# PadDirection

Padding configuration objects use this enum to decide which side of a textual value receives fill characters before a binder writes it to the control or back to the bound object. It supports the library's fixed-width formatting scenarios without hard-coding left- or right-padding behavior into each binder.

## Purpose

- Controls whether `PadArgs` expands a value from the left or the right.
- Keeps padding behavior declarative so `clsObjectBinderBase` can apply the same rule to multiple control types.


## Context

- Namespace: `SAIF.Presentation.Web.Binding`
- Assembly/package: `SAIF.Presentation.Web.Binding.Infragistics103` (embedded/bundled as source, not independently packaged)

## Public members

| Member | Signature | Purpose |
| --- | --- | --- |
| Left | `PadDirection.Left` | Adds pad characters to the start of the value before it is displayed or stored. |
| Right | `PadDirection.Right` | Adds pad characters to the end of the value before it is displayed or stored. |


## Behavioral notes

- `clsObjectBinderBase` uses `PadLeft` for `Left` and `PadRight` for `Right` when applying configured control-side or object-side padding.
- The same direction setting is reused for both outbound display formatting and inbound object assignment when the corresponding `PadArgs` target is enabled.


## Constraints and usage notes

- This enum has effect only when a binder receives non-null `PadArgs` with a positive pad length.
- Padding applies to string representations; callers should ensure added characters are acceptable for the target field semantics.
