Answer 1

问题是表单上没有数据源控件，其ID为MyDataSource，这是DataSourceID的{{1}}属性的值。

GridView

在上面的示例中，我使用了<asp:GridView ID="GridView1" runat="server" DataSourceID="MyDataSource"></asp:GridView> <asp:SqlDataSource ID="MyDataSource" runat="server"></asp:SqlDataSource>。但是，任何数据源控件都可以，并且其ID值必须与GridView的SqlDataSource属性中使用的值匹配。

要检查的另一件事是标记有效。即，DataSourceID标签之外没有丢失尖括号，没有任何内容。内容页面上没有内容页面之外的主页面。等

Answer 2

当页面使用母版页并且ObjectDataSource属于不同asp:content控件的范围时，也会发生这种情况

Answer 3

DataSourceID应该是页面上数据源控件的ID。如果您在代码隐藏中绑定，则不要设置DatasourceID。

Answer 4

从gridview中删除它：

DataSourceID="MyDataSource"

如果你从代码隐藏

填写它

Answer 5

首先转到App_Data并创建xml文件

1-App_Data / ddlxmlFile.xml
2-从工具箱中获取xmldatasource并将相同的datasourceid名称赋予 xmldatasource ID =“”

'GridView1'的DataSourceID必须是IDataSource类型的控件的ID
