The value specified will be preloaded into the last argument passed to the <a href="javascript:TL_1021533.HHClick()">UnboundColumnFetch</a> event.</p> <p>The DefaultValue property can also be used to identify specific columns in the <a href="javascript:TL_1021534.HHClick()">UnboundColumnFetch</a> event when columns are added, moved, or removed at run time.</p> <p>For bound columns or columns of an unbound grid, the grid does not use this property itself, but provides it as a placeholder for you to associate default values with the columns. In the <a href="javascript:TL_1021535.HHClick()">UnboundAddData</a> event, you can use this property to retrieve default values for columns that were not supplied by the end user. Such columns will contain a Null variant in the corresponding <em><strong>RowBuffer.Value</strong></em> property array.</p> <p>This property can also be used as a tag for a column (whether it is bound or unbound). Arbitrary values can be stored and retrieved later</p> <p>Note</p> <p>Do not confuse unbound columns with unbound mode. The DefaultValue property has no effect on data displayed in an unbound grid.</p> <h3>See Also</h3> <p><a href="JavaScript:TL_1021536.HHClick()">Column Object</a></p> <a name="seealsobookmark"></a> </div> <div id="FooterContent"> <p> </p><p> </p><hr style="height: 1px"><p>Copyright (c) <script type="text/javascript"> var theDate=new Date() document.write(theDate.getFullYear()) </script> GrapeCity, inc.
