QUESTION
ANSWER
Answered 2022-Apr-15 at 16:48While the approach in my comment will work, I thought of an even easier way. Just copy the style for TextArea from the source and modify it to include some margin on the right of the ItemsControl that contains all the editor's margins. The style is here:
And here's a complete example:
QUESTION
I am trying to dynamically create DataGrids in WPF, one below the other in a Grid. the problem is that I don't even know where to start, I saw that it could be done through code but I would like to use XAML correctly.
ANSWER
Answered 2020-Aug-27 at 16:54I do not know the exact layout where you want to put all the DataGrids, so I just assume you want to place them in row 2 of your Grid. As you want to stack them, you can use an ItemsControl in a ScrollViewer. The latter is just there, so you can scroll through the DataGrids in case the page is too small to display them all. So this is the basic layout for the solutions below.

I'm using AvalonEdit and working on adding syntax highlighting for a file (with syntax a bit like razor). It's my first time using XSHD files so please forgive me if this is actually easy.
The issue I'm experiencing can be seen with the following example code:

QUESTION
In my AvalonEdit-based document editor, I am trying to add marker lines to the text view to indicate folds in the document, in a similar way to how Visual Studio joins the start and end of code block braces with dotted lines.
I have something that produces the correct result if the document is scrolled to the very top, but it doesn't update correctly if the document is scrolled down. Specifically, the lines are drawn as if the text view wasn't scrolled at all, and was still at the top of the document. I suspect the problem has something to do with the TextViewPosition and GetVisualPosition lines, but I don't understand how to correctly get the adjusted visual position with scrolling.
(To be clear, I have checked, and the Draw method is being called at the appropriate times to update the background, it's just that scrolling isn't accounted for when it does)
What I have so far, is the following, on a class which implements IBackgroundRenderer:
ANSWER
Answered 2020-Jul-22 at 17:35GetVisualPosition is documented as:
Returns: The position in WPF device-independent pixels relative to the top left corner of the document.
To use it for painting, you'll want to subtract the scroll position from it:

I'm using AvalonEdit to create an ANSI terminal that properly color codes and implements some styles like underline and reverse (it works wonderfully for that, this isn't a full VT100 kind of thing).
In AvalonEdit a DocumentColorizingTransformer to transform ANSI color codes into colored text or styled text. Last night I was working on implementing the ANSI Blink. I got the blink working with this section of code:
ANSWER
Answered 2020-May-14 at 18:17WPF will render at 60 frames per second if there's any animations running. The rendering is relatively fast if there are no actual changes, but it still causes noticable CPU usage when the application is supposed to be idle. AvalonEdit's caret is toggled on-off (with a timer) instead of using an animation to avoid rendering more frames than necessary.
In the DocumentColorizingTransformer, you can use this.CurrentContext.VisualLine to access the VisualLine being processed.
The VisualLine has an IsDisposed property that will change to true once the AvalonEdit has discarded the line (and would call your colorizer again if the line becomes visible again).
There is no event telling you when the line has been disposed. But if you keep track of all animations+their containing VisualLines in a list, you can use the TextView.VisualLinesChanged event to scan for VisualLines that were disposed and stop the corresponding animations.

Hello,
I try to use ReactiveUI.Validation package
To Validate Wpf Simple App
And Validation works i can see it in ViewModel valid state
But I can not see any notification to view element
I mean no red border or any type of error appear, even when using MaterialDesignPackage, Custome Templates nothing works!
ViewModel.cs
...ANSWER
Answered 2020-Apr-03 at 20:21Binding the validation to a control template is currently not supported but you can show a validation error message in the view if you bind it to a seperate textblock (Documentation).
If you just want to use the MaterialDesign HelperText to show an error message, you don't need to use ReactiveUI.Validation but could do something like this:
QUESTION
Column/rectangular selection is dragging a rectangular selection frame over the text (for example with Visual Studio with Alt+Drag) and only select that text without selecting entire lines.
Is there any control for WinForms / WPF with that capabilities?
The Winforms Textbox, RichTextBox and WPF Textbox, RichTextBox don't provide this functionality.
The code editor controls like AvalonEdit or Scintilla.NET also don't know about this (I maybe wrong, but their documentations do not mention such things).
...ANSWER
Answered 2020-Jan-23 at 15:43The AvalonEdit control indeed has a column / rectangular selection mode. They didn't seem to care about mentioning that, but using the appropriate control ICSharpCode.AvalonEdit.TextEditor either inside WPF or an ElementHost inside a WinForms application does the trick.
