- Databinding a Multi Column List?I need to databind a record set from the database into a page.
The output I need is a textbox and a label for every item in the
resultset, but I don't want a long vertical list... instead I want a
table with 3 or 4 columns, with each cell holding a textbox and a
label.
So if I were to bind this to a datagrid, the default view would be a
tall and narrow grid, but what I want is more of a rectangular shape on
the form.
Anyone know if this type of thing is possible?

- Weblog applicationHi,
which blogging engine would you recommend? Of course, I could settle for a mature application like Movable Type, but I would prefer a system written entirely in C#/ASP.NET - if possible with complete source code in order to adapt it to my requirements.
Are there any ASP.NET blogging engines that have reached an advanced stage? Would .Text or dasBlog be a good choice?
And: When will the Weblog Starter Kit see the light? ;-)
Many thanks,
P.

- Dynamically added LinkButton event handlingHi,
I have a strange issue occurring with LinkButtons that are dynamically added
to each (data) row of my DataGrid on that grid's ItemDataBound event. Each
LinkButton is assigned its own event handler to deal with the Command event,
but for some reason I can get this to work in a C# project but not in a newly
created VB.NET one.
The relevant VB.NET is as follows:
''' <summary>
''' Bind the columns within the grid to runtime data
''' </summary>
''' <param name="sender"></param>
''' <param name="e"></param>
Protected Sub MattersGrid_ItemDataBound(ByVal sender As Object,
ByVal e As DataGridItemEventArgs)
If (e.Item.ItemType = ListItemType.Item OrElse e.Item.ItemType =
ListItemType.AlternatingItem OrElse e.Item.ItemType =
ListItemType.SelectedItem) Then
Dim l_link As New LinkButton
With l_link
.ID = "MatterSelectedButton"
.Text = DataBinder.Eval(e.Item.DataItem,
"Name").ToString()
If e.Item.ItemType = ListItemType.SelectedItem Then
.BackColor = System.Drawing.Color.LightYellow
Else
.CommandName = "ItemSelected"
.CommandArgument = e.Item.ItemIndex
AddHandler .Command, AddressOf MattersGrid_Command
End If
End With
' the 1th column is the templatecolumn in the grid
e.Item.Cells(2).Controls.Add(l_link)
End If
End Sub
''' <summary>
''' Handle click-commands performed on the grid (TODO; currently
misbehaving)
''' </summary>
''' <param name="sender"></param>
''' <param name="e"></param>
Protected Sub MattersGrid_Command(ByVal sender As Object, ByVal e As
CommandEventArgs)
If (e.CommandName = "ItemSelected") Then
MattersGrid.SelectedIndex =
Integer.Parse(e.CommandArgument.ToString)
RebindDG()
End If
End Sub
and the similar, but working code in C# is:
/// <summary>
/// Bind the columns within the grid to runtime data
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
protected void TestDataGrid_ItemDataBound(object sender,
DataGridItemEventArgs e)
{
if (pr_debug) this.Page.Trace.Warn("TestDataGrid_ItemDataBound");
// only display the link on standard grid items (not
edit/select/header etc.)
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType ==
ListItemType.AlternatingItem)
{
LinkButton l_link = new LinkButton();
l_link.Text = DataBinder.Eval(e.Item.DataItem,
"ID").ToString();
l_link.CommandName = "ItemSelected";
l_link.CommandArgument = e.Item.ItemIndex.ToString();
l_link.Command += new
CommandEventHandler(TestDataGrid_Command);
// the 1th column is the templatecolumn in the grid
e.Item.Cells[1].Controls.Add(l_link);
}
}
/// <summary>
/// Handle click-commands performed on the grid
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
protected void TestDataGrid_Command(Object sender, CommandEventArgs e)
{
if (pr_debug) this.Page.Trace.Warn("TestDataGrid_Command");
if (e.CommandName == "ItemSelected")
{
TestDataGrid.SelectedIndex =
int.Parse(e.CommandArgument.ToString());
RebindDG();
}
}
I know there are a couple of subtle differences between the two, but the
core is essentially the same. However, the VB.NET one never fires the Command
event but the C# one does.
The DataGrid in both cases is also dynamically added to the parent control
(a Web Part) and is a 'global' protected object.
Any ideas?
Thanks,
Marc

