I need some easy/basic way to export DataGrid to Excel file and also to be able later to Import this file back to DataGrid. Nothing complicated its simple table with values amount of columns won't change.
View 5 RepliesI am working on a windows application using vb.net 2003. I am required to export my datagrid onto a excel file. I just need a button.
This is my code to populate the datagrid.
Code:
Dim connectionString As String
connectionString = "DRIVER={MySQL ODBC 3.51 Driver};" + "SERVER=localhost;" + "DATABASE=luckyspin;" + "UID=root;" + "PASSWORD=123;" + "OPTION=3"

exporting a datagrid to Excel for the last few days. I have found quite a few, mostly done through C and the ones I have found using VB have not worked out. Would anyone have a link to a good tutorial online for exporting a datagrid using vb.net? My college project is approaching its deadline quick enough.
View 7 RepliesThis code works well however when data is exported to excel in one field some values are wrong. Instead for example populating 16-12-19 it populates 43815, 01-03-99 it populates 36220. Again, if the sort code is like 20-72-68 or 60-01-22 it is populated the same way, which is correct. If the value is a date lookalike then this problem appears, but if not then the exact value as displayed on the grid is shown in excel.
I inserted the code (highlighted in red) to set all the fields as text values. Right, it is exported and when excel spreadsheet is opened the field property is text, but the problem still exists. Why doesn't excel display it as it is displayed on the datagrid and database, instead of changing it even when set text.

I am working with Vb.net and this code below works fine. However, when I review the data exported to excel I have a problem with one particular field i.e., sort code. Sort code in the database is in the format 00-00-00. Therefore if it is 12-11-09 or 11-01-66, a look alike of a valid date it is disaplyed as 12/11/2009 and 11/01/1966 in excel after the export. Excel thinks its a date which is incorrect. I expect it to show 12-11-09 and 11-01-66.

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.

I 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:

JetCell (DevTrio)
Aspose.Cells (Aspose)
But I do not know which one is better for my needs. I need to export not only grid row data but also Chart (image), thats why I am thinking about.

I like to compress the xmldata before the data is provided to the client as an excel file. I am trying to compress and deliver it as a .zip file. its not working Here's my code below. I tried compressing it, converting it to bytes etc etc. The issue with below code is, the XSL transformation is not happening properly and the output excel file is raw xml with some .net exception at the end. (that's what I see on the .xls file that's downloaded at the end) Before I started working on compression my below code was working fine that gives properly formatted excel file from the xml input. the excel file is so nice you can't even tell it was from XML.

I have done a google and see that many people have asked the question on how to export a Datagridview to a Excel (.xls) file. For some reason I cannot seem to get it to work (i have gotton the program to open an Excel and save it, all hidden in the background). I use a bit of the coding from this source code [URL] but modified it and incorporated it into my program. It connects an OLE Database connection with the excel sheet... but what i want to do is beable to alter the sheet in the datagridview and export it back to an excel sheet. I am not trying to sound pushy when i say this but... if you download the source file i am using you will get a really good idea of my situation..
