hello,
i have a user control that works great, when its used as a design-time
controls. however, when i try to use it as a programmtic control, im
running into troubles.
the control is pretty simple: it has a textbox, and a grid. in my
webform, on button_click i call one of its methods to do stuff (like
bind data and set a value to the textbox), and it works great.
but, when i try to do this from a new programmatic instance of the
control, it breaks anytime i try binding data/text to its child
controls. ala:
webform.aspx.cs
private void btnSubmit_Click (object sender, System.EventArg s e)
{
My.Controls.Res ultsPane results = new My.Controls.Res ultsPane();
results.SetIt() ;
}
resultsPane.asc x
<span class="lb01">Ti tle: </span>
<asp:TextBox ID="tbTitle" Runat="server"/>
resultsPane.asc x.cs
protected TextBox tbTitle;
public void SetIt()
{
//breaks -- Object reference not set to an instance of an object.
tbTitle.Text = "xxx";
}
....any idea whats up?? ive noticed that quickwatching the tbPackage
yields "<undefined value>", whereas i was expecting properties related
to the textbox.
thanks!

ah, ive been working w/ server controls too long... the syntax for user
control loading is different:
My.Controls.Res ultsPane results =
(My.Controls.Re sultsPane)LoadC ontrol("~/controls/resultsPane.asc x");
....then you can do stuff w/ it, add it to the page, etc.

Hi,
I have a strange problem with a usercontrol on a page. The usercontrol
dispalyes three categories (From a database) when the user clicks a category
they see all the products in a shop for that category, the results are paged
10 to a page and the user can page them.
As this "Category" usercontrol hardly ever changes I wanted to setup up
caching for it. However I realised that when the user clicks a ctageory it
is selected and...

for the length of this posting, but I wanted to make sure that I get an

I can set the properties of the Panel within the UserControl via the

Hello All:
Do I have to use the LoadControl method of the Page to load a UserControl?
I have a class which contains three methods (one public and two private).
The class acts as a control server. It "serves" back the required control
(either WebControl or UserControl) based on the contents of an xml file. The
code in the webform places each control in a TableCell.
My problem is that the control server works as far as returning the...

Hi,
I have a user control that in turn creates a bunch of webcontrols
dynamically and handles the events these webcontrols raise. It used to work
fine on ASP .Net 1.1 but when compiled on 2.0 it does not. The problem is
that the webcontrols get created on the OnLoad event of the usercontrol and
the event handlers are assigned at the same time. I have to click twice on
the controls for the events to be raised, the first time nothing...

I have a very unusual request.
I need to be able to generate reports and save them as TIF
files, with full programmatic control. The application will
provide the filenames. Each page of the report will be saved
as a seperate file. All the user should have to do is press a
button to generate the TIFs, without having to "touch the meat"
of viewing the report, choosing a file path/name, answering
prompts, etc.

hello,
ive got a usercontrol that has some textboxes, a button, and a handler

clicked its event handler loads up the routine and i do db stuff.
however, i am now adding the control to the page programmatically (on a

My goal was to create my own DataSource and DataMember properties that

thus all other controls on the parent form. (I want various controls

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.
