Question

有没有办法将DateTimePicker控件放在DataGridView中？

我检查了所有可能的属性，但它提供了复选框，组合框等选项，但不提供DateTimePicker。

Answer 1

您没有错过任何内置选项，但可以将DataGridViewColumn和DataGridViewCell类子类化为托管您选择的任何控件。

MSDN上的这篇文章更详细地解释了这个过程，甚至还包括一些示例代码：
How to: Host Controls in Windows Forms DataGridView Cells

您还可以在代码项目中找到完整的示例：Generic DataGridView V2.0

private void dgtest_CellClick(object sender, DataGridViewCellEventArgs e)
    {
        if (e.ColumnIndex == 0)
        {
             dtp = new DateTimePicker();
            dgtest.Controls.Add(dtp);
            dtp.Format = DateTimePickerFormat.Short;
            Rectangle Rectangle = dgtest.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex, true);
            dtp.Size = new Size(Rectangle.Width, Rectangle.Height);
            dtp.Location = new Point(Rectangle.X, Rectangle.Y);

            dtp.CloseUp += new EventHandler(dtp_CloseUp);
            dtp.TextChanged += new EventHandler(dtp_OnTextChange);


            dtp.Visible = true;
        }
    }
    private void dtp_OnTextChange(object sender, EventArgs e)
    {

        dgtest.CurrentCell.Value = dtp.Text.ToString();
    } 
    void dtp_CloseUp(object sender, EventArgs e)
    { 
        dtp.Visible = false;
    }

要解决在DataGridView中使用DateTimePicker时的一些输入问题，您需要将以下内容添加到上面引用的Microsoft示例中。花了很长时间才找出valuechanged事件未按预期触发的问题。修复来自这里（stackoverflow）并转换为下面的C＃。在这里添加这些信息似乎很合适，因为我在搜索DataGridView和DateTimePicker时不断发现这个论坛帖子。

    protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
    {

        switch (keyData & Keys.KeyCode)
        {
            case Keys.Enter:
            case Keys.Tab:
                this.dataGridView.Focus();
                break; 
        }

        return base.ProcessCmdKey(ref msg, keyData);

    }

也许这不是正确的，但是简单的技巧和相同的结果........少了很少的代码......我只是在玩，虽然在盒子外面，只是设置

我隐藏它直到他们点击单元格，或者你可以显示首先我宣布：

DateTimePicker1.Visible = False

单击单元格时，运行此代码...

    DateTimePicker1.Visible = True
    ActiveControl = DateTimePicker1

然后在

下面

 Public Sub DateTimePicker1_ValueChanged(sender As System.Object, e As System.EventArgs) Handles DateTimePicker1.ValueChanged



    requestDGV.Rows(0).Cells("requestTimeOff").Value = (DateTimePicker1.Value)
    DateTimePicker1.Visible = False
    DateTimePicker1.Enabled = False

End Sub

Super Basic，我把它直接放在盒子里，看起来不合适

或超级简单的模式.......我只是想隐藏我的直到列点击

Public Sub DateTimePicker1_ValueChanged(sender As System.Object, e As System.EventArgs) Handles DateTimePicker1.ValueChanged


    requestDGV.Rows(0).Cells("requestTimeOff").Value = (DateTimePicker1.Value)

End Sub

你真的只需要一行.....数据将在网格中，只需要少得多的代码......

Answer 5

好吧...使用@rajat和@Aaron的一些示例，我制作了一个在DateTimePicker单元中弹出的示例。谢谢大家。

Private Sub DataGridView1_CellClick(sender As Object, e As DataGridViewCellEventArgs) Handles DataGridView1.CellClick

    If e.ColumnIndex = 8 Then 'CHECK IF IT IS THE RIGHT COLUMN

        'SET SIZE AND LOCATION
        Dim rect = DataGridView1.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex, True)
        DateTimePicker1.Size = New Size(rect.Width, rect.Height)
        DateTimePicker1.Location = New Point(rect.X + 10, rect.Y + 76) 'USE YOU OFFSET HERE

        DateTimePicker1.Visible = True
        ActiveControl = DateTimePicker1

    End If

End Sub


Private Sub DateTimePicker1_ValueChanged(sender As Object, e As EventArgs) Handles DateTimePicker1.ValueChanged

    If DataGridView1.RowCount > 0 Then 'JUST TO AVOID FORM LOAD CRASH

        DataGridView1.CurrentCell.Value = DateTimePicker1.Value.ToShortDateString
        DateTimePicker1.Visible = False

    End If

Answer 6

我认为DateTimePicker上的CloseUp事件更合适，因为更改的值会在任何更改时触发，而CloseUp仅在选择整个日期时触发
