Visual Studio WPF Xaml Page PathGeometry String Max Length

Question

Visual Studio WPF Xaml Page PathGeometry String Max Length

vincent219 256

Hello.

I am developing wpf in .NET Framework 4.8 using visual studio 2022 pro version.

I converted a 32 x 31 size png image into a svg file using an online converter site.

Then I converted svg to xaml code with this github program.

Then, the path information of the attached file was output.

Then, after copying and pasting the xaml of this file, visual studio does not recognize xaml as xaml from the next line, so IntelliSense does not work.

It behaves like a regular txt file.

Of course, it is well represented at runtime as a path image of the intent I want.

Does visual studio not recognize a string path longer than 36000 in length?

225254-path.txt 225216-%E1%84%86%E1%85%A2%E1%84%85%E1%85%A7%E1%86%A8%E1%84%8B%E1%85%A1%E1%84%8B%E1%85%B5%E1%84%8F%E1%85%A9%E1%86%AB.png

Hi,@vincent219 .

Then, after copying and pasting the xaml of this file, visual studio does not recognize xaml as xaml from the next line, so IntelliSense does not work.

Which line are you referring to after unrecognized? Is it possible to show expected and actual problems with screenshots?

If you look at the xaml code screenshot I attached, I marked it in red.

There are 5 GeometryDrawing elements, and the first and second GeometryDrawing elements are recognized as xaml and the text color is blue in visual studio.

But then the third GeometryDrawing is the problem. The third GeometryDrawing is problematic path data over 36000 characters.

From the bottom line of this code including this line, you can see that all the code is like a text file.

If you look at the Grid.Column color of the TextBlock element, it should be originally blue. But in the screenshot, it is recognized as plain text and is white.

This is the problem.

There are some screenshots, but all the code below it is white like that.

You can reproduce the same symptoms as me if you create an Image and insert the xaml code in the path.txt file attached to the long xaml file as a Source.

If you understand the intent of my question, please provide a solution.

The reason why this is a problem is that since it cannot be recognized as a xaml code file, the subsequent code cannot be auto-completed through intelisense, and the indentation does not work as desired when a newline is entered with Enter.

Thanks for the reply.

Hi,@vincent219 . It might be an IntelliSense problem. You could split the Geometry of the longest data into two lines.
Pressing enter before this position splits the data into two lines and IntelliSense works fine.

Pressing enter on this position splits the data into two lines, IntelliSense does not work.
