Dynamically Added MultiSelect Combobox

[Farrel]

Hi there,

I've made use of the following multi selection combobox - http://www.telerik.com/support/code-library/a-multiselect-combobox.

However, the difference in my implementation is that the control is dynamically added via the code-behind.

My implementation changes are:

- DataTemplates (for SelectionBoxTemplate and ItemTemplate) are stored in XAML page inside the resources.
- Data Binding is done differently, dynamically added to the control when created.

Issues encountered:

- Lag with interaction between control and data binding.
- Unable to programmatically set the display text of the box on a 'dropdownclosed' event

Any help will be appreciated!

Hello Farrel,

I'm afraid that the multiple selection ComboBox scenario is not supported, so the the project you are referring to might misbehave in a specific scenarios. What I can suggest you would to check the AutoCompleteBox control which is designed to support multiple selection and provides many other helpful features. You can find the AutoCompleteBox online demos on the following link:

Hope this helps.

Hi there Kalin,

Sadly... the multiple selection option in the AutoCompleteBox is not what I'm after. I'm looking for an implementation where a user can multi select via some checkboxes.

Hi Farrel,

I'm afraid that currently the AutoCompleteBox control is the only available option as the ComboBox doesn't support multiple selection out of the box and such modifications might lead to unexpected behavior.

If you have any other questions let us know.
