Of course you can. .NET is largely language agnostic, which is just a fancy way of saying if you can do it in one .NET language, you can do it in another.

I have a web application to display sales data. My input, transaction_header table, is like this:
| ... | van_id | sale_date | ... | | ... | Van A | 2012-03-01 17:28:38.000 | ... | | ... | Van A | 2012-03-01 17:33:54.000 | ... | | ... | Van B | 2012-03-01 12:33:48.000 | ... | | ... | Van B | 2012-03-01 12:38:14.000 | ... |
I need to export the transaction data to excel and the excel would show as:
| Gross Sales | | DATE | Van A | Van B | Van C | ... | | 1-Mar | $3,359 | | | ... | | $49,934 | $20,657 | $41,481 | ... | | 2-Mar | $3,633 | | $4,263 | ... | | $73,394 | $38,134 | $41,083 | ... | | 3-Mar | | | $2,118 | ... | | $40,831 | $39,838 | $32,344 | ... | | 4-Mar | SUNDAY | | 5-Mar | $4,387 | | $3,842 | ... | | $84,814 | $39,242 | $41,116 | ... | | ... |
My problem is the number of van may change over time. For the transaction_header table, this does not post a problem as there is just one more row. Yet for the output, it is a problem. Thw columns of my table may increase over time. Now how do I approach this problem?
Appreciate any feedback. Thanks.

There are a ton of examples online of how to export data to Excel. Start here.[^]
There are only 10 types of people in the world, those who understand binary and those who don't.

Yes, there are tons of example out there.  My question, I think, is more specific. The number of columns may increase (or even decrease, although I doubt it will) over time. Now how can I handle this?

Quote: The number of columns may increase (or even decrease, although I doubt it will)
That is just fine. Most examples I have seen use a DataGrid and set AutoGenerateColumns = true. This means that it does not matter how many columns you have.
The code is have used before is here.[^] All you have to do is set the datasource of the datagrid.

Try This...it will work as per your requirement:
protected void cmdExport_Click(object sender, EventArgs e)
{
clsDataAcess oDataAccess = new clsDataAccess();
oDT = new DataTable();
oConst = new clsConstMaster();
string filename = string.Empty;
try
{
oDT = oDataAccess.GetCustomerWholeInformation(Parameter To function Here);
if (oDT.Rows.Count > 0)
{
filename = "CustomerInformationFromMaster.xls";
System.IO.StringWriter tw = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(tw);
DataGrid dg = new DataGrid();
dg.DataSource = oDT;
dg.DataBind();
dg.HeaderStyle.BackColor = System.Drawing.Color.LightGray;
dg.HeaderStyle.Font.Bold = true;
foreach (DataGridItem i in dg.Items)
{
foreach (TableCell tc in i.Cells)
{
tc.Attributes.Add("class", "text");
//tc.BackColor = System.Drawing.Color.Blue;
}
}
dg.RenderControl(hw);
string style = @" .text { mso-number-format:\@; } ";
Response.Write(style);
Response.ContentType = "application/vnd.ms-excel";
Response.AppendHeader("Content-Disposition", "attachment; filename=" + filename + "");
this.EnableViewState = false;
Response.Write(tw.ToString());
Response.End();
}
}
catch (Exception ex)
{
MessageBox(ex.Message.ToString());
}
}
public override void VerifyRenderingInServerForm(Control control)
{
}

Hi,
I have a repeater control, for which I have header template and item template. Both are in different divs. Both divs are creating rows and border properly. The problem now is the header is having gap and then its body.
Is there any way that we can have border for the whole repeater control? Any sort of link or code snippet would be greatly helpfull.
thanks in advance,
Thanks & Regards,

Can we create a message box inside the Label?... and the msgbox contains a link that will use to pop up another form.?.. this program is using a VB.Net...

What are you trying to do? Click on a Label and pop up a message box? Click on the link inside the message pop up another form? Wow.
|
|
|
|
|
haha.. yeah.. i'm just trying to create an event handler calendar using a VB.net.. i don't have any idea on how to put an event to each date of the month.

That message does not make much sense. A message box / alert is shown on top of the form / web page.
A non-modal message box could go behind the application confusing the user.

OK.. thanks Sir.. but how about making an event calendar then if the user will point it's cursor on the date within a month there will be a message that shows all of the events of that date. is this possible using a VB.NET application Sir?

Anything is possible since you control the code. I think you should start by learning the language better and viewing samples that other people have.

Not that I am aware of, you need to use a div tag or panel with an id assigned

Hi,
I got it solved by append and remove css, and remove all the elements with that css class in the jquery.
Thanks,

Well if that backfires on you later on down the road, you can use jquery to dump or delete everything inside the div tags, and then write new html back inside the tags, while retaining your div tag css, so the div tags retain the proper spacing and alignment.
it works great for movie or flash objects, and will destroy the movie and audio as well. Or you can destroy an entire list of products, and write new ones, etc
Good to hear you solved it.
