custom function for previewFormat

[Bridge24]

Hi, I just discovered your filter component and that's exactly what we need for bridge24.com.

I tried it in that dojo, to find how I can use it with custom data source (users, ...), change the operators, add new types, ... and it works fine.

You can see my tests there

https://dojo.telerik.com/@foxontherock/iYelAJiP/4

There is 1 thing I was unable to do, it's use a previewFormat for values that are array of id, exemple "users" (multi) in my example.

Data values are [1,3], an array of "id". 

Is it possible to use a function in the previewFormat property, to return usernames instead of useridin the expressionPreview property?

Thank you.

Hello,

 

I am afraid that currently using a function for previewFormat is not available. Nevertheless, you can submit a feature request in our feedback portal.

Thank you.  If I can't set a function, now I need to just dont't show some specific items.

Is there a format I can use to always return empty?

Hello Frederic,

 

The previewFormat option can be set to a valid format string. If an invalid value is used it will be ignored. 

If you would like not to show the filter expression I suggest setting the expressionPreview option to false.
