Trouble diplaying Entityvalues in Radgrid

[Guenni]

Hello peepz,

 I'm using IdeaBlade DevForce as my middle-tier. But I'm founding troubles displaying the values of the records in the Radgrid. It's displaying to correct number of records, but "System.Data.DataRowView" as value for each column. Using a normal ASP.NET gridview I don't encounter any problems.
I also don't have any problems displaying the same EntityList in a RadTreeView.

Do you know what is causing this strange behaviour?
Thanks in advance

Without seeing your code, I would say that you are not binding the column to a field. Forexample:

<telerik:GridBoundColumn UniqueName="DataColumn"  DataField="BoundFieldName" HeaderText="Some Column Name"> </telerik:GridBoundColumn>

The DataField property tells the grid what dataset value to display in that column.

Thanks for listening!

Thanks for the reply,

When I drag and drop the Radgrid on my RadPane I can choose the datasourceID by selecting it from the smart tag.
This code is then generated:

<telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="MyContacts"
                                    GridLines="None" AutoGenerateColumns="False">
                                    <MasterTableView DataSourceID="MyContacts">
                                        <RowIndicatorColumn Visible="False">
                                            <HeaderStyle Width="20px" />
                                        </RowIndicatorColumn>
                                        <ExpandCollapseColumn Resizable="False" Visible="False">
                                            <HeaderStyle Width="20px" />
                                        </ExpandCollapseColumn>
                                        <Columns>
                                            <telerik:GridBoundColumn DataField="Gid" DataType="System.Guid" HeaderText="Gid"
                                                SortExpression="Gid" UniqueName="Gid" Visible="False">
                                            </telerik:GridBoundColumn>
                                            <telerik:GridBoundColumn DataField="NameOfContact" HeaderText="NameOfContact" ReadOnly="True"
                                                SortExpression="NameOfContact" UniqueName="NameOfContact">
                                            </telerik:GridBoundColumn>
                                            <telerik:GridBoundColumn DataField="Address" HeaderText="Address" ReadOnly="True"
                                                SortExpression="Address" UniqueName="Address">
                                            </telerik:GridBoundColumn>
                                             <telerik:GridBoundColumn DataField="City" HeaderText="City" ReadOnly="True" SortExpression="City"
                                                UniqueName="City">
                                            </telerik:GridBoundColumn>
                                            <telerik:GridBoundColumn DataField="PhoneNumber" HeaderText="PhoneNumber" ReadOnly="True"
                                                SortExpression="PhoneNumber" UniqueName="PhoneNumber">
                                            </telerik:GridBoundColumn>
                                            <telerik:GridBoundColumn DataField="Email" HeaderText="Email" ReadOnly="True" SortExpression="Email"
                                                UniqueName="Email">
                                            </telerik:GridBoundColumn>
                                           </Columns>
                                        <EditFormSettings>
                                            <PopUpSettings ScrollBars="None" />
                                        </EditFormSettings>
                                    </MasterTableView>
                                </telerik:RadGrid></td>

This is my DataSourceID:

 <cc1:AspDataSource ID="MyContacts" runat="server"
                        AdapterManagerAssemblyName="Contacts.Web.Model, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"
                        AdapterManagerTypeName="Guen.Contacts.Web.Model.MyContactsSelectorAdapterManager">
                    </cc1:AspDataSource>

I have a ASP.NET GridView in the same RadPane. Via the Smart Tag I selected the same DataSourceID And it displays the correct data.

I don't understand the error since I am binding the columns to their fields.

I'll appreciate your response.

Hi Guenni,

Unfortunately I cannot tell why this is not working only with the code snippet you have posted.

I suggest you to open a support ticket and create small working project with only the RadGrid using IdeaBlade DevForce as middle-tier. Thus I’ll be able to debug it locally and advice you how to proceed.

Hello guyz,

After some code changes I solved the problem.The problem was in the returned collection type.
In my Ideablade classlibrary I changed the return syntax.
So instead of

return this.PersistenceManager.GetEntities<MyContacts>(qry);

I added  .ToArray()  to return a simpler form of collection.

return this.PersistenceManager.GetEntities<MyContacts>(qry).ToArray();

Thanks for your feedbacks anywayz.
