Export ListView to Excel

by jrose 8/20/2010 10:02:00 AM

All results that I came across when performing a search for export listview to excel were related to instances of Windows.Forms.ListView and not System.Web.UI.WebControls.ListView.

 

Attached are the two functions necessary to export instances of System.Web.UI.WebControls.ListView to Excel.

public override void VerifyRenderingInServerForm(Control control) { }

protected void btnExport_Click(object sender, EventArgs e)
{
    Response.Clear();
    Response.Buffer = true;
    Response.ContentType = "application/vnd.ms-excel";
    Response.Charset = "";
    this.EnableViewState = false;
    StringWriter stringWriter = new StringWriter();
    HtmlTextWriter htmlTextWriter = new HtmlTextWriter(stringWriter);
    listView.RenderControl(htmlTextWriter);
    Response.Write(stringWriter.ToString());
    Response.End();
}

ReportViewer Control: Fit to Page

by jrose 5/11/2010 9:09:00 AM

The ReportViewer control's export functionality can be temperamental.

 

In order to guarantee that the exported file will not be wider than a page, use the following formula:

Body.Size.Width + Report.Margins.Left + Report.Margins.Right <= Report.PageSize.Width

 

(since, in our case, InteractiveSize and PageSize are the same, this means InteractiveSize can be substituted in PageSize above)
