## Detailed Description

provides access to the data of a GridControl

You can retrieve the data type information and the data in a row.

This interface allows to retrieve data even for rows which are not current, which is quite useful, as normally, you can't affect the current row in a grid control without moving the cursor of the underlying com::sun::star::form::component::DataForm.

## Member Function Documentation

## ◆ queryFieldData()

sequence<any> queryFieldData | ( | [in] long | nRow,
|  | [in] type | xType
| ) |  |

retrieves the actual column data for the given row

If a column does not support the requested type, `NULL` is returned at the respective position.

  XGridFieldDataSupplier::queryFieldDataType

## ◆ queryFieldDataType()

sequence<boolean> queryFieldDataType | ( | [in] type | xType | ) |

checks whether or not the content of the grid's columns can be retrieved in the requested format.

Not every cell content can be retrieved in every representation. For example, in a text column, you usually won't be able to retrieve the content as double.
To check if the type you need is supported by the columns, use this method.

Returns
  A sequence of boolean flags. Each flag corresponds to the respective column, and `TRUE` indicates that the column content can be retrieved in the requested format, `FALSE` denies this.
