                    <s:columns>

                              <s:arraylist>

                                        <s:gridcolumn datafield="sequrank" headertext="sequence" sortdescending="true"></s:gridcolumn>

                                        <s:gridcolumn datafield="coeff" headertext="coeffiecent"></s:gridcolumn>

            </s:datagrid>

 

 

basically want sort coeff in desending order want data in seqrank move accordingly.

 

thanks help

 

 

p.s managing populate datagrid need sort thanks

do sort on "gridrank" before populating grid.

 

here 1 way of doing it.

// create sort instance. var mysort:sort = new sort();                  // set sort field; sort on last name first, first name second. var sortfieldrank:sortfield = new sortfield("sequrank", descendingsort); mysort.fields = [sortfieldrank];  // apply sort collection. gridrank.sort = mysort; gridrank.refresh();  

 

if not sorting columns together.
