function AmountCalculation(Grid, Quantity, PricePerUnit, Amount, subtoal) {

debugger;

var Grid = $find(Grid);

var Quantity = $find(Quantity).get_value();

var PricePerUnit = $find(PricePerUnit).get_value();

var Amount = $find(Amount);

var subtotal = $find(subtoal);

Amount.set_value(Quantity * PricePerUnit);

Hello,

This method give sum of particuler column.

You can also do like...

<telerik:GridTemplateColumn >
                                                    <ItemTemplate>
                                                        <telerik:RadNumericTextBox ID="txtImpression" runat="server"
                                                            IncrementSettings-InterceptArrowKeys="false"
                                                            IncrementSettings-InterceptMouseWheel="false" MinValue="0" NumberFormat-DecimalDigits="0"
                                                            ClientEvents-OnError="onErrorOccur" onchange="javascript:CalculateCurrentlyAssigned(this);"
                                                            gname="txtImpressions" GroupName='<%# Eval("Name") %>'>
                                                        </telerik:RadNumericTextBox>
                                                    </ItemTemplate>
                                                </telerik:GridTemplateColumn>

function CalculateCurrentlyAssigned(obj) {
                    var SumImpressions = 0
                    $("input[gname='txtImpressions']").each(function () {
                        if ($(this).val() == '') {
                            $(this).val(0);
                        }
                        SumImpressions = SumImpressions + parseInt($(this).val().replace(/,/gi, ""));
                    });
}

by this code you can get sum of RadNumericTextBox's value. by using jquery

or

If you want to get particular row's controls in client side then check below link

Hi Bhumesh,

Please try the below code to get the rows count.

ASPX:

<telerik:RadGrid ID="RadGrid1" runat="server" >

<MasterTableView>

<Columns>

. . . . . . . .

</Columns>

</MasterTableView>

<ClientEvents OnRowClick="RowCount" />

</ClientSettings>

</telerik:RadGrid>

JS:

<script type="text/javascript">

function RowCount() {

var grid = $find("<%=RadGrid1.ClientID %>");

var MasterTable = grid.get_masterTableView();

var Rows = MasterTable.get_dataItems();

alert(Rows.length);

}

</script>

Thanks,
Princy
