填充以编程方式制作的组合框（不在设计器中） [英] Populate a programmatically made combobox(not in designer)

问题描述

大家好，



我想问你是否知道如何填充编程组合的组合框。我在编程方面的意思是它不在设计师中。这意味着很多。



谢谢！ ：）

解决方案

或者您可以设置组合框的数据源并直接从数据表填充它，例如：

 cbCountry.DataSource = CustomSQL.GetCountryList 
 cbCountry.DisplayMember =   Country 
 cbCountry.ValueMember =   Country 
 cbCountry.Text = cbCountry.Items（ 226 ）。ToString 

此示例使用从CustomSQL.GetCountryList返回的数据表中的国家列表填充组合框，然后预选英国（列表中的项目226）作为文本。

你有什么试图得到你的答案？我什么都没假......因为这是一个非常基本的任务。

参见： http://msdn.microsoft.com/en-us/library/system.windows.forms。 combobox.items.aspx？cs-save-lang = 1& cs-lang = vb＃code-snippet-2 [ ^ ]

你填充它调用 Items 属性的 Add 方法，例如

 myComboBox.Items.Add（ 第一项）

Hi All,

I would like to ask if you know how to populate a programatically made combobox. What I mean in programatically is that it is not in the designer. It will mean a lot.

Thank you! :)

解决方案

Or you can set the Datasource of the combobox and populate it directly from a datatable, for example:

cbCountry.DataSource = CustomSQL.GetCountryList
cbCountry.DisplayMember = "Country"
cbCountry.ValueMember = "Country"
cbCountry.Text = cbCountry.Items(226).ToString

This example populates a combobox with a list of countries from a datatable returned from 'CustomSQL.GetCountryList' and then preselects UK (item 226 in the list) as the text.

What have you tried to get your answer? I assume nothing... since this is a really basic task.
See: http://msdn.microsoft.com/en-us/library/system.windows.forms.combobox.items.aspx?cs-save-lang=1&cs-lang=vb#code-snippet-2[^]

You populate it calling the Add method of its Items property, e.g.

myComboBox.Items.Add("first item")
