VB:如何将 DataTable 绑定到 DataGridView? [英] VB: How to bind a DataTable to a DataGridView?

问题描述

我知道这是一个基本问题，已经被回答了数千次，但我做不到.

I know this is a basic question that has already been answered thousand times, but I can't make it work.

我在 Visual Studio 2010 中工作，并且在我的 Windows 应用程序中有两种表单.在第一个 (Main.vb) 中，用户输入他的输入并进行计算.在第二个(DataAnalysis.vb)中显示计算结果.

I am working in Visual Studio 2010 and have two forms in my Windows Application. In the first one (Main.vb), the user enters his inputs and the calculation takes place. In the second one (DataAnalysis.vb) the calculation results are displayed.

在 Main.vb 中，我创建了包含所有中间计算步骤的临时表:

In Main.vb, I create the temp table that will contains all the intermediary calculation steps:

Dim tableTempJDL As DataTable = New DataTable("TempJDL")
Dim column As DataColumn

column = New DataColumn("ID", GetType(System.Int32))
tableTempJDL.Columns.Add(column)

column = New DataColumn("PthObjekt", GetType(System.Double))
tableTempJDL.Columns.Add(column)

'further columns are after created using the same method

然后，在 DataAnalysis.vb 中，我尝试将 DataTable tableTempJDL 显示到 DataGridViewBerechnung 中:

Then, in DataAnalysis.vb, I try to display the DataTable tableTempJDL into the DataGridViewBerechnung:

Public bindingSourceBerechnung As New BindingSource()
Me.DataGridViewBerechnung.DataSource = Me.bindingSourceBerechnung

但后来我不明白如何填充DataGridView...

But then I don't understand how to fill the DataGridView...

推荐答案

简单来说，您可以通过以下方式将您的表作为 bindingsource 的数据源:

Simply, you can make your table as the datasource of bindingsource in following way:

 Me.bindingSourceBerechnung .DataSource = tableTempJDL

稍后，您可以通过以下方式在 datagridview 中绑定上述绑定源:

Later on, you can bind above binding source in your datagridview in following way:

 Me.DataGridViewBerechnung.DataSource = Me.bindingSourceBerechnung
