我有一个下拉的在代码中填入数据背后列表。在 DataTextField 属性设置为以下代码：

I have a drop down list that is populated with data in the code behind. The DataTextField attribute is set with the following code:

ddlItems.DataTextField = "ItemName";

我想作为 DataTextField 。我试着用下面的代码，但没有奏效。而且我已经研究在网上也没有找到如何使用两个数据的属性。

I want to display two data properties as the DataTextField. I tried using the following code but it didn't work. And I have researched on the net but couldn't find how to use two data properties.

ddlItems.DataTextField = "ItemName" + "ItemDescription";

推荐答案

您可以使用ddlItems的格式化事件，这将让你的逻辑设置如何某个项目转换为字符串，或者如果它使任何意义的使用。你的程序，有这样RepresentingString返回名称+说明，并绑定到该属性的属性。

You can use the Formatting event of ddlItems which will allow you to set logic to how to convert a certain item to a string, or if it makes any sense to use in your program, have a property like RepresentingString that returns Name + Desc, and bind to that property.
