我有一个gridview自动连接sqldatasource1等。对于网格，我也有一个搜索文本框如果用户需要过滤记录它调用另一个（（sqldatasource2-另一个procuder））并把它放在同一个gridview ..，所以我需要将gridView.datasourceID更改为另一个sqldatasource onclick一个按钮..
注意： sqldatasource1和sqldatasource2返回相同的查询，
sqldatasource1：
的procudercreate proc AfficheDossiers
@Nom_GIAC varchar(50)
as
begin
select [ID_Dossier] as 'ID_Dossier'
,[ID_Entreprise] as 'ID_Entreprise'

sqldatasource2的发布者（（搜索）：

这是搜索文本和按钮：
Saisir la CNSS :
<asp:TextBox ID="CNSSTxt" class="TXTBOX" runat="server" Height="23px" placeholder="CNSS" style="font-family : Comic Sans MS, Arial, Tahoma; color:Red;"></asp:TextBox>
<asp:Button ID="BtnFiltrerCNSS" runat="server" Text="Filtrer" class="BTN" style="font-variant:small-caps;" />
这是gridview：

任何线索？
感谢，

在onclick按钮事件中设置
gridview.datasource = newDataSource;
然后调用
girdView.DataBind（）;
请告诉我这是否是你需要的。
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。这将加载模拟你的屏幕，你只需双击你想要点击事件的按钮。然后它会将您重定向到后面的代码（.aspx.cs）。在那个方法中你需要写这个。
我现在只说这个，因为我看到你的按钮没有onclick =“methodName”属性

您可以根据条件在代码中提供数据源。
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();
