# RightToLeft

Wisej.NET supports Right-to-Left and Right-to-Left-Layout (mirroring) quite extensively in most controls, in the themes, in the [Theme Builder](https://docs.wisej.com/theme-builder), and in the designer.

{% hint style="danger" %}
The following controls do not fully support RightToLeft at the moment: `DataGridView`, `ListView`, `PropertyGrid`.
{% endhint %}

## RightToLeft Property

The [`RightToLeft`](https://docs.wisej.com/api/wisej.web/enumerations/wisej.web.righttoleft) property makes a control adapt its internal layout and alignment for right-to-left languages. The default value is `Inherit`, which works in most cases. However, an application can:

* Force a control to ignore right-to-left mode by setting the value to `No`
* Force right-to-left mode by setting the value to `Yes`

This property is localizable.

## RightToLeftLayout Property

The [`RightToLeftLayout`](https://docs.wisej.com/api/wisej.web/containers/containercontrol#righttoleftlayout) property mirrors the horizontal position of a container's direct children. The default value is `false`.

When set to `true`, horizontal layout is mirrored only when [`RightToLeft`](https://docs.wisej.com/api/wisej.web/enumerations/wisej.web.righttoleft) resolves to `Yes`.

Set this property to:

* `false` to prevent Wisej.NET from mirroring layout in right-to-left mode
* `true` to mirror horizontal location of direct children in right-to-left mode

This property is localizable.

## Application.RightToLeft Property

[`Application.RightToLeft`](https://docs.wisej.com/api/wisej.web/general/application#righttoleft) takes its value from:

* The "rightToLeft" [Configuration](https://docs.wisej.com/docs/concepts/configuration) setting
* Can be forced to `true` or `false` programmatically

The default value of [`Control.RightToLeft`](https://docs.wisej.com/api/wisej.web/general/control#righttoleft) is `Inherit`, meaning a control inherits the value from its parent. Top-level containers and parentless controls with `RightToLeft` set to `Inherit` take their value from [`Application.RightToLeft`](https://docs.wisej.com/api/wisej.web/general/application#righttoleft).

## Themes

All Wisej.NET themes support RightToLeft mode with minimal required changes. When a widget operates in right-to-left mode, it has the "rightToLeft" state allowing theme adaptation.

Most cases need no changes. Typical right-to-left adjustments include:

* Mirroring icons
* Switching single side border location

Example of mirroring icons with a state style:

```javascript
"rightToLeft":
{
  "styles":
  {
    "transform": "scale(-1, 1)"
  }
},
```

TreeView arrows requiring 45-degree rotation when expanded and mirroring can adapt using these states:

```javascript
"rightToLeft":
{
  "styles":
  {
    "transform": "rotateZ(180deg)"
  }
},
"opened-rightToLeft":
{
  "styles":
  {
    "transform": "rotateZ(135deg)"
  }
},
```

{% hint style="info" %}
The composite state "opened-rightToLeft" qualifies styles and properties only when the widget has both states set simultaneously.
{% endhint %}
