我可以DataGridView.EndEdit触发CellValidating事件？ [英] Can I make DataGridView.EndEdit trigger the CellValidating event?

问题描述

我用在我的WinForms应用程序中的DataGridView。我的主要目标是使输入键不移动到网格中的下一行。我还是想回车键确认并结束编辑模式。

I'm using a DataGridView in my WinForms application. My main objective is to make the Enter key not move to the next row in the grid. I still want the enter key to validate and end edit mode.

我发现的此FAQ条目和子类的DataGridView覆盖ProcessDialogKey（）。如果按下的键是输入，我叫EndEdit中（），否则我叫base.ProcessDialogKey（）。

I found this FAQ entry and subclassed DataGridView to override ProcessDialogKey(). If the key pressed is Enter, I call EndEdit(), otherwise I call base.ProcessDialogKey().

它的伟大工程，除了CellValidating事件不被解雇。

It works great, except the CellValidating event isn't fired.

目前，我只是手动调用我的验证逻辑之前，我打电话EndEdit中，但它看起来像我想的东西。

Currently, I'm just manually calling my validation logic before I call EndEdit, but it seems like I'm missing something.

我想我可以打电话OnCellValidating，但随后我会担心我失去了一些其他的事件。我真正想要的是行为就像按与添加禁用一个网格的最后一行进入EndEdit中（）的一番风味。

I guess I could call OnCellValidating, but then I'd be worried I'm missing some other event. What I really want is some flavour of EndEdit() that behaves just like pressing enter on the last row of a grid with adding disabled.

推荐答案

CellValidating不会被调用，直到您更改CurrentCell。所以我解决这个kludged的方式是改变CurrentCell，然后切换回当前的。

CellValidating doesn't get called until you change the CurrentCell. So the way I kludged around this was to change the CurrentCell, then switch back to the current one.

    protected override bool ProcessDialogKey(Keys keyData)
    {
        if (keyData == Keys.Enter)
        {
            DataGridViewCell currentCell = CurrentCell;
            EndEdit();
            CurrentCell = null;
            CurrentCell = currentCell;
            return true;
        }
        return base.ProcessDialogKey(keyData);
    }
