With the DropDown, you are dealing with one column. Whereas the DataGridDropDown could be any number of columns. It is usually linked to actual data records as opposed to just a list of values.
Such functionality is not available in the DropDown as well - both components have separate search input. Looks like you are looking for AutoComplete component.
I really need a component that does this as well -- i.e. autocomplete with a drop-down grid. It needs to allow any text to be entered (even if not in the drop-down list) and allow items in the drop down to be selected using the down arrow.
I don't quite see how to do that with the Popup component but maybe there's a way.
I'm currently using SyncFusion, which has a component that does this, but I'd really like to get rid of SF because their licensing is ridiculous. This is the one component that's keeping me from switching to Radzen completely.
Thanks. That's pretty close to what I need, but my users will complain if they can't select items by using the down-arrow. Switching to the mouse to select an item is awkward.
Ideally it should work just like the Autocomplete component works now, but show the data in a grid.
Thanks again. That looks like it will work, but the demo is currently throwing an error intermittently when you use the arrow keys, especially when there are a lot of results.
Try scrolling down a bit with the arrow keys and then back up a few times. It throws this error:
