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:



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");




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




newInput = 0.0;



function VarianceTotal(sender, args) {


newInput = sender.get_value();


Thanks for your help.
