[CLOSED] Wrong response when trying to use an ObjectDataSource

[alexp]

Hello,
first of all I want to greet everybody as this is my first post. And I also want to congratulate you on this great library.

So, what I am trying to do is the following:

Simple ext:GridPanel getting data from an ObjectDataSource (I must say this is my first proper test).
This is the ASP code:

        <asp:ObjectDataSource ID="ObjectDataSource1" runat="server" SelectMethod="GetGroups" TypeName="Group" OnSelected="ObjectDataSource1_Selected">
            <SelectParameters>
                <asp:Parameter Name="start" Type="Int32" />
                <asp:Parameter Name="limit" Type="Int32" />
                <asp:Parameter Name="sort" />
                <asp:Parameter Name="dir" />
                <asp:Parameter Name="count" Direction="Output" Type="Int32" />
            </SelectParameters>
        </asp:ObjectDataSource>

        <ext:Store ID="Store1" runat="server" AutoLoad="true" RemoteSort="true" DataSourceID="ObjectDataSource1" OnRefreshData="Store1_RefreshData">
            <AutoLoadParams>
                <ext:Parameter Name="start" Value="={0}" />
                <ext:Parameter Name="limit" Value="={3}" />
            </AutoLoadParams>
            <Proxy>
                <ext:DataSourceProxy />
            </Proxy>

            <Reader>
                
                <ext:JsonReader ReaderID="ID">
                    <Fields>
                        <ext:RecordField Name="Name" />
                        <ext:RecordField Name="Status" />
                    </Fields>
                </ext:JsonReader>
            </Reader>
        </ext:Store>

                                    <ext:GridPanel 
                                        ID="GridPanel1" 
                                        runat="server" 
                                        AutoExpandColumn="Name" 
                                        StoreID="Store1"
                                        Border="false">
                                        <ColumnModel ID="ColumnModel1" runat="server">
                                            <Columns>
                                                <ext:Column ColumnID="Name" DataIndex="Name" Header="Name" />
                                                <ext:Column ColumnID="Status" DataIndex="Status" Header="Status" />
                                            </Columns>
                                        </ColumnModel>
                                        
                                        <BottomBar>
                                            <ext:PagingToolBar 
                                                ID="PagingToolBar1" 
                                                runat="server" 
                                                PageSize="10" 
                                                StoreID="Store1" 
                                                />
                                        </BottomBar>
                                        <LoadMask ShowMask="true" />
                                    </ext:GridPanel>

and Group.GetGroups is a static method.
The AJAX call is triggered but the information I get back is empty.

My question is: what type should the data method return so that it is readable by the ext:Store object?

Hi alexp,

It can be any object which can be handled with reflection for getting properties.

What type return GetGroups?

May be you can post your example which we can run and test.

Try to handle LoadException event. May be error occurs during data retrieving.

Thanks for the very quick answer,
it turns out the bug was somewhere else.

And by the way, if works great if I return standard data types such as DataSet or DataTable.
