Hi,
Is it possible to add drag drop to dynamically added images or elements to a canvas and if yes how do you do it please?
Thanks

Hi,

I was wondering if there was any sample code for how to allow a user to drag a pin from outside of the map view onto the map view, thereby associating that location with the object where the pin was dragged from.

e.g. user drags pin from street address control A onto the map, A then gets set to the location under the pin point.

Thanks
Pete

Hi,
Thanks for the wonderful chart control provided from telerik. Is there a feature like dragging the chart area and datapoints gets updated depending on the drag. I tried with RadDrapDropManager but could not.

Using RadDragDropManager, i should drop the drag. that should not be the case for me...

Scenario:
1. RadChart holding queue with 1000 data points.
2. But the current chart view shows only latest 10 points.
3. If drag the chart area to left/right, then data points must get updated. (this must depend on drag sensitivity).
4. This is some thing like playing the chart area w.r.t to datapoints in the queue.
5. Should have an event warning me that i am at point 0 and point 1000 on the graph. (start and end of the queue).

Thanks,
Lakshman

Hi, 

I am getting an error when typing into the RadComboBox that states that it cant cast from type x to type y. The situation that we have is that the combo box is bound to a list of types that all implement a given interface but which do not necessarily share a common base type. The interface defines a property Description which is what we're actually binding to. If I use the combo box with the mouse and select from the list then all is fine, it is only when typing into the combo box that it blows up. Please see the attached stack trace for more info.

Thanks, Steve

Hello,

I have come across what I believe is a bug in the GridViewComboBoxColumn. The reason for this assumption is that I was able to take a working example of what I was trying to accomplish from this form (see http://www.telerik.com/community/forums/wpf/gridview/displaying-related-table-data.aspx for the attached working version) and reproduce the problem in my environment.

Let me stop to explain what it is I am trying to accomplish. The high level explanation is that I am trying to set the ItemSource property of the GridViewComboBoxColumn to the defaultview of a datatable I am operating on. The behavior is that no values are displayed in the column cells, but editing the column yields a combobox that is properly bound to the datatable.

This behavior can be reproduced with the following steps:

1) Grab the sample project that was provided by Pavel Pavlov of the Telerik team.
2) Convert the project to VS2010.
3) Run the project to make sure it is behaving as it should be.
4) Set the target framework to .NET framework 4.0 Client Profile.
5) Run the project to make sure it is behaving as it should be.
6) Remove all Telerik references.
7) Re-add Telerik references from RadControls for WPF 2010 SP2 (I have a trial license if that makes any difference; version number for assembies is 2010.1.603.35 if that helps).
8) Run the project. You will see that the TownID column is now full of blank cells.

Please let me know if this is a known issue and if/when you expect to be able to release a hotfix. Also, any workarounds you can think of that don't require me to rearchitecht all of my data storage objects would be appreciated.

Quick Start Notes:
    OS: Win XP SP3
    Application Type: WPF
    Target Framework: .Net Framework 4.0 Client Profile
    Language: C#.Net
    IDE: Visual Studio 2010
    Telerik Release Version: Q1 2010 SP2 (Trial License)
    My Telerik Assembly Version: 2010.1.603.35
    Sample (working) Telerik Assembly Version: 2010.1.309.35

Thank You,

Hello Telerik Team,

I Converted code VB to C#. In VB it is alreday tasted & worked perfectly but in C# Rebind is not working properly.

While loading window am setting like below:

  rgvSet.ItemsSource = DataModule.objSets;
  rgvOrders.ItemsSource = DataModule.objOrderList;
  rgvTour.ItemsSource = DataModule.objTourList;
  rgvTruck.ItemsSource = (from p in DataModule.objTruckList where p.Status == DataModule.Cons_Status_Available select p).ToList<clsTruck>();
  rgvTrailer.ItemsSource = (from p in DataModule.objTrailerList where p.Status == DataModule.Cons_Status_Available select p).ToList<clsTrailer>();
        rgvDriver.ItemsSource = (from p in DataModule.objDriverList where p.Status == DataModule.Cons_Status_Available select p).ToList<clsDriver>();

"rgv... " are RadgridView and all List are ObservableCollection. After doing such operation adding/removing/updating in collection am rebinding appropriate grid. Grid which having itemsource as LINQ query will not Rebind but Grid which have collection as Itemsource will rebind correctly.

What could be a reason? any idea?

Thanks...!!!

Hi,
In our application we have a requirement in which we want to show a tree hierarchy in expanded state, we should not able to collapse it and no expander be shown.
How can we do it using RadTreeView ?

Hello!
Assuming that I have 6 different SeriesMapping in a chart but in the chart's legend I want to show only 4 of them how should I do this??
I've tried to set their LegendLabel to null but this only puts the default "Series x" label in Legend which is not the desired behavior.

Thank you! 
Roxana
