IList.numRows

Gets the number of rows in this list.

Syntax

public int 
numRows()

Description

The numRows method returns the number of rows in a list.

If the list represents uncached data in a database, a large delay and high memory usage might be encountered, since the list must be scanned on the database side to determine the count. Avoid this if possible.

Returns

Returns the number of rows in the list.

Example

try
    {
        for (int i=1; i <= treelist.numRows(); i++)
            {
                treelist.moveTo(i);
                DeleteTopic(treelist.getValue(Msg.nid));
            }
    }
