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

I populate the pdfViewer on datacontext change

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

Hi,

I have simple RadToolBar with RadRibbonButtons mostly:

Its task is to execute RichTextBox commands.

So I created a binding for commands property:

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.

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?

Hello Telerik,

On my project, I have a RadDiagram with some shapes, and inside, text is defined.

I need to export this RadDiagram to a PDF File > I create a Bitmap Image from the RadDiagram, and insert this image in the PDF file.

However, texts in the PDF should be selectables. So, before the export, I hide all of texts, and I write them directly inside the PDF after it generation.

From a Textblock, I save primordial informations, and hide the text :

ParsedTextBlock is a custom class to store some properties.

After, I have some methods to export Textblock :

Me._ptb is a list of ParsedTextBlock.

And :

With these methods, for a text not rotated, it's OK. But the problem is when the text is rotated.

You can see the Origin screen, this one is the RadDiagram before exportation, and the Result screen, this one is the result inside the PDF.

And depending to the rotation angle, the result for rotated text is so bad.

My excpectation is that the position from the TextBlock is bad (calculation is false ?)...

I hope you can help me to write at the good place a rotated TextBlock.

Thank you.

I'm getting a parameter count mismatch, I narrowed it down to an indexed property on the viewmodel that the data form is bound to, but not even using.

System.Reflection.RuntimeMethodInfo.InvokeArgumentsCheck(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture)
System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture)
System.Reflection.RuntimePropertyInfo.GetValue(Object obj, BindingFlags invokeAttr, Binder binder, Object[] index, CultureInfo culture)
System.Reflection.RuntimePropertyInfo.GetValue(Object obj, Object[] index)
Telerik.Windows.Controls.RadDataForm.OnCurrentItemPropertyChanged(Object sender, String propertyName)
Telerik.Windows.Controls.RadDataForm.OnCurrentItemPropertyChanged(Object sender, PropertyChangedEventArgs e)
System.ComponentModel.PropertyChangedEventHandler.Invoke(Object sender, PropertyChangedEventArgs e)

I saw in the forum other references to this error and some with very similar stack traces. Most said a fix would be in the next version. Is there something I am doing wrong, or is this just a bug in the data form? Is there a way I can override OnCurrentItemPropertyChanged and handle it myself (or skip it in this case, of not actually even using the parameter).

Hi Progress Telerik,

I would like to change the look of the Relation Arrow between tasks. Is there any way to style the relation arrow in GanttView? Please provide the solution to achieve the same.

Thanks and Regards,
