Hi,

Is it possible to do these two things with TabControl (TabOrientation="Vertical" and TabStripPlacement="Left")

1) all TabItem headers to occupy all available space. (ex, if tabControl's Height is 500, and we have 5 TabItems, then each TabItem should have Header.Height = 100. I am using below template to make TabItem;'s header wider, but I am setting the Height explicitly.

<DataTemplate x:Key="tabItemTemplate">

<Grid Height="100">

<TextBlock Text="{Binding Mode=OneWay, Converter={StaticResource enumConverter}}" VerticalAlignment="Center"/>

</Grid>

</DataTemplate

>



<telerik:RadTabControl ItemsSource="{Binding Source={x:Static data:ActivityType.Production}, Converter={StaticResource enumWithoutNoneConverter}}"

                       ItemTemplate="{StaticResource tabItemTemplate}"

                       SelectedItem="{Binding SelectedType}"

                       TabOrientation="Vertical"

                       TabStripPlacement="Left" />

2) I would like to set the Content of each TabItem to null (Nothing). Currently it is displaying the same text as Header does, only without converter. I don't want it to display anything, I just need TabControl;s headers visible.

Regards,
Goran

SelectAll

I was hoping to implement SelectAll functionality when the user double clicks in the cell that is to the left of the first column and above the first row.

I tried using hittesting to detect when the user clicks there, but didn't have any luck since it wasn't coming up as a valid row or column.

Is is possible to do this?

BringItemIntoView

Hi,

I'm using RadControls for WPF (version 2012.1.326.40), and my question is about the RadTreeView.
I want to select by code a specific item even if all nodes of the treeview has not been generated.
My treeview is using the virtualization mode, so the items are not generated until the node is expanded.
How can I select an item ? If I explore the nodes, I have only the generated nodes.
And I can't use the BringPathIntoView method, because my nodes have different types so it's impossible for me to use the property TextSearch.TextPath.
Do you have any solutions ?

Disallow Moving Tasks

Hello,

It seems that on all of your examples, the gantt-tasks can be moved and resized on the fly. How can I prevent this? I already have "isManipulationEnabled" set to false.

Thanks,

Custom Appointment class

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
