Hi!
I use VirtualQueryableCollectionView in my project (WPF Q3 2010).
public MainWindow()
{
    InitializeComponent();
    
    OraContext ctx = new OraContext();
    var view = new VirtualQueryableCollectionView(ctx.OSTs) { LoadSize = 5 };
    DataContext = view;
}

I get error, when grouping in GridView

Unable to cast object of type 'Telerik.OpenAccess.Query.GroupKeyAccessT' к типу 'OpenAccessRuntime.DataObjects.query.Node'

Thank you.

I have a WPF radGridView populated with data.  There are 3 columns - "ID", "FirstName", and "LastName" for simplicity.

"ID" is a hidden column.  It's only there so I can reference the ID in code behind.

So the Grid is displaying FirstName and LastName.  In the interface, I have code-behind on the CellEditEnded event which is supposed to update the database with any changes in data.  The code is archaic still and I know there are validity checks that have to be added, etc., but my problem is I cannot obtain the ID of the row I'm in.  In this event, e is of type Telerik.Windows.Controls.GridViewCellEditEndedEventArgs

I'm trying to use e.Cell.ParentRow.Cells(0).ToString but that returns the value of the first visible cell.  Moreover, I don't want to use Cells(0), I'd rather use the cell name in case the index value changes - but this only takes index values.  I've tried going back to the grid itself using something like uxGRIDNAME.row(0)... etc but there doesn't seem to be any property that I can use to go to a specific row.  Moreover, "e" doesn't contain a rowindex anyway.  I'm baffled that this is so difficult to figure out - it seems like something that should be so simple.  I'm sure someone has some kind of insight here.  Thank you in advance!

Hi telerik,

I've created two custom filters for my RadGridView and everything works fine.
When I'm going to filter data with filter "A" and + filter "B". Only one filter is going to filter data.
I want to filter data by using two of them (filter A + filter B).
What should I do for that ?

thank you,
Julian

Dear Telerik,

RadPaneGroup inherited from ItemsControl and can contain a list of RadDocumentPane. I want to use RadDocumentPane as ItemTemplate of RadPaneGroup. The code is:

<t:RadSplitContainer>
    <t:RadPaneGroup ItemsSource="{Binding WorkflowItems}">
        <t:RadPaneGroup.ItemTemplate>
            <DataTemplate>
                <t:RadDocumentPane Header="{Binding Name}" Content="{Binding Workflow}">
                    <t:RadDocumentPane.ContentTemplate>
                        <DataTemplate>
                            <TextBlock Text="{Binding}" />
                        </DataTemplate>
                    </t:RadDocumentPane.ContentTemplate>
                </t:RadDocumentPane>
            </DataTemplate>
        </t:RadPaneGroup.ItemTemplate>
    </t:RadPaneGroup>
</t:RadSplitContainer>

There is no error when building and running. But the UI has problem. (See attached file)
http://www.telerik.com/ClientsFiles/235713_ui-problem.png

BTW: I just tried, use RadPane as ItemTemplate will cause the same problem.

I've got a recent problem:

My grid looks like this:

<telerikG:RadGridView x:Name="ExpositionFilterRules"
    AutoGenerateColumns="False" SelectionMode="Single"
    FontSize="14" AllowDrop="False" CanUserDeleteRows="False"
    CanUserFreezeColumns="False" CanUserInsertRows="False"
    CanUserReorderColumns="False" ShowGroupPanel="False"
    RowIndicatorVisibility="Collapsed" ScrollMode="Deferred"
    IsEnabled="True" IsReadOnly="False">
     
    <telerikG:RadGridView.Columns>
        <telerikG:GridViewDataColumn Header="{StaticResource Promotions_ExpositionRule_ExpositionType}" MinWidth="200">
                    <telerikG:GridViewDataColumn.CellTemplate>
                            <DataTemplate>
                                    <ComboBox ItemsSource="{DynamicResource ExpositionTypes}" SelectedItem="{Binding ExpositionType}"></ComboBox>
                            </DataTemplate>
                        </telerikG:GridViewDataColumn.CellTemplate>
        </telerikG:GridViewDataColumn>
    </telerikG:RadGridView.Columns>       
</telerikG:RadGridView>

Grid shows objects with filled values (in this case object's property is ExpositionType).  Everythig looks fine until grid is scrolled via vertical scrollbar. When row goes out of the visibility range null value is inserted into the object's ExpositionType property. 

I dont use GridViewComboBoxColumn because I want to edit values without switching grid into edit mode (it requires more clicks).

My question is: how to prevent grid from deleting my data when scrolled?

<telerikG:RadGridView x:Name="ExpositionFilterRules"

Hi,

Yesterday, I've faced with the situation that I can't set the value of the check box to my custom filter.

Well, take a look on that:

<CheckBox x:Name="myCheckBox"/>

<telerik:RadGridView.Columns>
<telerik:GridViewDataColumn>
           <CustomFilter:MyCustomFilter GetTheValueOfCheckBox={Binding ElementName=myCheckBox, Path=IsChecked}
        </telerik:GridViewDataColumn>
</telerik:RadGridView.Columns>
<telerik:RadGridView x:Name="myGrid">
</telerik:RadGridView/>

In code behind of the MyCustomFilter I registered my DependencyProperty.

I have to addmit, that we use MVVM and the grid is a view part only without codebehind.

How can I handle this issue ? 

Thank you in advance,
Julian

Hello,
Setting the content of a label to A_B_C_D for instance renders the text as AB(underlined)_C_D (please see the attached screenshot).

The TreeListView control behaves exactly the same, so I can only assume this applies to all the controls.

How do I make sure my text gets displayed correctly?

Thanks,
