How to remove save and reset button from edit form?

Question

In custom module I have one grid. in that grid i don't want to edit data from admin panel. I want to just view of that data so i want to remove save button and reset button.

In Edit.php

public function __construct()
{
    parent::__construct();
    $this->_objectId = "example_id";
    $this->_blockGroup = "example";
    $this->_controller = "adminhtml_example";
    // $this->_updateButton("save", "label", Mage::helper("example")->__("Save Tutor"));
    $this->_updateButton("delete", "label", Mage::helper("example")->__("Delete Tutor"));

    /**
    $this->_addButton("saveandcontinue", array(
        "label"     => Mage::helper("example")->__("Save And Continue Edit"),
        "onclick"   => "saveAndContinueEdit()",
        "class"     => "save",
    ), -100);

    $this->_formScripts[] = "
        function saveAndContinueEdit() {
            editForm.submit($('edit_form').action+'back/edit/');
        }
    ";
    */
}   

I m comment code of save button and saveAndContinueEdit button but save button is display.

I know another way to admin can't save data using disable set as true in all addfield but i want to remove add button and reset button if possible and i want to remove this button using custom module.

Answer 1

Add this in the method you mentioned

$this->_removeButton('save');
$this->_removeButton('delete');
$this->_removeButton('reset');

Note that Magento does not want you to override the __construct method. You should override the _construct method instead. One problem is that you cannot remove buttons in the _construct method. But you can simply override the _prepareLayout method for that purpose:

protected function _prepareLayout()
{
    $this->_removeButton('save');
    $this->_removeButton('delete');
    $this->_removeButton('reset');

    return parent::_prepareLayout();
}

To remove buttons on MAGENTO 2 admin form:

$this->buttonList->remove('delete');
$this->buttonList->remove('save');
$this->buttonList->remove('reset');
$this->buttonList->remove('back');
