Split grid in UWP code

How can I split the grid? I mean, how in a designer with RowDefinitions and ColumnDefinitions? Here's my code:

composite = (Windows.Storage.ApplicationDataCompositeValue)roamingSettings.Values["enabledDays"];
            ColumnDefinition column = new ColumnDefinition();
            column.Width = new GridLength(20, GridUnitType.Star);
            grid.ColumnDefinitions.Add(column);
            try {
                foreach (KeyValuePair<string, object> MonthBool in composite) {
                    if ((bool)MonthBool.Value) {
                        column.Width = new GridLength(100, GridUnitType.Star);
                        grid.ColumnDefinitions.Add(column);
                    }
                }
            }
            catch (Exception) {
            }

But I get the error "No installed components found. The item is already a child of another item" when it tries to add another column. What can I do? How do I split the grid?

So I figured out from the error message that I am trying to add the same item (duh), so I just need to create a new object:

column = new ColumnDefinition();


So my code now looks like this:

    composite = (Windows.Storage.ApplicationDataCompositeValue)roamingSettings.Values["enabledDays"];

    ColumnDefinition column = new ColumnDefinition();
    column.Width = new GridLength(20, GridUnitType.Star);
    grid.ColumnDefinitions.Add(column);

    try {
        foreach (KeyValuePair<string, object> MonthBool in composite) {
            if ((bool)MonthBool.Value) {
                column = new ColumnDefinition();
                column.Width = new GridLength(100, GridUnitType.Star);
                grid.ColumnDefinitions.Add(column);
            }
        }
    }
    catch (Exception) {
    }
