实体框架 - 将组合框绑定到规范化表字段 [英] Entity Framework - Bind Combobox to Normalised Table Field

问题描述

我目前正在尝试绑定一个实体到一个窗体，但我想有DataConfidenceLevel（见下文）绑定到一个组合框与ConfidenceDescription作为显示成员。

I am currently trying to bind an entity to a form however I want to have DataConfidenceLevel (see below) bound to a combobox with ConfidenceDescription as the display member. What is the correct way to populate the combobox?

（我目前正在使用WPF，但可以接受Winforms答案）

(I am currently using WPF but a Winforms answer is acceptable)

感谢

推荐答案

答案是

    comboBox.DataBindings.Add(new Binding("SelectedItem", this.dataBindingSource, "DataConfidenceLevel", true));
    comboBox.DataSource = db.DataConfidenceLevel;
    comboBox.DisplayMember = "ConfidenceDescription";
    comboBox.ValueMember = "ConfidenceLevelID";
