Question

我已将 EditMode 属性设置为 EditorEnter ，然后单击即可访问该下拉列表。

在gridcellclick上写了代码

 If (e.ColumnIndex == 5)
{
SendKeys.SendWait("{F4}")
}

并且还编写了代码

private void comboBox1_Enter(object sender, System.EventArgs e)
{
comboBox1.DroppedDown = true;
}

但结果是一样的。我无法通过单击访问下拉列表。只需点击两下即可打开下拉列表。

更新：

private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
        {
                ComboBox combo = e.Control as ComboBox;
     if (combo != null)
                {
                    combo.Enter -= new EventHandler(combo_Enter);
                    combo.Enter += new EventHandler(combo_Enter);
                }
         }

对我来说很好：

private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
    ComboBox comboBox = e.Control as ComboBox;
    if (comboBox != null)
    {
        comboBox.Enter -= comboBox_Enter;
        comboBox.Enter += comboBox_Enter;
    }
}

private void comboBox_Enter(object sender, EventArgs e)
{
    ((ComboBox)sender).DroppedDown = true;
}

在datagrid winforms中单击即可打开下拉列表
