Hello there,
Do the gridview support making a six level hierarchy in an easy way?
Right now I'm setting my top data set as ItemsSource and then do a lot of child table definitions. To be able to remove GroupPanel and ColumnHeaders in my child nodes I'm listening on the DataLoading event casting the sender to a GridViewControl. For getting all the child column I have set the AutoGenerateColumns property to true. But I need to remove some of them so I also listening for AutoGeneratingColumn event. Doing this seems a little bit odd!
Another question is if I'm able to update the data at the bottom node in the gridview from a database without destroying the expanded hieararch made by the user?
Am I correct in my assumption that the gridview only support a two level hierarchy in a good manner.
Best wishes from Johan

How i can solve this problem? How i can use custom class for display position on Radmap control? I don't want use buffer object list =(

Hello all.
I'm working on stacked bar and i have one question about negative values.
Is it possible to show them on chart? Is it supported by <telerik: RadChart> control?
I have 5 vertical bars with 5 segments. See attached image, please.
You will be able to see that grey part from first bar is missing.
that one has negative value.
Is there any way / property which says to graph that it must be moved a little bit to the top and to show segnemt with negative value?

Hello all.
I have a problem with chart data within stacked bar chart.
Some data is not visible.
ItemSource of chart is List<decimal[5]>.
Image is attached.
Each column contains segments woth values from 30-70 from bottom to the top.
Bottom segments with value 30 are not visible at all.
I put AxisY.AutoRange to false and AxisY.MaxValue to 300 (sum of all segments from one solumn is 250).
Could you please help me about this?
Thanx in advance.

Hi ... I have a child grid for which I would like to show the IsExpandable button only if there is data in the objects child collection. I have tried the following XAML
<Style TargetType="{x:Type Controls:GridView.GridViewRow}">
<Setter Property="IsExpandable" Value="{Binding DeviceBehaviours.Count, Converter={StaticResource IntegerToBooleanConverter}, Mode=OneWay}" />
</Style>
The converter returns a boolean if the child collection has a count. This collection is asynchronous and returns a only result after the RowLoaded event has already run.
Weirdly this same Xaml works for the Expanded property.
Hope you can help

i have got a combobox which has set the RadComboBox.ItemTemplate to a combined string
<telerik:RadComboBox x:Name ="blah" HorizontalAlignment="Left" Margin="0,26.04,0,0" VerticalAlignment="Top" Width="167.54" d:LayoutOverrides="HorizontalAlignment" ItemsSource="{Binding Source={StaticResource respondentViewSource}}" >
so how can i have a search text area that actually searches the "displaymember" or "itemtemplate"
i think it's to do with telerik:TextSearch.TextPath, but i don't what value is expected in that attribute.
