如何将文本值添加到组合框 [英] How to add textual values to a Combo Box

问题描述

我想在后面的代码中向ASP.Net中的ComboBox添加文本值。

有谁知道我怎么做到这一点？

I want to add textual values to a ComboBox in ASP.Net in the code behind.
Does anyone know how I can achieve this?

推荐答案

您可以通过两种方式完成：

1.您可以更改数据源并重新绑定DropDownList。

2.在DropDownList中插入项目TextBox的TerxtChanged事件（AutoPostBack属性应该为true，以便文本框触发服务器端事件）。试试这个：

You can do it in two ways:
1. Either you can alter your datasource and rebind the DropDownList.
2. Insert the items in DropDownList in TerxtChanged event of your TextBox(AutoPostBack property should be true for textbox to fire server side event). Try this:

drpList.Items.Insert(0, new ListItem(TextBox1.Text.Trim(), TextBox1.Text.Trim()));

--Amit

--Amit

使用

Use

//Code here to populate DropDownList
DropDownListID.Items.Insert(0, new ListItem("text", "value")
///
///  0 is the index at which you want to insert the text. Text means the text
///  which is shown to the user and value is a unique value (enum or a number) 
///  which can be used in the code-behind to uniquely identify a dropdown item.
