In Devexpress I have a Bar Manager with different items in it such as buttons and combobox's. My combobox is a BarEditItem with a EditValue that is bound to the selected object.
The combox then has ComboBoxEditSettings which has a binding to a database.
Is there a way to set a sort of the itmes in the combobox to alphabetical? I know i can sort in my call to the database but I do not want to do this option, all I want is my combobox to be bound and the sorted before showing.
Is this possible??

I am trying to create an item that is a button "show more" and when you press on it you can show a kind of context menu / drop down that all of the items in that drop down are with checkboxes and there is a search component in it too, so you can search some items in the dropdown by their name. For example: (instead of "c++,c#,Object c" it's should show "show more", i.e. static text)
I tried to use kendoContextMenu. But I don't know if it's could work because the problem with context menu is that when I will click on a checkbox the menu will close. Please advise me of a way to do that or if you have an example of code. Thanks!
The MultiSelect component might be a good starting point
https://docs.telerik.com/kendo-ui/api/javascript/ui/multiselect.
My understanding is that MultiSelect does not have a "select more than one at a time in dropdown" feature.
You might consider using a pop up window and within that implement your own custom ui that features everything you want
search term box
scrolling list of selected and selectable items
accept or cancel changes in selection
Regarding your dojo that extends drop down list, I can't code the extension for you. However, changing the dataSource assignment to a setDataSource call will populate the extension component according to the template.
// kendo.ui.DropDownList.fn.dataSource = options.testItemSource;
me.setDataSource(options.testItemSource);
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.
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)
https://groups.google.com/forum/#!msg/powersoft.public.powerbuilder.objects/B2ulHBrSnrs/itwhNBjlyOoJ
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 have a datagridview on a windows form. It has clolumn [EmployeeNumber, EmployeeName and EmployeeDepartment].
I want to be able to edit values directly in the grid but i want EmployeeDepartment to be a combobox column, such that on cell edit, a combobox shows up with available options for the employee department. Has any one been able to implement such functionality?
The DataGridView actually has a DataGridViewComboBoxColumn. If you go to the column designer, and add a new column you'll notice you can select one of a few types. It behaves exactly as you have described - on edit, it appears. The DataGridView uses things called editing controls, and has various events for swapping the control into the cell on edit.
Either way, if all you want is a drop-down, that's available out of the box.
To populate the combo box with items, in the column editor you will notice that it has an Items property for manually setting items, or you can use the data binding properties: DataSource, DisplayMember, ValueMember. Data-binding has issues when an expected value is not in the items collection, you will get a lot of cell errors; but they can be avoided.

I haven't been able to successfully bind some test data to a SketchFlow ComboBox. I added a sample data source and created a collection with some basic string values. There are a number of tutorials on how to bind to a ListBox in SketchFlow and that works fine, just not finding anything for a ComboBox.
One thing that caught me out a few times is that you need to have your data in "list mode" before you drag it on to the control (combo box or list box).
It seems to work as I expected, so perhaps I'm not understanding your issue correctly, but I'll give it a shot! I created a sample DataSource with a couple of strings in it, added a ComboBox to the layout root and then just dragged the Collection from the DataSource and dropped it on the ComboBox.
Keep in mind that if you drag the DataSource itself, you'll only be setting the DataContext property of the ComboBox and that's not enough to get your items to display. You also need the ItemsSource bound to the Collection of the DataSource and an ItemTemplate or a DisplayMemberPath to tell the ComboBox how to display your items.
Additionally, if you use the drag and drop method of binding, it will use the ItemTemplate approach for you, which may or may not be what you want as it will generally create a StackPanel and display all fields from the row in your Collection per item in the ComboBox. You can remove the ItemTemplate and set DisplayMemberPath to whichever field you wish to have displayed from your data source's collection.
