Public ReadOnly Property Previous As CellClass

Comments
Returns the previous cell in the item's cell collection.
The previous cell is not necessarily the previous displayed cell. The CellClass.PreviousDisplayed property can be used to retrieve the previous displayed cell.
The Previous property returns the previous cell in the cell collection, CellClass.PreviousDisplayed returns the previous displayed cell.
This property traverses cells one by one, even if cells are part of a group of merged cells. To traverse groups of merged cells, use CellClass.PreviousMainCell instead.
Examples
C#
// Button part Action event
void bp_Action(object sender, ActionEventArgs e) {
// this is our button that was just clicked
ButtonPartClass bp = (ButtonPartClass)e.Part;
// this is the cell containing the button
CellClass cell = (CellClass)bp.PartOwner;
// get the previous cell
cell = cell.Previous;
// this cell's first (and only) part is a progressbar (in this example)
ProgressBarPartClass pbp = (ProgressBarPartClass) cell.Parts[0];
// increment the progressbar's Value property
int val;
if (pbp.Value == pbp.Max)
val = 0;
else
val = pbp.Value + 10; View Entire Sample Code
