Hi,



How we can change the row position of child row in a treegrid.

I have written two function at dhtmlxgrid.js

that takes the child row to the top and bottom of his relevant parent

this.moveRowTop=function(row_id){

         var r = this.getRowById(row_id);

         var childpos = this.rowsCol._dhx_find®;

         var childparentid=this.getParentId(r.idd);

         var pr = this.getRowById(childparentid);

         var parentpos = this.rowsCol._dhx_find(pr);

         var no=parentpos+1-childpos ;

        return this.moveRowUDTG(row_id, no);

    }

this.moveRowBottom=function(row_id){

         var r = this.getRowById(row_id);

         var childpos = this.rowsCol._dhx_find®;

         var childparentid=this.getParentId(r.idd);

         var pr = this.getRowById(childparentid);

         var parentpos = this.rowsCol._dhx_find(pr);

         var noofchild=this.hasChildren(childparentid);

         var no=parentpos+noofchild-childpos ;

         this.moveRowUDTG(row_id, no);

}

    

But it is not working. please provide me some sample code for this. I have to do a child fc on the top or bottom of its relevant parent depending on situation.



Its very urgent for our product.

You can use

as last child
grid.moveRowTo(rowId, targetId, “move”, “child”);

as first child
grid.setDragBehavior(“sibling-next”);
grid.moveRowTo(rowId, targetId, “move”, “sibling”);

Hi,



I have written  the code below but it doesnot work in case of move up. In that case we need to change the order of a row so the rowis and target id is same. Please help me. 



mygrid.moveRowTo(rowid, rowid, “move”, “sibling”);

Hi,



I am also facing the same problem. The simple form of my situation:
The grid has only one parent.
Under this parent there are 5 children i.e Total of 6 rows - 1 parent and 5 children
I am writting a button on click of which, the selected row should become the first child.



PARENT ROW
    CHILD #1
    CHILD #2
    CHILD #3
    CHILD #4
    CHILD #5



If I select row “CHILD #3” and then click the button, the grid should change to:
PARENT ROW
    CHILD #3
    CHILD #1
    CHILD #2
    CHILD #4
    CHILD #5



In the above similar fashion, I’m creating button to move selected row to the bottom i.e the result would become:
PARENT ROW
    CHILD #1
    CHILD #2
    CHILD #4
    CHILD #5
    CHILD #3



Note: my grid implementation is WITHOUT dragndrop support. (with my implementation, user should not be allowed to do dragndrop of rows)



Thanks.
