I think you may use cell.style.background attribute to specify the backcolor of the cell in Aspose.Cells.GridWeb on client side:
.......... cell.style.backgroundColor = "yellow";
Thanks for your help.
However, is there any api can call a specifically ‘cell’ object by row and col value in client side?
(I found examples that using for loop to a grid instead of specifically one)
I think you may try to use the “this.getCell(row, column)” method to read any cell by specifying the desired row & column parameters in GridWeb.
var cell1 = this.getCell(0, 0); // get the cell "A1"
Hope, this helps a bit.
