Hi, All,
I'm having problems getting OnInit to fire in my
UserControl, when I use a custom template to render the
control. The control will render to the browser and it
wasn't until I needed to perform some initialization in
the OnInit event did I realize that this event was never
firing.
Two Question:
1. Why Isn't OnInit firing in the UserControl class
2. Why am I getting a NullReferenceEx ception when I
try to assccess mMenubar after I Load the UserControl
in the Somepage class? The way I understand it is
this should Get initialized before OnInit is fired in
the UserControl Class. Obviously this isn't so!
*************** *************** *************** *************
//Template class
Public Class myTemplate : Page
{
Control vMenubar;
Public Control VMenubar
{
get{Return vMenubar;}
Set{vMenubar = value;}
}
protected override void Render(HtmlText Writer write)
{ 1 2244

Hi,
Another question from a C# newbie:
I have a usercontrol class that includes a customized control.
Now, if I create an instance of the class, and click on it, a click
event is raised for the customized control within the class. This is
good.
What I also want is to raise a click event for the class itself.
For instance,

Hi all,
I don't normally post swathes of code like this but I am truly banging
my head off my desk here...
I've dynamically created a datagrid within a usercontrol. There are two
columns which contain buttons to Edit & Delete rows. For some reason,
the ItemCommand event which these should be connected to isn't firing.

Problem
I have an ASPX file, with a table of 3 columns, 2 rows with a usercontrol in
the middle column (in the code snippet stated below, although in reality,
the left hand column would also have a user control).
I have a "footer" on the second/bottom row. However, when the User Control
in the middle column, first row is generating a lot of text, the text is
"squashing" the text in the second role!

Hello,
I am generating a PDF and writing its bytes to the browser using
Response.BinaryWrite(). Before I do this I set the
response.contenttype = "application/pdf".
When I run in debug I see that the onInit event gets fired twice,
causing my PDF to be generated 2x, to be sure that the debugger is not
causing the problem, I write out a text file in the onInit and run it
compiled, 2 events are firing compiled also.

I have a custom control that is thrown onto a UserControl that is
thrown onto a WebForm. Basically, I've got a scenario where if my
UserControl sets an attribute on the custom control in the ascx,
EnsureChildControls gets called, creating the control before the
UserControl is even added to the webform. The problem with this is
that the UniqueID of the custom control will be false, since OnInit
has yet to be called on its parent, somehow...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
