这里是关键事件的代码

Hello Friends

I have a query related to focus on cell in datagridview.

Acutally i have a datagridview and i want to move from cell 1 to cell 2 on keydown event and also check if the cell 1 is not blank then it moves to cell 2 otherwise move to cell 3.

My code works fine for column but it moves to next row.

here is my code on key down event

If e.KeyCode = Keys.Enter Then
            Select Case DataGridView1.CurrentCell.ColumnIndex
                Case 1
                    If Len(Trim(DataGridView1.CurrentRow.Cells(1).Value)) > 0 Then
                        DataGridView1.CurrentCell = DataGridView1(2, DataGridView1.CurrentCell.RowIndex)
                        DataGridView1.Focus()
                    Else
                        DataGridView1.CurrentCell = DataGridView1(3, DataGridView1.CurrentCell.RowIndex)
                    End If
                Case 2
                    DataGridView1.CurrentCell = DataGridView1(3, DataGridView1.CurrentCell.RowIndex)
                Case 3
                    DataGridView1.CurrentCell = DataGridView1(4, DataGridView1.CurrentCell.RowIndex)
                Case 4
                    DataGridView1.CurrentCell = DataGridView1(5, DataGridView1.CurrentCell.RowIndex)
                Case 5
                    DataGridView1.CurrentCell = DataGridView1(1, DataGridView1.CurrentCell.RowIndex + 1)
            End Select
        End If

它有效但转到下一行。

推荐答案

它将移动到下一行，因为这是ENTER键通常所做的。你需要告诉它你自己处理它，它应该跳过它。为此，您需要在确定它是Enter键后立即添加此声明。

It will move to the next row because that's what the ENTER key normally does. You need to tell it that you are handling it on your own and it should skip that. To do that, you need to add this statement right after you've determined that it's the Enter key.

e.Handled = True
