Hi Joseph,

Thank you for using Syncfusion product.

We have validated your query and checked the provided sample. We would like to let you know that SfTextBoxExt SelectedItems type is object, but you have binded the SelectedItems property to the typeof List<Product>. So only the SelectedItem is cleared.

We have modified the provided sample please get it from below link.

Please let us know, if you have any other concerns.

according to the SfTextBoxExt class definition the SelectedItems property type is IEnumerable not an object, which means it accepts any collection type. so the question now is why it is not accepting any collection type???

in SfTextBoxExt class definition we find this???

public class SfTextBoxExt : TextBox, IDisposable {

     // IEnumerable means it accepts any collection type

     public IEnumerable SelectedItems { get; set; }

}

Hi Joseph,

Sorry for the inconvenience. Since SelectedItems is a type of IEnumerable. You have referred a SelectedItems Model inside the Model, so you can resolve this by using ObservableCollection<object> instead of List<Product>. We've modified the sample provided to get it from the link below.

Hi Joseph, 

 

Thanks for your patience. 

 

After our further analysis, as per our current implementation SelectedItems property accepts only an ObservableCollection<object>. While selecting item from the dropdown with the multi selection mode CollectionChanged event will be called instead of property setter. So when binding List of Collection it doesn’t worked. So we have logged feature request for your requirement “SelectedItems different data type binding is not working properly” that can be tracked through our feedback portal below.

Please cast your vote to make it count. We will prioritize the features every release based on the demands and we do not have an immediate plan to implement this feature since we committed with already planned work. So, this feature will be available for any of our upcoming releases. 

 

If you have any more specifications/suggestions to the feature request, you can add it as a comment in the portal. We will let you know when this feature is implemented. 

 

Meanwhile we suggest that, you to use a previously provided workaround to resolve the reported issue until then.

Hello

I just want to confirm what was said in this thread, specifically that "While selecting item from the dropdown with the multi selection mode CollectionChanged event will be called instead of property setter."

The documentation has a List<object> Selected Items and implies that the property setter is called.

Can you pls confirm that the documentation is wrong, and that it should reflect a CollectionChanged event handler?

Hi Dushan,

We have analyzed your query. In our UG, we used Listobject> for SelectedItems. That is incorrect. We will change and notify you once the changes will publish on live. We appreciate your patience until then.
