Hi,

I am exporting data from an SQL database into an existing excel file using C# and ADO.
I need to export a datatable where one of the columns is a hyperlink. I am using an OleDb update command to get the data in.


Can this be done?

So far I have tried writing the whole thing using interop but  i find it very 'clunky' and anyway I cannot get Excel installed on the server so thats out the question.

Code snippet attached.


int i=6;

            foreach (DataRow Row in BookiesData.Tables[0].Rows)

            {

               //I have an OleDB update command in here like:

 

  UPDATE [Sheet1$] SET [F5] = Row[0], F6 = Row[1]

 

           //but obviously in a C# string.

           //Say for example that i want F6 to contain a hyperlink with the URL stored in Row[1]

 

i++

 

            };

Open in new window

To create a hyperlink field insert the following string and dynamic data:

For example in vb.net  (shouldnt be hard in c#) assign the cell the value of:

"=HYPERLINK(""" & dr("Link") & """, ""Click to View"")"

You basically want to insert:

=HYPERLINK("http://www.experts-exchange.com","Click to View")

I think thats what you may be after.

regards.

Hi, thanks for the reply. Thats exactly what I am doing currently and it doesn't work. Maybe there is some setting in the Excel file or connection string needed to make it work?

Here's my query (the / character escapes the next character)

SET [F7] = '" + "=hyperlink(\"" + Row["URL"].ToString() + "\",\"" + Row["BookieName"].ToString() + "\")"

Here is my connection string:

OleDbConnection oConn = new OleDbConnection();
            string filename = Server.MapPath("~/auto/spreadsheet.xls");
            oConn.ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;
    Data Source=" + filename + @";Extended Properties=
    ""Excel 8.0;IMEX=1;HDR=YES;""";




When I open the excel file, the following string is in the cells:

=HYPERLINK("http://www.theurl.com","click here")

Any more help appreciated

Hi,

thanks for the replies

In answer to:

Try this....
1) Click on the cell
2) Then hit return
Does the cell change to a hyperlink?

The answer is YES but obviously this is not acceptable ultimately, it just shows that the outputted string is correct.

HOWEVER I HAVE FOUND A SOLUTION THAT SUITS ME

Output the URL and link text as a string to another hidden cell (e.g. F100 and F101)

And use this formula in the cell where you want the hyperlink

=hyperlink(F100,F101)

Works for me.

Cheers

"The answer is YES but obviously this is not acceptable ultimately"

The reason I asked this was because I have had in the past, the same issue and I am trying to remember how I solved it.

But you seem to have worked something out for yourself.

ALl the best.
