    I'm using a RadGridView in my WPF projet and when I load my form, I assign the ItemsSource property of my RadGridView to an object representing an array of values. After that, I'm trying to display a label with the number of items in my grid but the RadGridView.Items.Count method always return 0.

    Here is what I'm doing:

    RadGridView.ItemsSource; = itemsGrid //Actually, itemsGrid contain 11 elements
    GroupBox.Header = RadGridView.Items.Count.ToString(); //Always return 0.

    But I can see the 11 elements in my grid!!!
    Can you explain this???

     It will be better to bind such properties since the grid will not create everything immediately when you assign ItemsSource.

    any idea if this was ever solved ?  I need to display the custom message that has the count value of number of rows in the grid.

    I can't use the collection view that is bound to the grid as the user could have applied some column level filters on the grid.

    My collection could have 1000 items but grid might be showing only 10 based on grid filters.

    How do I get the correct number of rows being displayed on the grid.

    You can try using the Items collection of RadGridView, as the control performs all data operations, such as filtering over it.

    Hope this helps.
