I have tables:   Output <---> ZoneOutputs <---> Zone

The grid display Outputs.  I'd like to add a column that allows me to select multiple zones from a combobox (or popup editor).  Is there a built in way to do it, and if not is there a semi easy way.  Just the display part... I think I can do the behind the scenes part of taking the checked items and turning them into ZoneOutputs (I'll probably handle it in the ViewModel as the properties change).


Image Example

Thanks,
Brian

Hi Brian,

RadComboBox does not support multiple selection. This feature is in our plans, but I am afraid it is still far from completion. We have a sample, that demonstrates how to create UI, very similar to your screenshot, please find it attached.

Hi,
Althought it is a good sample but it will be very difficult to handle when you have half dozen of multiselect combobox. so can you help to simplifiy the flow when there as many multi-select combobox. furthermore, if this functionality has been provided out of box or not yet?
Thanks

Hi Imran,

Multiselection is not provided out of the box in RadComboBox and I am afraid that we cannot suggest a simpler solution at the moment.

Kind regards,

Seems strange that Telerik's controls do not support this or even point to a template sample that can provide this.

Is it that difficult?  

Does any else in the community need this?

This is a requirement for my project, and as telerik is our "go to first " control set, I'd like to know what i'm in for. :)

And for serious, love your controls and keep up the good work!!!! 

Thanks!
Bill

Hi Bill,

Have you checked the project attached to the post from May 20? It demonstrates how you could create the template with checkbox and implement multi-selection in RadComboBox.

Hi Pankaj,

We're not aware of a way to use the ComboBox in such a scenario.  The example was created simply to demonstrate how you could implement multiple selection in ComboBox and it expects that the data type is not changed.

were you able to find solution for your issue. I also need to have multiple multi select dropdowns in my user control and all the dropdrown values are coming from different data sources? We are using MVVM .

Any help will be appreciated.

Thanks

If the text that reflects the selection is visible until you hit enter, make sure SelectedIndex="0" is there.
