ADGV C＃DataGridView - 以编程方式调用CellLeave事件

Question

我正在尝试使用自动生成的advancedDataGrid - ADGV（adgv.codeplex.com）。 目前的问题类似于之前解决的问题：my previous stackoverflow.com question

我有一个表单（frmLev），其中advancedDataGrid填充了SQL中的数据。 DataGridView的一列是日期字段（DD.MM.YYYY），其中放置了DateTimePicker。

如果我做对了......问题在于，只有当用户在DatePicker中选择日期后手动完成单元格编辑时，整行才会保存到SQL。单元格看起来像编辑完成，但必须通过单击，按Enter或选项卡再次确认。其他文本单元格选择了文本或闪烁光标。

我想在delDatePick_textChange（）结束时将行保存到SQL，但此时调用currentRowSave（）将无效。用户必须先执行单击。仅当levDGV_CellLeave（）获取事件时才会保存数据。

问题是：如何以编程方式触发CellLeave事件？

MetroFramework.Controls.MetroDateTime delDatePick = new MetroFramework.Controls.MetroDateTime();
Rectangle _Rectangle; 


    private void frmLev_Load(object sender, EventArgs e)
    {
        //Add DateTimePicker to Date
            levDGV.Controls.Add(delDatePick);
            delDatePick.Visible = false;
            delDatePick.Format = DateTimePickerFormat.Short;
            delDatePick.TextChanged += new EventHandler(delDatePick_textChange);
            delDatePickValueAutomatic = false;
    }

private void levDGV_CellClick(object sender, DataGridViewCellEventArgs e)
    {
        switch (levDGV.Columns[e.ColumnIndex].HeaderText)
        {
            case "Datum":
            _Rectangle = levDGV.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex, true);
            delDatePick.Size = new Size(_Rectangle.Width, _Rectangle.Height);
            delDatePick.Location = new Point(_Rectangle.X, _Rectangle.Y);
            delDatePick.Visible = true;
                if (levDGV.CurrentCell.Value != DBNull.Value)
                {
                    delDatePick.Value = (DateTime)levDGV.CurrentCell.Value;
                    delDatePickValueAutomatic = true;
                }
            break;
        }
    }

private void delDatePick_textChange(object sender, EventArgs e)
    {
        if (delDatePickValueAutomatic != false) // event fired when cell gets focused, so skipping
        {
            String pickedDate = delDatePick.Text.ToString();
            delDatePick.Visible = false;

            this.BeginInvoke((MethodInvoker)delegate ()
            {levDGV.CurrentCell.Value = pickedDate;});
            levDGV.Refresh();
            delDatePick.Visible = false;
            //I want to update SQL row here, but calling currentRowSave() will not work at this moment because row is in edit mode...
        }
    }

private void levDGV_CellLeave(object sender, DataGridViewCellEventArgs e)
    {
        //skipping first entrance;
        if (e.ColumnIndex != 0 && e.RowIndex != 0)
        {
            delDatePick.Visible = false;
            currentRowSave();
        }
    }

private void currentRowSave()
    {
        int rowIdx = levDGV.CurrentCell.RowIndex;
        DataRowView drv = (DataRowView)levDGV.Rows[rowIdx].DataBoundItem;
        DataRow dr = drv.Row;
        BeginInvoke((Action)(() => SaveRowChanges(dr)));
    }

Answer 1

您也可以调用单元格的EndEdit（）方法。像这样：

this.BeginInvoke((Action)(() => levDGV.CurrentCell.EndEdit()));

Answer 2

找到一个解决方法......它没有回答我的问题，但对我有用。

this.BindingContext[levDGV.DataSource].EndCurrentEdit(); //does not call CellLeave
currentRowSave();
