I wanted to select my E:\ Drive in OpenFolderDialog and selected it on the left side, like I always do in Windows default dialogs.

Sadly this does not seem to be possible with your OpenFolderDialog. Instead, I had to click This Computer on the left side and select the drive on the right side.

Could this be changed? Is there maybe an option for it I didn't saw?

Thanks

Hi,

I create a program to modelize data. I use Save() function with serialize item (like TableShape Demo)

this my serialize function for my TableGraphSource :

public override void SerializeNode(NodeViewModelBase node, SerializationInfo info)
{
    base.SerializeNode(node, info);
 
    if (node is INodeSerializable)
    {
        info = (node as INodeSerializable).Serialize(info);
    }
}

each model have a Serialize method with his own parameters to serialize

It's the same for Deserialize TableGraphSource :

public override NodeViewModelBase DeserializeNode(IShape shape, SerializationInfo info)
       {
           NodeViewModelBase node = null;
           if (shape is TableShapeMulti)
           {
               var table = new TableModelMulti();
               node = table.Deserialize(info);
           }
           else if (shape is TableShape)
           {
               var table = new TableModel();
               node = table.Deserialize(info);
           }
           else if (shape is ShapeShape)
           {
               if (null != info["Content"])
               {
                   switch (info["Content"].ToString())
                   {
                       case "Controls.Entity.Models.ShapeModel":
                           var _sm = new ShapeModel();
                           node = _sm.Deserialize(info);
                           break;
                      ...
                       default:
                           var shapeModel = Activator.CreateInstance(Type.GetType(info["Content"].ToString()));
                           if (shapeModel is ShapeModel)
                               node = (shapeModel as ShapeModel).Deserialize(info);
                           break;
                   }
               }
 
           }
           else
           {
               var row = new RowModel();
               row.Deserialize(info);
               node = row;
           }
           if (null != node)
           {
               if (info["Position"] != null)
                   node.Position = Utils.ToPoint(info["Position"].ToString()).Value;
 
               if (info[this.NodeUniqueIdKey] != null)
               {
                   var nodeUniquekey = info[this.NodeUniqueIdKey].ToString();
                   if (!this.CachedNodes.ContainsKey(nodeUniquekey))
                   {
                       this.CachedNodes.Add(nodeUniquekey, node);
                   }
               }
           }
 
           return node;
       }

 

Saving is OK and Reloading is OK (all data are correctly affected) but i have a problem with ContainerShape : Width, Height, Position (X,Y) properties are not binding  anymore between shape and model when i reload diagram.

I use styleSelector to link shape with model (my app is based on TableShape demo for code structure)

Can you help me please ? Thanks

I'm trying to get myself introduced into using the RadChartView here and I'm working from your demos on the matter but when I try building I get this compiler error: 

message: The type or namespace name 'Windows' does not exist in the namespace 'Spike.Telerik' (are you missing an assembly reference?)
file: GvsDefectsChartControl.xaml 19 26
project: Spike.Telerik.RadChartView

Apparently there's an assembly that needs to be referenced but the message isn't gibing me much of a hint on which one.
Also, on the whole, I think your demos are lacking in this area. None of the XAML examples I've seen includes the namespace declarations, just the rendered tags. Those all include custom (Telerik) namespaces. Fortunately I have Jetbrains Resharper to help me set up the correct namespace declarations but I'm still stuck with the above error.

This is my complete XAML:

<UserControl x:Class="Spike.Telerik.RadChartView.MyTestChartViewControl"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
             xmlns:chart="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Chart"
             xmlns:chartView="http://schemas.telerik.com/2008/xaml/presentation"
             mc:Ignorable="d"
             xmlns:GVS="clr-namespace:Spike.RADChart.GVS"
             d:DesignHeight="300" d:DesignWidth="300">
     
    <UserControl.Resources>
        <GVS:MyViewModel x:Key="_testVM"/>
    </UserControl.Resources>
     
