LoadFormulas Method (DefaultSheetDataModel)

Loads formulas that are deserialized, but not parsed yet, to be used after all sheets have been created and deserialized.

Syntax

Visual Basic
C#

'Declaration
 
Public Sub LoadFormulas( _
   ByVal recalculate As Boolean _
)

'Usage
 
Dim instance As DefaultSheetDataModel
Dim recalculate As Boolean
 
instance.LoadFormulas(recalculate)

public void LoadFormulas( 
   bool recalculate
)

Parameters

recalculate: Whether to recalculate all the formulas in cells that have changed

Remarks

With the implementation of cross-sheet references in Spread, formulas can contain references to other sheets. If such formulas are loaded from a file, the Spread component must load sheets and formulas in a specific sequence for the cross-sheet references to work. The parsing of formulas loaded from a file must be delayed until all the sheets in the workbook have been loaded. The FpSpread.Open methods handle this automatically, loading the XML and parsing in the correct order.

If you have created custom deserialization code, then you have to be careful. If your custom code loads individual sheets and adds them to a workbook, then you will need to add code to parse the formulas after the sheet has been added to the workbook. This can be done with the FpSpread.LoadFormulas method for all the sheets in a Spread component. Using this method at the sheet level calls the method on all the data models for a particular sheet.

The code in the example below should be called after the code that loads the sheet and adds it to the workbook.

Example

This example uses the LoadFormulas method.

FarPoint.Win.Spread.Model.DefaultSheetDataModel dm = default(FarPoint.Win.Spread.Model.DefaultSheetDataModel);
dm = (FarPoint.Win.Spread.Model.DefaultSheetDataModel)FarPoint.Win.Serializer.LoadObject(typeof(FarPoint.Win.Spread.Model.DefaultSheetDataModel), "c:\\test.xml", "rootnode");
dm.LoadFormulas(true);
fpSpread1.Sheets.Count = 1;
fpSpread1.Sheets[0].Models.Data = dm;

Visual Basic

Dim dm As FarPoint.Win.Spread.Model.DefaultSheetDataModel
dm = FarPoint.Win.Serializer.LoadObject(GetType(FarPoint.Win.Spread.Model.DefaultSheetDataModel()), "c:\test.xml", "rootnode")
dm.LoadFormulas(True)
FpSpread1.Sheets.Count = 1
FpSpread1.Sheets(0).Models.Data = dm
