## In This Section

- [ApplicationField Constructor](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/reference/txtextcontrol/applicationfield/constructor/llms.txt): Initializes a new instance of the ApplicationField class. The format of the parameters depends on the application that supports the field. The field is initialized without syntax check.
- [ApplicationField.Format Property](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/reference/txtextcontrol/applicationfield/format-property/llms.txt): Gets or sets the field's format. The property's value can be one of the ApplicationFieldFormat values. If the format of the field is changed, its type name and parameters must also be changed.
- [ApplicationField.Parameters Property](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/reference/txtextcontrol/applicationfield/parameters-property/llms.txt): Gets or sets the field's parameters. The order and format of the strings depend on the field's format. For example a Microsoft Word MergeField has the following format: MERGEFIELD FieldName [switches]. In this case the first string of the array is the FieldName and the following strings are possible switches. The string MERGEFIELD is the type name of the field and can be obtained through the ApplicationField.TypeName property. If a field has no parameters, this array is null.
- [ApplicationField.TypeName Property](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/reference/txtextcontrol/applicationfield/typename-property/llms.txt): Gets or sets the field's type name. For example for the type name of a Microsoft Word MergeField is MERGEFIELD. If the type name of the field is changed, its parameters must also be changed.
