Solution 1

Are you surprised by the StackOverflowException? Your property accessor calls the property accessor, which calls the property accessor, which calls the ....

Your property accessor needs to return the control, not the property. If the property name is the same as the control ID, then you'll need to change one. Remember, C# is case-sensitive, so you could simply change the case:

C#

public Button SeeProfole
{
    get { return seeProfole; }
    set { seeProfole = value; }
}

on following line it give error thar seeProfole does not exist which is my control name
return seeProfole

Richard Deeming 14-Apr-16 15:15pm

Well, if it's telling you that seeProfole doesn't exist, then it's either not the ID of your control, or the control is nested inside a data-bound control, and doesn't have a field in the code-behind.

i change codefile by codebehind and it is my control name

Richard Deeming 14-Apr-16 15:18pm

Well it's clearly NOT your control's ID; if it was, you wouldn't be getting that error!

Kishor-KW 14-Apr-16 15:20pm

but it is not in contextplaceholder. now i take it outside of it.

Richard Deeming 14-Apr-16 15:22pm

And?

Remember, I can't see your markup, so I can't tell you why the control doesn't exist in the code-behind.

I am doing this on masterpage.cs file. I do not have masterpage.designer.cs file
is that the issue?

Richard Deeming 14-Apr-16 16:00pm

That depends on the project type - is it a Web Site project, or a Web Application project?

Kishor-KW 14-Apr-16 16:02pm

web application

Richard Deeming 14-Apr-16 16:06pm

So according to this[^], you need to right-click on the root folder in Solution Explorer, and select "Convert to Web Application". That should then add the missing designer files.

Button seepro = (Button)Master.FindControl("seeProfole");

I did thid on the page where i use masterpage. but still i have a question that is that the case materpage control are not access on it's own code behind page ? because same give null result at masterpage.cs file
plz clear this doubt

Richard Deeming 14-Apr-16 16:12pm

Again, I can't see your markup, so I can't tell you why the control isn't available from the code-behind.

Very, very bad. It has nothing to do with your problem, which is perfectly explained in Solution 1. If you won't follow it, nothing will work.
