Datagridview不更新/刷新 [英] Datagridview not updating/refreshing

问题描述

我有一个DataGridView由一个来自DB的表的DataSet组成。当我删除一行时，它会在数据库中更新，但不会从GridView中删除。只有当我重新启动应用程序时，它才会从GridView中移除。

请帮忙

解决方案<这是一个非常简单的过程。

1）创建一个绑定源

2。）将此对象的数据源设置为您的数据集表。

3.）将DatagridView的数据源设置为绑定源对象。

代码示例：

  Dataset ds = new Dataset（）; 
 BindingSource bs = new BindingSource（）
 bs.Datasource = ds.Table [0]; 
 DatagridView.Datasource = bs; 
  

现在，您在DataTable中所做的任何更改都会自动影响到您的GridView。

I have a DataGridView made of a DataSet of a table from the DB. When I delete a row, it is updated in the database but it is not removed from the GridView. Only when I restart the application does it get removed from the GridView.

Please help

解决方案

This is a very simple process.

1.) Create a Binding Source

2.) Set the Datasource for this object to your Dataset Table.

3.) Set The datasource for your DatagridView as the Binding source Object.

Code Example:

Dataset ds = new Dataset();
BindingSource bs = new BindingSource()
bs.Datasource = ds.Table[0];
DatagridView.Datasource = bs;

Now, Any changes you make in the DataTable will ripple through to your GridView automatically.
