Managing Ranges

Introduction

In Excel, you can select multiple cells with a mouse box selection, the set of selected cells is called “Range”.

For example, you can click the left mouse button in Cell “A1” of the Excel and then drag to cell “C4”. The rectangular area you selected can also be easily created as an object by using Aspose.Cells.

Here is how to create range, put value, set style, and do more operations to the “Range” object.

Managing Ranges Using Aspose.Cells

Aspose.Cells provides a class, Workbook that represents a Microsoft Excel file. The Workbook class contains a Worksheets collection that allows access to each worksheet in an Excel file. A worksheet is represented by the Worksheet class. The Worksheet class provides a Cells collection.

Create Range

When you want to create a rectangular area that extends over A1:C4, you can use the following code:

	//Create a Workbook
	Workbook workbook = new Workbook();
	//Get Cells
	Cells cells = workbook.getWorksheets().get(0).getCells();
	//Create Range
	Range range = cells.createRange("A1:C4");

Put value into the Cells of the Range

Say you have a range of cells that extends over A1:C4. The matrix makes 4 * 3 = 12 cells. The individual range cells are arranged sequentially: Range[0,0], Range[0,1], Range[0,2], Range[1,0], Range[1,1], Range[1,2], Range[2,0], Range[2,1], Range[2,2], Range[3,0], Range[3,1], Range[3,2].

The following example shows how to input some values into the cells of the Range.

	//Create a Workbook
	Workbook workbook = new Workbook();
	//Get Cells
	Cells cells = workbook.getWorksheets().get(0).getCells();
	//Create Range
	Range range = cells.createRange("A1:C4");
	//Put value
	range.get(0, 0).putValue("A1");
	range.get(0, 1).putValue("B1");
	range.get(0, 2).putValue("C1");
	range.get(3, 0).putValue("A4");
	range.get(3, 1).putValue("B4");
	range.get(3, 2).putValue("C4");
	//Save the Workbook
	workbook.save("RangeValueTest.xlsx");

Set style of the Cells of the Range

The following example shows how to set style of the cells of the Range.

	//Create a Workbook
	Workbook workbook = new Workbook();
	//Get Cells
	Cells cells = workbook.getWorksheets().get(0).getCells();
	//Create Range
	Range range = cells.createRange("A1:C4");
	//Put value
	range.get(0, 0).putValue("A1");
	range.get(3, 2).putValue("C4");
	//Set Style
	Style style00 = workbook.createStyle();
	style00.setPattern(BackgroundType.SOLID);
	style00.setForegroundColor(Color.getRed());
	range.get(0, 0).setStyle(style00);
	Style style32 = workbook.createStyle();
	style32.setPattern(BackgroundType.HORIZONTAL_STRIPE);
	style32.setForegroundColor(Color.getGreen());
	style32.setBackgroundColor(Color.getRed());
	range.get(3, 2).setStyle(style32);
	//Save the Workbook
	workbook.save("RangeStyleTest.xlsx");

Get CurrentRegion of the Range

CurrentRegion is a property that returns a Range object that represents the current region.

The current region is a range bounded by any combination of blank rows and blank columns. Read-only.

In excel, you can get CurrentRegion area by:

Select an area(range1) with the mouse box.
Click “Home - Editing - Find & Select - Go To Special - Currect region”, or use “Ctrl+Shift+*”, you will see excel automatically helps you select an area(range2), now you made it, range2 is the CurrentRegion of range1.

Using Aspose.Cells, you can use “Range.CurrentRegion” property to perform the same function.

Please downloaded the following test file, open it in excel, use the mouse box to select an area “A1:D7”, then click “Ctrl+Shift+*”, you will see area “A1:C3” selected.

current_region.xlsx

Now please run the following example, see how it works in Aspose.Cells:

	//Create a Workbook
	Workbook workbook = new Workbook("current_region.xlsx");
	//Get Cells
	Cells cells = workbook.getWorksheets().get(0).getCells();
	//Create Range
	Range src = cells.createRange("A1:D7");
	//Get CurrentRegion
	Range A1C3 = src.getCurrentRegion();
