I’m trying to make my own ObjectDataSource in my .NET Web Project. This is my approach:

I have a class that returns an object (called from WCF). The object is consumed by a ObjectDataSource. The ObjectDataSource has a selectmethod that picks up the object I’ve created in my class.

When the user clicks a button, the method is called and filled with parameters so and the object is filled with the result from WCF. The object has a return value but their isn’t anything appearing in my DataGrid.

Do I need to fill the ObjectDataSource object? Does it doesn’t this automatically when the method is fired? Am I missing something?

Any help is appreciated!!

1    
2       "ObjectDataSource1" runat="server" 
3            SelectMethod="getWCFObject" 
4            TypeName="MyApp.MyObjectClass">
5            
6                "id" Type="String" />
7                "businessProcessStepId" Type="String" />
8                "businessProcessStepType" Type="String" />
9                "handledStatusCollection" Type="Object" />
10               "serviceStatusCollection" Type="Object" />
11               "succeeded" Type="Boolean" />
12               "startDate" Type="DateTime" />
13               "endDate" Type="DateTime" />
14               "environmentId" Type="Int32" />
15               "rowCount" Type="Int32" />
16           
17       
18   
19   "myGrid" runat="server" DataSourceID="ObjectDataSource1" 
20                   AutoGenerateColumns="False" CellPadding="4" ForeColor="#333333" 
21                   GridLines="None">
22           "#990000" Font-Bold="True" ForeColor="White" />
23           "#FFFBD6" ForeColor="#333333" />
24           "#FFCC66" ForeColor="#333333" HorizontalAlign="Center" />
25           "#FFCC66" Font-Bold="True" ForeColor="Navy" />
26           "#990000" Font-Bold="True" ForeColor="White" />
27           "White" />

Hi rudy1250,

Since you've bind the ObjectDataSource to a DataGird, the SelectMethod of ObjectDataSource will be automaticlly called when DataGrid calls DataBind method OR specify DataSourceID property. But you said there's nothing in dataGrid. So I suggest you can set break points in the GetWCFObject method, and debug your application. In this case, you can easily see how the method returns a null result. Hope this helps you!

Thanks.

 well it was about the parameters not be filled in in the selection method of the ODS.

protected void myQuery_Selecting(object sender, ObjectDataSourceSelectingEventArgs e)
        {


            e.InputParameters["paramhere"] = null;

        } 

thx for clearing this up
