Handling a Pivot Table control through programming
Overview
A Pivot Table control can be handled through programming.
To handle a Pivot Table control through programming, WINDEV proposes the PVT functions.
This help page explains how to handle a Pivot Table control through programming.
Handling the Pivot Table control through programming

Coloring the values

From the context menu of the Pivot Table control, the end user can easily color a value in order to highlight it. For more details, see Automatic features of Pivot Table controls.
Through programming, you have the ability to access the values in order to modify their style (text or background color, ...). To do so, modify the properties of values in the "Cell display" event.
For example:
// If the turnover is less than 500, displays the value in red
IF VAL_TO <= 500 THEN
VAL_TO.BackgroundColor = PastelRed
END
Remark: You have the ability to customize the style of each cell element: color, font, background color, ... via several properties. For more details, see Properties associated with the values of a Pivot Table control.

Adding a column or row title

By default, the rows or columns of a Pivot Table control have no title. You can add one using the Caption property the header name.
For example:
  • Pivot Table not displaying a title:
  • Pivot Table with a title:
The following code is used:
// Initialize PVT_Stats
COL_Continent.Caption = "Continent"
COL_Country.Caption = "Country"
COL_Vehicle_Type.Caption = "Vehicle"
COL_OrderDate_Year.Caption = "Year"
COL_OrderDate_Quarter.Caption = "Quarter"
COL_OrderDate_Month.Caption = "Month"

Making a value invisible

By default, all the values of a Pivot Table are displayed. In some cases, it may be interesting to calculate the values but not to display them. The values exist in the Pivot Table control and they can be used to perform a calculation or to fill a chart for example, ...
To hide a value, simply use the Visible property.
Example: A Pivot Table displays in each cell the turnover and the quantity sold. A chart is built from the quantity sold and this quantity must not be displayed in the Pivot Table control. To do so, use the following code line in the initialization code of the Pivot Table control:
VAL_Qty.Visible = False

Finding out and modifying the mask used to display values

To get and set the type displayed for a value in a Pivot Table control, use the InputType property. You can use the following syntax:
{{"Value Name"}}..InputType = typInputDuration
or:
ValueName.InputType = typInputDuration

Modifying the axes displayed

You have the ability to modify the axes displayed or to reverse the rows and columns with PVTAxisXY.
Example:
// Modifies the rows and columns displayed
PVTAxisXY(PVT_Stats, "COL_Year" + CR + "COL_Quarter", "COL_VehicleType" + CR + "COL_Model")

Modifying the data source

You also have the ability to modify the data source of a Pivot Table control via BrowsedFile.
Example:
// Modifies the rows and columns displayed
PVT_Stats.BrowsedFile = Stat2015
Caution:
  • If the Pivot Table control is based on a data file, the new source data file must have the same structure as the file used when creating the control.
  • If the Pivot Table control is based on an array of structures:
    • the new source array of structures must have the same structure as the variable used when creating the control.
    • the name of the new structure must be preceded by ":". For example:
      PVT_Stats.BrowsedFile = ":MyNewStructure"

Progress of calculation

  • A progress bar is displayed during the calculation of the Pivot Table control.
  • The user has the ability to cancel the calculation via a "Cancel" button.
    To find out whether the calculation was entirely performed, use the ErrorOccurred variable.
    Example:
    PROCEDURE Load_PVT()

    PVTCalculateAll(PVT_Statistics)
    IF ErrorOccurred = True THEN
    SWITCH Dialog("Do you want to cancel the current process?")
    // Cancel
    CASE 1
    Close()
    // Continue
    CASE 0
    Load_PVT()
    END
    END

Properties specific to the management of Pivot Table controls

The following properties are used to manage the Pivot Table controls:
AutoLineWrapThe AutoLineWrap property is used to:
  • determine if the automatic line wrap feature is enabled in a multiline Edit control, in a column of a Table or TreeView control or in a row header of a Pivot Table control.
  • set the line wrap mode in a multiline Edit control, in a column of a Table or TreeView control or in a row header of a Pivot Table control.
CumulatedThe Cumulated property is used to determine if the value of a column or row in Pivot Table control corresponds to a total (total at the end of a row or column).
DisplayOrphanThe DisplayOrphan property is used to:
  • Determine whether a row or column in a Pivot Table control is displayed when it has no parent.
  • Change the display mode of a row or column in a Pivot Table control when it has no parent.
FilterProcedureThe FilterProcedure property allows you to get and modify the procedure used to apply a filter on a row or column header when calculating a Pivot Table control.
ProgressBarThe ProgressBar property is used to identify and change the Progress Bar control used when calculating a Pivot Table control (PVTCalculateAll and PVTCalculateUpdate functions).
For a complete list of WLanguage properties that can be used with a Pivot Table control, see Properties associated with Pivot Table controls.
