this is my block file /app/code/local/Ilogix/Regionbased/Block/Adminhtml/Regionbased.php

class Ilogix_Regionbased_Block_Adminhtml_Regionbased extends Mage_Core_Block_Template
{
    public function __construct()
    {
        parent::__construct();
    }
}

this is my layout xml file

<?xml version="1.0" ?>
<layout>
        <regionbased_adminhtml_index_index>
        <reference name="content">
            <block type="core/template"  name="regions" template="regionbased/index.phtml"/>
        </reference>
    </regionbased_adminhtml_index_index>
</layout>

Here when I use block type="core/template" it perfectly renders my phtml file but when I try to use block type="regionbased/adminhtml_regionbased" it does not render the phtml file . not sure what am I doing wrong here . Please help!

Thanks

Try this:

layout xml file:

<?xml version="1.0" ?>
<layout>
    <regionbased_adminhtml_index_index>
        <reference name="content">
            <block type="regionbased/adminhtml_regionbased"  name="regions" template="regionbased/index.phtml"/>
        </reference>
    </regionbased_adminhtml_index_index>
</layout>

block file:

<?php

class Ilogix_Regionbased_Block_Adminhtml_Regionbased extends Mage_Adminhtml_Block_Template
{
    public function __construct()
    {
        parent::__construct();
    }

}

config.xml file

 <global>
        <blocks>
            <regionbased>
                <class>Ilogix_Regionbased_Block</class>
            </regionbased>
        </blocks>
 </global>
