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

作者：中国论坛网收集 来源： 加入时间：2004-8-25

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
End If
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)
end sub

'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.
