Custom Filters on GridView - blog example

[Rupert Henson]

Hi,

I've followed the example blog post on the subject (from 2009) and I've even downloaded the full source, recompiled in Silverlight 4 and tried running it but the Percentage Custom filter featured there does not light up even when just applied (!).

Could the example be broken somehow in SL4 / Telerik 2011.2.920.1040 that I'm currently using?


The reason I'm trying to get the example working is that I'm having difficulty getting my own Custom Filters on a RadGridView to work correctly alongside telerik default filters on other columns. I find that my custom filter works fine when used in isolation, but the minute I click into and apply a telerik standard filter on a different column, then the "IsActive" light goes out on my custom filter - despite my custom filter still being active and applied to the results (and still included in the FilterDescriptors property for the RadGridView!)

Would there be a reason why my own custom filter's "Active" light is being switched off despite no activity involving it directly?

Thanks for any help you can give me on this,

Rupert.

Hi Rupert Henson,

Unfortunately that blog post is almost two years old and is written for the state that our controls were in then. It also is for Silverlight 3.
We actually have a very good example of how to create your own custom filters in the GridView. You can see it here. I am confident that you will find the information that you need there.
However, if you have any further questions regarding this do not hesitate to contact us.

All the best,

Hi Rupert Henson,

Can you try our 2011 Q3 version, since we fixed a bug that sounds just like what you describe. If that does not help, please send us a small repro project. Thanks.

Hi Ross / Nikolay,

Thanks for your replies - I've managed to put together pretty much what I need from the newer example now.

Also the new Q3 2011 release of yesterday does appear to fix the issue I was seeing with Active Filters becoming inactive after another had been selected !

Thanks,

Rupert.
