Hi

I have Radgrid with two checkboxes and details table with checkbox in one column and repeater and checkbox in it in another column. When all items in details table is checked then radgrid checkbox should also be checked. similarly if repeater items are checked then radgrid checkbox should be checked. Please suggest how can this be acheived.

<radgrid>

<mastertableview>

<Columns>

<Gridtemplatecolumn>

<checkboxleft>

</Gridtemplatecolumn>

<Gridtemplatecolumn>
<checkboxright>
</Gridtemplatecolumn>

<detailstable>

<gridtableview>

<columns>

<<Gridtemplatecolumn>
<itemcheckboxleft>
</Gridtemplatecolumn>

<<Gridtemplatecolumn>

<repeater>
<itemcheckboxleft>

</repeater>
</Gridtemplatecolumn>

</columns>

</detailstable>

</columns>

</radgrid>

Thanks for your reply. Functions that you provided will work only on those click events. But in my case I wanted those checkboxes checked/unchecked as soon as the page loads/ by default. So I tried writing javascript on document.ready function I was able to loop through  each master table row in it loop again detail table and get checkbox in details table and check/uncheck mastertable item. on left side. For right side I have a repeater in details table which has checkbox. I am having hard time accessing it. Can you please suggest how that can be done. Below is my javascript code(repeater is the class name that I gave to repeater table)(Code is working fine except at repeatertable where its always accessing first repeater in first row even though it loops through 3rd row.

$telerik.$(document).ready(function () {
           
          var masterTable = $find("<%=RadGrid1.ClientID%>").get_masterTableView();
          var count = masterTable.get_dataItems().length;
            var checkall;
            var checkalternatives;
          var item;
          
         for (var i = 0; i < count; i++) {
            item = masterTable.get_dataItems()[i];
             checkall = item.findElement("checkAll");
             checkalternatives = item.findElement("checkAllAlternates");
             var nestedView = item.get_nestedViews()[0];
             var checkeditems = 0;
             var checkedrepeateritems = 0
           var repeatercount = 0
             for (var j = 0; j < nestedView.get_dataItems().length; j++) {
                var repeatertable = 0
                if (nestedView.get_dataItems()[j].findElement("cbSelected").checked == true)
                {
                    checkeditems = checkeditems + 1;
                 }
                 repeatertable = nestedView.get_dataItems()[j].findElement("repeater")
                if (repeatertable != null) {
                    repeatercount++;
                    
                   if ($telerik.$('repeatertable input[type="checkbox"]').is(':checked')) {
                   
                            checkedrepeateritems = checkedrepeateritems + 1;
                     
                    }
                }
              
             }
             var length = nestedView.get_dataItems().length;
            if (checkeditems == nestedView.get_dataItems().length) {
                checkall.checked = true;
             }
             if (repeatercount!=0) {
             if (checkedrepeateritems == repeatercount) {
              checkalternatives.checked = true;
            }}
            }
        });
