I am using ckeditor . Edit the file on server and save the file on server. It is not working on server but it is well working on my localmachine.

Here is code of edit and save button.

protected void btnSaveNews_Click(object sender, EventArgs e)
    {

        string str = Ckeditor.Text;

        string str1 = Server.HtmlDecode(str);

        //lblText.Text = str2;


        FileStream fs = new FileStream(Server.MapPath("~/NewsTextFiles/News.html"), FileMode.Create , FileAccess.Write);
        StreamWriter wr = new StreamWriter(fs);
        wr.Write(str1);


        wr.Dispose();
        fs.Dispose();

        pnleditor.Visible = false;
        upleditor.Update();
        upleditor.Visible = false;

    }

Make sure the user your Application Pool is running as has write permissions on that file / folder.

This might be:

IIS_USR or Network Service (can also be others).
