Hi Guys,

I have a WPF app which has a RadMap with 2 layers. The first layer is a dynamic layer which contains lots of MapPolygons loaded from shape files with the background colour set according to the metadata in the shape file. The second layer is an information layer with lots of MapPinPoints which sit on top of the shapes in the dynamic layer.

This app is going onto a ruggadised tablet and will be used in direct sunlight, and as such the users would like a good contrast between the text on the MapPinPoints and the MapPolygons they sit on top of. I've written the code to change the fonts and this works really well when I can get it to execute. The problem I have is trying to figure out when the dynamic layer has finished rendering so that it's .Items property actually has something in it and I can check which polygons a pinpoint falls into.
 
I have tried hooking into various events such as LayoutUpdated, SizeChanged, etc.. I even created my own event on the MapDynamicSource to notify me when the ItemRequest is complete, but the Items collection is still empty at this point...

Both layers change fairly regularly and so the Loaded event doesn't help me either because it only fires once.

If you need any more info please let me know, otherwise any help would be really appreciated.

Thanks,
Stuart

I'm using the latest version of the WPF controls and am trying to do a RadGridview->RadGridview drag and drop.  Unfortunately, all of the examples I've been able to find seem to be for a much older version of the Telerik tools, and contain references to properties that don't exist in the version I'm using.

Does anyone have a complete example (C#, ideally, but anything will do) that uses the current release of the Telerik controls showing how to drag and drop between two RadGridview controls?  Thanks.

Hi,

I would like to detect mouse click on each row in RadGridView. Here is my code sample:


The problem is that this event is never fired. I can change event to MouseRightButtonUp or even MouseEnter and it all works fine. Why i cannot subscribe to MouseLeftButtonUp?

Hi,

I am working on WPF.\ and we are using telerik controls in our project.

we are implementing Expand all rows functionalaity in Telerik radgridview . In our radgridview few rows has childgrid and if we are using expandallhierarchyitems() method then it is expanding all rows. My requirment is when i click on expand all button then it shoud expand only those rows which have child grid control.

Hello,

I am using the MVVM pattern.  I have a GridView on a usercontrol that has the datacontext set to a viewmodel.  The viewmodel contains an ObservableCollection of model objects that are bound to the ItemsSource of the GridView.  My GridViewDataColumn.Header properties are bound to some properties in the viewmodel and everything works as expected.  The Header values are genrated dynamically and dispalyed properly through the binding.  When I add a DataMemberBinding to a GridViewDataColumn and bind it to a property from the object collection, I get unexpected Header value.  The Header will display the value "SourceName".  This only happens when the SourceName property exists on the model object and a successful binding is created for the DataMemberBinding property.  If I put in a value such as SourceNameTest, the Header is displayed correctly.  Here is a snippet of one of the columns in question.  As you can see it is a very simple column definition.  Could you please help me understand if there is way to accomplish what I am trying to do.

<telerik:GridViewDataColumn DataMemberBinding="{Binding SourceName}" Header="{Binding SourceObjectHeader}" >
Thanks,

Jason

 

 

 

 

I have had installed the trial version of your WPF controls and then installed the licensed version but I am still getting the Trial message box.Is there anything I can do in order to get rid of this message box?

I'm using Entity Framework 4.0 and have a "Players" class.  Bone-stock, nothing added or changed, just as VS2010 generated it, which means it's an ObjectSet.

If, in my _Loaded event I do this:

• CollectionViewSource myCollectionViewSource = (CollectionViewSource)this.Resources["playersViewSource"];
• myCollectionViewSource.Source = this.DbContext.Players;

I can click to add a new row, update existing items, etc.  I can't click on row headers to sort them, though.


If I do this:

• myCollectionViewSource.Source = this.DbContext.Players.ToList();

Hello,

I was wondering if the WPF GridView has the same pinning functionality as the WinForms gridview documented here: http://www.telerik.com/help/winforms/gridview-rows-pinned-rows.html

I didn't see anything in the WPF samples and the WinForms code doesn't work for WPF.


Thanks,
Derek

Hi Telerik team,

Thanks for the reply. It's working now.

One final question I have right now, Please respond.

Can we measure the openstreemap means you click on some points and it draws a poly line and during that time it shows the length of that polyline in meters / feet.

Please let me know if it possible or not?

If you have some sort of sample code please pass over it.

Thanks for your help.
Vivek,

I have a RadRibbonComboBox in a RadRibbonTab in a RadRibbonBar.  Looks something like this:


I have defined three different Data Templates in the resources like this:


I want to use a specific Data Template for the EmptySelectionBoxTemplate depending on various conditions.  Therefore, I want to set the EmptySelectionBoxTemplate in code.  I have tried setting the template like this:


The resource is found, and appears to be set in the combo box, but the display does not get altered.  I also tried invalidating the property and visual state:


Invalidating did not help.  The combo box selection is -1, and if I set the EmptySelectionBoxTemplate in XAML, the box displays the message correctly.

What is the correct way to change this template in code?
