Public API Changes in Aspose.Cells 8.7.1

Added APIs

Added LookInType.OriginalValues Property

Aspose.Cells APIs already support the Find or Search Data feature for spreadsheets in order to find some particular piece of contents in cell value & formula. However, this feature was lacking the aspect of formatting applied onto the cell that may change the appearance as well as the value of the contents, consequently make the text unsearchable using the original value. With this release of Aspose.Cells APIs, another constant by the name LookInType.OriginalValues has been exposed to the public API which allows to overcome the situation as discussed above.

Following is the simple usage scenario.


 //Create workbook object

Workbook workbook = new Workbook();

//Access first worksheet

Worksheet worksheet = workbook.Worksheets[0];

//Add 10 in cell A1 and A2



//Add Sum formula in cell D4 but customize it as ---

Cell cell = worksheet.Cells["D4"];

Style style = cell.GetStyle();

style.Custom = "---";


//The result of formula will be 20

//but 20 will not be visible because

//the cell is formatted as ---

cell.Formula = "=Sum(A1:A2)";

//Calculate the workbook


//Create find options

FindOptions options = new FindOptions();

options.LookInType = LookInType.OriginalValues;

options.LookAtType = LookAtType.EntireContent;

Cell foundCell = null;

object obj = 20;

//Find 20 which is Sum(A1:A2) and formatted as ---

foundCell = worksheet.Cells.Find(obj, foundCell, options);

//Print the found cell


Added OnBeforeColumnFilter Event for GridWeb

Aspose.Cells.GridWeb for .NET 8.7.1 has exposed the OnBeforeColumnFilter event which serves as callback to the filtering mechanism done through the GridWeb UI. As the name suggests, the event is triggered before the column filtering is applied and can be used to get the filtering information such as column index and value on which filter has to be applied.

Simple usage scenario looks as follow.


 protected void GridWeb1_ColumnFilter(object sender, Aspose.Cells.GridWeb.RowColumnEventArgs e)


    string msg = "Column index: " + (e.Num) + ", Filtered Value:" + e.Argument;
