    <p>I am not able to download a file from a aspx page if aspx page is opened in a modal popup using window.showModalDialog().</p> <p>I have an image button on aspx page, on click of it a Excel file has been generated by using some business logic and then I add it to the Response header to make that file available for download. The code is as shown below,</p> <pre><code>Protected Sub ibtnExport_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ibtnExport.Click ... Some business logic to generate excel file. ... Response.ClearHeaders() Response.ContentType = "application/ms-excel" Response.AddHeader("content-disposition", "attachment; filename=" + someXLSFile ) Response.TransmitFile(someXLSFileWithPath) Response.Flush() HttpContext.Current.ApplicationInstance.CompleteRequest() End Sub </code></pre> <p>When I open this aspx page as a modal pop up it does not show the browser's download window. In case of normal(modeless, opened using window.open) popup download works fine.</p> <p>I have also tried using another approach for downloading files. Instead of setting response header in <code>ibtnExport_Click</code>, I have opened another aspx page, say Download.aspx, using <code>window.open</code> and set the repsonse headers on page load event of the Download.aspx. The code is as shown below,</p> <pre><code>Protected Sub ibtnExport_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ibtnExport.Click ... Some business logic to generate excel file. ... Session("$FileToDownload$") = someXLSFileWithPath ClientScript.RegisterStartupScript(GetType(String),"download","window.open('Download.aspx')",true) End Sub </code></pre> <p>And in Download.aspx,</p> <pre><code>Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim filetoDownload As String = CType(Session("$FileToDownload$"), String) Dim fileName As String = System.IO.Path.GetFileName(filetoDownload) Response.ClearHeaders() Response.ContentType = "application/ms-excel" Response.AddHeader("content-disposition", "attachment; filename=" + fileName) Response.TransmitFile(filetoDownload) Response.Flush() HttpContext.Current.ApplicationInstance.CompleteRequest() End Sub </code></pre> <p>Well, it works in case of both modal as well as modeless popup and gives a relife until you deploy the application on IIS :). Yes, this approach works on ASP.NET Development server but doesn't work on IIS.</p> <p>Any ideas, for making download work on modal popup windows?</p>

    1. COMy guess is that you've got <base target="_self" /> set on your page, you simply need to set the target of your hyperlink to _blank.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
