There are much better tutorials for this on the web than we could come up with in a short time here.
Hm... we had a reference to one of them here recently. Hold on, I'll have a look...
dear killer,
Thanks for u r reply.... your link has helped me alot.
now i am able to create user controls, set some properties. but still i have a problem.
my user control is an image. now i would like to assign a propery to my control called "mycolor". my objective is when ever user assigns this property with a different color, then my user control's color should be changed. how it is possible? my idea is instead of making color to my control, why don't i replace the image with another image which has the required color. if it is fine how to replace that. kindly help me if u know it.
Thanku
raghunadhs

I've been playing with some usercontrols myself, lately. I wouldn't claim to be expert, but can probably help a little.
The way I understand it, you need to... - Create a private variable to hold the property value. For example...
Private m_MyColor As Long (or possibly As OLE_COLOR) - Optionally, create a constant to hold a default value. For example...
Private Const m_def_MyColor As Long = &H00FF00 ' (Green) - Add routines to retrieve and set the property...
Public Property Get MyColor() As OLE_COLOR
MyColor = m_MyColor
End Property
Public Property Let MyColor(ByVal New_Value As OLE_COLOR)
m_MyColor = New_Value
PropertyChanged "MyColor" ' Note that property needs to be saved.
' I guess this might be where you need to do whatever
' it is you do with your color. Perhaps set UserControl.Bac kColor.
End Property - In the UserControl_Rea dProperties routine, add your one...
m_MyColor = PropBag.ReadPro perty("MyColor" , m_def_MyColor) - In the UserControl_Wri teProperties routine, add your one...
Call PropBag.WritePr operty("MyColor ", m_MyColor, m_def_MyColor)
Have a play with that, let us know how it goes. It may take some fiddling to get it right (I know it does for me.)

Hello,
I create a Table1 dynamically at run time, and at the same time, I would
like to create LinkButton controls, also dynamically, and insert them into
each line in my Table1. I would then like that, when clicking the
LinkButton, the user can be navigated to another page, carrying a variable.
I would like to use server.transfer method instead of QueryString as I don't
want the carried variable to be visible for the user.

Hi,
I am writing a GUI application. It will have a number of user defined
controls( I plan to use/create a user defined control that will output alarm
states that the user can also select and will open a dialog to give more
detailed information) .
The number of controls on the main GUI will vary from client site to client
site. I would therefore like to populate the dialog with these controls
dynamically.

It sounds to me like ASP, not ASP.NET is handling the
request for WebForm1.aspx. This is most likely an IIS
config issue that may have been caused by order of
installation or reinstallation, or possibly even
something that happened in IIS before .NET was
installed.
Here is a way to prove or disprove my theory:

Hi everyone,
As subject suggests I'm wondering how is it possible to do so in ASP.NET.
The fact is that I'd like to "atomize" an entire series of custom user
controls (.ascx and .ascx.vb) to redistribuite them to friends but without
having to give away my source code. I'd like to have only one clear, solid
dll. Is it possible? Maybe even a similiar way.
Thanks to everyone for the attention.

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