How to enable "Contains" logical operator when filter custom property?

[King Chan]

Hello Telerik Staff,

I am filtering a custom property whichs contains multiple value, by following this blog I could successfully poplulate custom distinct values and filter by the distinct vlaues, as well as enable the <, <=, >, >= operator for comparsion.
But still, the "Contains", "Begin with" etc logical operators are missing and I would like to implement it into the default filter editor control from Telerik.
Is it possible? If so, how?

Thanks in advance,
King

Hi,

Maybe this blog post can give you a head start.

But that would require to implement a Custom Filter Control.
Our design is to have all column using default Telerik Filter Control, so we don't want to implement single column's Filter Control UI differently.
So other than implement a Custom Filter Control, is it possible for us to implement the filter logic and enable it on the default Telerik Filter Control?

Hello,

I am afraid that you would have to implement a custom filter control to achieve this custom functionality.

Ok, thanks.

Hi,

You could take our default XAML and make your custom filtering control look like the stock one. But you will have to implement all the custom code-behind logic because it is custom.
