Hi!

I need some help. I need to copy checked records from grid1 to grid2, by clicking a button. Grid1 has allowpagination = true.

I have problems when I change page, cause I lose records selected on another pages.

Also I need to copy to Grid2 selected records in other pages, not the actual page.

Thanks in advance.

<script type = "text/javascript">
     function Check_Click(objRef) {
         //Get the Row based on checkbox
         var row = objRef.parentNode.parentNode;
 
         //Get the reference of GridView
         var GridView = row.parentNode;
 
         //Get all input elements in Gridview
         var inputList = GridView.getElementsByTagName("input");
 
         for (var i = 0; i < inputList.length; i++) {
             //The First element is the Header Checkbox
             var headerCheckBox = inputList[0];
 
             //Based on all or none checkboxes
             //are checked check/uncheck Header Checkbox

             if (inputList[i].type == "checkbox" && inputList[i] != headerCheckBox) {
