I am using VB.net 2008 express edition. I have figured out how to use some of the code snippets for the open xml sdk to create a drop down list of all the sheets in an excel file. I can also use the code snippet to get the value of an individual column header. What I want is a drop down list of all column headers. I could create an array containing the alphabet and loop through each column based on the alphabet letter in the array. I would then just exit the loop on the first column with no value returned for column header...but there must be an easy way to return all headers in one query of the xml.
View 5 RepliesI am exporting data from vb.net to excel and it is dropping the leading zero when its displayed on excel. How can I avoid the dropping of leading zero? I read the solution of adding a single quote but it makes my excel sheet column ugly. Also users will complain if they see a single quote on zip code field.vb.net code
Response.AddHeader("content-disposition", attachment)
Response.ContentType = "application/vnd.ms-excel"
Response.Charset = ""
the stored procedure outputs XML and it is transformed by XSLT before it is displayed on EXCEL

adding a single quote or manipulating excel sheet with column formatter (general/numbers ) etc. I don't want user to make any changes on excel to get the display properly when the excel is displayed from web page it should be all set with proper formatting. also we have no control over client excel software?

I have an asp:table which I want to exported to excel. One of my fields are alpha numeric and when exported to excel the leading 0s are stripped off. After going through this thread: Validation (CSS 2.0): 'mso-number-format' is not a known CSS property name I would like to use the css method "mso-number-format:@;.But the css is not exported to excel. I just tried to test it with simpler css things like bold font etc but its not getting carried over. I can see that if I surround my asp:Label with tags this change gets carried over to the excel but not the css bold . Other solutions in other thread does not work for me as ="00111" shows up as desired in excel but in the web form it shows up as ="00111" which is not what i want.
View 2 RepliesI need to export Chart(image) and grid (tabular) row data into excel file. I can not use automation because Office tools are not installed in my server. I've found a bunch of free/proprietary tools like:

I am working on a windows application using VB.net 2.0 and want to create a custom ComboboxControl which displays multiple groups. I was able to display the items in Custom combobox with headers. Below is the sample.
Header 1
Item 1_1
Item 1_2
[code]....
I want to prevent users from selecting the header items. I managed to revert back to the previously selected item if user selects the header item. Problem with this approach is drop down collapses and then reverts back to previously selected item. Is there a way to check, if the item being selected is a header item and if it is a header item, do not collapse the dropdown. Basically I want to implement behavior of HTML select list with optgroup.
1_1 1_2 1_3 2_1 2_2 2_3

I am using asp.net oledb to export information to excel file. I encounter problems when the information to export becomes too big, in this case the code I have given below, the excel file generated becomes an empty spreadsheet.If I changed the loop to 1123 for insertion of the rows. The generated excel file is fine, 1125 rows, and 4 columns shown.A test program in windows form is also working fine regardless of how many rows.[code]I couldn't find a solution to my problem as well. What I did eventually was to run the process using another separate windows service. The code works perfectly fine running from a windows form or service program, but not asp.net, not sure why.
View 1 RepliesI have this issue that occurs with me and driving me crazy i have a report that contains thousands of records and i need to export it to excel , but the excel normal extension .xls
is showing missing records at the end of the file , so i save my file as an .xlsx extension it saves correctly but when i open the file it generates an error
"Excel cannot open the file '<var>filename</var>.xlsx' because the file format for the file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file."but when i test the file i drag it and open it in an empty notepad all the records shows up correctly
We use a small bit of excel exporting code in our app code at work to export XML controls from our ASP pages into an excel format using the following code:
Public Shared Sub Export(ByRef xml As Xml, ByVal filename As String)
Dim response As HttpResponse = HttpContext.Current.Response()
response.Clear()
[code]....
This is all fine, except we've encountered a rather frustrating bug. If the XML control has a link in it then the export code is called again. We have a button which will say "Export to Excel" from the .aspx page which simply calls ExcelExport.Export(Xml1, "MyFileName") which is in a LinkButton click event.Here's the order of events based on the form submit (selecting filters)
Enter filters
Submit form
Page_Load occurs
[code]....
So the user submits a form which loads up the XML control in a nice viewable XSLT page. Then they click "export to excel" which will give them the page in excel instead, then they click on the XSLT page, for example a link, but the save dialog for excel comes up again. We've gone through the series of events, and if we do not call the excel exporter it goes through the series of events as normal. If we do call the excel exporter it will go through the page load event and unexpectedly go into the link button click event.

I would like to export a GridView to excel, which is easy enough. But above the grid, in Excel, I would like some other information for identification. Can I somehow export things other than gridviews while then putting in the gridview below?

Response.Charset = ""
