CellEndEdit 后的 DataGridView SetFocus [英] DataGridView SetFocus after CellEndEdit

问题描述

我使用了 CellEndEdit 事件，在编辑单元格值后按 Enter 键，然后单元格焦点向下移动.

I used the CellEndEdit event, after editing the cell value I press the Enter Key, then the cell focus moves down.

我希望焦点回到我编辑值的原始单元格.

I want the focus to go back at the original Cell where I edited the value.

我用了很多方法，但都失败了.

I used many ways, but failed.

Private Sub DataGridVie1_CellEndEdit(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridVie1.CellEndEdit
   '...
   '....editing codes here...to input and validate values...
   '...
   '...
   '...before the End If of the procedure I put this values
   DataGridVie1.Rows(e.RowIndex).Cells(e.ColumnIndex).Selected = True
   DataGridVie1.CurrentCell = DataGridVie1.Rows(e.RowIndex).Cells(e.ColumnIndex)
   'DataGridVie1.BeginEdit(False) '''DID NOT apply this because it cause to edit again.
End If

我不知道在编辑后或按 ENTER 键后焦点回到被编辑的原始单元格时的真实代码.

I don't know the real code when after edit or after a ENTER KEY the focus is back in the original Cell that was edited.

因为每次我按回车键，它都会直接进入下一个单元格.

Because everytime I HIT the ENTER KEY, it directly go down to the next Cell.

将焦点重新定位回原始单元格编辑的代码是什么.

Whats the code to reposition the focus back to the original Cell edited.

我知道 EditingControlShowing 方法，但我不认为我也必须使用该方法来获得我想要的.

I know the EditingControlShowing method but I don't think I have to used that method to get what I wanted too.

推荐答案

试试这个:定义 3 个变量.一个用于记忆是否进行了编辑操作，另外两个用于存储最后编辑单元格的行和列索引:

Try this: define 3 variables. One to memorize if an edit operation has been made, the other 2 to store row and column indexes of the last edited cell:

Private flag_cell_edited As Boolean
Private currentRow As Integer
Private currentColumn As Integer

当编辑操作发生时，你存储编辑单元格的坐标并在 CellEndEdit 事件处理程序中设置你的标志为 true:

When an edit operation occurs you store coordinates of edited cell and set your flag to true inside CellEndEdit event handler:

Private Sub DataGridView1_CellEndEdit(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellEndEdit
    flag_cell_edited = True
    currentColumn = e.ColumnIndex
    currentRow = e.RowIndex
End Sub 

然后在 SelectionChanged 事件处理程序中使用 currentRow 将 DataGridView 的 CurrentCell 属性设置为最后编辑的单元格和 currentColumn 变量来撤消默认的单元格焦点更改:

Then in SelectionChanged event handler you set DataGridView's CurrentCell property to the last edited cell using currentRow and currentColumn variables to undo default cell focus change:

Private Sub DataGridView1_SelectionChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles DataGridView1.SelectionChanged
    If flag_cell_edited Then
        DataGridView1.CurrentCell = DataGridView1(currentColumn, currentRow)
        flag_cell_edited = False
    End If
End Sub
