does anyone know what i am doing wrong?
It's just happened to me. It happened when I renamed page and moved aspx file within project folders, but code inside left unrenamed.
Change code inside from:
public partial class foldername_unrenamedname : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
}
to current
public partial class newfoldername_renamedname : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
}
And also edit Inherits property in Page tag to:
Inherits="Newfoldername_renamedname"
You can resolve this error by following the below steps , the root cause of this error is the incorrect mapping between web application project and the virtual directory in your IIS.
To Resolve this error , follow the following steps:
1-Right click - you web application project and select Properties -> Web
2- in the server section choose Use IIS Web Server -> then click Create Virtual.
3- Clean your project and compile again.
done :)
This info is on following site.
Here is another article which proposed different solution and cause there is that object is not initialized before use.
Closed the aspx designer, cleaned the project and rebuild it, everything started working perfectly. (using Visual Studio 2015)
I had the same problem with all my pages. I changed the version of .NETFramework and it worked. The version of .NETFramework at the time when components were added was different from the current version.
I had the same problem and I tried all of the above but none of them worked for me.
What did work was the following: Go to Project->Properties click on Web and then change the Server (mine was defined as Local IIS) to External IIS and Save.
I didn't even have to restart VS and the controls re-appeared correctly.
Once you get your controls to appear properly, you can change your Web->Server settings back to what they were before.
