hi

the function “addRow” the following code throws the error “Error: this.obj.firstChild is null’



code snippet:



switch (menuitemId) {

        case “newContactAddress”:

            var data=memberGrid.contextID.split(”_");

            memberGrid.cellById(data[0],0).open();

            var mysubgrid = memberGrid.cellById(data[0],0).getSubGrid();

                subGridDp.setUpdateMode(“off”);

                mysubgrid.addRow(“newAddressRow”,[1,null,null,null,null,null,150,null,null,null,null,null]);

                mysubgrid.setUserData(“newAddressRow”,“stamm_ID”,memberGrid.getUserData(data[0],“stamm_ID”));

                subGridDp.sendData();

                subGridDp.setUpdateMode(“cell”);

            return true;

        break;



this happens only when i add a new row to the subgrid by clicking a topic from contextual menu from the first row in maingrid (memberGrid). else it works like a charm (e.g. clicking contextual menu in second row in maingrid).



the error is made in dhtmlxGrid/codebase/dhtmlxgrid.js, line 853

any suggestions? thx

I found out why this happend:
mysubgrid.addRow(“newAddressRow”,[1,null,null,null,null,null,150,null,null,null,null,null]);

only works, if
memberGrid.cellById(data[0],0).open();
has finished!

Since the subgrid is loaded by dynamic xml it takes too long to open the subgrid and the addRow()-functon is called before the subgrid has built the firstChild-Object.
I solved it with adding a little alert-statement which enables the grid’s open()-process to finish BEFORE the subgrid’s addRow()-function is called.
It’s a nasty work around. Would be cool to have some listener on the grid’s open()-function which runs code only, if subgrid-cell is fully opened.

Would be cool to have some listener on the grid’s open()-function which runs code only, if subgrid-cell is fully opened.
To handler if sub grid was loaded you can use onSubGridLoaded event dhtmlx.com/dhxdocs/doku.php?id=d … _to_events
