在C＃中动态在RadComboBox中添加项目

Question

I'm trying to add Items to RadComboBox dynamically. It's supposed to work like this: I have an editable RadComboBox and a Button . Any text I type into RadComboBox should be saved as a new Item on a Button_Click and I should be able to see it in a dropdown list and select it. Thank you for your help.

First, I would like you to read this in the Telerik documentation: docs

It will help you understand how bindings work for the RadComboBox.

How would I solve your problem? I'd follow these steps:

• Bind your RadComboBox to an ObservableCollection<Item> . Make sure that Item implements onPropertyChanged()
• Execute an event when a button is pressed (either through just code-behind, but I prefer ICommand, MVVM style)
• In the event I described above, create an Item and add it to your ObservableCollection<Item> .

If you have a problem following any of those steps, put a comment below and I'll try to help.
