these two controls (Dropdownlist and button) are visible to the user in the control.

Okay. But it is a single control right ? So I guess disabling it should disable both controls.

I tried this code:
public override bool Enabled
{
get
{return base.Enabled;}
set
{
btnClick.Enabled=value;
ddList.Enabled=value;
}
}
But from designer I cannot change Enabled property to false, it stays as True. However, I can set Enabled property to false in aspx page.

Because base.Enabled returns true and in set method you are not making this as disabled. How about the following code ?
public override bool Enabled
{
get
{
return btnClick.Enabled;
}
set
{
btnClick.Enabled=value;
ddList.Enabled=value;
}
} In get you can return any controls enabled value. Because in set method you are changing both control properties.

I tried this, but the Property "Enabled" is not displayed in PropertyDescriptor. I've tried the code you have provided.

In sitemap path XML file, you should specify the page URLs.

byte[] im = (byte[])insunit.GetLogo(id);
MemoryStream ms = new MemoryStream();
ms.Write(im, 0, im.Length);
Bitmap bm = new Bitmap(im);
bm.Save(Response.OutputStream, ImageFormat.Jpeg);
//Img_Logo.ImageUrl=;

{
byte[] s;
string sqlstatement = "SELECT UnitLogoPath FROM Units WHERE UnitId='" + Id + "'";
s = (byte[])dbtObj.GetColumnValue(sqlstatement, "UnitLogoPath");

Abay Dhakan , In order to make the image appear into the image control , it is mandatory to display it in a blank aspx page and afterwards give the imageurl , the address of that page(where u have to display the image).

Wow - this is so wrong. If he saves the file to disc, he can put an image control anywhere he likes. Not saving it to disc is his core question.

The only way to do this, is to write an HTTP handler for a custom extension, which loads your image and feeds the bytes back. Otherwise, the image needs to be a file on your hard drive, not just a byte stream.

I have two type User, customers and admins. there is two different table.with "Forms Authentication", I must declare (for example) :
<configuration>
<system.web>;
<authentication mode="Forms">
<forms>
name=".MyCookie"
loginUrl="/login/mylogin.aspx"
protection="All"
timeout="80"
path="/"/>
after login when I call this code : FormsAuthentication.RedirectFromLoginPage(UseName,false);
How can I detect Admin from Customer?
How Can I have two login page and how can I use "Forms Authentication" in this way. (my customers and Dmins have roles)

Your design is broken. You should have one table, of all people who can possibly log in. Then your site should support roles, and only show options to a logged in user who has permission to see them.
