DataSource Controls :: How To Export The Current DataSet Bound To A Gridview To Excel
Mar 12, 2011
I have a GridView populated by an ObjectDataSource. I also have several DropDownLists filtering the ObjectDataSource. I found a link providing a way to export a DataSet (or DataTable) to Excel here:
http://msmvps.com/blogs/deborahk/archive/2009/07/23/writing-data-from-a-datatable-to-excel.aspx
ow I can ensure that filters applied to the ObjectDataSource when the method is called are applied. In short, how can I ensure what the UI is displaying is what the file will include when exported?

What I would like to do is ALTER the dataset for the Parent (dropdown list - ddlRT). I need to format and disable certain topics. I have a script I create before I added the datarelations.

I am using the following code to export fields from a database table into excel. What I want to do is be able to write a SQL statement to retrieve fields from multiple tables and export them into excel. This code only allows me to export one table. Also, how can I display a save prompt dialog?
protected void export_Click(object sender, EventArgs e)
{
string sql = null;
string data = null;
string path = save_as.Text;
int i = 0;
int j = 0;
Excel.Application xlApp;
Excel.Workbook xlWorkBook;
Excel.Worksheet xlWorkSheet;
object misValue = System.Reflection.Missing.Value;
xlApp = new Excel.ApplicationClass();
xlWorkBook = xlApp.Workbooks.Add(misValue);
xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);
//connectionString = "data source=servername;initial catalog=databasename;user id=username;password=password;";
SqlConnection cnn = new SqlConnection(GetConnectionString());
cnn.Open();
sql = "SELECT Story, CreationDate FROM Story";
SqlDataAdapter dscmd = new SqlDataAdapter(sql, cnn);
DataSet ds = new DataSet();
dscmd.Fill(ds);
for (i = 0; i <= ds.Tables[0].Rows.Count - 1; i++)
{
for (j = 0; j <= ds.Tables[0].Columns.Count - 1; j++)
{
data = ds.Tables[0].Rows[i].ItemArray[j].ToString();
xlWorkSheet.Cells[i + 1, j + 1] = data;
}
}
xlWorkBook.SaveAs(path+".xls", Excel.XlFileFormat.xlWorkbookNormal, misValue, misValue, misValue, misValue, Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);
xlWorkBook.Close(true, misValue, misValue);
xlApp.Quit();
releaseObject(xlWorkSheet);
releaseObject(xlWorkBook);
releaseObject(xlApp);
//MessageBox.Show("Excel file created , you can find the file c:\csharp.net-informations.xls");
}
private void releaseObject(object obj)
{
try
{
System.Runtime.InteropServices.Marshal.ReleaseComObject(obj);
obj = null;
}
catch (Exception ex)
{
obj = null;
//MessageBox.Show("Exception Occured while releasing object " + ex.ToString());
}
finally
{
GC.Collect();
}

If the gridview binds to empty dataset, I need to still show a gridview so that users can ADD more using the textfields in the bottom of the footer template. Since the gridview is empty it won't bind not allowing rendering of the <footer template> I guess I should create a empty dataset if the gridview is empty. How do I check for this and can this be done in GridviewRowEventArgs

Actually I have a SQL query that a user exports to excel in our web server. I did it in c# with Visual Studio 2003 (.Net v1.1): I get the data from a SQL server into a Dataset, then with this method I create the XLS file:
private void ExportAsExcelFile ( DataSet dtExport )
{
Response.Clear() ;
Response.ContentType = "application/vnd.ms-excel";
Response.ContentEncoding = System.Text.Encoding.UTF8 ;
Response.Charset = string.Empty ;
Response.AddHeader ( "Content-Disposition", "attachment;filename=data.xls" ) ;
System.IO.StringWriter objStringWriter = new StringWriter () ;
System.Web.UI.HtmlTextWriter objHtmlTextWriter = new System.Web.UI.HtmlTextWriter(objStringWriter) ;
DataGrid objDatagrid = new DataGrid () ;
objDatagrid.DataSource = dtExport ;
objDatagrid.DataBind () ;
objDatagrid.RenderControl ( objHtmlTextWriter ) ;
Response.Write (objStringWriter.ToString()) ;
Response.End () ;
}
Well, this works when the SQL query has 10.000 rows and so on. But now the query has more than 200.000 rows, and I´m getting a TimeOut Error trying to export the data. I read about generate this big files with a Store Procedure and the SQL Commad: BCP [URL], but I tryed and it fails. I have no permissions to execute this command. Is there any other way to export this SQL data to Excel via a ASPX page?

I need to give users of my asp.net/vb.net web application the ability to click a button which will then send them an e-mail with the contents of a SQL query attached as an Excel e-mail attachment.
I can manage all of this apart from getting the contents of a VB dataset object into an Excel file on my server.
I know how to export a gridview to Excel at the client end, but my boss has been adamant that he wants the button to send an e-mail with the results attached - I have no need to display a gridview at all.
How to export the contents of a datareader or dataset directly into an Excel file at the server side?

I've got a data table with columns in which include Item, Category and Value (and others, but those are the only relevant ones for this problem) that I access via LINQ in a C# ASP.Net MVC app. I want to transform these into a matrix and output that as a CSV file to pull into Excel as matrix with the items down the side, the categories across the top and the values in the row cells. However, I don't know how many, or what, categories there will be in this table, nor will there always be a record for each item/category combination.
I've written this by looping round, getting my "master category" list, then looking again for each item, filling in either blank or Value, depending on whether the item/category record exists, but as there are currently 27000 records in the table, this isn't as fast as I'd like. Is there a slicker and faster way I can do this, maybe via LINQ (firing into a quicker SQL statement so the DB server can do the leg-work), or will any method essentially come back to what I am doing?

I have a GridView that I want to export to Excel. When I use the sample code I find online, it exports the content to Excel just fine, but for some reason it also clears out all grid lines outside of my exported table.
For your average excel user this is easy enough to fix, but I need this solution to work for everyone.
So then is there a way to export the data in a GridView into an Excel Workbook so that it looks like it was just typed into Excel? I've pasted the code I am using below, assume that a GridView called toPrint exists and has accurate data.
Response.Clear();
Response.AddHeader("content-disposition", "attachment; filename=" + name + "_Registration_Forms.xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
Page.EnableViewState = false;
System.IO.StringWriter stringWrite = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
toPrint.RenderControl(htmlWrite);
Response.Write(stringWrite.ToString());
Response.End();
EDIT: Found one partial solution. If I export as a comma-delimited list and set the header to be a CSV file, it opens fine and all grid lines (even those outside of the exported data) are showing. The only problem with this of course is having to strip out every comma and newline character from my values before exporting them.
