I've create a ContexMenu, and the option allow the user to clear the all item in the DataGrid. All working so good, but I want to optimize the algorithm with one method, in particular I want do this:

  1. User go in one of three DataGrid and press right mouse button, delete the option in this table

  2. A method starting the method, this method should do this:

    • Check which table has fired the events, get the DataGrid name and delete all rows of the DataGrid that have fired the events. This is my code XAML CODE:

      ContextMenu x:Key="Squadre_ContextMenu">
    <MenuItem Header="Pulisci Tabella" Click="ClearTable_Click">
    </MenuItem>
</ContextMenu>

C# CODE method calling:

private void ClearTable_Click(object sender, RoutedEventArgs e)
    {
        Console.WriteLine(((DataGrid)sender).Name.ToString()); //exception returned...
        //datagrid.ClearValue();
    }

and in a class I've the property function:

 public static void removeRows(DataGrid name passed by parameter)
    {
        var grid = parameter passed;
        var mygrid = parameter passed;

        if (grid.SelectedIndex >= 0)
        {
            for (int i = grid.SelectedItems.Count - 1; i >= 0; i--)
            {
                mygrid.Items.Remove(grid.SelectedItems[i]);
            };
        }

        grid = mygrid;
    }

NB: datagrid variable is an instance of the class DataGrid datagrid = new DataGrid(); this class contains the function for delete all the rows.

Why bother passing the name of the grid? Why not just pass the grid itself to the function and operate on it that way?

    private void ClearDataGrid(DataGrid aDataGrid)
    {
        // clear aDataGrid's contents here
    }

Just call the function, and pass the DataGrid you want to clear to it.

You can use the following information to determine what control was clicked on:
