C＃DataGridView控件

Question

雙擊（粗糙代碼）后，我將控件添加到datagridview中：

DoubleClick
{  
    datagridview.Controls.Add(newControl);
    datagridview.ClearSelection();  //to be shure that any of cells are selected
    newControl.Focus();
    newControl.KeyUp += new KeyEventHandler(newControl_KeyUp);
}

和：

newControl_KeyUp(object sender, KeyEventArgs e)
{
    if(e.KeyCode == Keys.Enter || e.KeyCode == Keys.Tab || e.KeyCode == Keys.A)
    {
        Commit();
    }
}

我的新控件對Keys.A做出反應。 但它不會對選項卡和輸入做出反應。 當我單擊Enter或Tab時，只有datagridview選定的單元格發生更改。

由於Tab鍵可移動焦點，因此，如果可以，我建議您在較低級別上工作：

private void dataGridView1_DoubleClick(object sender, EventArgs e)
{
    Control newControl = new MyTextBox();

    dataGridView1.Controls.Add(newControl);
    dataGridView1.ClearSelection();  //to be sure that any of cells are selected  
    newControl.Focus();
}

class MyTextBox : TextBox
{
    protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
    {
        if (keyData == Keys.Enter || keyData == Keys.Tab || keyData == Keys.A)
        {
            Trace.WriteLine("Ok, key = " + keyData);
            return true;///Or false??? return to override the basic behavior
        } 
        return base.ProcessCmdKey(ref msg, keyData);
    }
 }
