Hello Mainak,

The grid's EditItems collection contains the items (rows) of the grid that are currently being edited. When using EditForms or PopUp however, the items in the collection are the items in their initial (unedited) form. To access the edit form for an item in the list, use its EditFormItem property.

Please refer to this help topic for more information how to achieve the desired by you functionality.

Kind regards,

Hello Mainak,

The new values which the user entered before triggering the Update command can be fetched calling the ExtractValuesFromItem method. You can review the help topic below which elaborates on how to retrieve the old / new values for the edited item:

Hi,

This code also , i have tried as follows..

  Hashtable newValues = new Hashtable();
               e.Item.OwnerTableView.ExtractValuesFromItem(newValues, editedItem);


But for me newValues is coming as null object.

Please send me if you have any sample code to get only the updated value in popup item. same as my pasted code.
I dont want any Database related update, only how to get updated value.
If possible , please review my code and send me as zip file.
Please...

Thanks ..
