Exporting to Microsoft Excel from a DataView Web Part consuming a Web Service with Parameters

Question

In Sharepoint Designer, I've developed a page displaying a DataView Web Part which consumes an XML Web Service with three parameters.  These parameters are passed in from a simple Form Web Part containing three input fields.  I am able to provide default values for the web service so the dataview is initially populated, and when I enter in new parameters, the web service goes back, grabs the requested data and displays in the dataview nice and slick.
The problem I'm having is this: In Internet Explorer 7, when I right-click on the DataView Web Part and select Export to Microsoft Excel, Excel opens up, says "ExternalData_1: Getting Data..." and returns the data from the web service which applies to the default parameter values each and every time, regardless of whether I have changed the parameters on the web page, and contrary to what the DataView Web Part displays on the screen.
Has anyone else run into this, and is there a solution to the problem?
Best regards,

Hi Bullish35,
 It's possible to provide single export button and export your 4 dataview webparts. Here's the modified code.
<Script Language="Javascript">
function isIE() // Function to Determine IE or Not
return /msie/i.test(navigator.userAgent) && !/opera/i.test(navigator.userAgent);
function exportToExcel() // Function to Export the Table Data to Excel.
var isIEBrowser = isIE();
if(isIEBrowser== false)
alert('Please use Internet Explorer for Excel Export Functionality.');
return false;
else
var strTableID1 = "detailsTable1", strTableID2 = "detailsTable2", strTableID3 = "detailsTable3", strTableID4 = "detailsTable4";
var objExcel = new ActiveXObject("Excel.Application");
var objWorkBook = objExcel.Workbooks.Add;
var objWorkSheet = objWorkBook.Worksheets(1);
var detailsTable = document.getElementById(strTableID1);
var intRowIndexGlobal= 0;
for (var intRowIndex=0;intRowIndex<detailsTable1.rows.length;intRowIndex++)
for (var intColumnIndex=0;intColumnIndex<detailsTable1.rows(intRowIndex).cells.length;intColumnIndex++)
if(intColumnIndex != 3)
objWorkSheet.Cells(intRowIndexGlobal+1,intColumnIndex+1) = detailsTable1.rows(intRowIndex).cells(intColumnIndex).innerText;
intRowIndexGlobal++;
for (var intRowIndex=0;intRowIndex<detailsTable2.rows.length;intRowIndex++)
for (var intColumnIndex=0;intColumnIndex<detailsTable2.rows(intRowIndex).cells.length;intColumnIndex++)
if(intColumnIndex != 3)
objWorkSheet.Cells(intRowIndexGlobal+1,intColumnIndex+1) = detailsTable2.rows(intRowIndex).cells(intColumnIndex).innerText;
intRowIndexGlobal++;
for (var intRowIndex=0;intRowIndex<detailsTable3.rows.length;intRowIndex++)
for (var intColumnIndex=0;intColumnIndex<detailsTable3.rows(intRowIndex).cells.length;intColumnIndex++)
if(intColumnIndex != 3)
objWorkSheet.Cells(intRowIndexGlobal+1,intColumnIndex+1) = detailsTable3.rows(intRowIndex).cells(intColumnIndex).innerText;
intRowIndexGlobal++;
for (var intRowIndex=0;intRowIndex<detailsTable4.rows.length;intRowIndex++)
for (var intColumnIndex=0;intColumnIndex<detailsTable4.rows(intRowIndex).cells.length;intColumnIndex++)
if(intColumnIndex != 3)
objWorkSheet.Cells(intRowIndexGlobal+1,intColumnIndex+1) = detailsTable4.rows(intRowIndex).cells(intColumnIndex).innerText;
intRowIndexGlobal++;
objExcel.Visible = true;
objExcel.UserControl = true;
</Script>
I haven't tested this. But it should work! :)Regards,
