Can I set text properties for specific words in an EditControl

[Mike Anderson]

Does EditControl allow for setting text properties for specified sub-text (strings or words within the entire text). I'd like to programmatically set a color or font for specific key words within an EditControl.

Hi Mike, 

Thanks for contacting Syncfusion support. 

Query : Does EditControl allow for setting text properties for specified sub-text (strings or words within the entire text). I'd like to programmatically set a color or font for specific key words within an EditControl. 

We can give different colorings to text based on the Format(keywords, literals, comments…etc) through CustomLanguage. We have checked your query and prepared sample which tries to meet your requirement. In this sample we have changed the fore color of the Text based on the Format name in the Format collection. 

Code example : 

Format snippet: 

        private List<EditFormats> formats = new List<EditFormats>() 

        { 

            new EditFormats() { Foreground = Brushes.Blue, FormatName = "KeywordFormat" }, 

             new EditFormats() { Foreground = Brushes.Green, FormatName = "CommentFormat" },            

               new EditFormats() { Foreground = Brushes.Navy, FormatName = "OperatorFormat" },                           

        }; 

Lexes collection : 

 

private List<Lexem> lexems = new List<Lexem>() 

        { 

            //   // Define the lexeme to match the one character in the word 

            new Lexem() { StartText = "class",LexemType = EditTokenType.CodeSnippet, FormatName = "KeywordFormat" }, 

            new Lexem() { StartText = "def", LexemType = EditTokenType.CodeSnippet, FormatName = "KeywordFormat" }, 

            new Lexem() { StartText = "#", EndText = "#", IsRegex = false, IsMultiline = false, LexemType = EditTokenType.Comment, FormatName = "CommentFormat" }, 

            new Lexem() { StartText = "and", ContainsEndText=false, IsRegex = false, LexemType = EditTokenType.Keyword, FormatName = "KeywordFormat" }, 

            new Lexem() { StartText = ")", ContainsEndText=false, LexemType = EditTokenType.Operator, FormatName = "OperatorFormat" }, 

            new Lexem() { StartText = "(", ContainsEndText=false, LexemType = EditTokenType.Operator, FormatName = "OperatorFormat" }, 

            new Lexem() { StartText = "}", ContainsEndText=false, IsRegex = false, LexemType = EditTokenType.Operator, FormatName = "OperatorFormat" }, 

            new Lexem() { StartText = "{", ContainsEndText=false, IsRegex = false, LexemType = EditTokenType.Operator, FormatName = "OperatorFormat" }, 

            new Lexem() { StartText = "]", ContainsEndText=false, IsRegex = false, LexemType = EditTokenType.Operator, FormatName = "OperatorFormat" }, 

            new Lexem() { StartText = "[", ContainsEndText=false, IsRegex = false, LexemType = EditTokenType.Operator, FormatName = "OperatorFormat" }, 

            new Lexem() { StartText = ";", ContainsEndText=false, IsRegex = false, LexemType = EditTokenType.Operator, FormatName = "OperatorFormat" }, 

            new Lexem() { StartText = "*", ContainsEndText=false, IsRegex = false, LexemType = EditTokenType.Operator, FormatName = "OperatorFormat" }, 

        };
