When using System.IO.FileStream, I write 8 bytes, then seek to the start of
the file, does the 8 bytes get flushed on seek and the buffer become a
readbuffer at that point instead of being a write buffer?

If HasFile is true, why is PostedFile "sometimes" == null in my tests?
That is, if I resubmit the form with the same data it's not null, and may be
repeatedly not null.  But then it will occasionally be null again, for one
or two submits.  It seems to be random.

After a button click, nothing gets posted back to the form.  The
Page_PreRender is firing ... I am tracing it through line by line.  But
lbl_ErrMsg3 never changes.  (I also tried it with a textbox and it doesn't
change the Text either.)

This may not be possible, but here goes:
I'm trying to save space on my asp.net page by using four list boxes in
the same table cell. What I'd like to do is have my user, via a button,
enlarge one list box so it covers the others. This is easy on a VB

I would like to support a custom tag inside my custom control like this:
<cc1:MyControl  id="x"  runat="server">
   <customTag prop1="x" prop2="e" />
   <customTag prop1="y" prop2="d" />

I have a form which creates a request for access to one or more departments.
The formview uses datasource1 to pull all of the files and create an insert

field with a list of available departments from ...

Can I create a user control so that when I drop it on the web form I can put
text between the start and end tags as listed
<uc1:KeyFeatures id="KeyFeatures1" runat="server" >test..</uc1:KeyFeatures
Each one will have some lengthy text with bulleted lists, etc and I wanted

This doesn't seem to work.  It throws an InvalidCastException.
In general, when I'm trying to enumerate something, how do I find what type
of object the enumerator returns?  Help doesn't seem to be much help in this
regard.

I am fairly new to ASP.NET and have been using the data access tutorials at
www.asp.net to get an understanding of some of the basic data access
concepts. I have created a page that uses a detailsview to insert records
into a table and a gridview to edit and delete existing ...

Please re-direct me if I'm not in the most appropriate NG.
The company I work for has an Intranet. One of the pages (.aspx)

When one of their selections is amended, the whole screen refreshes.

I have a radio-button list with 2 buttons. The property for this control are

From an ASP.Net page which is using a SSRS 2005 that is using SQL
authentication which works correctly when designed. However when
called from the web page as a .Net component shows the following error

I've got a web page that holds a user control, which is really a
factory that might load up one of several different user controls
inside it. The web page doesn't really know what kind of control is
getting loaded, and it doesn't care. It just passes the data in to the

Is it true that one of the benefits of using an UpdatePanel is that the
screen will maintain it's position across partial postbacks?  If so, I must
be doing something wrong.  When a repeater control (which is contained in an
UpdatePanel) is refreshed, the page is jumping to the ...
