  • I just downloaded the most recent trial
  • I installed the nuget package
  • I pasted the xaml from "PdfViewer FirstLook Demo" in the SDK Sample Repo
  • Everything is working fine in term of functionality at design and runtime
  • *Except the theming is AWFUL looking (though in your Telerik Demo App Win11 looks really great and that's what I need)

 

Also, can't install the SDK Sample Browser (it says I need sharepoint, which I installed and it still says I don't can't install it.. anyways it looks like old stuff why not use a recent installer?).

Honestly, I tried a month ago Devexpress, and I found their product WAY MORE easier to use; the theming mechanism is super intuitive (ThemeManager.ThemeName="Win11Light" that's it, just out of the box). Unless I'm missing something with Telerik?

I hope you can help me so I can eventually enjoy Telerik which looks nice in the Demo (But I wasted A LOT of time trying to resolve these 2 issues (theme and installing the SDK Browser)

Thank you.

Hi,

I have the RadPanelBar in figure:

I would like to draw a border around all the items inside a RadPanelBarItem. If I set border in RadPanelBarItem I get the effect as in figure: only the header is bordered while the inside items are not.
My purpose id to hilight the item not the header, is there any way to achieve this?

Thank you

Luigi

Hello,

During project implementation a wrong link connection was found.

Precondition:

When we have two models of ContainerNodeViewModelBase OuterModel and InnerModel.

InnerModel has set to true "RadDiagramShapeBase.UseGlidingConnector".

Steps to reproduce:

1. Put InnerModel inside OuterModel.

2. Connect the top middle connector to middle connector of InnerModel

3. When you move InnerModel in upper part of OuterModel the link is connected to bottom of InnerModel instead of to top.

To make reproduce easier i attach video, and i modified your sample application (PasteOnMousePosition) to reproduce this issue.

I attached both things.

Video desc:
1st use case with no gliding connector -- looks ok

2nd use-case movement outside of container and the link looks ok, but the link connection inside looks bad.

Currently this link is just a line, but when it would be an arrow then its looks even worse.

Hi


I use the RadDateTimePicker and have a button ("Next"):

When now the user changes the date/time value to an invalid date/time an error is shown:

When the user clicks on the "Next" button the DateTimeText disapears and is empty and an error is schown:

My Question:
Is it possible to set the DateTimeText to the previous wrong formatted date/time (120000000000.07.23 08:49) like this ? 

I have tried to overload the method  OnParseDateTime and set the CurrentDateTimeText but it's not working.

Hi, i'm having a rough fight with WPF and its Binding system. I just wanna bind a property of an instance called HPP, this property is pressure and this object exist in MainViewModel, so in MainWindow.xaml a have this:


<componentes:SetComponent x:Name="HPP_Trip_Route" Grid.Row="1" Grid.Column="1" VerticalAlignment="Top" Title="TRIP" VariableValue="{Binding HPPRoute.Pressure}" Unity="PSI" Loaded="SetComponent_Loaded" FSizeTitle="24" FSizeVariable="36" FSizeUnity="14"/>
In SetComponent:
<TextBlock x:Name="ValueSetComponent" Grid.Row="1" Text="{Binding VariableValue, RelativeSource={RelativeSource AncestorType=UserControl}}" FontSize="{Binding FSizeVariable}" HorizontalAlignment="Right" VerticalAlignment="Bottom" Foreground="#FFFFFF" Margin="0, 5, 0, 5 "/>
Dar clic y arrastrar para mover
In MainWindow.xaml.cs:

public partial class MainWindow : Window, INotifyPropertyChanged
    {
        private readonly Variables GV = Variables.GetInstancia();
        private MainViewModel _mainViewModel;
        public MainViewModel MainViewModel
        {
            get { return _mainViewModel; }
            set
            {
                _mainViewModel = value;
                OnPropertyChanged();
            }
        }

        public MainWindow()
        {
            InitializeComponent();
            GV.MainViewModel.StartAssign(GV);
            MainViewModel = GV.MainViewModel;
            GV.MainViewModel.MainWindow = this;
            DataContext = MainViewModel;
     
        }
        public event PropertyChangedEventHandler PropertyChanged;

        protected virtual void OnPropertyChanged([CallerMemberName] string propertyName = null)
        {
            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
        }

I tried with RelativeSource without success. If i create a variable in MainViewModel it works. Any help?

I have a Radgridview with merged cells. When I select a merged cell, the selected row in the ViewModel does not change. I need to get all rows whose cells are included in the selected merged cell. Can it be done?

We use RadCombobox (WPF) for loading more than 20000 items.

We enabled the following properties and removed the Virtualization properties. We are facing performance problems on searching the items from RadCombobox element. How can we improve performance for the RadCombobox load and search, if virtualization properties cannot be used.

<telerik:RadComboBox
x:Name="itemBox"
HorizontalAlignment="Stretch"
CanAutocompleteSelectItems="True"
DisplayMemberPath="Name"
EmptyText="Select the item"
IsEditable="True"
IsFilteringEnabled="True"
IsTextSearchEnabled="True"
ItemsSource="{Binding ItemCollection, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
OpenDropDownOnFocus="True"
ScrollViewer.VerticalScrollBarVisibility="Auto"
SelectedItem="{Binding SelectedItem, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
TextSearch.Text="Name"
TextSearchMode="Contains" />

Hello! I need to merge cells in all columns. In my example, the screenshot shows that Sam in the "Name" column is merged for two different people who are part of different companies. Is it possible to make the cells merge based on the columns on the left? That is, if Sam is part of different companies, then he does not need to be merged.
What I want is in the attachment
