The following example illustrates how to implement three different layout scenarios for different browser sizes (Small, Medium, Large):

C#

FormLayout.SettingsAdaptivity.GridSettings.Breakpoints.AddRange(new List<LayoutBreakpoint>() {
    new LayoutBreakpoint() { Name = "Small", MaxWidth = 300, ColumnCount = 1 },
    new LayoutBreakpoint() { Name = "Medium", MaxWidth = 900, ColumnCount = 2 },
    new LayoutBreakpoint() { Name = "Large", MaxWidth = 1500, ColumnCount = 3 }
});

FormLayout.Items[0].SpanRules.AddRange(new List<SpanRule>() {
    new SpanRule() { BreakpointName = "Small", ColumnSpan = 1, RowSpan = 1 },
    new SpanRule() { BreakpointName = "Medium", ColumnSpan = 1, RowSpan = 1 },
    new SpanRule() { BreakpointName = "Large", ColumnSpan = 2, RowSpan = 2 }
});

FormLayout.Items[1].SpanRules.AddRange(new List<SpanRule>() {
    new SpanRule() { BreakpointName = "Small", ColumnSpan = 1, RowSpan = 1 },
    new SpanRule() { BreakpointName = "Medium", ColumnSpan = 1, RowSpan = 1 },
    new SpanRule() { BreakpointName = "Large", ColumnSpan = 1, RowSpan = 1 }
});

FormLayout.Items[2].SpanRules.AddRange(new List<SpanRule>() {
    new SpanRule() { BreakpointName = "Small", ColumnSpan = 1, RowSpan = 1 },
    new SpanRule() { BreakpointName = "Medium", ColumnSpan = 2, RowSpan = 1 },
    new SpanRule() { BreakpointName = "Large", ColumnSpan = 1, RowSpan = 1 }
});

FormLayout.Items[3].SpanRules.AddRange(new List<SpanRule>() {
    new SpanRule() { BreakpointName = "Small", ColumnSpan = 1, RowSpan = 1 },
    new SpanRule() { BreakpointName = "Medium", ColumnSpan = 2, RowSpan = 1 },
    new SpanRule() { BreakpointName = "Large", ColumnSpan = 3, RowSpan = 1 }
});
