Hi I'm trying to update multiple records on the list page when a button is clicked. The button global on the page and not in the data grid. I'm using this example from the manual but I keeping getting errors. The strange thing is that the database is updated with the new value. I'm open to suggestions as well.
for (int i=0; i < keys.Count(); i++)
{
// set ReportsTo field to 'Bob Smith'
string sql = "Update employees set ReportsTo='Bob Smith' where KeyField=" + keys[i]["KeyField"].ToString();
tDAL.CustomQuery(sql);
}
result["txt"] = "Records were updated.";
This is the error that I'm getting
Server Error in '/AAConvert' Application.
