How do you create a control that horizontally scrolls the text to show text that are to long?
So instead of character overflow i would like it to scroll from side to side.
I've seen controls that does a continues scroll but that's not what i look for.
Not clear wih your Question. Something like this.
<TextBox Width="500" Height="50" ScrollViewer.HorizontalScrollBarVisibility="Auto"/>
Dont know where I have to put animation here :)

I'm trying to auto scale the font and wrap text in a TextBlock in WPF and I can't figure it out.
I've Googled it and looked at stackoverflow loads of times and the main suggestion is to place a TextBlock inside a ViewBox. I've tried that, and all it does is scale the whole text down to one line instead of wrapping it.
If I just use a TextBlock without a ViewBox it wraps, but doesn't scale to fit. It's driving me mad, as I am literally trying to move from WinForms to WPF to make better looking UIs.
I've tried StackPanel and DockPanel and they still don't have the desired effect.
All I want is a TextBlock to take a string of text of unknown size and display it scaled and wrapped. I don't understand why it's so difficult
It is helpful to include code of what you have tried.
When I do this:
<Grid>
<TextBox VerticalAlignment="Center" TextWrapping="Wrap" Width="100"/>
</Grid>
I get this:
Is that what you are looking for?

In my xaml, I have some object made by me. I put them in row and, if the window is too little for all, I go in a new line.
The problem is when the window is so little that, also in a new line, the elements can't be all shown. The solution is simple: scroll bar!! But, if I set the Vertical/HorizontalScrollBarVisibility to auto, it doesn't go to a newline anymore.
This is my xaml:
<ScrollViewer CanContentScroll="True" VerticalScrollBarVisibility="Disabled" HorizontalScrollBarVisibility="Disabled" >
<ItemsControl Name="ItemGroups" ItemsSource="{Binding NotifyItemUI}" />
</ScrollViewer>
and this is a screenshot what I need as my goal:
For example, if I resize my area vertically, and I have 3 rows of objects, in this way I can't see the third row if the window becames too little. In this case, I'd like to see a vertical scrollbar to scroll it.
Same thing horizontally: if I have too many elements for one single row, I have to scroll it horizontally.
What you describe looks like a WrapPanel, but the way you write about it suggests it is a custom control, so we cannot see what your ItemsControl is doing for layout.
However, ScrollViewer can have tricky interaction with a Panel. If the Panel measures to infinity, it will always consider itself big enough, and never tell the ScrollViewer it is out of room. The result is that the ScrollViewerdoes no know the scrollbar is needed. If this is your problem, then setting the Width and Height properties, or maxima as #Sheridan said, ought to fix it.
I have a semi transparent grid on a window . I have placed a button in grid cell.
now I want to be able to set the button text transparent, but not background ie., I want to set some background color to button and I want to be able to see through the button text.
Please somebody could help me on this.
I am a bit confused what you mean to acquire but if you want to be able to read across text you can cut it out. To do this you create for instance a square, put a text into it and cut out this text (for instance in gimp) so you will obtain a png file which looks like first picture (at first glance foreground reminds white but it is transparent). Then you add picture to project and
<Button Opacity="1" Background="Goldenrod" Width="100" Height="100">
<Button.OpacityMask>
<ImageBrush ImageSource="fileWithText.png"/>
</Button.OpacityMask>
</Button>
The second picture depicts result. Background of grid is set to blue what we can presume thanks to text which is cut out. It is not efficient way out since not everything can be done only in WPF but I hope you will take advantage of it.
I'm running into a dilemma. When I make the ScrollViewer the main content object of my window, scrolling behaves exactly like I want it to. You resize to make it smaller than the content and the window and scroll bars appear. The problem comes in when I want the to menu to be static and the rest of content to be scrollable. I want the scroll bars to behave the same way as a browser window does, meaning when you resize it, the scroll bars appear based on the size of the content. When you expand the window, the content takes up the entire real estate of the window. Is that possible in WPF?
Help would be GREATLY appreciated.
Make a DockPanel the main content object of your window. Insert your top menu as the first child (with DockPanel.Dock="Top") and the ScrollViewer (containing the rest of the window's content) as the second child. In a DockPanel, the last child takes up all the remaining space, which should be what you want.
<Window ...>
<DockPanel>
<MyMenu DockPanel.Dock="Top" ... />
<ScrollViewer>
....
</ScrollViewer>
</DockPanel>
</Window>
I have a long text and show first sentence in a TextBlock.
I wish by clicking the TextBlock or a button to show a panel below the TextBlock with full text. I wish this panel be absolutely positioned and be displayed above any other elements, you can do a similar thing in HTML showing and hiding absolutely positioned 'div' element.
How to do this in WPF?
Thank you for any suggestions.
AdornerLayer can work, but may be a little complex. Other options include using PopUps or ToolTips -- you should look into those first as your easiest options.
If these all don't work, it'll really depends on what kind of panel you're using. For example, if you're using a Canvas, all you have to do is make sure to set the correct ZIndex on the element.
In order to make this more robust, I'd suggest the following:
<!-- Set Panel.ZIndex="99" when showing hidden area to ensure top placement -->
<Grid>
<TextBlock>This is my primary bit of text ...</TextBlock>
<!-- Canvas stays hidden until we want to show the rest of the text -->
<Canvas Visibility="Hidden">
<TextBlock Canvas.Bottom="-10">Content goes here</TextBlock>
</Canvas>
</Grid>
Put the long text in an AdornerLayer is the best option. Check out some links
