NamedRangeCollectionAdd Method (String, CellRange)

Adds a new named range. Named ranges are used to represent cells, ranges of cells, formulas or constant values.

Namespace:  GemBox.Spreadsheet
Assembly:  GemBox.Spreadsheet (in GemBox.Spreadsheet.dll) Version:
public void Add(
	string name,
	CellRange range


Type: SystemString
The user-defined name.
Type: GemBox.SpreadsheetCellRange
The range to be referred by name.
You can use the labels of columns and rows on a worksheet to refer to the cells within those columns and rows. Or you can create descriptive names to represent cells, ranges of cells, formulas, or constant values. Labels can be used in formulas that refer to data on the same worksheet; if you want to represent a range on another worksheet, use a name. You can also create 3-D names that represent the same cell or range of cells across multiple worksheets.

Following code demonstrates how to use formulas and named ranges. It shows next features: cell references (both absolute and relative), unary and binary operators, constant operands (integer and floating point), functions and named cell ranges. At the end, code shows how to calculate worksheet formulas.

ws.Cells["A1"].Value = 5;
ws.Cells["A2"].Value = 6;
ws.Cells["A3"].Value = 10;

ws.Cells["C1"].Formula = "=A1+A2";
ws.Cells["C2"].Formula = "=$A$1-A3";
ws.Cells["C3"].Formula = "=COUNT(A1:A3)";
ws.Cells["C4"].Formula = "=AVERAGE($A$1:$A$3)";
ws.Cells["C5"].Formula = "=SUM(A1:A3,2,3)";
ws.Cells["C7"].Formula = "= 123 - (-(-(23.5)))";

ws.NamedRanges.Add("DataRange", ws.Cells.GetSubrange("A1", "A3"));
ws.Cells["C8"].Formula = "=MAX(DataRange)";

CellRange cr = ws.Cells.GetSubrange("B9", "C10");
cr.Merged = true;
cr.Formula = "=A1*25";
