Also, OnChange event is used to be invoked from Client-side. Therefore, it does not trigger any events from Server-side. Since we need to pass through Server-side in order to retrieve the database, this scenario is most likely not recommended to be implemented.</p> <p>Hope this helps. Thank you.</p> <p> </p> <p>Regards,</p> <p>-Martin-</p>http://www.intersoftsolutions.com/Community/WebGrid/How-to-retrieve-data-from-dropdown-combo/Mon, 22 Nov 2010 21:18:09 GMTindah.ai@gmail.com<p>Dear IS,</p> <p>I have a case about retrieving data when onchange events occured for a dropdownlist combo in your WebGrid.<br />This case might be not recommended, but the User want it to be.<br />I have tried the Unbound way once to solve this, <br />but since the grid is in Hierarchical mode, we must use ISDataSource, <br />which is on its inserting/updating process, all data that has been set on grid, must be saved.</p> <p>This case described as below.</p> <p>In a grid, there are 4 columns.<br />Columns A : NewRowEditType/EditType="DropdownList"<br />Columns B, C, D : Default</p> <p>When Columns A onchange, system will retrieve data from Master to be set on Columns B and C.<br />This must be set, because User need to have a default data from Master.<br />And when it necessary, User is able to change some data that has been retrieved.<br /></p> <p>Any idea how to handle this?<br /></p>
