TextControlBox-UWP
๐ค What is TextControlBox?
A UWP based textbox with syntaxhighlighting and support for very large amount of text which is still in development.
Reason why I built it
UWP has a default Textbox and a RichTextBox. Both of them are very slow in rendering multiple thousand lines. The selection works also very slow. So I decided to create my own version of a Textbox.

- Viewing files with a million lines or more without performance issues
- Syntaxhighlighting
- Outstanding performance because it only renders the lines that are needed to display
- Linenumbering
- Linehighlighter
- Json to create custom syntaxhighlighting
- Highly customizable
โ Problems:
- Current text limit is 100 million characters
- Currently there is no textwrapping
- First version for WinUI with many problems and bugs, but working Github

Create custom syntaxhighlighting languages with json:
{
"Highlights": [
{
"CodeStyle": { //optional delete when not used
"Bold": true,
"Underlined": true,
"Italic": true
},
"Pattern": "REGEX PATTERN",
"ColorDark": "#ffffff", //color in dark theme
"ColorLight": "#000000" //color in light theme
},
],
"Name": "NAME",
"Filter": "EXTENSION1|EXTENSION2", //.cpp|.c
"Description": "DESCRIPTION",
"Author": "AUTHOR"
}
To bind it to the textbox you can use one of these ways:
TextControlBox textbox = new TextControlBox();
//Use a builtin language -> see list a bit higher
//Language identifiers are case intensitive
textbox.CodeLanguage = TextControlBox.GetCodeLanguageFromId("CSharp");
//Use a custom language:
var result = TextControlBox.GetCodeLanguageFromJson("JSON DATA");
if(result.Succeed)
textbox.CodeLanguage = result.CodeLanguage;
Create custom designs in C#:
textbox.Design = new TextControlBoxDesign(
new SolidColorBrush(Color.FromArgb(255, 30, 30, 30)), //Background brush
Color.FromArgb(255, 255, 255, 255), //Text color
Color.FromArgb(100, 0, 100, 255), //Selection color
Color.FromArgb(255, 255, 255, 255), //Cursor color
Color.FromArgb(50, 100, 100, 100), //Linehighlighter color
Color.FromArgb(255, 100, 100, 100), //Linenumber color
Color.FromArgb(0, 0, 0, 0), //Linenumber background
Color.FromArgb(100,255,150,0) //Search highlight color
);
