将文本框绑定到SQLDataSource选择的字段(VB.NET)
原标题:Bind a Text Box to a Field Selected by SQLDataSource (VB.NET)

我正在寻找将数据从SqlDataSource绑定到VisualStudio2008中丢弃的文本框的最简单方法。

例如,我目前有4个文本框,分别为“地址”、“城市”、“州”和“邮编”。页面上还有一个SqlDataSource,用于获取记录的ID并根据ID选择这4个字段。

如何将每个框快速绑定到所选的特定字段?我认为这将是非常直接的,但似乎不是。似乎答案是必须创建一个GridView或某种类型的控件。

温柔一点。。。我是个疯子:)

一般来说,您是正确的,如果您想使用数据绑定,则需要使用适当的控件。对于这个例子,我建议使用FormView——它旨在显示单个数据库记录的结果,并使用模板,这意味着您将完全控制输出。这篇文章可能是一个很好的起点:FormView控件:逐步

要读取代码隐藏类中绑定到FormView的值,您需要为FormView的DataBound事件创建一个事件处理程序。在该事件处理程序中,您将通过FindControl以编程方式引用控件,如下所示:

Dim myLabel As Label = CType(FormViewID.FindControl("id"), Label)

这里,id将是您感兴趣的标签值的id。一旦您引用了标签,您就可以使用myLabel.Text获取其值。
