Alert when a new record is added on a page

[phytos]

i have a custom web application that retrieves data from the database for orders that are not completed. i have the page to auto refresh every 1 min. I would like to find a way to alert with a popup msg when a new order is added on the datagrid.


Thanks in advanced

Save the record count to ViewState (or Session) then check if it changes on PostBack, using RegisterClientScriptBlock to cause the prompt:

if( !IsPostBack )
{
int recordCount;

//determine recordCount

ViewState["records"] = recordCount;
}
else
{
int newRecordCount;
int oldRecordCount;

oldRecordCount = (int)ViewState["records"] );

//determind new record count

if( oldRecordCount != newRecordCount )
{
Page.RegisterClientScriptBlock("AlertScript",
"<script language='javascript'>alert('record count changed')</script>");

//update record count in ViewState
ViewState["records"] = newRecordCount;
}
}
