id="SqlDataSource1"
runat="server"
datasourcemode="DataSet"
connectionstring="<%$ ConnectionStrings:MyNorthwind%>"
selectcommand="getordertotal"
onselected="OnSelectedHandler">
<selectparameters>
<asp:querystringparameter name="empId" querystringfield="empId" />
<asp:parameter name="total" type="Int32" direction="Output" defaultvalue="0" />
<asp:parameter name="_ret" type="Int32" direction="ReturnValue" defaultvalue="0" />
</selectparameters>

Remarks
The type can be used to create strongly typed parameters, so that values are converted correctly between your Web application and underlying code.
If the type of the parameter is changed, the OnParameterChanged method is called.
