Webform issue with ASP.NET 2.0.

[ffhansix]

Hi,

I have migrated a web site from .NET 1.1.4322 to .NET 2.0. After the
migration my Modal webform does not work as it did in 1.1.

The webform pops up from a page when a user clicks a button:
The following line is run in the codebehind file:

Page.ClientScri pt.RegisterClie ntScriptBlock(t his.GetType(),
"imgExportToExc el_Click", "<script
language='JavaS cript'>window.s howModalDialog( 'ExportToExcel. aspx?ClientID="
+ ddlClients.Sele ctedValue + "&FromPeriod=1& ToPeriod=" +
ddlToPeriod.Sel ectedValue + "&BudgetYea r=" + intSelBudgetYea r + "',
null,'status:no ;dialogWidth:24 0px;dialogHeigh t:150px;dialogH ide:true;help:n o;scroll:no');</script>");

Both pages that run (both the startpage and the modal webform page) has
the @page directive enableEventVali dation="false".

On the modal webform page there are two buttons (servercontrols ) cancel
and ok, if the user presses ok, some lines are executed to create an
Excel spreadsheet with the help of a third-party serverside component
(Aspose.Excel).

Extract.....
Response.Conten tType = "applicatio n/vnd.ms-excel";
objExcel.Save(S ettings.ExcelSe ttings_FileName , SaveType.OpenIn Excel,
(Aspose.Excel.F ileFormatType) intExcelVersion , this.Response);
......

The code does exactly what it should do (give the user a question,
open/save dialog for the generated Excel file) if i remove the <base
target=_self></base> from the aspx page, but then at every post i make
a new window is opened.

Could someone please help me with this issue, i have tried changing
many things but i just cannot get it to work as it did in .NET 1.1.

Sincerely

Hi,

I have sloved the problem. Instead of implementing the <base
target=_self></base> tag to get the modal webform to post to itself and
not a new window I have now changed into using an <iframe:

<iframe
src="ExportToEx cel.aspx?Client ID=<%=Request.Q ueryString["ClientID"]%>&FromPeriod=1 &ToPeriod=<%=Re quest.QueryStri ng["ToPeriod"]%>&BudgetYear=< %=Request.Query String["BudgetYear "]%>"
name="embeddedF rame" width="100%" height="100%" scrolling=no />

This works perfectly and the serverside code executes and displays the
open/save dialog when i push the Excel document to the client.

The strange thing is why my original solution worked in ASP.NET 1.1 but
not in ASP.NET 2.0 - to this I have not found an answer.
