Add or remove lexems

Dynamically we can change the lexems by add or remove the lexemes by using Lexem.Add or Lexem.Remove methods.

C#

//Removing Lexems from the language
this.editControl1.Language.Lexems.Remove(objconfigLex);
//Changing the lexems
objconfigLex = new ConfigLexem(this.TextBox1.Text, "", FormatType.Custom, false);
objconfigLex.IndentationGuideline = true;
objconfigLex.FormatName = "HighLight";
//Add it to the current language's Lexems collection
this.editControl1.Language.Lexems.Add(objconfigLex);
//Reset the current configuration language cache to refelect these changes
this.editControl1.Language.ResetCaches();

 

VB

'Removing Lexemes from the language
Me.editControl1.Language.Lexems.Remove(objconfigLex)
objconfigLex = New ConfigLexem(Me.TextBox1.Text, "", FormatType.Custom, False)
objconfigLex.IndentationGuideline = True
objconfigLex.FormatName = "HighLight"
'Add it to the current language's Lexemes collection
Me.editControl1.Language.Lexems.Add(objconfigLex)
'Reset the current configuration language cache to reflect these changes
Me.editControl1.Language.ResetCaches()
