how to generate a column in C# code for datagrid that have specific template in wpf

Question

I have this code and works good but I want to change it dynamically in C#. Can anyone help me to convert this XAML code to C# code?

Note: I set Itemsource of this datagrid in pageload of C# code

Note: I want after convert this column to C# code, change AutoGenerateColumns to true

 <DataGrid x:Name="dg" AutoGenerateColumns="False">
                <DataGrid.Columns>
                    <DataGridTemplateColumn>
                        <DataGridTemplateColumn.CellTemplate>
                            <DataTemplate>
                                <StackPanel Orientation="Horizontal">
                                    <TextBlock Text="{Binding ValueA}" />
                                    <TextBlock Text="{Binding ValueB}" />
                                </StackPanel>
                            </DataTemplate>
                        </DataGridTemplateColumn.CellTemplate>
                    </DataGridTemplateColumn>
                </DataGrid.Columns>
            </DataGrid>

Why would you want to convert that to C#? It will be much harder to maintain, and it will not improve anything. You're better off leaving it the way it is. — 15ee8f99-57ff-4f92-890c-b56153, Oct 19 '17 at 16:12
Because I want to display two values in a cell, and the number of columns varies — sadegh, Oct 19 '17 at 16:15
Why not make the DataTemplate a resource? [Here's an answer that shows how to give a DataGrid dynamic columns](https://stackoverflow.com/a/4379965/424129). — 15ee8f99-57ff-4f92-890c-b56153, Oct 19 '17 at 16:17
