将SQL数据插入列表框 [英] Insert sql data into listbox

问题描述

运行此代码时，我的listbox为空.从SQL获取数据并将其放入listbox的最佳方法是什么?提交表单后，我想使用CustomreID值数据存储到另一个表中，并认为使用索引将是最佳解决方案.

When I run this code my listbox is empty. What is the best way to get data from SQL and into a listbox? When the form is submitted I want to use the CustomreID value data to store into another table and thought using the index would be the best solution.

sSQL = "SELECT CustomerID, Company from Customers Order by Company ASC"

cmd = New SqlCommand(sSQL, moConn)
rs = cmd.ExecuteReader()

While rs.Read
   lsbDestination.Items.Insert(CInt(rs("CustomerID")), rs("Company"))
End While

推荐答案

您可以使用ListBox的DataSource属性轻松地将数据绑定到ListBox.尝试这样的事情(未经测试):

You can easily bind data to a ListBox using the DataSource property of the ListBox. Try something like this (untested):

Dim adapter As New SqlDataAdapter(cmd)
Dim ds As New DataSet
adapter.Fill(ds)

lsbDestination.DataTextField = "Company"
lsbDestination.DataValueField = "CustomerId"
lsbDestination.DataSource = ds.Tables(0)
lsbDestination.DataBind()

祝你好运.
