Discontinued products Uncategorized discussions
#1

Hi,

1)

in dhtmlxtreegrid the first level node has a long text. So I want to use colspan. How do I configure in script?



2)

How can I change the value of nodes in treegrid? I tried



mygrid.cellById(1,2).setValue(“New_Value”);

and

mygrid.cell(1,2).cell.innerHTML.setValue(“New_Value”);



but no success.



Thanks for help.

1) Unfortunately there is no way colspan “tree” cells
2) Fist parameter of cellById is id of a row. So you should use:
mygrid.cellById(“1”,2).setValue(“New_Value”);

1) solved with xml. OK



2) Unfortunatly it doesn’t work. There is an Error: _childindexes are Null or not an object. Is anything wrong in the attached file?



My script:



       []
        mygrid.init();



        mygrid.loadXML(“test_list.xml”);



        //change Values
        
        //sample1
        mygrid.cellById(??,??).setValue(“new_Value”);
        //sample2
        mygrid.cellById(??,??).setValue(“new_Value”);
        //sample3
        mygrid.cellById(??,??).setValue(“new_Value”);



thanks for help

cellById() method should be called only after treeGrid was fully loaded:
mygrid.loadXML(“test_list.xml”,function(){
//sample1
mygrid.cellById(??,??).setValue(“new_Value”);
//sample2
mygrid.cellById(??,??).setValue(“new_Value”);
//sample3
mygrid.cellById(??,??).setValue(“new_Value”);
});

In your xml file rows has ids: “1214”, “1213”, “1212”… So you should use:
mygrid.cellById(“1214”,0).setValue(“new_Value”);
