Why it's not showing? Can any one tell me?

my code is:

You've called your controller '$this->_controller = 'adminhtml_svccs';' but the filename seems to be controller/Adminhtml/IndexController.php while it should be controller/Adminhtml/SvccsController.php.

Magento – Custom Admin controller not displaying in magento

I don't like that method of providing your own frontName, I prefer to overload the existing admin router because it's neat and quick. Start by changing this in your config.xml:

<admin>
    <routers>
        <adminhtml>
            <args>
                <modules>
                    <ics_easylife before="Mage_Adminhtml">Ics_EasyLife_Adminhtml</ics_easylife>
                </modules>
            </args>
        </adminhtml>
    </routers>
</admin>

This will make magento check for controller classes that start with Ics_EasyLife_Adminhtml before checking it's own Mage_Adminhtml. Rename your controller to Ics_EasyLife_Adminhtml_EasylifeController and rename it's corresponding file to EasylifeController.php.

Now an URL of adminhtml/easylife will expand to http://ipaddress/ics/admin/easylife/index and call your indexAction method. When making a menu entry use that URL of adminhtml/easylife. Even if you don't have any layout or blocks in place yet at least a page will show. When writing a layout use the layout handle <adminhtml_easylife_index>.

Magento – how to redirect a page using magento button

Starting of with the buttons. There is no technical difference between the buttons. It's only a styling matter. If you use the Magento button (and it's best to do so) you'll get a nicely styled button. Beyond that, both buttons do the same. The submit the form they're attached to.

How ever, make sure the type of the button is submit and not button.

Second, the redirect. The redirect should be done in the controller and not in an onclick event of the button. The flow is roughly something like this.

user fills out form and clicks button > controller handles the post data and saves it > controller redirects to desired end page

Your controller would look something like this

class [Namespace]_[Module]_IndexController
{
   public function indexAction()
   {
      [...]
      // page that displays your form
      [...]
   }

   public function postoneAction()
   {
      [...]
      // code that handles the post data
      [...]

      // redirect back to the index page, or any other page of your controller
      $this->_redirect('*/*/index');
   }

   public function posttwoAction()
   {
      [...]
      // code that handles the post data differently
      [...]

      // redirect back to the index page, or any other page of your controller
      $this->_redirect('*/*/index');
   }
}

[EDIT] to have 2 different types of 'submit', take a look at this post on Stackoverflow on swapping the action of the form depending on the button.

Basically you remove the action from the form, add a name to the form (myform for example) and add it to theonclick` of the buttons. Something like this.

<button onclick="document.myform.action='practice/index/postone';document.myform.submit();"> .... </button>

<button onclick="document.myform.action='practice/index/posttwo';document.myform.submit();"> .... </button>
