Currently, I've designed my own combobox from a ListBox/Button/TextBox to accomplish this, but I'm finding this to be way to much work to try and get a hacked together ComboBox to look like an actual ComboBox control.
This does however give me the desired effect however. Sort of ...
But my question is, is there not a simpler way to do this? Is there a way to simply right click on an item in a ComboBox, and get a context menu that says "Delete" for that specific entry?
Here is an example of the desired effect with my hacked together ComboBox:
I've tried simply linking a ContextMenu to a ComboBox, but that only allows for right click on the actual ComboBox itself, not the drop down, which renders this useless to me.
Any help or advice would be greatly appreciated.

I have a combobox field in the screen and i need to call an event when i click on save button after typing a new text in this combobox field which is not currently available in the dropdown list.
My seniors told me to use focusout event to get this, but i don't know how to get this.
I am using combobov.vue to show dropdown
Please help me out.
I am able to fix issue by using #blur. Thanks everyone for the comments, especially Boussadjra Brahim
I have a pretty simple form that brings up a certain record when the "caseNumber" is selected from the combobox. Although after a selection is made within the combobox, it will freeze the entire form on the record selected. I can't click on any other text boxes or buttons. I have to stop the debugger. No errors are thrown. I've read where this has happened to others, but no answers to the problem, that I can find.
There is no code behind it so far, as the form is bound to a dataset and should just bring up the rest of the information once the caseNumber is selected.
Changed the "Selected Value" dropbox to "none" on the data binding menu for the combobox.
Under DataBindings, go to Advanced and make sure DataSource update mode is on NOne
A lot of times this happens because there is a problem in the binding. Are you sure it's not binding the text value of the control(the combobobox) to the data?
The correct way to bind (under DataBindings, Advanced) was to bind it to the SelectedValue instead of Text.
Please let us know a little bit more how your combobox is binded.
Embarrassingly, I think I am missing something rather simple here but I just can't seem to figure this out. I'd would like a calculated field to appear in the subform header or footer, but I can't even get it visible.
I checked the property sheet settings of the subform and it clearly states: "Form Header--visible. Display When--always".
Appreciate any help in this unnecessarily frustrating matter.
When you right click on the detail, make sure you've selected Form Header/Footer, not Page Header/Footer
Not OP's issue, but this might help other newbs like myself.
Make sure you have selected a suitable default view, such as single or continuous form.
I am currently implementing drag and drop using the DataGrid provided in the Silverlight SDK and I want the user to be, easily, able to drag multiple items to another list.
The grid's selection gets updated on the MouseDown event so the only way the user have to drag multiple items is to press Shift while begining the drag operation. This is not really obvious and, for me, the natural way whould have been to just click the selected block of rows and drag them. To do so, the selection needs to be updated on the MouseUp event.
I've tried to derive from the DataGrid to inject my custom DataGridRows but the DataGrid doesn't expose a way to replace the type of rows it creates.
Anyone have a solution or ideas for this?
Thank you,
Jacques.
Yes, it's unfortunate that the selection is updated on mousedown. You will need to perform some work in the mousedown event to work around this. This codeproject article should help:

I am creating a web control in vb.net that contains a list box. I know that I am able to choose a selection mode of Single or Multiple, but I am interested in limiting a Multiple selection to a predetermined size. For example preventing a user from selecting more than 3 items.
I have tried adding a Validator to the list box, which might be a way forward, but was wondering if there was a way of changing the selection mode to something a bit different than just the two specified ones.
Any ideas or suggestions would be greatly appreciated
Edit: Unfortunately due to project limitations I am unable to use Javascript on this problem. very annoying I know!
You could try handling one of the SelectedIndexChange events. With multiple selection, each time this event fires you can check how many items have already been selected. If it is more than you want, have the handler deselect the one that was just selected. You could also put up a little red label under the listbox saying "Sorry, no more than [n] selections allowed."
EDIT:
Just noticed you said WEB. Same theory applies, but it would have to be done using Javascript.
On the SelectedIndexChanged event, write a short piece of code that will check the number of selected items and if it is greater than your desired amount, unselect the new selection (or unselect the oldest one, or however you wish this to operate).
