Hi,

I have a very strange problem. The Grid below is binding very slow if I do not include Height or MaxHeight. If I do nor include one of these attributes the data appears something like 20 or 30 seconds after the ItemsSource is set. And I have only one thousand registers. If I define the Height or MaxHeight it takes less than one second.

The problem is that I do not want to pre define a Height because I want the Grid to Strech, Vertically and Horizontally, all over the page. But , of course, I want a scroll bar to appear automatically if the number of registers exceed the screen space.

How can I make it work ?

Thanks in advance
