Hello,

is there a way to style the RadToolBarOverflowPanel? Or add a template for its items?

I would like to display the button on the left side and show the tooltip next to it.

Any help would be appreciated.

Best regards :)

• 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 would like to use windows11 theme in my application, but when apply the theme every buttons in the toolbars are loaded of large padding and large margin.
Since I don't like this layout I can change it setting properties inside every button, but if I try to setting a style it is ignored.
I think that toolbar apply a style and overwrite my one.

Can I modify the layout without change every button in my application?

Thank you

Luigi

Hey :) 

is it possible, to let a RadToolBarTray or RadToolBar automatically use a second row if there is not enough space?
I know I can manuelly set Bands but then it will be always 2 rows. Even if there would be enough space.

Hi all!

This question is not accurate enough, the actual problem is described here: https://www.telerik.com/forums/radtoolbartray-itemtemplateselector-problems

***

I have not updated my Telerik components for years; last time I did, the radToolbars stopped working, and I have not had the time to look into it. So I reverted back to what worked, but now I feel it's time to get back on the track.

So here we go: programmatically generated toolbars on my main form do not display any buttons. I use toolbar and button view models that the UI components bind to. The entire set of toolbar viewmodels are built on the fly, and only empty toolbars show up. I have other UI components which have buttonless toolbar components placed onto them at design time, and those work when I add the buttons runtime, so the only difference I've found has to do with the non-working toolbars not existing at design time.

They work in RCWPF 2018.3.1016.45, so that's what I'm still using. This happened when I (briefly) upgraded to 2020.2.513.45, and the problem still exists in the current version.

The images show the two different versions. The dockable Conceptual model window contains an empty-at-design-time toolbar, which is populated when the UI is initialized. The main window contains a toolbar container which does not contain any toolbar components at design time.

Does anything come to mind immediately? If not, I will dig into my code.

And to be clear, the generated toolbarviewmodel has several buttonviewmodels on it. The same code builds the viewmodels in both cases.

Hi!

I have my own toolbar class, derived directly from RadToolbar:

<telerik:RadToolBar x:Class="MyNS.Components.MyToolbar"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
             xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation" 

             xmlns:viewmodel="clr-namespace:MyNS.ViewModel;assembly=MyNS.ViewModel" 
             d:DataContext="{d:DesignInstance Type=viewmodel:ToolbarViewModel}"

             mc:Ignorable="d" 
             d:DesignHeight="300" d:DesignWidth="300"
             VerticalAlignment="Top"

             DataContext="{Binding}"
             Visibility="{Binding ToolbarVisible, Converter={StaticResource BoolToVisibility}}"
             ItemTemplateSelector="{StaticResource ToolbarElementTemplateSelector}"
             ItemsSource="{Binding Elements}"

             Band="{Binding Band}"
             BandIndex="{Binding BandIndex}"                    
            >
</telerik:RadToolBar>

with

public partial class MyToolbar : RadToolBar
{
public MyToolbar()
{
InitializeComponent();
}
}

When I add this toolbar design time on my child forms it works nicely. The underlying ToolbarViewModel binds all the way, and I get the buttons I want when I run the app. 

But when dynamically instantiating new ToolbarViewModels to be shown on my MainWindow, I get empty buttonless RadToolbar instances, not MyToolbar instances. So I want to control what kind of toolbar gets instantiated. I have this in MainWindow.xaml:

<telerik:RadWindow x:Class="MyNS.MainWindow"
...

<telerik:RadToolBarTray
  Name="Toolbars"
  Grid.Row="1"
  ItemsSource="{Binding Path=Toolbars}"
  IsLocked="False"
  ItemTemplateSelector="{StaticResource ToolbarTemplateSelector}"
/>

</telerik:RadWindow>

The binding itself works. I get RadToolbars, but without any buttons on them. But I get the wrong kind of toolbar, and I thought the ToolbarTemplateSelector would do it, but it never gets called.

So I have:

public class ToolbarTemplateSelector : DataTemplateSelector
{
    public override DataTemplate SelectTemplate(object item, DependencyObject container)
{
// currently only one toolbar template

// THIS CODE IS NEVER RUN

return this.MyToolbarTemplate;
}

public DataTemplate MyToolbarTemplate { get; set; }
}

and DataTemplate.xaml

<ResourceDictionary 
...

<!-- compile error if removed, so the mainwindow reference correctly points to this -->
<vm:ToolbarTemplateSelector 
        x:Key="ToolbarTemplateSelector"
        MyToolbarTemplate="{StaticResource dtMyToolbar}"
    />

</ResourceDictionary>

and in PaneTemplate.xaml I have:

<ResourceDictionary 
...

<!-- app crashes on start if this is removed -->
    <DataTemplate x:Key="dtMyToolbar" DataType="{x:Type vm:ToolbarViewModel}">
        <components:MyToolbar />
    </DataTemplate>

</ResourceDictionary>

In my mind, whenever a new ToolbarViewModel is added to the Toolbars collection, the ToolbarTemplateSelector should instantiate a MyToolbar instance for it, and not a RadToolbar instance. 

I have no idea what's missing. 

Oh, I also tested with:

<telerik:RadWindow x:Class="MyNS.MainWindow"
...

<telerik:RadToolBarTray
  Name="Toolbars"
  Grid.Row="1"
  ItemsSource="{Binding Path=Toolbars}"
  IsLocked="False"
>
<DataTemplate>
<ksc:MyToolbar/>
</DataTemplate>
</telerik:RadToolBarTray>
...
</telerik:RadWindow>

But then the app crashes with the error message "Items collection must be empty before using ItemsSource." before the main window shows up. I don't see why that would happen, as the toolbartray is definitely empty at first.

Appreciate any help,

Kim

Having an issue where I have put a textbox in a toolbar.

The textbox Text is  bound to a property of a Viewmodel but the setter does not get exercised.

it seems as though focus is never lost from the textbox even if the next item does receive focus.

I would have sworn I have used this setup before without issue.

I pulled the code into a simpler project just to verify I was not crazy and it acted the same.

if I pull the textbox out of the toolbar it works fine.

It must be something stupid I am doing. but  i cant see it. What am I doing wrong.

Any help would be appreciated

            <telerik:RadToolBarTray Width="400" >
                <telerik:RadToolBar >
                    <TextBox Text="{Binding Main.Cali ,Mode=TwoWay}" Width="100" />
                </telerik:RadToolBar>
            </telerik:RadToolBarTray>

Thanks

Dave.
