit Function

End If

faIndex = row * GridObj.Cols + col

End Function

''插入行

Public Function SetItem(GridObj As Object, ByVal row As Integer, ByVal col As Integer, ByVal

SetValue As String) As Boolean

If row > GridObj.Rows Or row < 0 Or col > GridObj.Cols Or col < 0 Then

MsgBox "对不起，行列设置错误！", vbOKOnly, App.Title

SetItem = False

Exit Function

GridObj.TextArray(faIndex(GridObj, row, col)) = SetValue

SetItem = True

End Function

''得到单元格值

Public Function GetItem(GridObj As Object, ByVal row As Integer, ByVal col As Integer) As String

If row > GridObj.Rows Or row < 0 Or col > GridObj.Cols Or col < 0 Then

MsgBox "对不起，行列设置错误！", vbOKOnly, App.Title

GetItem = ""

Exit Function

End If

GetItem = GridObj.TextArray(faIndex(GridObj, row, col))

End Function

在msflexgrid控件中每一个cell格的内容是不可以由用户直接编辑的但是我们可以通过一些小技

巧来方便的实现这编辑功能来扩展msflexgrid的应用（在实际应用中这是很常用的功能）。

你只需按下面的做即可轻松实现编辑msflexgrid控件数据的功能

例在窗体上放一文本框txtvalue，和一msflexgrid控件grid

‘文本框控件的keypress事件

private sub txtvalue_keypress(keyascii as integer)

‘放入一些处理过程，如只需输入数字时的处理

dim i

i=1

end sub

private sub txtvalue_change()

grid.text = txtvalue.text

end sub

'在grid的entercell事件中加入下例代码

private sub grid_entercell()

txtvalue.text = grid.text

txtvalue.selstart = 0

txtvalue.sellength = len(txtvalue.text)

'当用户输入数据时直接调用文本框的keypress事件

private sub grid_keypress(keyascii as integer)

txtvalue_keypress keyascii

end sub

ok,这样一个可编辑的msflexgrid控件就完成了，简单吧!!

原理

当用户点击msflexgrid中的某个cell格要输入数据时,产生entercell事件，在这里我们对文本

框进行初始化，输入当前cell格中的内容，并且选中所有文本。当用户要按下按键进行输入时，就直

接调用txtvalue的事件，由文本框来处理.
