Handling a Spreadsheet control by programming (in a window) (prefixed syntax)

Overview

A Spreadsheet control found in a window can be handled by programming.

To handle a Spreadsheet control by programming, WINDEV proposes the Spreadsheet functions.

This help page explains how to handle a Spreadsheet control found in a window by programming.

Remark: The method for handing a Spreadsheet control found in a report is different. See Handling a Spreadsheet control by programming (in a report) for more details.

Handling the Spreadsheet control by programming

Handling the Spreadsheet control

To handle a Spreadsheet control by programming, all you have to do is specify its name.

For example:

// Displays the formula bar
PSHEET_Spreadsheet..FormulaBarVisible = True

Several WLanguage functions and properties can be used to handle the Spreadsheet control.

Handling the cells of the Spreadsheet control

To handle a cell of a Spreadsheet control by programming, use the following notations:

<Spreadsheet control name>[<Row>, <Column>]

<Spreadsheet control name>["<CellName>"]

Examples:

// Colors the C1 cell in red
PSHEET_Spreadsheet[1,3]..BrushColor = LightRed

// Colors the B1 cell in green
PSHEET_Spreadsheet["B1"]..BrushColor = LightGreen

To assign a value to a cell by programming, you have the ability to use:

<Spreadsheet>.AddData.
Example: Adding a value into the "A2" cell:

PSHEET_Spreadsheet.AddData(2, 1, 12)
the direct assignment:
- via the cell.
  Example: Adding a value into the "A2" cell:
  
  PSHEET_Spreadsheet["A2"] = 12
- via the column and row of the cell.
  Example: Adding a value into the "A2" cell:
  
  PSHEET_Spreadsheet["A"][2] = 12

Remarks:

Assigning a value in 'YYYYMMDD' format to a cell in Date format automatically changes the value into date.
Assigning a value in 'HHMM' format to a cell in Time format automatically changes the value into time.

Example: Browse the cells of a Spreadsheet control:

// Browse the cells of a Spreadsheet control
sMyString is string
FOR i = 1 TO PSHEET_MySpreadsheet..NumberRow
FOR y = 1 TO PSHEET_MySpreadsheet..NumberColumn
sMyString += PSHEET_MySpreadsheet[i][y] + TAB
END
Trace(sMyString + CR)
sMyString = ""
END

Tip: Merging cells by programming

The end user has the ability to merge the selected cells via the toolbar of the Spreadsheet control.

To merge the selected cells by programming, simply use ExecuteAAF associated with the constant aafSpreadsheetMerge:

PSHEET_MySpreadsheet.SelectPlus("A1", "C5")
ExecuteAAF(PSHEET_MySpreadsheet, aafSpreadsheetMerge)

Remark: <Spreadsheet>.GetMerge is used to find out whether a cell is merged with other cells and to retrieve the range of merged cells.

Initializing a Spreadsheet control

The Spreadsheet control can be initialized with values, formulas, ... as soon as it is displayed according to different methods:

By programming, via the following functions:


Versions 20 and later <Spreadsheet>.AddData New in version 20 <Spreadsheet>.AddData <Spreadsheet>.AddData	Adds a data into a Spreadsheet control found in a window.
Versions 20 and later <Spreadsheet>.AddFormula New in version 20 <Spreadsheet>.AddFormula <Spreadsheet>.AddFormula	Adds a calculation formula into a Spreadsheet control found in a window.
Versions 20 and later <Spreadsheet>.AllowProcedure New in version 20 <Spreadsheet>.AllowProcedure <Spreadsheet>.AllowProcedure	Allows the use of a WLanguage function/procedure in a formula of a Spreadsheet control.

By loading an Excel file (in XLSX format) when initializing the control (<Spreadsheet>.Load).
Via direct input in the window editor. See Initializing the Spreadsheet control in the window editor for more details.

Managing the names of cells in a Spreadsheet control

The Spreadsheet control proposes several functions for handling the names of cells:


Versions 22 and later <Spreadsheet>.AddName New in version 22 <Spreadsheet>.AddName <Spreadsheet>.AddName	Specifies a name to identify a cell found in a Spreadsheet control.
Versions 23 and later SpreadsheetDeleteName New in version 23 SpreadsheetDeleteName SpreadsheetDeleteName	Deletes one of the names used to identify a cell found in a Spreadsheet control.
Versions 23 and later SpreadsheetListName New in version 23 SpreadsheetListName SpreadsheetListName	Returns the list of names that identify a cell in a Spreadsheet control.
Versions 23 and later SpreadsheetModifyName New in version 23 SpreadsheetModifyName SpreadsheetModifyName	Modifies the name used to identify a cell in a Spreadsheet control.

Spreadsheet control: Handling a file containing several worksheets by programming

To enable the management of several worksheets:

In the editor: In the "Details" tab of the description window of control, check "Allow the management of several worksheets".
By programming, use ..MultiWorksheet.

Once the management of several worksheets was enabled:

You have the ability to load the different worksheets of an XLSX file (<Spreadsheet>.Load).

Several functions are used to handle the different worksheets:


Versions 20 and later <Spreadsheet>.AddWorksheet New in version 20 <Spreadsheet>.AddWorksheet <Spreadsheet>.AddWorksheet	Adds a worksheet into a Spreadsheet control found in a window.
Versions 20 and later <Spreadsheet>.DeleteWorksheet New in version 20 <Spreadsheet>.DeleteWorksheet <Spreadsheet>.DeleteWorksheet	Deletes a worksheet from a Spreadsheet control found in a window.
Versions 20 and later <Spreadsheet>.InsertWorksheet New in version 20 <Spreadsheet>.InsertWorksheet <Spreadsheet>.InsertWorksheet	Inserts a worksheet into a Spreadsheet control found in a window.
Versions 23 and later SpreadsheetListWorksheet New in version 23 SpreadsheetListWorksheet SpreadsheetListWorksheet	Returns the list of worksheets found in a Spreadsheet control.
Versions 20 and later <Spreadsheet>.SelectWorksheet New in version 20 <Spreadsheet>.SelectWorksheet <Spreadsheet>.SelectWorksheet	Selects a worksheet (identified by its name) in a Spreadsheet control.

Several properties are used to handle the different worksheets:


Versions 20 and later CurrentWorksheet New in version 20 CurrentWorksheet CurrentWorksheet	..CurrentWorksheet is used to find out and modify the current worksheet in a Spreadsheet control.
Versions 20 and later MultiWorksheet New in version 20 MultiWorksheet MultiWorksheet	..MultiWorksheet is used to: Find out whether a Spreadsheet control manages several worksheets. Modify the mode for managing the worksheets in a Spreadsheet control.
Versions 20 and later NbWorksheet New in version 20 NbWorksheet NbWorksheet	..NbWorksheet is used to find out the number of worksheets in a Spreadsheet control.
Versions 20 and later WorksheetName New in version 20 WorksheetName WorksheetName	..WorksheetName is used to find out and modify the name of the current worksheet in a Spreadsheet control.

Several AAFs (Automatic Application Features) allows the user to manage the different worksheets.
