Index of visible selected row

[Marc Weintraub]

I'm working with a gridview that has a CellTemplate with a CheckBox column and I'm able to set the IsEnabled value using the following code.

    IList<CheckBox> cbks = myGridView.ChildrenOfType<CheckBox>().ToList<CheckBox>();
    MyObject selectedProject = myGridView.SelectedItem as MyObject;
    int SelectedIndex = myGridView.Items.IndexOf(selectedProject);
    cbks[SelectedIndex].IsEnabled = True;
 
 
This works great, but except ChildrenOfType<>() only provides the rows for visible rows. I can not set EnableRowVirtualization to False.

 

How do I get the index of the visible row that is within the List of checkboxes (chks)?

 
Thanks in advance.

Hi Marc,

My recommendation would be to count on bindings instead. What you can try is to bind IsEnabled property of the CheckBox through a converter (IValueConverter) and set it to true/ false depending on your custom logic.
Will that approach fit into your requirements ?

Thanks for the reply.

Unfortunatly, as it sits, I'm unable to bind it to a property. There are other factors, then a simple value, that enables/disables that checkbox.

Can you provide an example of using the IValueConverter for use with custom logic?

Hi Marc,

Could you provide a bit more details about your exact scenario ? When do you want to enable/ disable a specific CheckBox ? What will that depend on ?
