Hi qasimidl,

Thank you for posting in the community.

In order to fire the DeleteRow serverside event I can suggest that you delete the respective row on the client (on the next postback the event will be fired). For instance:

igtbl_getGridById("UltraWebGrid1").Rows.getRow(4).deleteRow()

Similarly for updating, the serverside event is fired for rows whose value has been modified on the client:

igtbl_getGridById("UltraWebGrid1").Rows.getRow(5).getCell(1).setValue("Some value")

Please note that the UltraWebGrid control is now outdated and as of .NetAdvantage 2011 Volume 2 is no longer included in our product package. I would suggest that you consider switching to the WebDataGrid/WebHieararchicalDataGrid. More information regarding these controls is available at:

Additional samples demonstrating the features of these grids can be found at:

Feel free to contact me if you have any questions.
