WPF ComboBox...how to set the .Text property?
提问by AngryHacker
Is there a way to set the .Textproperty of the Wpf ComboBox control directly?
有没有办法直接设置.TextWpf ComboBox控件的属性？
My combobox is bound to a List<T>collection, but when I try to set .Textproperty in the DropDownClosedevent, it totally ignores it.
我的组合框绑定到一个List<T>集合，但是当我尝试.Text在DropDownClosed事件中设置属性时，它完全忽略了它。

If you're trying to set the text to the text of one of the items in the list it should work correctly.
如果您尝试将文本设置为列表中某一项的文本，它应该可以正常工作。
If you're trying to set it to an item that isn't in the list then the IsEditable property needs to be true. You can set the IsReadOnly property to true if you don't actually want users typing into the combo box.
如果您尝试将其设置为不在列表中的项目，则 IsEditable 属性需要为 true。如果您实际上不希望用户在组合框中键入内容，则可以将 IsReadOnly 属性设置为 true。
If none of these cases fit you, can you post the code you're using?
如果这些情况都不适合您，您可以发布您正在使用的代码吗？

You can also try adding one more ComboBoxItem with Visibility=Collapsed, set that one as the selected item and set its content to whatever is needed.
您还可以尝试添加一个 Visibility=Collapsed 的 ComboBoxItem，将其设置为所选项目并将其内容设置为所需的任何内容。
