Setting ControlTemplate in code [WPF] - wpf

Question

How can I set Grid object with some UI elements in ControlTemplate? I try use this code, but I don't understand how to set Grid object to FrameworkElementFactory object. Thanks
ControlTemplate CellControlTemplate = new ControlTemplate(); // my control template
Grid CellGrid = new Grid(); // my grid (I want add it to my control template
FrameworkElementFactory root = new FrameworkElementFactory(typeof(Grid));
// ???
CellControlTemplate.VisualTree = root;
I need it for replacing my xaml-designed style in code behind:
<Style TargetType="{x:Type igDP:CellValuePresenter}" x:Key="PStyle">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type igDP:CellValuePresenter}">
<Grid Margin="4">
<Grid.RowDefinitions>
<RowDefinition />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Row="0" Grid.RowSpan="2" Grid.Column="0"
FontWeight="DemiBold"
FontSize="18"
VerticalAlignment="Center"
Text="{Binding Path=DataItem.DINAMIC_COLUMN}"/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
I must do it, because I want change binding path for textbox in runtime from code. Do you know others ways? Thanks.

Here is solution:
var grid = new FrameworkElementFactory(typeof(Grid));
// assign template to grid
CellControlTemplate.VisualTree = grid;
// define grid's rows
var r = new FrameworkElementFactory(typeof(RowDefinition));
grid.AppendChild(r);
// define grid's columns
var c = new FrameworkElementFactory(typeof(ColumnDefinition));
grid.AppendChild(c);
//... etc
Thanks all.
