Hi Team,

     I am very new to WPF world and we are designing an application which will be having multiple menus and sub menus. As the application is bigger and having lot more functionality we are using Modular approach defined by PRISM along with complete use of MVVM(zero code behind). We are using Telerik controls for rich UI and for design of the Menu we are using Navigation View(Hamburger Menu). While designing such architecture we are facing many issues as follows:

1. How to bind command to the Navigation View Item events for MVVM prism architecture? I have tried many ways to achieve this but no success(Approaches are mentioned below the questions).

2. How to navigate and load different pages or user control on click of the Navigation View Items as our pages or user controls are present in separate application?(PRISM Modular approach)

3. Want to load this contents in ContentControl Prism Region Manager at runtime.

I have gone through the documentation of Rad Navigation View but not found any ways to achieve the above issues.

Below is the approach we tried to bind command.

1. Approach One :  Tried setting in Style with property setter at both ItemStyle and ItemBaseStyle but both are not working.

2. Approach Two : Tried with Telerik event Command Behavior Event Bindings. 

3. Tried in Telerik radNavigationView.Item it is also not working

We are able to show the static value like title with the below code : 

But instead of the RadNavigation View Content we wanted to use Content Control to load dynamic controls using MVVM and Prism like this.

Below is my ViewModel Code.

Kindly Help us to achieve this.

Hello 

I have a TimeBar which Connet is a Cartesian chart. The Period Start and End are the Min and Max dates in the source of the Cartesian chart items. For some reason, the start and the end of the cartesian chart does not align with the boundaries of the TimeBar. As if the chart has has some margin/padding that prohibits it to align with the TiemBar boundaries. (see atteched graphs).

Here is the xaml of the Timebar + cartesian chart:

<telerik:RadTimeBar Height="150" VerticalAlignment="Top"
                            PeriodStart="{Binding PeriodStart, Mode=TwoWay}"
                            PeriodEnd="{Binding PeriodEnd, Mode=TwoWay}"
                            VisiblePeriodStart="{Binding VisiblePeriodStart, Mode=TwoWay}"
                            VisiblePeriodEnd="{Binding VisiblePeriodEnd, Mode=TwoWay}"
                            SelectionStart="{Binding SelectionPeriodStart, Mode=TwoWay}"
                            SelectionEnd="{Binding SelectionPeriodEnd, Mode=TwoWay}">
            

        <telerik:RadTimeBar.Intervals>
            <telerik:YearInterval />
                <telerik:QuarterInterval/>
                <telerik:MonthInterval />
            <telerik:WeekInterval />

How do I get the text to wrap rather than scroll horizontally.

Thanks,

Hi,

Is it possible to paste some copied data into a RichTextBox as an image like you can in Outlook?

We have  a table in excel that we would like to paste in so it is an image in the RichTextBox rather than an editable table.

I have had a look around the forum and the docs but I can't see anything.

Thanks,

Steve

Hello.

I was asked to make the scheduler show hours for the day in two columns if no grouping is selected.

i;e.: if my day has hours from 8am to 6pm, show two columns for the day: one with hours 8am to 12:59am and one with hours from 1pm to 6 pm. much as you can find in any mid sized scheduling book.

Is there a way to do that? or any hints to how to... 

Thanks in advance...

Good day,

Is there a way I can access the filter value used in the GridView and Show it to other part of my page? Just like the SelectionBox of RadMultiColumnComboBox with the column and operation used?

Thank you.

We are using the Teleik rad gridview in our WPF application but we are experienceing a memory leak. The problem with this leak is that i'm not able to reproduce it in a example application so i cannot send anything. Below is the information I get using dotMemory:

Type, Allocated bytes, Allocated objects, Collected bytes, Collected objects
Telerik.Windows.Data.WeakEvent+WeakListener<System.ComponentModel.PropertyChangedEventArgs>, 81600, 3400, 79200, 3300
2 (2x24bytes)

Telerik.Windows.Data.WeakEvent+WeakListener<System.Collections.Specialized.NotifyCollectionChangedEventArgs>, 72000, 3000, 69600, 2900
2 (2x24bytes)

Because I am not able to reproduce the issue I wonder if you guys can give me some tips and pointers about how to diagnose this problem. Below you'll find information about the OS, Visual studio version and the used telerik version. The backtrace does not contain any of our own code.

Windows 10

Visual Studio 2015

.net framework 4.6.1 C#

Telerik version:2019.1.220.45
