Hello @all,

all me entities are using the same base class EntityBase.

Is it possible to create my own Appointment class which inherits from EntityBase, instead of youse the Appointment class of telerik?
I chouldn't find an Interface of Appointment, only a abstract base class.

In other words:
I like to use the RadScheduler with my own Appoinment class.

Thank you,
Manuel

Map Modes with Custom Provider

Hello,

I have created a custom provider with my own tiles.
Now,I´d like to create three map modes with different tiles. (Roal, Aerial.. as Bing or Google)
I want to show my modes on the toolbar so the user could change view easily.
How can I do that? I have no idea where I have to indicate the different modes. I have my TilesProvides created like that

Public Sub New(ByVal tileLocation As String, ByVal tileUri As String)

MyBase.New()

Dim source As New NavteqMapSource(tileLocation, tileUri)

Me.MapSources.Add(source.UniqueId, source)

End Sub

But I need three different Uris for each MapMode. Do I have to create three different providers?
If so, How can I add this providers to the toolBar?
Thank you very much,

Esther

Change the QueryName of a RadDataServiceDataSource?

It seems that I can supply a {Binding} for the QueryName of a RadDataServiceDataSource, but if I do, it changes the way the data source gets queried. Using the "hard-coded" approach, the query honors the page size specified by the data source ($top=n), but binding to a property of a ViewModel that contains the QueryName causes the query to request ALL items.

What I'm trying to craft is a simple UI that lists the tables (queries) in the data source in a ListBox, and causes the RadGridView/RadGridPager to display (and page through) the data for the table selected in the ListBox.

I had assumed that data binding the QueryName would be the WPF way to do this. What am I missing?

RadComboBox causes memory leak in WPF

I have used RadComboBoxes inside a Grid in my WPF application as shown below. 

<tk:RadComboBox Grid.Row="3" Grid.Column="3" Style="{StaticResource DropDown}" x:Name="cmbColor" Height="25" Margin="5,5,5,5" DropDownOpened="cmbColor_DropDownOpened"
IsEditable="False" SelectedValue="{Binding PR_COLOR}" MaxWidth="250"
ItemTemplate="{StaticResource DropDownCodeMeaning}"  />








I am binding the data to the combo box when the user clicked on the combo box to select an item from it.

I have used the  event "DropDownOpened" to bind data to this combo box.



Below shown is the code behind.



// set the dropdown list for a combobox to all entities for a business object
  private void SetDropDown<BusObj, BusEntity>(RadComboBox cmb, ref BusObj busobj)
      where BusObj : BusinessObject<BusEntity>, new()
      where BusEntity : BusinessEntity, new()
  {
      if (busobj == null)
      {
          busobj = new BusObj();
      }
      if (cmb.ItemsSource == null)
      {
          var RecordList = busobj.GetAllEntities();
          if (RecordList.Count > 0)
              RecordList.ApplySort("SortKey", ListSortDirection.Ascending);
          cmb.ItemsSource = RecordList;
 
      }
  }



After sets the Items Source for the combo box, the memory increases rapidly. Anyone knows why this happens? 

Please help me. I am using the telerik version 2010.1.603.35.



Thanks in advance,

RadGrid + SortDescriptors

hi,

i'm using wpf 2012 Q1 SP1 and VisualBasic 2010. I'm using a RadGridView bind to a mvvm. After closing the line "telerik:ColumnSort..." with "/>" my VisualBasic is killed. Nothing works any more. I have to kill VS with the TaskManager.

<telerik:RadGridView.SortDescriptors>

<telerik:ColumnSortDescriptor Column="{Binding Columns[\Country\], ElementName=RadGridView1}" SortDirection="Ascending" />

</telerik:RadGridView.SortDescriptors>

Is this a known Problem?

thanks
Regards
Rene

Can an additional y-axis share "0"

Hello,
Can an additional y-axis on the right be set up so that it's 0 value lines up with the standard y-axis 0 on the left? On the standard axis I am plotting something like profit vs. expenses with the yellow line displaying the net difference. On the additional y-axis I am displaying a grand total on a significantly larger scale. Since the grand total is never negative the additional y-axis has 0 at the bottom but ideally I would like it's 0 to line up with the standard axis 0. Thanks much in advance!

Q2 Upgrade Issue

Hello,

I Just upgraded my project to Q2, and now the vertical divider between the columns table and the tasks no longer is movable (in other words, the width of the column table is fixed). Is there a way to specify the width of the column table (apart from changing individual column widths)? Also, how can I make that slider movable again?
Thanks,

Eric

Chart interactivity not working

Hi,

I am working with the telerik bar chart and pie chart. And by looking at an example I set the series interactivity as such:

For a bar chart:
DataSeries barSeries = modelDictionary[ChartType.Bar];
            barSeries.Definition.InteractivitySettings.HoverScope = InteractivityScope.Item;
            barSeries.Definition.InteractivitySettings.SelectionScope = InteractivityScope.Item;

For a pie chart:
DataSeries pieSeries = modelDictionary[ChartType.Pie];
            pieSeries.LegendLabel = "Pie Series";
            pieSeries.Definition = new PieSeriesDefinition();
            pieSeries.Definition.InteractivitySettings.HoverScope = InteractivityScope.Item;
            pieSeries.Definition.InteractivitySettings.SelectionScope = InteractivityScope.Item;
            pieSeries.Definition.InteractivitySettings.SelectionMode = ChartSelectionMode.Single;
The interactivity does not work when I do a mouse hover.
