| [DataBinding()](/engine/6000.5/script-reference/unityengine/uielements/databinding/ctor.md) | Initializes and returns an instance of [DataBinding](/engine/6000.5/script-reference/unityengine/uielements/databinding.md). |

## Properties

| Property                                                                                                           | Description                                                                                                                                                                                                                                                                  |
| ------------------------------------------------------------------------------------------------------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| [bindingMode](/engine/6000.5/script-reference/unityengine/uielements/databinding/bindingmode.md)                   | Controls how this binding should be updated. The default value is [BindingMode.TwoWay](/engine/6000.5/script-reference/unityengine/uielements/bindingmode/twoway.md).                                                                                                        |
| [dataSource](/engine/6000.5/script-reference/unityengine/uielements/databinding/datasource.md)                     | Object that serves as a local source for the binding, and is particularly useful when the data source is not part of the UI hierarchy, such as a static localization table. If this object is null, the binding resolves the data source using its normal resolution method. |
| [dataSourcePath](/engine/6000.5/script-reference/unityengine/uielements/databinding/datasourcepath.md)             | Path from the data source to the value.                                                                                                                                                                                                                                      |
| [dataSourceType](/engine/6000.5/script-reference/unityengine/uielements/databinding/datasourcetype.md)             | The possible data source types that can be assigned to the binding.                                                                                                                                                                                                          |
| [sourceToUiConverters](/engine/6000.5/script-reference/unityengine/uielements/databinding/sourcetouiconverters.md) | Returns the [ConverterGroup](/engine/6000.5/script-reference/unityengine/uielements/convertergroup.md) used when trying to convert data from the data source to a UI property.                                                                                               |
| [uiToSourceConverters](/engine/6000.5/script-reference/unityengine/uielements/databinding/uitosourceconverters.md) | Returns the [ConverterGroup](/engine/6000.5/script-reference/unityengine/uielements/convertergroup.md) used when trying to convert data from a UI property back to the data source.                                                                                          |

| [ApplyConverterGroupToSource](/engine/6000.5/script-reference/unityengine/uielements/databinding/applyconvertergrouptosource.md) | Applies a [ConverterGroup](/engine/6000.5/script-reference/unityengine/uielements/convertergroup.md) to this binding that will be used when converting data between a UI control to a data source. |
| [ApplyConverterGroupToUI](/engine/6000.5/script-reference/unityengine/uielements/databinding/applyconvertergrouptoui.md)         | Applies a [ConverterGroup](/engine/6000.5/script-reference/unityengine/uielements/convertergroup.md) to this binding that will be used when converting data between a data source to a UI control. |
