Select a row from ViewModel

[Roy Halvorsen]

How do I select a spesific row from my ViewModel (we're using mvvm pattern and no codebehind)? I have tried several approaches with no luck. Tried to set SelectedItem, tried to set CurrentItem, IsSynchronizedWithCurrentItem true/false. Nothing seems to help. Debugging the ViewModel shows that the row is selected, but the Gui is not updated.

Hi Roy Halvorsen,

I have attached a sample project which demonstrates how you can bind RadGridView's SelectedItem to a ViewModel and change the SelectedItem from the ViewModel itself.

Hope it helps.

Kind regards,

Can we access the SelectedItem from ViewModel? The example used it from code behind.

Hi Hui,

In the attached demo application, indeed, the value of the SelectedItem property is changed on a button click in the code behind. Please, however, take a closer look, that the property is actually defined in the view model and the SelectedItem property of RadGridView is bound to it. You have a direct access to the SelectedItem property in the view model and can update it as per your requirements.

I meant  Click="Button1_Click" is in code behind.

I want to it in ViewModel to handle the property.

Hello Hui,

The way to go  is to use an ICommand. You may find the Basic MVVM and ICommand  Usage Example article useful on the matter.

Hope this helps.
