I have a DataGrid which contains 1 visible column which is a LinkButton:
<Columns>
<asp:BoundColum n DataField="Prod uctId"
Visible="False" ></asp:BoundColumn >
<asp:BoundColum n DataField="Down loadURL"
Visible="False" ></asp:BoundColumn >
<asp:TemplateCo lumn>
<ItemTemplate >
<asp:LinkButt on ID="lnkArticle " Runat="server"
Text='<%#DataBi nder.Eval(Conta iner, "DataItem.Title ")%>'
CommandName="Se lect" />
</ItemTemplate>
</asp:TemplateCol umn>
</Columns>
The data source is a table of PDF files. It contains the Id, the path to the
file, and the title of the file. On the SelectCommand event of the DataGrid,
all I'm doing is streaming the PDF file to the browser:
protected void dgReader_OnSele ctedIndexChange d(object sender,
System.EventArg s e){
Response.ClearC ontent();
Response.ClearH eaders();
Response.Conten tType = "applicatio n/pdf";
Response.WriteF ile(dgReader.Se lectedItem.Cell s[1].Text);
Response.Flush( );
Response.Close( );
}
When I click the select button, I'd like the streaming of the PDF to happen
in a new window.
One very important thing is that I can't pass a query string in the URL (to
prevent URL tampering). Of course, I could do this with a Guid if that's
what it came down to.
Thanks a million for your help 1 1469

You can't create a new window from the server. Only the client can do that.
Instead of the LinkButton, you could use a HyperLink, with Target="_blank" .
Use a GUID in the query string of the URL, and have the newly-requested page
translate that GUID into the PDF file which the second page would stream.

It seems that Ctrl-N in Mozilla opens a new empty browser window.
That's fine, I don't need to do anything about it.
But Ctrl-N in IE appears to clone the current window. Is there a way
to intercept the key so that I can do stuff on the server side to make
the new window behave correctly?

How do you get the height of the client browser in IE? Both
document.body.clientHeight and document.body.offsetHeight return the
height of the document. If the page is long and there's a vertical
scrollbar, you get the height of the entire document, screwing up any
chance of centering a window in the browser using these values.
Is there a way to get the height of the actual browser window and not
the entire page height?
Thanks.

Linking to a Targeted Browser Window
I'd like to open reference links to other web sites in a
separate browser window from the browser window hosting my
own web site pages. The Link Target reserve word "_blank"
opens a blank new browser window for every link, which can
sometimes result in a lot of open browser windows.
Is there no way to "reuse" a previously linked browser
window and have it load the new web page in Foreground

Hi, I have an issue with the OnSelectedIndexChanged event not firing for a
DropDownList control which is in the ItemTemplate of a DataList.
I have made an exact copy of the DropDownList control, and placed it outside
of the DataList and it fires the event just fine. So it's definitely to do
with it being in a template.
I've managed to reproduce the issue on a small test app, the code and html
is below:

Hi folks,
I am trying to determine which item in a DropDownList Web control has been

I have posted an OnSelectedIndexChanged subroutine in my code with a

I have a strange problem. It seems that for some reason, a
OnSelectedIndexChanged event is no producing an error in IE6. What concerns
me is that I just performed that large Windows update a couple of weeks ago
and it updated ActiveX "stuff" in IE. I'm not sure if the update has
effected IE or there's something wrong with mt .net application.
I have a simple DDL. It calls a sub when the value in the DDL is changed.

I have a simple and common scenario. I'm developing pages in VWD and FTP-ing
them over to a test servr running Window 2003, NET2 Framework. On my page,
I have a DDL that causes a postback and executes a sub when the value has
changed. For some reason, it just quit working. I get a js error in IE6
(but NOT in FF 1.5) and gives me a vague error about:
'event' is null or not an object.Line X, character X.
