    Okay - I am updating a textbox named txtRequested which is then updating a textbox named txtVariance in the same row.  When txtVariance is changed the OnChangeValue is fired and I need to now update the footer with the new value.  footer = footer + newValue.  How can I do this in javascript? 

    This is the code I am using to get the variance:

    function

     

    Variance(sender, args)

     

    {

     

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

     

     

    var cell = sender.get_element().parentNode.parentNode;

     

     

    var index = cell.parentNode.rowIndex;

     

     

    var MasterTable = rdgrid.get_masterTableView();

     

     

    var row = MasterTable.get_dataItems()[index - 2]; //getting row

     

     

    var tbxAdopted = row.findControl("tbxAdopted").get_value(); //getting value of TextBox 'tbxAdopted'

     

     

    var tbxReq = row.findControl("tbxReq").get_value();

     

     

    var Variance = tbxReq - tbxAdopted;

     

     

    var tbxVariance = MasterTable.get_dataItems()[index - 2].findControl("tbxVar");

     

    tbxVariance.set_value(Variance);

    }

    this gets the value of the textbox changed in the variance column:

     

    var

     

    newInput = 0.0;

     

     

    function VarianceTotal(sender, args) {

     

    newInput = sender.get_value();

    }



    Thanks for your help.
