I have a Mudautocomplete that is working, my only problem is when selecting an item in the dropdown.
When I type, my SearchFunc filters the result as it should.
But when I select an item, the SearchFunc is not fired. Meaning that my filter contains more items then just the selected item.
How can I solve this to only get the selected item?
Solved it by using the bind-value property.

I need some event when my Kendo grid lose selection (no row selected).
https://dojo.telerik.com/#nick_kingston/IjIYOduw
Select one or more rows.
Filter by some field that so no selected rows show.
Expecting event appearance because now no row selected.
How to implement item 3?
There is no event like lostSelection. The change-event triggers if the user changes the selection only.
Once the filter was executed, the dataBound-event is triggered (as you can see on the demo page https://demos.telerik.com/kendo-ui/grid/events). There you could check for the list of selected items with the method select (https://docs.telerik.com/kendo-ui/api/javascript/ui/grid/methods/select)
I am using an autocomplete extender inside a gridview. Inside the gridview, I have a country dropdown. When I select a country, the states should be populated in the autocomplete extender using textbox.
I am able to populate the countries and states. But when I have multiple rows in the gridview,
I select a country in row 1 of the gridview.
But all the StatesTextbox are updated with the states based on this selection. i.e, I am not able to choose which textbox/row should be updated on Dropdown selected event.
Could anyone help me on this issue? Appreciate your response!!
I fixed this by setting the context key of the autocompleteextender to the dropdownlist selected value and retrieved the value when I typein something in the statesearch textbox.
the standard behaviour of a Flex dropdownlist is to disable the currently selected item from the list. Does anybody know how to override this to allow the user to re-select the selected item (if they so desire)?
NOTE: I don't want there to be a selected item in the list but I still want the selecteditem property to be set in the dropdownlist control, otherwise how will I know what has been selected. This is slighly trickier than it sounds...unless I have missed something...
Thanks

I'm not sure I understand the question but you can listen to close event of the component :
Dispatched when the drop-down list closes for any reason, such when the user: Selects an item in the drop-down list. Clicks outside of the drop-down list. Clicks the anchor button while the drop-down list is displayed.
So, you can access the component and gather the selectedIndex, selectedItem properties.
I guess what I'd like to know is that why you want to "re-select", possible to trigger something again but I'd try close event...
In Powerbuilder, Does anyone here know how am i going to highlights multiple items on a treeview? Selecteditem function is not doing that. Im looking for a behavior just what Selectedrow id doing.
Thanks!
I've not tried this myself but there is an example on CodeXchange (look for Multi-select TreeView Control).
I think the treeview style datawindow might be easier to do this with.
If not, I found this on the newsgroup, don't know if it helps:
The following script in the
selectionchanged event will implement
a very basic multiselect in the
treeview:
treeviewitem ltvi_item
if KeyDown(KeyControl!) then
This.GetItem(oldhandle, ltvi_Item)
ltvi_Item.Selected = True
This.SetItem(oldhandle, ltvi_Item)
end if
A problem is deselecting the
previously selected items. You would
have to scan through ALL items do look
for the selected ones (once the user
clicks an item without holding down
the control key)

One approach to this is to use the CheckBoxes attribute on the treeview, then check the treeviewitem's StatePicture (Unchecked = 1, Checked = 2).
Good luck,
Terry.
I'm using the ListPicker control from the WP7 Toolkit. I want to initially present the list with no items selected. Is there a way of doing this?
According to this blog entry List Picker works with the idea of "there is always an active selection".
The approach I would follow is to have the first item in the list be you "no selected item" item. With appropriate values (maybe a null id) that you can identify later on.
By design ListPicker must have a selected item. If you try to set it to null or set the SelectedIndex to -1 you will get an exception.
