使用enter键覆盖datagridview的导航

您需要做的就是处理DataGridView的KeyDown事件,并在处理程序中检查当前按下的键是否为Enter键。如果是这样,只需将DataGridView的CurrentCell设置为下一个单元格(还要检查这是否是行中的最后一个单元格,在这种情况下,移动到下一行的第一个单元格。)

Private Sub DataGridView1_KeyDown(ByVal sender As Object, ByVal e As KeyEventArgs) Handles DataGridView1.KeyDown
  If e.KeyCode = Keys.Enter Then
    Dim numCols As Integer = DataGridView1.ColumnCount
    Dim numRows As Integer = DataGridView1.RowCount
    Dim currCell As DataGridViewCell = DataGridView1.CurrentCell
    If currCell.ColumnIndex = numCols - 1 Then
      If currCell.RowIndex < numRows - 1 Then
        DataGridView1.CurrentCell = DataGridView1.Item(0, currCell.RowIndex + 1)
      End If
    Else
      DataGridView1.CurrentCell = DataGridView1.Item(currCell.ColumnIndex + 1, currCell.RowIndex)
    End If
    e.Handled = True
  End If
End Sub

Private Sub DbGDetail_KeyDown(sender As Object, e As System.Windows.Forms.KeyEventArgs) Handles DbGDetail.KeyDown
    If e.KeyCode = Keys.Enter Then
        SendKeys.Send("{Tab}")
        e.Handled = True
    End If
End Sub


Private Sub DbGDetail_CellEndEdit(sender As Object, e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DbGDetail.CellEndEdit

    SendKeys.Send("{up}")
    SendKeys.Send("{Tab}")

End Sub

我找到了进去所需的帮助 this link 具体在 张荣春对分类的反馈 DataGridView ProcessDialogKey

请注意,在这种情况下,我只是将CurrentCell留在原地,但可以在调用“return true”之前重新分配它。

public class DataGridViewAddRow : DataGridView
{

    protected override bool ProcessDialogKey(Keys keyData)
    {

        //cell is in Edit mode

        if (keyData == Keys.Enter)
        {

            if (this.CurrentCell.RowIndex == this.Rows.Count-2)
            {                            
                return true;
            }

        }

        return base.ProcessDialogKey(keyData);

    }

}

当按下VB.net的Enter键时,DataGridView会聚焦到下一个单元格或列:

如果是├1.CurrentCell。ColumnIndex=ViewModel 1.ColumnCount-1然后 ViewModel 1.CurrentCell=ViewModel 1.项(0,ViewModel 1.Currentell.RowIndex+1) 其他的 语句结束
