Forms Data Controls :: Exporting Gridview Into Excel Is Not Generating The Result On Excel File?

Apr 1, 2010

when I used a code of exporting gridview into excel this code worked for a new website which is without masterpage.

my code:

public override void VerifyRenderingInServerForm(Control control) { }
protected void BtnGenerateReport_Click(object sender, EventArgs e)
{
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition",
"attachment;filename=GridViewExport.xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
StringWriter sw = new StringWriter();.....

Now the same code when I copy it in my project having masterpage . there is no compiler error but it is genereating excel file withno data in it but in fact there is data in the grid view at runtime.

Localization :: Reading A CSV File Created By Excel?

May 27, 2010

I am reading a CSV file created by Excel. the string I am reading needs to be encoded (it shows small boxes instead of hebrew characters) so I wrote a lil routine to convert the string -

Function encodeName(ByVal name As String) As String
Dim src As Encoding = Encoding.UTF8
Dim dest As Encoding = Encoding.Default
Dim srcBytes() As Byte
srcBytes = src.GetBytes(name)
Dim asciiBytes() As Byte = Encoding.Convert(src, dest, srcBytes)
Dim mychars(dest.GetCharCount(asciiBytes) - 1) As Char
dest.GetChars(asciiBytes, 0, asciiBytes.Length, mychars, 0)
Dim asciiString As New String(mychars)
End Function

From what I read FileStream.ReadLine reads the text with encoding UTF8 so I try to convert from UTF8 to Encoding.Default buy instead of little boxes I get question marks.

Databases :: Page Times Out Reading Excel File?

Mar 31, 2010

I have some code that reads records from an excel file and then imports that data into an sql database. The issue only happens when the excel file has more then 350 rows in it. In the middle of the import it just stops executing and I get directed to the 'Internet Explorer cannot display the webpage' page or just a blank page when using firefox.

I dont get any time out errors or any error at all but still I tried messing around with the script timeout settings but still does the same thing at about the 2 min 30 sec mark.

Databases :: Reading Excel File Without Saving To Disk First?

Aug 31, 2010

I need to be able to read an excel file from a file upload control but I can not save the file to disk first, it must be done in memory.

[Code]....

Above is my code for reading the data file if it IS saved to disk, but again, I have to be able to do this without saving the file to disk, it must be done in memory. I have not been able to find any sample code anywhere on how to do this from memory, everything seems to force the file be uploaded, saved to disk, and then read in the connection string, which again I can not do.

Databases :: Reading Hyperlinked Page In Excel File Using C#?

Nov 19, 2010

I understand how to use a connection string object to read excel sheets. What I don't know is how to follow a hyperlink inside excel, grab matching data from the linked page and return it to my database. Essentially, the spreadsheet has two columns:

Title | Class#

Class# has the hyperlink which links to an internal web site. The connected page has a course description and any pre-required classes that must be taken before you can take this class. This is where I'm rather stumped as I've not had to do this type of thing before.

I have made an application to read data from an excel file and save to database "Access". It's working perfect except one thing that..There are 4 columns in excel file as :
