我如何知道何时将绑定了WinForms ComboBox的数据填入数据? [英] How can I tell when a data bound WinForms ComboBox is done filling in the data?

问题描述

为什么WinForms中的ComboBox控件没有像DataGridView控件那样的DataBindingComplete事件?

我用一个DataSet填充一个组合框，其中包含要过滤DataGridView的项目.我可以正常工作，但是如何确定所有绑定了数据的项目何时已加载到ComboBox中，这样我才能第一次调用过滤器?

预先感谢您的帮助.

Why does the ComboBox control in WinForms not have a DataBindingComplete event like the DataGridView control?

I''m filling a Combobox from one DataSet with items to filter the DataGridView on. I got that working, but how do I tell when all the data bound items have finished loading into the ComboBox so I can then invoke the filter for the first time?

Thanks in advance for any help.

推荐答案

使用BindingSource，您将能够知道绑定何时完成.您可以注册到BindingComplete事件.

您可以在此处 BindingSource.BindingComplete事件 [ ^ ]

Using BindingSource you would be able to know when the binding is complete. You can register to BindingComplete event.

You can refer to the implementation here BindingSource.BindingComplete Event[^]