    <Grid DataContext="{StaticResource _testVM}">
             
        <chart:RadCartesianChart >
 
            <chart:RadCartesianChart.HorizontalAxis>
                <chartView:DateTimeCategoricalAxis LabelRotationAngle="50" LabelFormat="HH:mm"/>
            </chart:RadCartesianChart.HorizontalAxis>
 
            <chart:RadCartesianChart.VerticalAxis>
                <chartView:LinearAxis />
            </chart:RadCartesianChart.VerticalAxis>
 
            <chart:RadCartesianChart.Series>
                <chartView:SplineSeries
                    ItemsSource="{Binding Path=Data}"
                    CategoryBinding="Time"
                    ValueBinding="Value"
                    />
 
            </chart:RadCartesianChart.Series>
             
        </chart:RadCartesianChart>
         
    </Grid>
</UserControl>


I would appreciate any help.
Thanks

Does anybody know what's the right way to remove the radwindow header from the tab navigation cycle?

 

<telerik:RadWindow IsTabStop="False">

is permitted but doesn't have the desired effect.

 

 

<telerik:RadWindow>

     <telerik:RadWindow.Header
        IsTabStop="False"
        >
        Manage Styles
    </telerik:RadWindow.Header>

Is not permitted... "Attribute is not allowed in property element"

 

 

Thanks

Hi, i'm using LinearAxis for TimeSpan values. Minimum = 1 second and Maximum - maybe 1000 days.

For values - ScatterLineSeries. In test with perfomance troubles ~500 points.

        <telerik:RadCartesianChart Zoom="10,1"

            Name="_chart" Palette="{StaticResource ScatterCustomPalette}">
            <telerik:RadCartesianChart.HorizontalAxis >
                <telerik:LinearAxis  IsStepRecalculationOnZoomEnabled="False" LabelFitMode="Rotate">
                    <telerik:LinearAxis.LabelTemplate>
                        <DataTemplate>
                            <TextBlock Text="{Binding Converter={StaticResource LinearAxisTimeSpanConverter}}" />
                        </DataTemplate>
                    </telerik:LinearAxis.LabelTemplate>
                </telerik:LinearAxis>
            </telerik:RadCartesianChart.HorizontalAxis>

            <telerik:RadCartesianChart.VerticalAxis>
                <telerik:LinearAxis MajorStep="1"/>
            </telerik:RadCartesianChart.VerticalAxis>

            <telerik:RadCartesianChart.Behaviors>
                <telerik:ChartPanAndZoomBehavior x:Name="_panZoomBehavior" ZoomMode="Horizontal" DragToZoomThreshold="10" />
            </telerik:RadCartesianChart.Behaviors>
        </telerik:RadCartesianChart>

Real max zoom depends from data, Axis.Maximum/coef (>1).

Its wide range for axis X, so i update major step on zoom changing. 

        private void UpdateAxisMajorStep()
        {
            var xAxis = (LinearAxis) _chart.HorizontalAxis;

            double modelWidth = xAxis.Maximum - xAxis.Minimum;
            double viewWidth = xAxis.ActualWidth > 1
                ? xAxis.ActualVisibleRange.Maximum - xAxis.ActualVisibleRange.Minimum
                : modelWidth / _chart.Zoom.Width;
            xAxis.MajorStep = viewWidth / 10;
        }

Behaviour looks good, but when i'm trying zoom in with big factor perfomance slow down.

Chart shows 10 ticks and labels at horizontal axis, but looks like

    calculated labels count = Chart.ActualRange/MajorStep. 

For example Maximum = 500000, Visible range 0 - 5000 and MajorStep = 500, count of calculated labels =  1000. Perfomance becomes unusable.

Hi,

I'm using the last version of telerik and I was trying to integrate the RadPdfViewerToolBar into RadPdfViewer

This is my code

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="Auto"/>
        <RowDefinition/>
    </Grid.RowDefinitions>
    <telerik:RadPdfViewerToolBar RadPdfViewer="{Binding ElementName=pdfViewer, Mode=OneTime}" />
     
    <telerik:RadPdfViewer Grid.Row="2" x:Name="pdfViewer" DataContext="{Binding CommandDescriptors, ElementName=pdfViewer}"                              
                            RenderOptions.BitmapScalingMode="HighQuality"     />
    <telerik:RadPdfViewerToolBar/>
</Grid>

 

I populate the pdfViewer on datacontext change

private void RootElement_DataContextChanged(object sender, DependencyPropertyChangedEventArgs e)
        {
            if (e.NewValue != e.OldValue)
            {
                pdfViewer.DocumentSource = new PdfDocumentSource(new Uri(e.NewValue.ToString()));               
            }
        }

 

As shown on the attachment, the toolbar it seems not related to the pdfviewer.

Another question. Is it possible to specify a page number when I open the pdf? Something like GotoPage xy

 

Thank you

Its task is to execute RichTextBox commands.

So I created a binding for commands property:

<local:EditorToolBar
            x:Name="DescEditorToolbar"
            Grid.Column="0"
            DataContext="{Binding ElementName=DescEditor, Path=Commands}" />
 
<telerik:RadRichTextBox
            x:Name="DescEditor"
            Grid.Row="2"
            Margin="1,2,0,0"
            telerik:XamlDataProvider.Source="{Binding Description, Mode=TwoWay}"
            BorderThickness="0"
            DocumentInheritsDefaultStyleSettings="True"
            FontFamily="Verdana"
            FontSize="16"
            IsImageMiniToolBarEnabled="False"
            IsSelectionMiniToolBarEnabled="False"
            IsSpellCheckingEnabled="False" LayoutMode="Paged"/>    

 

At application start, property Description in ViewModel is filled with empty RadDocument xaml string and then user can edit it. It works fine, but for unknown reasons sometimes after application start, toolbar looks like it isn't binded to RichTextBox commands. Pressing Toolbar buttons doesn't change anything in edited Document. It looks like Toolbar and RichTextBox are not connected in any way.

 

Commands in RadRichTextBox are fine, because ctrl+z is working. Should I perform some refresh actions on Toolbar or something?

 

Thanks for any help,

Jakub.

Hi,

I'm having a lot of difficulties in understanding how to create the layout that I am looking for with RadDocking.  I have read the documentation and have looked at the examples however I am still having difficulties.

https://docs.telerik.com/devtools/wpf/controls/raddocking/getting-started/getting-started2#adding-radpane

Is it possible for someone to help me understand how to create the layout attached in my wireframe?

I am having a hard time getting tabs to be on the left, how to size things with RadSplitContainer and understanding the need of DocumentHost.

Thank you.

David

Hi,

We are using the RadMap control (v. 4.0.30319) in a MVVM WPF project .

In some cases we encounter an exception on the AsyncShapeFileReader while calling ReadAsync()

Exception Message: collection was modified; enumeration operation may not execute

Telerik.windows.controls.Map.MapShapeDataVirtualizationSource.QueryItems ( line 440)

I thought it was a cross-threading problem and inserted some changes in my code :

- calling this.Dispatcher.Invoke((Action)(() => AsyncShapeFileReaderObj. ReadAsync() ));       

- using async/ await

but both changes did not solved the problem and the exception still rize.

what could be the problem? Do you have another idea how can i solved it? 

The Main thread is calling the ReadAsync() and the other threads that i could see are background workers of Telerik's Map ...

Thanks,

Tali

Hello

I have complex class like this:

class person
    {
        string name;
        car Car;
    }
    
    class car
    {
        string model;
        string number;
    }

////////////////////////

 ObservableCollection<person> persons  = getAllPerson() ;

mainDG.ItemSource = persons;

////////////////////////

How can I bind it to my RadgridView?

<telerik:RadGridView x:Name="mainDG" Margin="259,0,5,5" AutoGenerateColumns="False" >
                        <telerik:RadGridView.Columns>

                                  <telerik:GridViewDataColumn Header="Car number" DataMemberBinding="{Binding Car.number}"/>//How can I bind it?

                       </telerik:RadGridView.Columns>

</telerik:RadGridView>
