Custom Controls

DFB
I have created a custom control which contains an asp:dropdown inside it and
embedded my custom control in my web page.

I am accessing this dropdown via javascript.

The Problem: when this asp:dropdown control was embedded directly in my
webpage ... my javascript call to reference this dropdown worked (javascript
referenced call "document.all.i dCategories").

BUT NOW ... because I have embedded this asp:dropdown id=idCategories within
my user control, the compiler has prepended it with a prefix id of _ctl0_, so
my javascript references to it no longer work.

HOW do I switch off this prepended prefix of _ctl0_ ... I did it before many
years ago .. but can't remember.

:|

Thank you in advance, frustruated!

You can't switch off the prefix _ctl0_ in a control. But you can use the
client id like _ctl0_idCategor ies in javascript.

I've developed a custom control (it's basically a drop-down list and then a couple of textboxes to include meta-data for the selection) that I'm embedding into another custom control (the idea is to allow a dynamic number of control1 to appear in control2). Everything renders correctly, however I could never retrieve data on postback from my embedded controls. Upon closer inspection, all of the embedded controls output without any "name"...

Hello i have made a custom control. i have placed a panel on it. I want this panel to behave just like the normal panel. The problem i was having is that the panel on my custom control doesnt accept other controls. The control i drag drop on it becomes the child of my custom control's parent form and not the child of my custom control. Then i added this line "" before my custom control class (i dont know what this line does). Now

Previously I used to create user controls if I wanted to use a specific set of controls in multiple pages, however I want to deploy my control in other applications so I thought of creating custom controls. Only problem is that I'm used to designing my controls in a WYSIWYG (tm) way (i.e. using the designer and writing HTML tags). The only way I found to create custom controls was to create controls dynamically, set their properties and...

I am trying to create a custom container control that will only ever contain a specific type of control. At design time, when a control of a different type is added to the container I would like to wrap the control in the proper control type - which is also a container.

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Overview: 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,...
