Hi,
is it possible to select available operators for a specific property (type)? I clarify this request: I have some flags enumerations in my business objects. I would like to filter objects by these flags enumerations. If you have a flags enum with following members: First = 1, Second = 2, Third = 4. And you want to filter all objects which have value "Second" set. The default operators for enum types are "Equal" and "Is not equal". But for the flags enumerations the correct questions would be additional "contains" and "not contains". I know how to implement a DropDown with Checkboxes for specific flag selection to make a graphical representation of this question. But how is it possible to add the two more operators "contains" and "not contains" to the list of available operators? And how could I implement user defined code "behind" this operators?
Best regards,
Oliver

Hi OBollmann,
The only way that you could achieve this would be to have a custom filter template (for the whole 3-part thing, i.e. the one with the rounded corners) in addition to a custom filter descriptor, i.e. an IFilterDescriptor implementation. This will allow you to define any UI and provide any view model logic behind this UI.
Unfortunately, RadDataFilter is not mature enough and does not provide this right now. However, we have a similar feature request in our PITS system. Please, vote for it in order to increase its priority.
Let me know what you think after reading the feature description. Will this functionality solve your requirement?
Sincerely yours,

Hey Ross,
I too would like the ability to handle Flag attributes in this way. I would like to vote for this functionality, but cannot find the relevant case in the PITS system. What search criteria can I use to find it? Has it been implemented?
Thanks,
Mark

Thanks Ross! I have voted for the issue, and added a comment describing our current requirement (which is basically what this thread is describing).
