Question

I have a DataTable which I fill from a database and the in code behind I am trying to add 3 more rows after each row. Below is the code. But at the 6th line I get

Exception of type ‘System.OutOfMemoryException’ was thrown.

  for (int i = 0; i < AlldaysList.Rows.Count; i++)
    {
        DataRow row;
        row = AlldaysList.NewRow();
        DataRow row1;
        row1 = AlldaysList.NewRow();
        DataRow row2;
        row2 = AlldaysList.NewRow();

        // Then add the new row to the collection.
        row["scenarionid"] = DBNull.Value;
        row["description"] = "";
        row1["scenarionid"] = DBNull.Value;
        row1["description"] = "";
        row2["scenarionid"] = DBNull.Value;
        row2["description"] = "";
        AlldaysList.Rows.InsertAt(row, i + 1);
        AlldaysList.Rows.InsertAt(row1, i + 2);
        AlldaysList.Rows.InsertAt(row2, i + 3);
        i++;
    }

Answer 1

//This could be the problem
i < AlldaysList.Rows.Count

i think u should have a variable called int rowCount = AlldaysList.Rows.Count; before the loop..

the loop should be  for (int i = 0; i < rowCount; i++)

The reason why i say this is because if u add 3 rows inside the loop ur AlldaysList.Rows.Count is changing by +3 and u r targeting a dynamic variable instead of a static one and so it goes into the loop again and causes an exception..
