Hi

I've developed a custom language lexer for the edit control which works well.

However, I'm now trying to use the context menu options.  Most of them work as expected.  However, the comment / uncomment options don't  appear to do anything.

I cannot find anywhere in the documentation how you set what should happen when the comment line / comment selection options are chosen from the editcontrol's built in context menu.

Can anyone explain how you set what should happen when these options are clicked.

Thanks

Gavin

Hi Gavin, 
 
Thanks for your update. 
 
We have analyzed your query regarding ”Comment and UnComment option in context menu not working” . The comment and uncomment option doesn’t work for default language. For C-Sharp codes we have provided the code snippet and simple sample required to achieve your criteria. 
 
C#: 
 this.editControl1.ApplyConfiguration(Syncfusion.Windows.Forms.Edit.Enums.KnownLanguages.CSharp); 
 
 
Regards, 
Niranjan Kumar

Niranjan

I'm sorry but that doesn't work for me.  I want to apply a specific set of comment characters for my own custom language, not use the comment characters that are associated with c#.

Hi Gavin, 
 
Thanks for your update. 
 
We are currently analyzing you query “Want to apply a specific set of comment characters for my own custom language”. Can we know details regarding whether the language that you are using comes under known languages and whether only the comment and uncomment options in context menu does not work for your custom language and other options works properly? 
 
Regards, 
Niranjan Kumar

I'm writing a python editor, so all lines when commented should have a '#' in front of them. 
The other items in the context editor work fine.

Your documentation suggests that the editor can be used for an arbitrary language, so I'd assumed that you could set the comment characters somewhere.

Thanks

Hi Gavin, 
 
Thanks for your update. 
 
We have analyzed your query “Comment and UnComment option in context menu not working”. To enable the comment and uncomment actions please do the below changes in you config.xml file.  
 
C#: 
At the initialization of config language enable StartComment property by assigning your comment prefix string. 
<ConfigLanguage name="Python" StartComment="#" > 
Lexem with type comment should be added inside the lexems. 
<lexems> 
 
                <lexem BeginBlock="(" Type="Operator" /> 
 
                <lexem BeginBlock=")" Type="Operator" /> 
 
                <lexem BeginBlock="'" Type="Operator" /> 
 
                <lexem BeginBlock="car" Type="KeyWord" /> 
 
                <lexem BeginBlock="cdr" Type="KeyWord" /> 
 
                <lexem BeginBlock="cons" Type="KeyWord" /> 
                                                             
               <lexem BeginBlock="#" EndBlock="\n" IsEndRegex="true" Type="Comment" IsComplex="true" OnlyLocalSublexems="true" /> 
 
</lexems> 
 
Please refer the below sample and video for your query. 
 
 
 
Regards, 
Niranjan Kumar
