Hello

It is not possible to set a value in the CurrentRow property directly to prevent FocusedRow from being changed.

I believe that you can use a static dispatcher to accomplish this task:

Silverlight

public object CurrentRow {

get { return currentRow; }

set {

prevRow = currentRow as DataItem;

DataItem item = value as DataItem;

currentRow = value;

RaisePropertyChanged("CurrentRow");

Application.Current.RootVisual.Dispatcher.BeginInvoke(() => {

if(item.Id % 2 == 0)

CurrentRow = prevRow;

});

}

WPF

public object CurrentRow {

get { return currentRow; }

set {

prevRow = currentRow as DataItem;

DataItem item = value as DataItem;

currentRow = item;

RaisePropertyChanged("CurrentRow");

Dispatcher.CurrentDispatcher.BeginInvoke(new Action(() => {

if(currentRow != null && currentRow.Id % 2 == 0)

CurrentRow = prevRow;

}));

}

Whoo hoo! It's getting there! This means I can gut out a lot of my custom code that reads data annotations which is a good thing. I love throwing out code.

It would be great if the grid had knowledge of CollectionViewSource (see Q223251), including its sort descriptors, grouping, and filtering. Then we can finally have a true separation of behavior and presentation.

That's nice! But can you show how to bind to FocusedRow property and I need logic in ViewModel property to prevent FocusedRow changing? Some thing like that:

CurrentRow

{get{...}

set{

if(currentRow.HasErrors())

return;

currentRow = value;

RaisePropertyChanged(........);

}
