Hi,
How to open pdf file in the new tab or new browser in asp.net. Right now I can open the pdf file in another window but I want to open it in browser or in new tab.
The code that works to open pdf in new window is shown but I want it in new browser..
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment;filename=a.pdf");
HttpContext.Current.Response.Charset = "";
HttpContext.Current.Response.ContentType = "application/pdf";
StringWriter stringwrite = new StringWriter();
HtmlTextWriter htmlwrite = new HtmlTextWriter(stringwrite);
repeater1.RenderControl(htmlwrite);
StringReader sr = new StringReader(stringwrite.ToString());
Document pdfDoc = new Document(PageSize.A4, 50f, 50f, 40f, 40f);
PdfWriter writer = PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
pdfDoc.Open();
htmlparser.Parse(sr);
pdfDoc.NewPage();
pdfDoc.Close();
any ideas?

As per my understanding, your page is may be open on any link so set link attribute target=_blank.
OR please explain, how you are opening page?

I didn't got your question, Are you opening browser in Windows desktop application on Browser Control?
OR
Are you using Web application then you are trying to open windows/Tab?

i am using the web application. When i open the pdf file, it should either open to the next tab or new browser. Right now it is opening to the new window like the one when we open the regular pdf file from our desktop..

This is the overall code for the pdf file.
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment;filename=a.pdf");
HttpContext.Current.Response.Charset = "";
HttpContext.Current.Response.ContentType = "application/pdf";
StringWriter stringwrite = new StringWriter();
HtmlTextWriter htmlwrite = new HtmlTextWriter(stringwrite);
repeater1.RenderControl(htmlwrite);
StringReader sr = new StringReader(stringwrite.ToString());
Document pdfDoc = new Document(PageSize.A4, 50f, 50f, 40f, 40f);
PdfWriter writer = PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
pdfDoc.Open();
htmlparser.Parse(sr);
pdfDoc.NewPage();
pdfDoc.Close();

By default the links and responses would stream in the same window. You can specify a target for the link but to respect the target as a new tab/window is up to the web browser, IMHO.

I am pulling data out of a SQL database into a GridView. The column names are dynamic so I never know what they will be (except the first column).
I would like to format the data (they are floating point numbers.)
I tried to use the RowDataBound event but it doesn't seem to do anything. Is there a way to format these numbers in a {F2} format? (I know that this code doesn't do it but I have tried a ton of things and none of them worked.)
This seems like an extremely clunky way to format the data. (We cannot format the data in SQL for other reasons.)
Thx

<code>
protected void gvFcstDmd_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
int i = 0;
DataRowView drv = e.Row.DataItem as DataRowView;
for (i = 1; i < drv.Row.ItemArray.Count(); i++) // start at one to not format the first column
{
drv[i] = Convert.ToString((Decimal)drv.Row.ItemArray[i]);
}
}
}
</code>

I looked at this before. We don't know the column names (they are dates) so I cannot access the columns using Cell["Label"]. I tried to use an index to loop thru the cells but that causes the thing to eliminate all but the first row.
I must say Microsoft's documentation for this stuff is appalling.
Thx
Mark Jackson
<code>
for (i = 1; i < e.Row.Cells.Count; i++)
{
e.Row.Cells[i].Text = Convert.ToDouble(e.Row.Cells[i]).ToString("F2");
}
</code>

Got it to work. Man this seems clunky tho
<pre>
protected void gvFcstDmd_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
int i;
TableCell c;
for (i = 1; i < e.Row.Cells.Count; i++)
{
c = e.Row.Cells[i];
c.HorizontalAlign = HorizontalAlign.Right;
Double d = Double.Parse(c.Text) * 1000;
c.Text = String.Format("{0,6:N0}",d);
}
}
}
</pre>

You can use string array to retrieve the list of files from a perticular folder as :
String[] fileList=System.IO.Directory.GetFiles(@"C:\XYZ\");

hi i am currently using c# asp.net 2005.
i have a panel which is being populated by a unknown number of fileupload control.
so far it works fine, as i use a dropdownlist to populate the amount of fileupload control for the panel,
however when i click on the button to access the panel's control the panel always reset.
i read somewhere that this is cause by the post back of the button hence the controls in the button act as if they never existed.
does anyone have any solution for this they can recommend for this please?

Basically, you want to push a complete web page to a browser, but browsers are designed to pull pages.
I don't think you can send two streams like that for one display page (text + image).
However, if you programmatically create a ".mht" page, you cvould probably do what you're tryign to do. Maybe something in this article will give you an idea: Convert HTML to MHTML using ASP.NET[^]

What? No, the page is being rendered in response to a request. It's not like the web server is randomly connecting to some machine and trying to send content.
GenJerDan wrote: I don't think you can send two streams like that
There is only one stream. The images is being placed within that stream.
