我有一个自动与 sqldatasource1 等连接的 gridview。对于网格，我还有一个搜索文本框，所以我需要将gridView.datasourceID更改为另一个sqldatasource onclick a button ..

注意： sqldatasource1 和 sqldatasource2 返回相同的查询，

sqldatasource1 的生产者：

create proc AfficheDossiers
@Nom_GIAC varchar(50)
as
 begin
 select [ID_Dossier] as 'ID_Dossier'
      ,[ID_Entreprise] as 'ID_Entreprise'
      ,[Date_Depot] as 'Date_Dépôt'

      ,[Duree] as 'Durée'
      ,[Porcentage_Taux] as 'Pourcentage,Taux' from Dossier where Nom_Giac = @Nom_GIAC 
 end

sqldatasource2((searche) 的生产者：

这是搜索文本和按钮：

这是网格视图：

       </div>

有什么线索吗？

谢谢，

在刚刚设置的onclick按钮事件中

gridview.datasource = newDataSource;

然后调用

girdView.DataBind();

让我知道这是否是您需要的。

如果您使用的是 Visual Studio 2010，则需要单击 .aspx 文件，然后单击窗口右下角的设计视图。这将加载您的屏幕模型，您只需双击您想要点击事件的按钮。然后它会将您重定向到 (.aspx.cs) 文件后面的代码。在那个方法中是你需要写这个的地方。

我现在才这么说是因为我看到您的按钮没有 onclick="methodName" 属性

您可以根据条件在后面的代码中给出数据源。

   if(someCondition)
       myStoredProcedure = "storedProc1";
    else
       myStoredProcedure = "storedProc2";

    SqlDataSource dataSource = new SqlDataSource(ConfigurationManager.ConnectionStrings["connstr"].ConnectionString, searchQuery);
    dataSource.SelectCommandType = SqlDataSourceCommandType.StoredProcedure;
    dataSource.SelectCommand = myStoredProcedure;
    dataSource.ID = "myDataSource";

   // Your code to set datasource to grid

   gridBookings.DataSourceID = dataSource.ID;
   gridBookings.DataBind();
