Can i create a RadWindow that can be resizable but without Maximize and Minimize button?

[Michael Chong]

As what the title says.

Hope for any help and information.

Thank you.

Hello Michael,

Yes, you can do this. What you need to do is to change the ControlTemplate of the RadWindow control and to remove the buttons from the original one.

If you have further questions, don't hesitate to ask.

Hi Rodrigo,

 Could you please send us a sample project that reproduces the issue - this will help us find out what causes the problem?

Hi,

let me try ti explane.

i created a user control, with a RADWINDOW. On the style i remove the buttons Minimize and Maximize.

    >

    <UserControl.Resources>
        <SolidColorBrush x:Key="BorderShadowColor1" Color="#0C000000"/>

            <GradientStop Color="#FFDEDEDE" Offset="1"/>
            <GradientStop Color="#FFFFFFFF" Offset="0.35294289873343759"/>
        </LinearGradientBrush>
        .
        .
        .
        .
            <Setter Property="HorizontalAlignment" Value="Left"/>
            <Setter Property="VerticalAlignment" Value="Top"/>
            <Setter Property="WindowState" Value="Normal"/>
            <Setter Property="WindowStartupLocation" Value="Manual"/>
            <Setter Property="Header" Value="RadWindow"/>
            <Setter Property="Margin" Value="0"/>
            <Setter Property="TabNavigation" Value="Cycle"/>
        </Style>
    </UserControl.Resources>

    <Grid x:Name="LayoutRoot">
        <telerikNavigation:RadWindow x:Name="window" VerticalAlignment="Stretch" Content="RadWindow" d:LayoutOverrides="Height" HorizontalAlignment="Stretch" Style="{StaticResource RadWindowStyle}"/>
    </Grid>
</UserControl>

To open this custom window i´m using:

           JanelaCustomResizableView janelaAbrir = new JanelaCustomResizableView();
            janelaAbrir.window.ModalBackground = new System.Windows.Media.SolidColorBrush(System.Windows.Media.Color.FromArgb(150, 0, 0, 0));
            janelaAbrir.window.ResizeMode = ResizeMode.CanResize;
            janelaAbrir.window.WindowStartupLocation = WindowStartupLocation.CenterOwner;
            janelaAbrir.window.Header = "Abrir Projeto";
            janelaAbrir.window.Content = new AbrirProjetoDePortal(janelaAbrir.window);
            janelaAbrir.window.ShowDialog();

this works fine.

But when i need open a new window without closing the first one the second window does not open..

Hi Rodrigo Mamede,

I'm sorry for the late response.
Could you share we us your project so that we can get better understanding on your scenario? (in order to attach files you have to open a support ticket).
How do you open janelaAbrir.window for the second time?

Kind regards,

Expecting people to modify a control template for what should be basic, supplied properties is a brain - dead solution, sorry :(
The ResizeMode property should be changed to add the ability to hide the minimize, hide the maximize and retain resizing if desired.

Your minimize function is also worthless if the user has set a minimum size and ends up removing the content of the window, rather than rolling it up into the header as it does when minimum size is not selected.

[Miroslav Nedyalkov]

Hello Colin,

 We are currently working on the case with hiding the buttons independently of the WindowResizeMode property. This will be possible by handling and stopping the commands of the buttons. This feature will be included in the Q3 release.

Setting MinWidth and MinHeight will prevent the whole control to become smaller than these sizes - this is how the Silverlight/WPF layout works and we cannot change that. What you can do is to hook-up to the WindowStateChanged event and to reset the MinWdith/Height if minimized and to restore it if not.

Hope this helps!

Sincerely yours,

Hi,

I haven't tried Q3 yet. Has this feature been implemented?

I'm trying to create a RadWindow that can be resized, closed and maximized but not minimized. Is this possible to do without having to change the control template? Honestly having to change the control template to tweak some basic window functionallity seems to me like a hack.

Best regards,
Manuel Felício.

[Miroslav Nedyalkov]

Hello Mario,

 What you need to do to stop minimizing functionality is to handle and stop the WindowCommands.Minimize command. Here is an example that demonstrates how to hide the Minimize button:

var window = new RadWindow();
CommandManager.AddPreviewCanExecuteHandler(window, (s, e) =>
{
    if (e.Command == WindowCommands.Minimize)
    {
        e.Handled = true;
        e.CanExecute = false;
    }
});
window.Show();

All the best,
Miroslav Nedyalkov

[Denis Vuyka]

As for "CommandManager.AddPreviewCanExecuteHandler"...
This seems to be a workaround rather than a solution as for me, sorry. I would discourage people using such approach for production code even if someone proves this code does not provide memory leaks. 
Can we just have a dedicated API for that? Something like "ShowMinimizeButton" property, so that everyones configures the behavior, and your control has all the implementation the way you want it.
Thanks in advance,
Denis

[Miroslav Nedyalkov]

Hello Denis,

 Thank you for sharing your opinion. Actually this code shouldn't produce any memory leaks if the handler is a static method instead of anonymous method. The example is using an anonymous method just for shortcut.

The reason why we didn't add property for the minimize button is that we don't want to add such property for every single visual element of the RadWindow. The correct way to remove visual parts is to change the ControlTemplate of the control and as you correctly noticed handling the PreviewExecute is a shortcut for this, not for a missing feature.

Best wishes,

Is there no easier way to choose which button options you want to be exposed on a per-window basis? Having a completely different template style for each type of window makes little sense. 

Thanks!
Kevin

[Miroslav Nedyalkov]

Hi Kevin,

 You could use either the approach I suggested in this thread (by handling the button commands) or to directly remove the buttons in the style. Hope this helps.
