We allow the users of our application to move rows, in the TreeGrid, up and down. We would like to persist the order of the rows when we do a POST. So, how can I get the DataProcessor to pass the rowIndex of the TreeGrid row it is updating?



Looking at the parameters that are set I see



Request parameters : gr_id value : 402 which is the grid rowID

Request parameters : gr_pid value : 401 which, I believe, is the grid row parentId



It seems like I need to do something like this:

rowIndex = getRowIndex(gr_id)



Will that work? If so how do I get the DataProcessor to pass that back to the server?



Thanks,



Andrew

The rowIndex is pretty flexible parameter, it can be changed by lot of different operations ( for example sorting will change indexes of all rows in grid )



By default dataProcessor doesn’t sent such information to server side but you can change default logic, by next code modification



dhtmlxdataprocessor.js , line 414



str+="&"+pref+“gr_pid=”+this.escape(this.obj.getParentId(rowId));



can be rewritten as



{
     str+="&"+pref+“gr_pid=”+this.escape(this.obj.getParentId(rowId));
     str+="&"+pref+“gr_index=”+this.escape(this.obj._h2.get[rowId].index);

}
