Procedure or function x has too many arguments specified - asp.net

Question

I have a gridview with the following SqlDataSource:
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnString%>"
SelectCommand="SELECT IDC, DESCPREVIEW, ADESCPREVIEW, DESC, ADESC, DATETOs, Active, HAVEIMG FROM CONTENT ORDER BY IDC DESC "
UpdateCommand="[SP_UPDATE_CONTENT]"
UpdateCommandType="StoredProcedure">
<UpdateParameters>
<asp:Parameter Name="IDC" Type="Int32" />
<asp:Parameter Name="DESCPREVIEW" Type="String" />
<asp:Parameter Name="DESC" Type="String" />
<asp:Parameter Name="DATETOs" Type="String" />
<asp:Parameter Name="active" Type="Boolean" />
</UpdateParameters>
</asp:SqlDataSource>
The Stored procedure has these parameters defined:
alter PROCEDURE [dbo].[SP_UPDATE_CONTENT]
#IDC AS INT,
#DESCPREVIEW AS NVARCHAR(800),
#DESC AS NVARCHAR(1500),
#DATETOs AS VARCHAR(10),
#active as bit
I am getting the following error on Update:
[SqlException (0x80131904): Procedure or function SP_UPDATE_CONTENT has too many arguments specified.]

Although these are the same exact parameters
What could be going wrong here?

Problem Solved.
Apparently the Update Command considered all the Selected fields in the SelectCommand as parameters.
So I minimized the selectCommand to the needed number of fields only.
SelectCommand="SELECT IDC, DESCPREVIEW, DESC, DATETOs, Active FROM CONTENT ORDER BY IDC DESC "
