hi for all i added gridview to show some table data
,but when I run the page it give me this message

Could not determine a MetaTable. A MetaTable could not be determined for the data source 'SqlDataSource1' and one could not be inferred from the request URL. Make sure that the table is mapped to the dats source, or that the data source is configured with a valid context type and table name, or that the request is part of a registered DynamicDataRoute.

and this is my full code

HTML

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"

For me, it turns out that in my grid view, the columns were bound as an "asp:DynamicField", not as a "asp:BoundField"

ie

changing my columns from something like so:

<columns> <asp:dynamicfield datafield="Id" headertext="Id" xmlns:asp="#unknown">
to this:

<columns> <asp:boundfield datafield="Id" headertext="Id" xmlns:asp="#unknown">
fixed it ;-)

Solution 2

changing columns from something like so:

C#

<Columns>
  <asp:DynamicField DataField="Id" HeaderText="Id" />
</Columns>

to this

<pre lang="c#"><Columns>
  <asp:BoundField DataField="Id" HeaderText="Id" />
</Columns>
