Public Property InvalidFormulaReplacementMode As FormulaReplacementMode
| Type | Description |
|---|---|
| FormulaReplacementMode |
An enumeration member that specifies how to resolve formulas with references to sheets in the source workbook. Default mode is UseExternalReferences.
|
Available values:
| Name | Description |
|---|---|
| UseExternalReferences |
Converts references to other sheets in the source workbook to external references.
| | KeepFormulaValuesOnly |
Copies only calculated values for formulas with external references.
|
When you copy a worksheet with formulas to another workbook, the Spreadsheet updates formula references in the copied sheet as follows:
Absolute and relative references to cells within the source worksheet point to the copied worksheet in the destination workbook.
References to other sheets in the source workbook are converted to external references that include the source workbook name in square brackets.
Set the InvalidFormulaReplacementMode property to KeepFormulaValuesOnly to paste only calculated values for formulas with external references.
using DevExpress.Spreadsheet;
// ...
using (Workbook sourceWorkbook = new Workbook())
using (Workbook targetWorkbook = new Workbook())
{
targetWorkbook.LoadDocument(@"Documents\Book1.xlsx");
sourceWorkbook.LoadDocument(@"Documents\Book2.xlsx");
// Add a new worksheet to the destination workbook.
targetWorkbook.Worksheets.Add("Sheet1_Copy");
// Specify copy options.
var copyOptions = new WorksheetCopyOptions()
{
InvalidFormulaReplacementMode = FormulaReplacementMode.KeepFormulaValuesOnly
};
// Copy data from "Sheet1" in the source workbook
// to the newly created worksheet in the destination workbook.
targetWorkbook.Worksheets["Sheet1_Copy"].CopyFrom(sourceWorkbook.Worksheets["Sheet1"], copyOptions);
targetWorkbook.SaveDocument("Result.xlsx");
}
Imports DevExpress.Spreadsheet
' ...
Using sourceWorkbook As New Workbook()
Using targetWorkbook As New Workbook()
targetWorkbook.LoadDocument("Documents\Book1.xlsx")
sourceWorkbook.LoadDocument("Documents\Book2.xlsx")
' Add a new worksheet to the destination workbook.
targetWorkbook.Worksheets.Add("Sheet1_Copy")
' Specify copy options.
Dim copyOptions As New WorksheetCopyOptions() With {
.InvalidFormulaReplacementMode = FormulaReplacementMode.KeepFormulaValuesOnly
}
' Copy data from "Sheet1" in the source workbook
' to the newly created worksheet in the destination workbook.
targetWorkbook.Worksheets("Sheet1_Copy").CopyFrom(sourceWorkbook.Worksheets("Sheet1"), copyOptions)
targetWorkbook.SaveDocument("Result.xlsx")
End Using
End Using
You can also use the WorksheetCopyOptions.SheetMappings property to replace external references with references to worksheets within the destination workbook. This property allows you to specify mappings between worksheet names in the source and destination workbooks.
