The title says it all. Right now there's only a check all option. In the out of the box Grid CheckList filter the only way to clear all items for a checklist filter once filter items have been selected is to: 1) Uncheck each one individually 2) Click "Check All" to check all, then click "Check All" again to uncheck all. It would be great to just have a clear all/clear selection button in the filter list.
The functionalities listed below are officially not supported with multicolumn headers: •Frozen Columns; •Show/Hide on the client; Please provide the solution for these known issues in next release
Add support for custom paging in the RadGrid Virtualization functionality. The idea is to enable the retrieval of part of the data from the source of data instead of retrieving all of the data every time. Without this feature the optimization technique is to cache the data source. Example is available at http://www.telerik.com/support/kb/aspnet-ajax/grid/details/virtualization-and-custom-paging
The new RadGrid Filtering (Checkbox list) is great, but... 1) it will be great if, upon RadGrid Databinding, the filter gets a list of unique value for that column: that is, most of the time, how we populate the checklist. 2) Today, there's one Event "OnfilterCheckListItemsRequested" that is fired whenever a listbox needs to gets its list. Then you have to put in the event Handler the logic to find out which column called, and give back the specific column checkbox filtering list. IMO, each column should have a distinct EventHandler for this. And BTW, if in the same radgrid you mix the new filter and the old ones, the old ones get an empty box instead of the default filters with option "FilterType=checklist" Even if you choose filterType=Combined, there's a difference with the standard 'Filter way': instead of having directly the filters, you got to pass thru a single menu "filter options" to find the filter menu.
