Hi,

We are currently implementing the grid control and like the various filter options but wanted to know if someone has achieved an Excel Style Multi Select filter, similar to how the new version of the Silverlight control works? Our problem is that from the column filter dropdown, we want to be able to select ALL or nothing or pick several items that are not in a range for example option 1,3 and 9.
The silverlight control looks like it would do the trick, is there something similar out there?

Thanks in advance,
Adam

Hello Adam,

The functionality which you describe is not supported out-of-the-box by RadGrid, so you would need to implement some custom logic. The two key points are replacing the built-in menu, which approach is described in this Code Library article and then manual handling of the FilterExpression of RadGrid.

Best wishes,

We really need this filter option.  I'm surprised this is not an included option as having a row of textboxes or dropdowns below the Header text is not very UI friendly.   The excel way of filtering is the cleanest approach.    Has anyone done this code?  I need to implement this.

Hello Brian,

Have you considered using RadFilter to allow more flexible filtering for RadGrid? This way you will not need to perform the custom logic requred by the other approach:
Filter / RadGrid filtering with RadFilter

That is very nice for advanced users.  Unfortunately, for non-advanced users they are familiar with excel filtering and it also does not add to the space the UI needs.   It's very clean for the UI.

Brian,

What did you ever do about this?

Telerik is still using filter bars, if you can believe it. (in ASP.NET AJAX anyway).

In the Q3 2013 they have added Excel-like multi-check selections in the dropdown.   I have not implented it yet but pretty nice addition.   I believe it is still in the filter row though.   Progress!

Brian,

Shouldn't we be able to add that to this:

http://demos.telerik.com/aspnet-ajax/grid/examples/generalfeatures/headercontextfiltermenu/defaultcs.aspx



take a look at the 'ship city' column,,,,imagine that being a dropdown arrow instead.

And, viola,,,if it works.
