HeaderedContentControl

[Steven]

Hello,
In Designer form I can add Grid in
<HeaderedContentControl >
  <Grid>
  </Grid>
</HeaderedContentControl >
then add other control the grid.

How can I use code add grid?

var grid=new Grid();
grid.RowDefinitions.Add(new RowDefinition());
grid.ColumnDefinitions.Add(new ColumnDefinition());

HeaderedContentControl.Content = grid;

thank you
