both dropdown lists use same data source.

when value selected in dropdownlist (outside gridview) want chaneg selectedvalue , selecttext of every dropdownlist in gridview.

this have tried:

javascript:

<script type="text/javascript"> function onjdselection() {      var jd = document.getelementbyid('dropdownlist3.clientid').selectedtext;     var grid = document.getelementbyid('gridview2.clientid');     //loop starts 1 because zeroth row header.        (var = 1; < grid.rows.length; i++) {          var othertext = grid.rows[i].cells[2].innertext; // works fine             grid.rows[i].cells[3].getelementsbyid('ddl_jd').selectedtext = jd;      } }
