asp.net: combobox or listbox PLUS checkbox

i need a solution like this:

http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/checkboxes/defaultcs.aspx

however, i need the user to be able to add entries in here.

does such a c开发者_高级运维ontrol already exist?

it can be either jquery or asp.net

it also does not have to be a combobox, it can be a listbox. i need to have every item have a checkbox next to it and be able to add a comment for each entry.

Take a look at the ASPxGridLookup control from the DevExpress component vendor.

The ASPxGridLookup component allows the implementation of the multi-select DropDown functionality:

with editing capabilities via the embedded ASPxGridView object:

To me it sounds like it might be better for you to run with a ListBox. Telerik offers the RadListBox, which allows you to have checkboxes as seen here.

Additionally, you could allow for edits upon, for example, double-click as is displayed in the source code attached to this forum post.

Finally, if you want to also display the comments then you could use an ItemTemplate to define a custom layout for each RadListBoxItem and allow the user to edit both the main and comment fields.

That should cover everything that you need.
