Question

I m trying to set a LINQ query as the DataSource of a BindingNavigator control.

我在表格中增加了一个数据背景:

进口

x As New myDataManagerData ......

下面的法典允许我通过结果展示和理解:

Dim clubList = From c In ctx.clubs _
                   Select c

BindingNavigator1.BindingSource.DataSource = clubList

Each record is displayed nicely so far. In the Winform, all textboxes are duly binded to the datasource but my problem is:

我添加了《救助工具箱Button》,其编号为:ctx.SubmitChanges()

但是,它没有任何更新程序。

问题:I HAVE是否在“拯救儿童网”内撰写了完整的插入/更新林克程序?

和:

Dim newClub as new DataContext.Club newClub.Name = NameTextBox.Text newClub.Address.... Etc.

在避免行动发生之前,要求将Edit称作具有约束力的来源。
