具有单个DataSource的多个ComboBox [英] Multiple ComboBox with single DataSource

问题描述

我有2个组合框，它们绑定到数据集中的单个绑定源。当我在一个组合框中选择一个项目时，它们都会改变。我自己的组合框中没有代码，但确实有数据集填充：

I have 2 combo boxes that are tied up to a single binding source in a dataset. When I select an item in one of the combo boxes, they both change. I don't have code in the combobox themselves but I do have the dataset fill:

this.cLIENT_BranchesTableAdapter.Fill(this.gcDataSet.CLIENT_Branches);

这可能是什么原因？

推荐答案

为每个ComboBox赋予自己的BindingSource：

Give each ComboBox their own BindingSource:

comboBox1.DataSource = new BindingSource(source, string.Empty);
comboBox2.DataSource = new BindingSource(source, string.Empty);
