Hello,I am quite new in WPF, I would like to define dynamically the grid of my aplication. I am trying to bind the number of rows and columns dynamically with next code, but what I am obtaining are parse errors . I looking for it in google and I am only finding info about how to bind values through data templates.

<Grid  x:Name="LayoutRoot" Style="{StaticResource ContentRoot}">
     <Grid  ShowGridLines="True"  x:Name="rootGrid" >
       <Style>
         <Setter Property="Grid.Row" Value="{Binding GridRow}" />
         <Setter Property="Grid.Column" Value="{Binding GridColumn}" />
       </Style>

       <Viewbox Grid.Column="0" Grid.Row="0">
         <UniformGrid x:Name="thruster_panel_port"  Margin="10">
         </UniformGrid>
       </Viewbox>

       <Viewbox Grid.Column="0" Grid.Row="1">
         <UniformGrid x:Name="thruster_panel_azimuth" Margin="10">
         </UniformGrid>
       </Viewbox>

       <Viewbox Grid.Column="1">
         <UniformGrid  x:Name="thruster_panel_bridge"  Grid.Column="1" >
         </UniformGrid>

       </Viewbox>
       <Viewbox Grid.Column="2">
         <UniformGrid x:Name="thruster_panel_stdboard" Grid.Column="2" >
         </UniformGrid>

In the cs side:

public class dynamic_Layout
    {
        int _gridRow;
        int _gridColumn;

        public int GridRow
        {

            get
            {
                return _gridRow;
            }
            set
            {
                _gridRow = value;
                if (PropertyChanged != null)
                {
                    PropertyChanged(this, new PropertyChangedEventArgs("GridRow"));
                }
            }
        }

        public int GridColumn
        {

            get
            {
                return _gridColumn;
            }
            set
            {
                _gridColumn = value;
                if (PropertyChanged != null)
                {
                    PropertyChanged(this, new PropertyChangedEventArgs("GridColumn"));
                }
            }
        }


        public dynamic_Layout(int columns,int rows) {

            this.GridColumn = columns;
            this.GridRow = rows;
        
        }


        #region INotifyPropertyChanged Members

        public event PropertyChangedEventHandler PropertyChanged;

        #endregion


    }


 public DynamicUI()
        {
             
            InitializeComponent();
            Loaded += new RoutedEventHandler(MainPage_Loaded);   
        }
        void MainPage_Loaded(object sender, RoutedEventArgs e)
        {

           dynamic_Layout _layout = new dynamic_Layout(3,4);
            this.rootGrid.DataContext =_layout;
            CreateUI();//This metod add usercontrols to the grid , in the UniformGrids.
        }

Could someone point me in the right direction?SHould I do something with the ColumnsDefinitons in XALM?
