DataConext binding for my RadContextMenu is being ignored. My menu is defined like this:

<UserControl.Resources>
    <telerik:RadContextMenu x:Key="LimbContextMenu" DataContext="{Binding SelectedLimb}" >
        <telerik:RadMenuItem Header="Expand" Command="{Binding ExpandItemCommand}" />
        <telerik:RadMenuItem Header="Expand to book" Command="{Binding ExpandToBookCommand}" />
        <telerik:RadMenuItem Header="Collapse" Command="{Binding CollapseItemCommand}" />
        <telerik:RadMenuItem Header="Collapse all" Command="{Binding CollapseAllCommand}" />
        <telerik:RadMenuItem Header="Jump to home" Command="{Binding JumpToHomeCommand}"
                             Visibility="{Binding JumpToHomeCommand.IsSupported, Converter={StaticResource BooleanToVisibilityConverter}}"/>
    </telerik:RadContextMenu>
</UserControl.Resources>


It works if I define it like this:
<UserControl.Resources>
    <telerik:RadContextMenu x:Key="LimbContextMenu"   >
      <telerik:RadContextMenu DataContext="{Binding SelectedLimb}">
        <telerik:RadMenuItem Header="Expand" Command="{Binding ExpandItemCommand}" />
        <telerik:RadMenuItem Header="Expand to book" Command="{Binding ExpandToBookCommand}" />
        <telerik:RadMenuItem Header="Collapse" Command="{Binding CollapseItemCommand}" />
        <telerik:RadMenuItem Header="Collapse all" Command="{Binding CollapseAllCommand}" />
        <telerik:RadMenuItem Header="Jump to home" Command="{Binding JumpToHomeCommand}"
                             Visibility="{Binding JumpToHomeCommand.IsSupported, Converter={StaticResource BooleanToVisibilityConverter}}"/>
      </telerik:RadContextMenu>
    </telerik:RadContextMenu>
</UserControl.Resources>

But this version displays a menu within a menu.

How can I get DataConext assigned on the outer menu?

Hi!

Is it possible to style the BusyIndicator as a regular progressbar with progress indicator and a custom text under it?
Even better if I could style it as a circular progressbar with custom text under it.

For now I only manage to change the color of the spinning wheel.

I have the AutoExpandItems property set to true on my RadTreeListView and it works great on the initial load. However after I change the RadObservableCollection it does not properly autoexpand and only some rows show up until I force a refresh on the screen.
My two use cases are
Changing or deleting an object in the observable collection,
Clearing the collection and then calling AddRange.

Let me know if this is unclear or you need more information.
Thank you

Hi,

I am having a problem getting the column totals updating after a cell has been edited in a RadGridView.
The columns are all (bar one) generated at runtime in the code behind (not MVVM).

My XAML;

<telerik:RadGridView   Margin="6" 
                                                   AutoGenerateColumns="False"
   x:Name="dgProducts" 
                                                   RowIndicatorVisibility="Collapsed"
   SelectionUnit="Cell" 
                                                   IsSynchronizedWithCurrentItem="True"
   VerticalGridLinesBrush="#CCC"
   HorizontalGridLinesBrush="#CCC" 
                                                   CanUserInsertRows="False"
   CanUserResizeRows="False" 
                                                   CanUserDeleteRows="False"
   ItemsSource="{Binding PromotionVolumes}" 
                                                   RowHeight="25"
   IsFilteringAllowed="False" 
                                                   ShowGroupPanel="False"
   IsReadOnly="{Binding CurrentPromotion.IsReadOnly}" 
                                                   ScrollMode="RealTime"
                                                   Loaded="dgProducts_Loaded"
   telerik:StyleManager.Theme="Transparent" 
                                                   CanUserResizeColumns="True" 
                                                   ShowColumnFooters="True" 
                                                   CellEditEnded="dgProducts_CellEditEnded"
                                                   CanUserFreezeColumns="False"
                                                   >
                                <telerik:RadGridView.Columns>
                                    <telerik:GridViewDataColumn Header="Product Name"
                                        DataMemberBinding="{Binding Path=Product.DisplayName}"
                                       Width="170" IsReadOnly="True">
                                        <telerik:GridViewDataColumn.AggregateFunctions>
                                            <telerik:CountFunction Caption="Count: " />
                                        </telerik:GridViewDataColumn.AggregateFunctions>
                                    </telerik:GridViewDataColumn>
                                     
                                </telerik:RadGridView.Columns>


I generate the columns, one for each item in an array of data;

          var b = new Binding(string.Format("Measures[{0}].RawValue", i));
                   var column = new GridViewDataColumn
                       {
                           DisplayIndex = i + existingColumnCount,
                           UniqueName = (i + existingColumnCount).ToString(),
                           Header = measures[i].Name,
                           DataMemberBinding = new Binding(string.Format("Item[{0}].Value", i)),
                           MinWidth = 90,
                           IsReadOnlyBinding = new Binding(string.Format("Item[{0}].IsReadOnly", i)),
                           Tag = new Binding(string.Format("Item[{0}].RawValue", i))
                       };

                   if (measures[i].IsCalculate)
                   {
                       column.DataMemberBinding.Mode = BindingMode.TwoWay;
                       column.DataMemberBinding.UpdateSourceTrigger = UpdateSourceTrigger.Default;

                       var sf = new SumFunction() { Caption = "", SourceField = b.Path.Path, SourceFieldType = typeof(decimal), ResultFormatString = "{0:N0}" };
                       column.AggregateFunctions.Add(sf);
                       column.AggregateFunctions.Add(aggregate);
                   }

                   grid.Columns.Add(column);


When cell editing happens I call;

      private void dgProducts_CellEditEnded(object sender, GridViewCellEditEndedEventArgs e)
       {
           this.dgProducts.Items.CommitEdit();
           this.dgProducts.CalculateAggregates();
       }



Ordering the grid has no effect on the footer totals either.

I have seen other posts on the forums going back to 2009 and apparently this has been fixed?
What am I missing?


cheers

Hi,

we add some custom connections to our shapes.

var outConnector = new InOutConnector() { Offset = new Point(0.5, 1), Direction = InOutConnector.eDirection.drOut, Name="StartConncetor"};                   
NewShape.Connectors.Add(outConnector);
NewShape.UseDefaultConnectors = false;

Works fine, but how do i edit the TargetCapType in here?

Thanks a lot
Best Regards

Hi,

I have been reading the resources and forum posts but I can't seem to be able to bind a TextBlock in my TrackBallInfoTemplate to a field on the DataItem object.

The following is the TrackBallInfoTemplate:
    <chartView:BarSeries.TrackBallInfoTemplate>
           <DataTemplate>
             <StackPanel Orientation="Horizontal">
               <TextBlock Text="{Binding DataPoint.Value}" FontWeight="Bold" />
               <TextBlock Text=":" FontWeight="Bold" />
               <TextBlock Text="{Binding DataPoint.DataItem.Name}" FontWeight="Bold" />     
</StackPanel>
           </DataTemplate>
         </chartView:BarSeries.TrackBallInfoTemplate>

The following is a definition of the class containing the data which is used to display the bar chart:
public class CategoryData
{
  public string Name { get; set; }
  public double Value { get; set; }
  public string Category { get; set; }
}

On the Bar Series definition in XAML the CategoryBinding is set to the "Category" field and the ValueBinding is set to "Value".

The graph displays but only the DataPoint.Value field is bound in the TrackBallInfo template. The other "Name" field does not appear.

According to the UI WPF API doc the "DataItem" field should contain "the original data item".

Ref:
http://www.telerik.com/help/wpf/p_telerik_windows_controls_charting_datapoint_dataitem.html

Am I missing something fundamental here? I am using Telerik.Windows.Controls.Chart version 2013.3.1204.40.

Thanks in advance,

Rob

I would like to display the validation error in the tooltip of a radgridview cell so when the user hovers over the cell the validation message will be displayed when the grid's RowIndicatorVisibility="Collapsed". I can see the error when hovering over the right top corner of the cell but that is very small and our users aren't sophisticated. I've tried creating a style but its not working.

Thank you for your help.

Hi,

I'm on .Net 4.0 and I use Telerik V2014.1.331.40 and I would like to know how I can access the RadWatermarkTextBox inside the control? For my scenario, I need to do some manipulation on the text inside the RadWatermarkTextBox.

Thank's
