ObjectDataSource SelectParameters

[btreddy]

Hii all,

I've a problem regarding passing select parameters to objectdatasource from code behind.

i would like to pass the select parameters to a objectdatasource ..not in the selecting or selected event of the objectdatasource but some where in the one of button click event.

i tried of adding the parameters but it didn work for me..

<asp:ObjectDataSource ID="ODSEditSchedules" TypeName="Schedules" runat="server" SelectMethod="GetParticipants">
</asp:ObjectDataSource>
 

GetParticipants is the method from DAL which takes one string as a parameter.

im adding the select parameters in a seperate button click event

 ObjectDataSourceEditParticipants.SelectParameters.Clear();
 ObjectDataSourceEditParticipants.SelectParameters.Add("xxxxxx", xxxxxlabel.Text.ToString());
 

its throwing an erro saying that there is no GetParticipants method which takes Zero parameters...

and if add the select parameters to the objectdatasource..with some default value to the parameter thn its working.

 <asp:ObjectDataSource ID="ODSEditSchedules" TypeName="Schedules" runat="server" SelectMethod="GetParticipants">
                    <SelectParameters>
                        <asp:Parameter Name="xxxx" Type="string" DefaultValue="xxxxx"/>
                    </SelectParameters>
                </asp:ObjectDataSource>
 
 

Kindly tell me wht im missing .

Thanks in advance

In your code-behind, you are referencing the ObjectDataSource by 'ObjectDataSourceEditParticipants', but in your UI layer, it's id is 'ODSEditSchedules'. This seems like a different error than what you say is being reported to you but it is definitly an error.
