Easy but worth publishing.. Uploading document to Doc Library via Code..

 public static void PushFileToDocLib()
        {
            SPSecurity.RunWithElevatedPrivileges(delegate()
            {
                using (SPSite site = new SPSite("site url"))
                {
                    using (SPWeb web = site.OpenWeb())
                    {
                       
                        string fileToUpload = "c:\\ExcelWorkBookName.xlsx";
                        if (!System.IO.File.Exists(fileToUpload))
                            throw new FileNotFoundException("File Not Found", fileToUpload);
                        SPFolder docLibrary = web.Folders["Document Lib Name"];
                        Boolean ExistingFiles = true;
                        string fileName = System.IO.Path.GetFileName(fileToUpload);
                        FileStream fileStream = File.OpenRead(fileToUpload);
                        SPFile spFile = docLibrary.Files.Add(fileName, fileStream, ExistingFiles);
                        docLibrary.Update();



                    }
                }
            });
        }

Enable/Disable Asp validators via Javascript..

Yes.. it is among the most fundamental functions of javascript but I admit that i didnt know about it. So i tend to share to those who sometime somewhere stands on my feet.

Ok, there is a function call ValidatorEnable(control, bool status).

This function enables/disables the validator control specified as parameter in the fucntion.

For Eg:
function ActivateValidator(Ctrl) {

      alert(Ctrl.value.length);
      if (Ctrl.value.length > 0) {
            var myValidator = document.getElementById('<%=rfvLowTier.ClientID %>');
            ValidatorEnable(myValidator, true);
}     Hope this helps!
