Export To Excel

Is there a way to export data from a control into excel if the control
is not server side? Do I have to do it with java script or can I do
it inside my VB.NET code?

Difficult to say without knowing what control it is... You say it's not a
server-side control, so is it an ActiveX control or a Java applet...?

Do I have to do it with java script or can I do it inside my VB.NET code?

See above.

server-side control, so is it an ActiveX control or a Java applet...?

It's a control built inside the HTML of the page but it does not have
the runat="server" tag in it. So I don't have a way to access it in
VB.NET.

I'm relatively new to ASP.NET (some training) so am not real sure the
best approach at grabbing this control and it's data.

Here is a sample of what the first part of the control's code looks
like in the HTML. I don't have any way that I can see to grab this
"DataTable" control (and it's data) inside VB.NET:

<table id="DataTable" dataSrc="#Repor tResult" cellSpacing="0"
cellPadding="1" border="1">
<THEAD>
<TR>
<td class="COLHDR2" onclick="SortFi elds('@SomeDBPa rameter')"
width="65">Some DBValue</td>
<td class="COLHDR2" width="70"
onclick="SortFi elds('@AnotherD BParameter')">A notherDBValue</td>

It's a control built inside the HTML of the page but it does not have
the runat="server" tag in it.

So what is it, then...???? Where does it come from? What builds it? Where
does it get its data from...?

<table id="DataTable" dataSrc="#Repor tResult" cellSpacing="0"
cellPadding="1" border="1">
<THEAD>
<TR>
<td class="COLHDR2" onclick="SortFi elds('@SomeDBPa rameter')"
width="65">Some DBValue</td>
<td class="COLHDR2" width="70"
onclick="SortFi elds('@AnotherD BParameter')">A notherDBValue</td>

Wow! It's been a while since I've seen anything like that! Is this even
ASP.NET...?
http://msdn.microsoft.com/library/de...es/datasrc.asp

OK, so what is populating the table's dataSrc property...?

You'll have to bear with me. I'm new to ASP.NET and new to this app.

So what is it, then...????

It is a control that is built inside HTML. I'm not sure what else to
say to answer that question.

Where does it come from?

The control? It comes from the HTML side of this page (am I still not
getting the question)?

What builds it?

Again, isn't the HTML inside the page building this control?

Where does it get its data from...?

The data is grabbed from the database and dumped into a dataset. Then
the xml from that dataset is put into a HtmlGenericCont rol object.
However, once I have left the method that does this and do anything
else, that HtmlGenericCont rol object is empty. So I can't figure out
how to get my hands on the data.

Is this even ASP.NET

Yep

OK, so what is populating the table's dataSrc property...?

Same answer as the data question above (I believe anyways)

Aha - now we're getting somewhere! OK, so you do have access to the
underlying data... So how precisely do you want to export it to Excel...?
You have a few possibilities here... Do you want to display the data in
Excel in a browser window, create a CSV file which the user can download and
display in Excel etc.

What is the purpose of exporting the data to Excel anyway...? Is the user
going to process it in some way...?

I'd like to create it in a csv file.

the user would like to save the data off and process it at a later
time.

So now that we know what I want to do, does anyone know how I can do
it? How do I get ahold of a control that is built in HTML and not set
as server side and do so inside the VB.NET code?

Apologies - I thought you'd got it...

You don't need to "get ahold" of this control at all, as you already have
the data anyway (i.e. the dataset).

All you need to do is add another button to your page which takes the
dataset and does the export. There are tons of examples of the various ways
you can do this:

Hi Mark, I was kind of figuring that would be an option of mine, to
use the dataset originally returned and can do that easily enough.
However, woudln't there be a performance hit of some kind if I'm
storing the data in a control on the page, and I'm storing the same
data in a dataset in memory? By the way, thank you for your continued
help here. :)
