RadGridView does not work properly under Silverlight 3 + RIA Services

[Ariel Ben Horesh]

Hi

I have been trying out RIA Services walk through. (http://bit.ly/5w1LEu).

The walkthourgh uses the regular Sliverlight grid. I've tried to change it to use the Teleric one.

When using the code-behind to populate the grid like this, it appears to work.

  this.dataGrid1.ItemsSource = _OrganizationContext.Employees;

But when I'm using the DomainDataSource as specified later on the walkthourgh, no Items are populated into the grid. Note that it is working for the regular Silverlight Grid.

Possibly a bug?

Hello Ariel Ben Horesh,

Could you please take a look at our online example RIA Services with Domain Data Source. Is your project configured in the same way? Here is part of the code that you can see in the example:

<Examples:GridViewExample x:Class="Telerik.Windows.Examples.GridView.DomainDataSource.Example"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:riaData="clr-namespace:System.Windows.Data;assembly=System.Windows.Ria.Controls"
    xmlns:riaControls="clr-namespace:System.Windows.Controls;assembly=System.Windows.Ria.Controls"
    xmlns:data="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data"
    xmlns:Examples="clr-namespace:Telerik.Windows.Examples"
    xmlns:telerik="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView"
    xmlns:e="clr-namespace:ExamplesWeb">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition />
            <RowDefinition Height="30" />
        </Grid.RowDefinitions>
        <riaControls:DomainDataSource x:Name="DomainDataSource1" AutoLoad="True" QueryName="GetCustomers">
            <riaControls:DomainDataSource.DomainContext>
                <e:NorthwindDomainContext />
            </riaControls:DomainDataSource.DomainContext>
            <riaControls:DomainDataSource.FilterDescriptors>
                <riaData:FilterDescriptorCollection LogicalOperator="Or" />
            </riaControls:DomainDataSource.FilterDescriptors>
        </riaControls:DomainDataSource>
        <telerik:RadGridView x:Name="RadGridView1" ItemsSource="{Binding Data, ElementName=DomainDataSource1}"
                             Filtering="RadGridView1_Filtering" IsBusy="{Binding IsLoadingData, ElementName=DomainDataSource1}" />
        <data:DataPager x:Name="DataPager1" Grid.Row="1" PageSize="10" Source="{Binding Data, ElementName=DomainDataSource1}" />
    </Grid>
</Examples:GridViewExample>

I hope this helps.

Well I am aware of the sample.

But still it doesn't work.

Check out this image: http://twitpic.com/sws2m

The grid is wired up like in the sample, There is data in the DomainDataSource, as you can see that the DataPager is properly working.

But no columns and no data.

Apperciate some help.

Sure thing.

Note that it is the same sample you get when you finish : http://code.msdn.microsoft.com/RiaServices/Release/ProjectReleases.aspx?ReleaseId=2387

Hi Ariel Ben Horesh,

We have identified the problem. There was bug with version 2009.3.1103.1030 of RadGridView and the new beta of WCF RIA Services. You should upgrade to 2009 Q3 SP1 (2009.3.1208.1030) (released a couple of days ago) and everything will work as expected.
