Hi,

I am using auto loading in treeGrid. How do I pass additional info to server beside

   nodeid:rc.id,<br />   n_left:rc.lft,<br />   n_right:rc.rgt,<br />   n_level:rc.level,<br />when a node is clicked by operators?<br /><br />This links (http://www.trirand.com/jqgridwiki/doku.php?id=wiki:treegrid#cautions_and_limitations)<br />also mentions that additional info is needed but does not show me how. Look under "<a id="cautions_and_limitations" name="cautions_and_limitations" target="_blank" rel="nofollow">Cautions and Limitations" section.</a><br /><br />Correct me if I am wrong but postData does not work either because you have to wait for the row to be clicked before you can <br />fish out the additional data to be sent to server. Otherwise, you don't have the rowid to begin with.<br /><br />Thanks.<br /><br /><br />

Hello,

Thanks. Will see how to fix this.

Also just for the record, what kind of additional information do you want to add to the postData?

Best Regards

Tony

Hi Tony,

Thanks Tony. I need to send back to the server the primary key of the record being searched so that I can query the path leading to the record being searched like this:

SELECT parent.name<br />FROM nested_category AS node,<br />nested_category AS parent<br />WHERE node.lft BETWEEN parent.lft AND parent.rgt<br />AND node.name = 'FLASH'<br />ORDER BY parent.lft;<br />

1	SELECT parent.name<br />FROM nested_category AS node,<br />nested_category AS parent<br />WHERE node.lft BETWEEN parent.lft AND parent.rgt<br />AND node.name = 'FLASH'<br />ORDER BY parent.lft;<br />
