ETA on documentation and few questions

[Nicolas]

Hello,

We are currently trying to decide if the ExpressionEditor can fit our needs. As such I was wondering the following:

- any ETA on the documentation?
- is it possible to customize the input lists? Could I add a custom folder (such as the Functions folder) populated with custom references, and for each of these references selected, have a custom list of values in the right list? 
- if so, is it possible to have multiple level folders in the left list?

Ex: 

+ Functions | Val1 for OBJ3A
+ My objects | Val2 for OBJ3A
     + My objects 1 |
     + My objects 2 |
     + My objects 3 |
          OBJ3A |
          OBJ3B |

Thanks

Hello Nicolas,

 We hope to be able to bring the documentation for RadExpressionEditor online this week. Please excuse us for the delay and any inconveniences it might have caused you.

 In its current version, RadExpressionEditor does not offer extensibility features like the ones you have described. We are aiming to to offer this and other features in a subsequent version, most probably our next major release in Q2, but I am unable to commit to a specific date. There is a PITS item for the feature you describe, which you will be able to find here. You may use it to track the progress of the implementation of the feature.

Thank you for the details.

Hello Nicolas,

 I apologize, the link I gave you does not work. This is the working link to the PITS item.

Has the documentation for the Expression Editor been released yet?  I'm currently working on a project, and we're trying to decide if this does enough of what we need it to do, and has the flexibility to add/disable things as we need before we proceed.  Thanks.

Hello Eric,

 Unfortunately, I still cannot comment on the release date of the documentation for the control.

 If you would list your requirements, I can talk to the team and see if any of them are supported or planned for inclusion.

Is there documentation for this control yet?

Hello Nathaniel,

The documentation for RadExpressionEditor has already been included and you can find it here. You can also run through our demos for additional reference.

What I'm asking for is documentation that explains how to use the functions in the expression editor.

For instance what is the the syntax to use the Average function.  I want the average of the values  2.3  and 3.2, how do I type that in?

Hi,

I'm re-posting the "Overview" section:

The engine that powers RadExpressionEditor enables us to parse a string into a LINQ expression, which can be consumed by any API accepting a LINQ expression.

RadExpressionEditor always generates a LambdaExpression with one parameter. The type of the parameter is inferred from the value of the Item property of RadExpressionEditor instance. For more information on lambdas, please refer to the Lambdas help topic. Here are the basic concepts of the expression engine:

• Member Access
• Function Invocation
• Constants
• Lambdas

You can check also this topic in MSDN:

Vlad those links are not helpful.  You could give me an example of how to average two numbers that I type in?  Or tell me its not possible.

Look at the attached picture, the person who put together your website doesn't understand how to use the average function either.

Started a new thread instead as this one was marked as solved...
