Hello,
I have a gridview with a content that should be filtered by the selected item of a combobox.

When I change the selected item in the combo, the content of my grid is updated.

This is working when I use a combobox but not when I use a radcombobox.

Both comboboxes are declared the same way.
Maybe I'm missing something...

The working combobox:

<ComboBox DisplayMemberPath="ChannelName"

ItemsSource="{Binding ElementName=channelDetailDomainDataSource, Path=Data}">

</ComboBox>

The non working radcombobox:

<telerik:RadComboBox DisplayMemberPath="ChannelName"

ItemsSource="{Binding ElementName=channelDetailDomainDataSource, Path=Data}" >

</telerik:RadComboBox>

Here is the domaindatasource:

<riaControls:DomainDataSource AutoLoad="True" d:DesignData="{d:DesignInstance my:ChannelDetail, CreateList=true}" Height="0" LoadedData="channelDetailDomainDataSource_LoadedData" Name="channelDetailDomainDataSource" QueryName="GetChannelDetailsQuery" Width="0">

<riaControls:DomainDataSource.DomainContext>

<my:AkDomainContext />

</riaControls:DomainDataSource.DomainContext>

</riaControls:DomainDataSource>

The linked domaindatasource with its parameter:

<riaControls:DomainDataSource AutoLoad="True" d:DesignData="{d:DesignInstance my:GridList, CreateList=true}" Height="0" Name="gridListDomainDataSource" QueryName="GetGridProgramListsQuery" Width="0" LoadedData="gridListDomainDataSource_LoadedData">

<riaControls:DomainDataSource.QueryParameters>

<riaControls:Parameter ParameterName="channelID" Value="{Binding ElementName=channelDetailDomainDataSource, Path=Data.CurrentItem.ChannelID}" />

</riaControls:DomainDataSource.QueryParameters>

<riaControls:DomainDataSource.DomainContext>

<my:AkDomainContext />

</riaControls:DomainDataSource.DomainContext>

</riaControls:DomainDataSource>

And finally my grid:

<telerik:RadGridView CanUserFreezeColumns="False" FrozenColumnCount="0" ItemsSource="{Binding ElementName=gridListDomainDataSource, Path=Data}" AutoGenerateColumns="False" Name="grdGridLive">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Start}" Header="Début" Width="2*" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding Title}" Header="Nom du Programme" Width="2*" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding GenreName}" Header="Genre" Width="*" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding Path=Duration, Converter={StaticResource millisecondsTimeConverter}}" Header="Durée" Width="*" />

</telerik:RadGridView.Columns>

</telerik:RadGridView>

Maybe the rad combo need more parameters to do the same work?

Thank you for your help.

Hi John,

Thank you for contacting us.

Could you please share with us which version of the controls you are using?
Please upgrade to the latest official release - Q2 2010 SP1 and contact us if you still experience the issue.
The RadComboBox doesn't need any other parameters to work, so if you have this problem again after the upgrade, could you please send us a sample project, which we can run here locally. In that way we will be able to assist you in the best manner.

Best wishes,
Konstantina
