组合框 [英] Combo Box

问题描述

我有一个组合框，我想在点击保存按钮后刷新数据。我知道在web开发人员中你可以说datasource.databind，但我在vb.net中没有看到。请有人帮帮我。

I have a combo box that I want to refresh the data of after the save button is clicked. I know that in web developer you can just say datasource.databind but I do not see that in vb.net. Please can someone help me out.

推荐答案

我很确定组合框有数据源属性。

I''m pretty sure a combobox has a datasource property.

是的，组合框有一个数据源，但我的问题是在我将数据保存到数据库后刷新该数据源。当我这样做时，我看到了：mycombobox.refresh（），它重复组合框中的数据。

Yes, a combo box has a datasource but my question is to refresh that datasource after I saved something to the database. I saw that when I do: mycombobox.refresh() that it repeats the data in the combobox.

这有点离开我的区域但是......

如果将数据源设置为null - 强制清除 - 然后将数据源设置回数据库 - 强制它获取最新值，该怎么办？

This is getting a little out of my area but...
What if you set the datasource to null - forcing a clear - then set the datasource back to the database - forcing it to obtain the most current values?
