RadGridView lines Count

[Ala eddine]

could not count lines in RadGridView
i used this code :
_________________________________________

var query = from m in _Context.Modules

              select m;

 

var count = query.Count();

radGridView1.ItemsSource = query;

label1.Content = count;

__________________________________________

label1 shows 0 even where radGridView1 has some items

Hello Ala eddine Boukhris,

You need to execute the query and make sure that the items are loaded. Then you can work directly with Items collection of the grid and get its count (this.myGrid.Items.Count).

i tryed again with this code
___________________________
 

ModuleContext _context = new ModuleContext();

radGridView1.ItemsSource = _context.Modules;

LoadOperation<Module> op = _context.Load(_context.GetModulesQuery());

i used
label1.Content = op.Entities.Count();
and
label1.Content = radGridView1.Items.Count;

but i have 0 shown evrytime!!!
