Hello,
From your post, my understanding on this issue is: you wonder (1) How to
export contents separated with page breaks in a rdlc to *one* worksheet,
and (2) How to make the report viewer adjust the exported worksheet cell's
height to fit the content of textboxes in the rdlc. If I'm off base, please
feel free to let me know.
For you first question "How to export contents separated with page breaks
in a rdlc to *one* worksheet", I have to let you know that it is a
by-design behavior of the Report Viewer control to export the report to
several worksheets when there are page breaks in it. We are not able to
interfere with the action when the control is exporting the content to a
xls.
However, a possible solution is:
1. Set the report viewer control's ShowExportControls = False
2. Add a new rdlc which is copied from your original rdlc, then remove all
the page breaks in it so that the new rdlc will be rendered to only one
page.
3. Add a button ("Generate Excel Report") to the web page, in the button's
Click event handler, add the following:
ReportViewer rv = new ReportViewer();
rv.ProcessingMode = ProcessingMode.Local;
rv.LocalReport.ReportPath = Server.MapPath("Report2.rdlc"); //
point to the new rdlc without page breaks
rv.LocalReport.DataSources.Clear();
rv.LocalReport.DataSources.Add(...); // your report data source
Warning[] warnings;
string[] streamids;
string mimeType;
string encoding;
string extension;
byte[] bytes = rv.LocalReport.Render("EXCEL", null, out mimeType,
out encoding, out extension, out streamids, out warnings);
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.ContentType =
"application/vnd.ms-excel";
HttpContext.Current.Response.AddHeader("Content-disposition",
"attachment; filename=Report.xls");
HttpContext.Current.Response.BinaryWrite(bytes);
HttpContext.Current.Response.End();
Please have a try and let me know if it works for you.
For your second question "How to make the report viewer adjust the exported
worksheet cell's height to fit the content of textboxes in the rdlc.":
Based on my test, the cells in the worksheet generated by the report viewer
have been adjusted to the proper height. Here is my test steps:
1. Drag and drop a Textbox from Report Items Toolbox to the rdlc
2. Resize the Textbox control to 1.25in, 0.375in, and type a very long text
into it.
If I set the Textbox's CanGrow property as False, the generated report and
excel file shows the textbox as size: 1.25in, 0.375in.
If I set the Textbox's CanGrow property as True, the generated report and
excel file will adjust the textbox's height so that all the text in it can
be shown.
I am not able to reproduce the issue that "only the first line is displayed
in the generated worksheet". Am I misunderstanding your question? Or would
you send a sample to my mailbox so that I can have a clearer picture of the
problem? My mailbox: (e-mail address removed), remove 'nospam.'
