Relative Panel Controls in Universal App Platform

UAP Panels is divided into the following two types:

1. Linear pattern or Panel.
2. Non-Liner pattern or Panel.

Linear Pattern

In a Linear Pattern all the controls should be either Horizontal or Vertical.

For example, a Stack Panel.


Figure 1: Stack Panel

Non-Linear pattern

In a Non-Linear pattern all the controls align in any order with relationship to other controls like top or bottom.

For example:

Child1 is top of all the elements.

Child2 is added below child1.

Child3 is added below child2, the starting position is the Child1 position.

Relative panel

Each control has a relationship with other controls with any relationship (but not a circular dependency).

A Relative Panel is a Parent control, all inside controls are child controls.

There are generally the following two types of relationships:

1. Parent to child.
2. Child to child.

Parent -> Child: All panel properties are parent types.

For example: TextBox (child control) is attached with Panel (AlignBottomWithPanel properties).



Figure 3: Child Control

Child relationship: child to child (other than panel relationship properties consider as child to child properties).

Figure 5: Panel Control

The following describes the image:

• complete box is a Relative panel.
• Inside box are child controls.
• Arrow is specified as Alignment and Position of the controls.

All the alignment properties are high-priority and the remaining (position) properties are low-priority.



Figure 6: Low Property

Each control's relation with other controls is something. If we did not provide the relative properties then the first control aligns with the default position and the next controls overwrite the previous control and always sets the relative controls. For each control one or more relationship depends on the requirements.

For example, see the following code.
