C# 使用Telerik radDropDownList

我有

Winforms

应用程序，我想使用

Telerik

控制器而不是

Winforms

控制器

我的应用程序有

组合框

，可以获取我所有的计算机

网络适配器

：

private NetworkAdapter selectedAdapter = null;
ComboBox comboBoxAdapter;

我的机器适配器类型为

网络适配器

。 应用程序启动后，我将获得所有适配器：

IEnumerable<NetworkAdapter> res = NetworkAdapter.getAll();

和

ComboxAdapter\u选择的索引已更改
：

private void comboBoxAdapter_SelectedIndexChanged(object sender, EventArgs e)
{
    ComboBox cmb = sender as ComboBox;
    selectedAdapter = cmb.SelectedItem as NetworkAdapter;
}

现在我添加了
Telerik radDropDownList
由于
Telerik radDropDownList
AddRange仅接收
string
我将所有
网络适配器
放在
列表中
：

出于某种原因，
selectedAdapter
总是
null
只是想知道为什么你仍然使用ComboBox来转换发送者（在你最后的方法上）

我想应该是这样

private void radDropDownList1_SelectedIndexChanged(object sender, Telerik.WinControls.UI.Data.PositionChangedEventArgs e)
{
    var cmb = sender as RadDropDownList;
    selectedAdapter = cmb.SelectedItem as NetworkAdapter;
}

虽然我不确定

List<string> addList = new List<string>();

foreach (NetworkAdapter add in NetworkAdapter.getAll())
    addList.Add(add.Description);

radDropDownList1.Items.AddRange(addList);

private void radDropDownList1_SelectedIndexChanged(object sender, Telerik.WinControls.UI.Data.PositionChangedEventArgs e)
{
    ComboBox cmb = sender as ComboBox;
    selectedAdapter = cmb.SelectedItem as NetworkAdapter;
}

private void radDropDownList1_SelectedIndexChanged(object sender, Telerik.WinControls.UI.Data.PositionChangedEventArgs e)
{
    ComboBox cmb = sender as ComboBox;
    selectedAdapter = cmb.SelectedItem as NetworkAdapter;
}

private void radDropDownList1_SelectedIndexChanged(object sender, Telerik.WinControls.UI.Data.PositionChangedEventArgs e)
{
    var cmb = sender as RadDropDownList;
    selectedAdapter = cmb.SelectedItem as NetworkAdapter;
}
