在我的代码中我有了combobox,我通过bindingData控件绑定它。我使用selectIndexChanged为组合框中的每个活动项做一些代码..
我的问题是在这种情况下: 我的bindingData为空(所以组合框索引= -1)然后我将项目“item1”添加到我的bindingData(活动组合框项目是“item1”),但SelectIndexChanged没有触发。为什么?
代码:
//first combobox is empty
myBindingSource.DataSource = null;
comboBox_Choixpiece.DataSource = myBindingSource;
//then combobox Contains 1 item but SelectIndexChanged event is not firing !!
myBindingSource.DataSource = someSource;
comboBox_Choixpiece.DataSource = myBindingSource;
请帮帮我
