Answer 1

Try with the following code,

Page.ClientScript.RegistrerClientScriptBlock(this.getType(), "script", "SP.UI.ModalDialog.commonModalDialogClose(1, someValue");

Or use a script manager in your page and try with the following code,

ScriptManager.RegisterClientScriptBlock(Page, Page.GetType(), Guid.NewGuid().ToString(), "
<script type="text/javascript" language="javascript">                SP.UI.ModalDialog.commonModalDialogClose(1, 'Submitted');     </script>", true);

Answer 2

Try this

this.Response.Write("<script language=\"javascript\">window.parent.close();</script>");
this.Response.Flush();

It always works for me.

Answer 3

The reason why your redirect code isn't working and it raises Null Exception may be because your WebPart is a Sandboxed solution.

For redirect in SandBoxed solutions you can try the following:

1. Create a Literal control.

2. In your code-behind, add similar code as this one:

   literalRedirect.Text = "<script type='text/javascript'>window.location.replace('" + redirectUrl + "');</script>"; //where /(redirectUrl) is a String variable.
