I have created a custom feature for adding a button in the SharePoint 2010 ribbon. If I click that button, I can open a show model dialog box which I have loaded a aspx file that contains file upload control and buttons. This thing works well on my machine.
When I deploy the solution to another machine, I can see the custom ribbon button. If I click it, I can get the aspx file but I get a file not found error. I have added javascript for the button coding
(ClientScript.RegisterStartupScript(this.GetType(), "alert", "alert('Please');", true);
Can anyone guide me?
