Question

I have a page called test.aspx with test.cs.
However, i want to access my control called mbResult
Which is my custom messagebox control, from a sepearate CS page.
I know many people have asked this question and i have found that this is a method to access my controls.

MessageBoxControl mbox1 = this.FindControl("mbResult") as MessageBoxControl; 

But I keep getting this error
Error 5 Keyword ‘this’ is not valid in a static property, static method, or static field initializer

Any ideas on how to access this control all i am trying to do is make it visible.
Thanks

You need to move the code into a non-shared method. You need to be operating in an instance of the page.

Update for clarification in comments

Unfortunately, your application is going to need some restructuring.

If the messageboxcontrol is shown in a new window, then you will need to pass the value from your source page to the new window in the query string.

However, if you want the messagebox control to be displayed on the source page, then you will need to convert it from a page to a UserControl, add a reference to the user control to your source page, and then add an instance of the usercontrol directly to the source page.
