Webgrid - How to undo changes for certain cell values on a row?

The problem is that I do not want to call the controlid.AcceptAllChanges(). This would make a call to the server side BatchUpdate method, which should not be called because it would save all changes that a user has made on the grid without them physically hitting the Save button. So, this is not an acceptable solution.

How do I request this as a feature enhancement?

Hi Jocelyn,

Here is a new snippet. Hopefully it will meet your scenario. If i am not mistaken, you want to set the value back to its original before the value goes to BatchUpDate. The problem is occurred because we are using BatchUpdate, it will hold the value first and all the changes will be made when we accept all changes. So, eventhough we set value to the old value, it will not change if the accept is not be made.

function WebGrid1_OnEndRowEditing(controlId, row)
        {
            var controlId = ISGetObject("WebGrid1");
            var maxValue = 10;


            if (row.GetCells().GetNamedItem("UnitPrice").Get("Value") > maxValue)
            {
                row.GetCells().GetNamedItem("UnitPrice").SetValue(row.GetCells().GetNamedItem("UnitPrice").Get("OldValue"), true);
                controlId.AcceptAllChanges();

            }
            else
            {
                row.GetCells().GetNamedItem("UnitPrice").SetValue(row.GetCells().GetNamedItem("UnitPrice").Get("Value"), true);
            }

            return true;
        }

I hope it helps. Thank you and have a nice day.

I ran your example and it does not set the cell back to the orginal value at all when I enter a value greater than 10.

The pending changes also shows the new changes.
