在窗体上绑定多个ComboBox C＃ [英] Bind multiple ComboBox on a form C#

问题描述

这似乎是一个简单的任务，但可能有一个更简单的方法。

This seems like a simple task but there may be an easier way.

我有一个包含30个组合框的表单，它们都需要相同的数据集。目前我绑定每一个：

I have a form with 30 comboboxes that all need the same data set. Currently I bind each one:

DataTable t = GetData();

this.ComboBox1.DataSource = t;
this.ComboBox1.DisplayMember = "heading";

this.ComboBox2.DataSource = t;
this.ComboBox2.DisplayMember = "heading";

this.ComboBox3.DataSource = t;
this.ComboBox3.DisplayMember = "heading";

...
...

this.ComboBoxN.DataSource = t;
this.ComboBoxN.DisplayMember = "heading";

有没有办法以更少的tedius方式绑定所有？

Is there a way to bind them all in a less tedius fashion?

感谢。

推荐答案

foreach (var control in this.Controls)
{
    if (control is (ComboBox))
    {
        ((ComboBox)control).DataSource = t;
        ((ComboBox)control).DisplayMember = "heading";
    }
}
