Selected sfTabItem from ViewModel

[Robert Kamarowski]

I have an sfDataGrid, and the selected item is captured by an ICommand in the ViewModel. Once I have the selected item, I want to open an sfTabItem to display the selected item details. Is this possible?

The example uses Navigation from the MainPage.xaml.cs. I would like to do this from the ViewModel, not in code behind.

I have: 

     LensesPage.xaml

     LensesPage.xaml.cs

     LensesPageViewModel.cs <-- this is where I want to call the details page from

I hope I'm making myself clear...

Hi Robert,

We have created sample based on your requirement and please find the sample from below link

Sample : https://www.syncfusion.com/downloads/support/directtrac/general/ze/TabviewDataGridNavigation1071286315

In this sample, we have added INavigation to navigate the page in view model as like below code snippet

public INavigation Navigation
{
         get { return navigation; }
         set { navigation = value; }
}

public OrderInfoRepository(INavigation _navigation)
{
      navigation = _navigation;
}  

Please check with the above sample and let us know if you have any concern.

Thank you for the example. But it goes from one page to another. I want to go from one TabItem to another TabItem. And I would like to do this from the ViewModel, not the code behind (viewpage.xaml.cs).

Hi Robert,

Thanks for the update.

We have analyzed your query created sample based on your provided information. Please find the sample from below.

We have added DataGrid control to the SfTabItem content in this sample, and when selecting the DataGrid item, the new TabItem creates and adds the selected item to the tab items.

This is exactly what I'm trying to achieve, but I'm having a difficult time getting it to work.

Your example runs from the MainPage. However, my main page has a button that is selected that goes to another page. It's there that I want to use the tab items. If I don't set the TabItemPage.xaml.cs BindingContext to the ViewModel, the ViewModel doesn't get executed. If I set the BindingContext to the ViewModel, the datagrid in the TabItemPage can't be added to the TabItems. What am I doing wrong?
