Filter Restricted to One Column

[kencox]

I'm trying to use the RadFilter to work around the following limitation:

"RadGrid's filtering does not support "Between" FilterFunction when the RadGrid is bound to the EntityDataSource."

What I need is a Filter showing only one field (Date) that appears on startup. Much of the Filter UI should be hidden, including the TimePickers. I've attached a picture of what the desired result.

Any ideas how I can build a stripdown version of the RadFilter like this?

Thanks,

Hello Ken,

In order to achieve your goal, I suggest that you try implementing a custom filter template similar to the one used for the same purpose in this demo.
Other than this, you can add RadFilter in the grid column FilterTemplate with a predefined filter expression. The handle the server-side ItemCommand event to cancel the addition of other expressions.

Kind regards,

Hi Iana,

Thanks for your response.

I've made some progress on removing the unwanted filter items. However, I need help on making one filter item appear automatically when the Filter loads. I don't want to require the user to click anywhere to make it appear.

Is there a method or property I can set to make one item visible at all times?

Thanks,

Ken

Any help here?

How can I add a predefined filter expression and make it visible when the RadFilter appears?

Hello Ken,

Check the attached sample illustrating how you can add default expressions for RadFilter.
Give it a try and let me know if any issues arise.