- Transmit File AND HTML in ResponseThe standard method to transmit a file from an aspx page to a browser
is to stream the file to the response then end the response. The HTML
code generated by the aspx page is discarded, and the browser displays
or offers to save the binary file instead.
I would like to have the browser accept and display the revised HTML
code as well as offering to open or save the attached file. This
SHOULD be possible using a multipart MIME format - one part is declared
with a Content-Disposition of inline and a Content-Type of text/html,
and a second part with a Content-Disposition of attachment and a
Content-Type of application/octet-stream.
However, I haven't been able to get a valid multipart response out of
my aspx page (using multipart/mixed or multipart/x-mixed-replace). The
Page wrapper seems to be hard-coded to creating and sending headers
that are incompatible with this approach.
Has anyone succesfully done something like this? My example code is
below, which is a simple page that displays a file and updates a view
count. When the page is refreshed, the view count increments. When a
file is displayed, the view count is incremented in code but the
revised HTML is not sent to the browser, so you don't see the textbox
change. Also, since the ViewState is not updated in the browser, the
view count goes back to it's previous state when you next refresh.
I've tried removing the Response.End() at the end of the ShowDocument
method, but bad things happen (the next button click generates a
bizarre page that has the html code displayed twice with a partial HTTP
header between them...). I also tried manually setting the
Response.ContentType to multipart/mixed and writing the boundary
between the HTML output and the file streaming, but I couldn't change
the ContentType after the inital headers had been sent.
Thanks for any ideas...

- UnicodeEncoding / Encryption RSAHi,
I am trying to display the encrypted value on the console. When I use
the following
UnicodeEncoding encoding = new UnicodeEncoding( );
string constructedString = encoding.GetString(encryptedData);
And I print constructedString on to the console, I see "??????" When I
do a debug, I see boxes. But if I put a watch on the variable (on the
encrypteddata), see the hex values.
What I want to do is display the hex value on the screen.
Any help would be greatly appreciated.
Thanks,

dotnet-framework-aspnet, Cacheing Business Objects
Hi, I have some business objects that are pretty simple. They get
instantiated and have a few properties, methods, and events. The business
objects talk to the database directly or access web services. But 99% of
the time when they are instantiated or initially used, they access a
database and receive a datatable.
Can someone show me how to do the following;
1) cache the business object in a way that it gets used by all of the users
to the web site. I would like to store it so that each subsequental user
does not cause the database to run the query again and I do not use up the
web server memory. Maybe after 5 minutes it can be emptyied from the cache?
2) cache the business object on a per user basis, so that once the users
session starts the object gets created and doesn't have to go back to the
server to run the query again. Unless maybe their session expires.
Does this make sense? You can talk back to me using a foo{} fake class
object. I will understand. I use 1.1 but will use 2.0 and maybe 3.0 next
year.

- Page is nullI'm converting a custom webcontrol from ASP.NET 1.1 to 2.0 to take advantage
of 2.0's new features, particularly using the WebResource handler to embed
Javascript includes and GIFs within the assembly instead of placing such
files in an aspnet_client sub-directory. The only problem I've found with the
conversion is that when I call :
this.Page.ClientScript.GetWebResourceUrl()
as a result of calling EnsureChildControls() in property get and set
methods, this.Page is null; I guess this is because the control hasn't been
inserted in the Page's controls collection.
Is there some way to force the control to add itself to the page so that I
can avoid this error?
I guess I could move the calls to this.Page.ClientScript.GetWebResourceUrl()
to the control's prerender method but I'd rather void this if possible.
Are there any good web resources on the differences/enhancements for
creating ASP.NET 2.0 custom web controls? I've looked at Nikhil Kothari's
blog. Any others worth checking out?
Any info/advice gratefully appreciated.

- Validate multiple PanelsI have a form that i've split up into multiple asp:panels, each panel
has a number of validators which work correctly.
At on the last panel, i want to commit the data collected to a
database. I figured since all the panel data is still being sent
through the postbacks, instead of using Sessions, or HttpContext, I
could just take the values from the textboxes.
This all works fine, except for security. I realized that I could
inject new values into the POST data. Once a page has been validated,
its not validated again before committing to the database, in essence,
making the validators on the other panels useless.
To fix this, before committing, I would get a list of all the
validators on the page, re-validate each, and if all of them were
still valid, commit. That way any injected POST variables would
become invalid and the commit would not happen. Code:
foreach (IValidator validator in Page.Validators)
{
validator.Validate();
if (!validator.IsValid)
return;
}
This gets a list of all the validators across all the panels, but
Validate() does not update the IsValid property and the injected
variables are allowed through. ... How come Validate() is not
updating? Testing, if I set a textbox.text = "" after it initally
validates, the textboxes custom validator which checks for length > 5
validates to true, even though it is not.
Any help would be greatly appreciated!

