WebCombo causing postback
posted

Hi,

I am using a Ultrawebgrid with one of the column as webcombo. I want to display value of last column of grid on selection of webcombo so I have attached SelectedRowChanged ate server side causing postback. 

Whenever I click on webcmbo in any row it is causing postback, but I want to restrict postback only if I change value in webcombo of that particular row is changed

Please help on this

     Hello,
    You can use the event AfterCloseUp of  ClientSideEvents tag and force post back with JS code.


    ASXP of templated column:
    <Columns>
                            <igtbl:TemplatedColumn Width="100">
                                <CellTemplate>
                                    <igcmbo:WebCombo ID="WebCombo1" DataSourceID="SqlDataSource1" runat="server" Width="100">
                                        <ClientSideEvents AfterCloseUp="ACU" />
                                    </igcmbo:WebCombo>
                                </CellTemplate>
                            </igtbl:TemplatedColumn>

    JS cede:


     <script type="text/javascript">

       function ACU(cmboID) {

                var combo = igcmbo_getComboById(cmboID);
                __doPostBack(combo,"");
                //debugger;
            }

    </script >

    I hope this helps.
