Hi Frank,
Thank you for your interest in sync fusion products,
You can update the bulk data’s in to the grid. Please refer to the following code. Which illustrates the same.
grid.Binder.DirectSaveCellInfo = true;
try
{
foreach (GridRangeInfo range in ranges)
{
for (int i = range.Top; i <= range.Bottom; i++)
{
double currentValue = Convert.ToDouble(grid[i, range.Left].CellValue);
currentValue += value;
grid[i, range.Left].CellValue = Convert.ChangeType(currentValue, grid[i, range.Left].CellValueType);
}
}
}
finally
{
grid.Binder.DirectSaveCellInfo = false;
}
Hope this will be helpful for your reference.
