How to undo change the cell/row values after validation fails?

The above question taken from screenshot 2.png (attached) in Sachin Jain initial post.

You can invoke UndoChanges() method on WebGridRow object such as shown in the following snippet code.

function ValidateRowCell()
{
    var grid = ISGetObject("WebGrid1");
    grid.RootTable.GetRow(0).UndoChanges();
}

Hope this helps.

Hi,

your code snippet is not working for me.

Here is my code which i added:

  function WebGrid1_OnAfterExitEditMode(controlId, tableName, editObject) {

           var grid = ISGetObject(controlId);

           var RowObject = grid.GetSelectedObject().ToRowObject();          

           var ItemId = RowObject.GetCells().GetNamedItem("ItemId");

           if (CheckValue(ItemId.Value)) {//Here Checkvalue is function, to validate the Item Value

                   RowObject.UndoChanges();

               }

  }

  RowObject.UndoChanges(); is not working.

Try to invoke ClearSelectedObject() method after calling UndoChanges(), so your code will look like following:

function WebGrid1_OnAfterExitEditMode(controlId, tableName, editObject)
{

    var grid = ISGetObject(controlId);
    var RowObject = grid.GetSelectedObject().ToRowObject();
    var ItemId = RowObject.GetCells().GetNamedItem("ItemId");

    if (CheckValue(ItemId.Value))
    {
        //Here Checkvalue is function, to validate the Item Value
        RowObject.UndoChanges();
        grid.ClearSelectedObject();
    }
}

This should helps.
