winform DataGridViewComboBoxColumn下拉框选中事件
winfrom DataGridView 中有一列DataGridViewComboBoxColumn。我对这个写事件也不是很
熟悉。所以在网上找资料。基本上都是这样写的
private void hpGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
//判断要处理的DataGridViewComboBoxColumn名称，若符合条件，编辑控件被强制转换为ComboBox以处理，添加SelectedIndexChanged事件
if (this.hpGridView1.CurrentCell.OwningColumn.Name == "clmTest")
{
((ComboBox)e.Control).SelectedIndexChanged += new EventHandler(ComboBox_SelectedIndexChanged);
}
}
/// <summary>
/// SelectedIndexChanged事件触发时需要进行的处理
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void ComboBox_SelectedIndexChanged(object sender, EventArgs e)
{
MessageBox.Show(((ComboBox)sender).Text);
}
