Get Editor and Expression

[Fergal]

Hi All,

I have created a custom RadFilterDataFieldEditor to manage a specific set of my data. I need to do some additional work in code with any expressions created that are using this Editor (but only when they use a specific operator - Equal To).

Looking at the code, I can't seem to get the expression and the Editor at the same time. If I get to the RadFilterSingleExpressionItem, it has an Editor property that I can see at runtime, but is protected - so I can't access it. The Expression itself doesn't seem to have a link, and if I go in via the FieldEditors property on the RadFilter, I can get the Editors but they don't seem to have a link to the expression.

Basically, I want to do the below (aircoded):

If typeof(Editor) is MyCustomEditor and expression.FilterFunction = EqualTo Then
  'Do Custom Work
End If

Can anyone point out how to achieve this?

Thanks
Fergal

Hello,

In order to get the filter function you will need to hook the ExpressionEvaluated event as demonstrated in this help topic.

Give this approach a try and you should not have problems.
