The problem is that there is no datasource control on the form with the ID MyDataSource which is the value of the DataSourceID property of the GridView.
<asp:GridView ID="GridView1" runat="server" DataSourceID="MyDataSource"></asp:GridView>
<asp:SqlDataSource ID="MyDataSource" runat="server"></asp:SqlDataSource>
In the above example, I used a SqlDataSource. However, any datasource control will do and its ID value must match the value used in the DataSourceID attribute of the GridView.
Another thing to check is that the markup is valid. I.e., there are no missing angle brackets, nothing outside the form tag. Nothing on a content page with a Master page that is outside of a content area. etc.
This can also happen when the page uses a masterpage and the ObjectDataSource is in the scope of a different asp:content control
DataSourceID should be the ID of a datasource control on your page. If you are binding in the codebehind then do not set the DatasourceID.
just remove this from the gridview :
DataSourceID="MyDataSource"
if you fill it from the codebehind
first goto App_Data and create xml file
1-App_Data/ddlxmlFile.xml
2-Get xmldatasource from toolbox and give same datasourceid name to xmldatasource ID=""
