SelectedValue and SelectedItem

[Mark]

I have a Telerik RadCombobox where I need to react to the change of selected item and store the selected value.

telerik:RadComboBox ItemsSource="{Binding CurrencyList}"<br>  DisplayMemberPath="Currency"<br>  SelectedValuePath="CurrencyID"<br>  SelectedValue="{Binding SelectedIssuance.IssuanceCurrencyID, Mode=TwoWay}"<br>  IsSynchronizedWithCurrentItem="True"<br>  SelectedItem="{Binding SelectedCurrency,Mode=OneWayToSource}"

This works the first time I access the view, however subsequent accesses on the same or another record the displayed value is always the first record in the CurrencyList

Any suggestions on how to fix this issue?

One idea is to get the changed value in the VM from the Model by subscribing to the OPC event and remove the SelectedItem binding.

Hello Mark,

Looks like you are using one property in the ViewModel for the SelectedValue and SelectedItem, so it doesn't work as expected. You would need two separate properties in order to achieve the desired - please check the attached sample project. For more details regarding the SelectedValue and SelectedValuePath, you could check the following article:
http://docs.telerik.com/devtools/wpf/controls/radcombobox/features/selection#using-selectedvalue-and-selectedvaluepath

Hope this helps.
