RadRibbonView : Space between title and controls

[Valentin]

Hi everybody,

 

I'm using a RadRibbonView. When the window is full screen, i've no problem (file_1).

When the window is more small, the width of RadRibbonView is decreasing, and the RadRibbonTab witdh, too (file_2). The components are grouped in the same menu ("Navigation").

But, the space between the title ("Navigation") and his components is created (file_3), and I can't delete it.

 

My code :

<telerik:RadRibbonView Grid.Row="0" Grid.Column="1" HelpButtonVisibility="Hidden" ApplicationButtonVisibility="Hidden" 
                                        TitleBarVisibility="Collapsed" HorizontalAlignment="Left" TitleBarBackground="{x:Null}" 
                                        IsMinimizable="False" Height="82">

I've tried to change de Height ("Auto" for example"), but it dosen't work.

 

<telerik:RadRibbonTab Header="Graphiques" Height="Auto" VerticalAlignment="Top" >

(The all of RadRibbonTab have the similar code)

<telerik:RadRibbonGroup Header="Navigation" Height="Auto" VerticalAlignment="Top">

(The all of RadRibbonGroupe have the similar code)

Hello Valentin,

The RadRibbonView has a lot of components inside of it, which want to keep their heights. When you simply set Height on the whole RadRibbonView, it only visually clips its contents and so the popup is placed at the place that is was expected originally to appear, resulting in the spacing between it and the ribbon. The way to change the Height of the RadRibbonView is by accessing its property ContentHeight, which sets the height of the items presenter. The tabs at the top are not included in that measure so in your case, if you want to achieve 82px height of the whole ribbon - you should set the ContentHeight to 59, because the TabControl header is 23px in the VisualStudio Theme.

This will however clip the image of the grouped components, because it has a fixed Height. You can change those values in the RadRibbonGroupStyle > RadRibbonDropDownButton > Image By extracting and editing a copy of the control template of the RadRibbonGroupStyle. You can consult the styling guidelines of the RadRibbonView for any cases specific to it.

Hi Martin.

Is that i searched ! It's working fine. Thank You.

 

I've 1 others questions :

I tried to put "Auto" value in ContentHeight, but it doesn't work. I tried this because the icon of RadRibbonGroup is cuted. 

Solutions :

- Hide this icon.

- Decreasing the size of this icon.

But how i can do one of this solutions ?

Hi,

To change the size or the visibility of the icon you can modify  the RadRibbonGroup template. You can do that  by extracting the RadRibbonGroup Control Template and  target all the RadRibbonGroups with an implicit style <Style TargetType="{x:Type telerik:RadRibbonGroup}"> (by removing the x:Key of the style you target all the elements from a certain type). In the ControlTemplate you will find a <Border x:Name="Image"...> with width and height set to 32px. You can change either the Border's  size or the visibility of the images.

Hi,

 

I have an other question about spaces :

- I want to do that the with of the RibbonView (OR) RibbonTab content takes automaticaly the all of width (like picture '2' : For this screen, it's my bolds labels which do this).

I searched a WidthContent property but I don't find it.

Now, is like picture '1'.

 

Thank you very much.

Hi Valentin,

To stretch the ribbon you could try setting its HorizontalAlignment="Stretch"  and the same for the right column if you are using a Grid to place them. You could set the Grid.Column's Width="Auto" (for the one where the RibbonView is placed). This way the RibbonView should stretch regardless of its contents.

However, keep in mind even if you stretch the ribbonview, the content of its tabs won't be stretched. In order to stretch them you can implement custom RibbonGroupsPanel.

Hello Martin,

 

My HorizontalAlignment is set to "Left", not "Stretch". I used grid, and my secondary Grid.Column's width it was set to "Auto". => It's working !

 

Thank you very much.

For the RadRibbonGroup's Icon problem, I do not arrive to hide it / OR / decrease his size..

Hi Valentin,

I am pleased that it is going well so far. 

As for the icons - I am attaching a ResourceDictionary with the complete ControlTemplate of the RadRibbonGroup that I have extracted through the Visual Studio designer and I have marked with a comment the part of the code that you need to find in your project and change the values there (it is a Border x:Name="Image"). Right now I have set its size to 10 by 10 with margin 3, so that means the inner Grid>Image need to be with dimensions 16. You can change these values or even hide the whole icon.
