Get the checked items of a CheckListBox

[Fabio Henrique Baptista]

Hi,

How can I get the items that are checked in my CheckListBox, I tried SeletecItem property, connected with a List <>, but had no success.

ps. I'm using MVVM.

thanks

Hi Fabio,

Thanks for contacting Syncfusion Support.

Since CheckListBox has been inherited from MultiSelector, its SelectedItems Property is Hidden and ReadOnly. So using the SelectedItems in MVVM is not possible.
But we can achieve your requirement by two ways,

First way:
Include bool property, say "IsSelected" in Model level and bind this property with IsSelected of CheckListBoxItem. This can be done by modifying the ItemsContainerStyle of Control. And then while the property changes, write your codes to preserve SelectedItems.

Second Way: Including either AttachedProperty or Behavior
Here we need to provide new attached property to hold the selected items of control. Unlike previous way, this will support full XAMl binding in MVVM.

We have created a demo sample that tries to explain above methods. You can download the sample from the below location.

Sample:
CheckedListBox_Sample


Please let us know if the sample helps or in case of any other query.

Dear Muthukumar,

I want to use the CheckListBox control in a simple dialog window.

I am not using MVVM.

I require that only a single item can be selected.

Can you recommend a way to do this?

Hi Andy, 

 

Thanks for your update. 

 

We suspect that your requirement is to check only one item from CheckListBox control at a time, if so we have prepared a workaround sample to meet your requirement in which we have changed the “IsSelected” property of the previously checked item to false once new item has been checked in SelectionChanged event of the CheckListBox control and it can be downloaded from the below location. 

 

Sample: CheckListBox_Sample
