Dynamically Add Columns to Grid in silverlight

ColumnDefinition column = new ColumnDefinition();
column.Width = System.Windows.GridLength.Auto;

layoutRoot.ColumnDefinitions.Add(column);

layoutRoot.Children.Add(btnTest);
Grid.SetColumn(btnTest, (layoutRoot.ColumnDefinitions.Count-1));

In Silverlight, if we want to dynamically add controls to our page, we may think in this way:

• <Grid> : so we can add columns, rows by using Grid.SetColumn(<elementToAdd>,<columnNumber>)

• <StackPanel>: So we can set the orientation (Vertical or Horizontal) of the elements we add in that stackpanel

• <Grid> and <StackPanel> can add other grids or stacks inside them using <…>.Children.Add(..)  method.
• Also take a look at the post  How to find all Textboxes on a Silverlight page for more helpful tips.