- Web service request does not reach IISI'm writing a Windows Forms application which gets data through a Web
Service. I'm trying to use the IIS HTTP 1.1 native compression. In
order to do that I've added the following methods to the proxy class
generated by Visual Studio:
protected override WebRequest GetWebRequest(Uri uri)
{
WebRequest request = base.GetWebRequest(uri);
request.Headers.Add("Accept-Encoding", "gzip, deflate");
return request;
}
protected override WebResponse GetWebResponse(WebRequest request)
{
HttpWebResponseDecompressed response = new
HttpWebResponseDecompressed(request);
return response;
}
The HttpWebResponseDecompressed class receives the compressed response
and decompress it. This is what is happening: if I remove the second
line from the GetWebRequest method (which adds the header), all the 9
requisitions that I make on the program's initialization have answer.
But when the header is added, only the first 4 requisitions receive
answer (the answer is correctly compressed).
I've enabled the ASP.NET trace (which generates the trace.axd page) so
that I could see the requests received by IIS and the last 5 do not
appear. If I put a breakpoint in the GetWebRequest method, the
breakpoint is hit but they do not reach IIS.
Can anyone tell me what is happening or what can I do?
Thanks

- Using Session from a Windows App through a WebServiceI found the solution.
What I did wrong was to create a new CookieContainer for each call to
the webservice.
Instead I have create a private variable to hold the CookieContainer
and then only set this variable if its value is null.
i.e.:
private CookieContainer thisCookie;
private void button1_Click(object sender, System.EventArgs e)
{
StatusWS.GetStatus objWS = new StatusWS.GetStatus();
if ( thisCookie == null )
{
thisCookie = new CookieContainer();
}
objWS.CookieContainer = thisCookie;
textBox1.Text = objWS.GetStatusSession( "", "" );

- Custom Control - Collection PropertyHey gang. I am taking the task of trying to learn how to write custom web
controls.
I have started with inheriting from the VS 2005 default which is UserControl.
I am implementing collection and just basic properties in my control and
they are compiling and running so far but when I try and view the page in the
designer I get such things like:
Error Creating Control
Type 'System.Web.UI.UserControl' does not have a public property named Columns
But when I run the page everything is okay. Could someone please describe to
me why this is occuring?
Also most examples I see using Collections uses Control or WebControl. Is
there any disadvantage to using UserControl and does this cripple my use of
properties in any way? I like the design-time support for the UserControl.
Any help would be greatly appreciated.
Thanks and take care.

// in page load, (!IsPostBack), Page.SmartNavigation is initially set on.
protected void btnNext1_Clicked(o,e)
{
Page.SmartNavigation = false; // does not take effect on this round trip!
pnlStep1.Visible = false;
pnlStep2.Visible = true;
}
protected void btnNext2_Clicked(o,e)
{
pnlStep2.Visible = false;
pnlStep3.Visible = true;
}
// Only on a subsequent round trip, for example to display pnlStep3, does
SmartNavigation go off.
So what is the deal with SmartNavigation? Is it one of those things that is
determined on InitComponent, before subsequent events fire, or is it
something we are supposed to be able to control?
Any help would be appreciated.

- HeaderStyle - How to align differently then rest of girdI am creating a datagrid. I need for the header to align closer to the
bottom of the grid row then then the rest of the data in the grid. I have
tried using HeaderStyle and putting a style of padding-bottom, setting it to
a negative number, but that doesn't seem to have an affect on the look. The
padding for the grid itself is 4px, but I need the header to have NO padding.
Any ideas?
Here is the code (keep in mind it is using style sheets where I am changing
the padding-bottom to no avail!):
<asp:DataGrid Width="100%" id="companyGrid" runat="server"
AutoGenerateColumns="False" CssClass="reporttype highlight" GridLines="None"
style="MARGIN-BOTTOM: 0px">
<AlternatingItemStyle CssClass="greyBkg"></AlternatingItemStyle>
<HeaderStyle CssClass="reporttypeheader"></HeaderStyle>
<Columns>
<cc:RowSelectorColumn HeaderText="COMPANY NAME" SelectionMode="Single">
<ItemStyle Width="40px" CssClass="leftcolumn"></ItemStyle>
</cc:RowSelectorColumn>
<asp:BoundColumn DataField="CompanyName"></asp:BoundColumn>
<asp:BoundColumn Visible="False" DataField="CompanyGUID"></asp:BoundColumn>
</Columns>
</asp:DataGrid>
