So, i have radGridView with child 
  <telerik:RadGridView x:Name="radGridView" Grid.Row="5" Grid.ColumnSpan="2"  CanUserFreezeColumns="False" ItemsSource="{Binding ParentCollection}" IsFilteringAllowed="False" AutoGenerateColumns="False" ShowGroupPanel="False" IsReadOnly="True">
                <telerik:RadGridView.ChildTableDefinitions>
                    <telerik:GridViewTableDefinition/>
                </telerik:RadGridView.ChildTableDefinitions>
                <telerik:RadGridView.Columns>
                    <!--some columns -->
                </telerik:RadGridView.Columns>
                <telerik:RadGridView.HierarchyChildTemplate  >
                    <DataTemplate>
                        <telerik:RadGridView x:Name="nestedRadGridView" CanUserFreezeColumns="False" AutoGenerateColumns="False" ItemsSource="{Binding ChildCollection}" IsFilteringAllowed="False" ShowGroupPanel="False" IsReadOnly="True">
                            <telerik:RadGridView.Columns>
                     <!--some columns -->
                            </telerik:RadGridView.Columns>
                        </telerik:RadGridView>
                    </DataTemplate>
                </telerik:RadGridView.HierarchyChildTemplate>
            </telerik:RadGridView>

need to hide expander of parent grid in rows which have empty child collection. Where i can set style of this togglebutton, tried HierarchyExpandButtonStyle but seems like my style is not applied.

Is it possible to zoom the RadMap control so it shows a rectangular area that the user has selected by drawing a rectangle over it?

That is, the user:

1. Pushes the left mouse button down, but does not lift it up, at one corner of the area which they wish to zoom.
2. Drags the mouse to the opposite corner.  A drag rectangle is drawn showing the area that will be displayed when they release the mouse button.
3. Releases the left mouse button when they have selected the area they are interested in viewing.

At that point, the map is centered on the point in the middle of the rectangle they drew and the zoom level is changed to include the area they selected.

If the control itself doesn't have this functionality, can it be implemented using custom code?

You have a beautiful Tool bar on some of your examples of the Spreadsheet.  However, after looking into it, it is about 2000 lines of XAML.  I figure the chances of a good copy/past of the example is next to zero... especially when you have icons referenced that are not in my project.

Can you point me to a working copy of your example with this awesome toolbar so I don't need to invent the wheel? 

I appreciate your help,
Joel.

We were previously using a third-part mapping solution.  We are now developing our own in-house tile server using OpenStreetMaps .  I have to modify my application so it uses the in-house tile server.

My application will have an application setting that will be the base URL for the tile server.  I've replaced the third-party's WPF map control with a RadMap and I've added an OpenStreetMapProvider to my program, but I can't find how to change the URL that the provider uses to query the tile server.  How do I do this?

I'm using UI for WPF Q3 2013.  I can upgrade to a later version if I have to, just let me know.

Hello,

I would like to set IsFilterable="false" on all my columns. I can't seem to do this as I am not specifying my columns as Autogeneratecolumns="true". How can I turn off the filtering in this case please?

Thanks.

Hi,

I was wondering if there was a way to determine which points in a series are currently visible on a chart? The sort of thing I am looking for is a IsVisible property which is updated as you zoom/pan the chart.I have had a look and I can't see anything. Is there an easy way to achieve this?

Thanks,

Steven

Hi There

1. Can you share C# code for implementing VisualizationLayer.VirtualizationSource ,i.e I wish to create Virtualization layer object at runtime, define and add MapShapeDataVirtualizationSource AsyncShapeFileReader  in MapShapeDataVirtualizationSource, and 
setting its source to URI shapefile.

2. How many Virtualization layers can i add to radMap.

3. What is the maximum size of shapefile in MB which radMap WPF engine can render without UI responsive issue.

4. I have some 3000 shapefiles of size less than 5 KB.Should i add them all in one Virtualization layer or can load each of them in individual Virtualization layers.Kindly advice.

Thanks In Anticipation.

Hi,

i bind an ObservableCollection to a RadGridView.


xaml:
Now i want to sort the GridView


The Problem ist, that the GridViewDataColoumn is a string and the sorting works, but in a wrong way for example:

08.11.2014
09.11.2014
10.10.2014
11.11.2014

The Date 10.10.2014 should be the first one. How can i solve this?

Thanks
Best Regards

I have a WPF application. I've set the theme of my RadBusyIndicator to Windows8Touch with the below code in app.xaml using the code below.

<Application.Resources>
<Style TargetType="telerik:RadBusyIndicator" >
<Setter Property="telerik:StyleManager.Theme" Value="Windows8Touch"/>
</Style>
</Application.Resources>

I show the indicator by setting and IsBusy property in my viewmodel. Everything looks and works great until the very end. About 1 second before the indicator goes away (IsBusy=false) the theme turns from Windows8Touch to Office_Black (the swirling orange donut). It should not change!

What could be the problem?

Thanks,
Mark
