Just a little piece of code would be appreciated in order to understand the problem... just the code you used. If you used winform, maybe, even the designer.cs file.

You have an "enable/disable all" kind of textbox in the header, why textbox? It offers no control to what a user can enter, including typo. Why not a dropdownlist with approve and reject items for selection.
Your checkbox idea may confuse the users, you may want to re-think and re-work.

This could be achieved by using javascript.

Javascript for select/unselect checkbox:

JavaScript

function selectAllCheckBox(event, containerId, boolChecked) {
    var collection = document.getElementById(containerId).getElementsByTagName('INPUT');
    for (var x = 0; x < collection.length; x++) {
        if (collection[x].type.toUpperCase() == 'CHECKBOX')
            collection[x].checked = boolChecked;
    }
    event.preventDefault();
    return false;
}

Javascript for updating all textbox:

JavaScript

function changeReadOnly(event,containerId,isReadOnly) {
	var collection = document.getElementById(containerId).getElementsByTagName('INPUT');
    for (var x = 0; x < collection.length; x++) {
        if (collection[x].type.toUpperCase() == 'TEXT')
            collection[x].readOnly = isReadOnly;
    }
    event.preventDefault();
    return false;
}

Sample HTML:

HTML

<input type="submit" value="select all" onclick="return selectAllCheckBox(event,'divGrid', true);">
<input type="submit" value="select none" onclick="return selectAllCheckBox(event,'divGrid', false);">
<input type="submit" value="Read Only = true" onclick="return changeReadOnly(event,'divGrid',true);">
<input type="submit" value="Read Only = false" onclick="return changeReadOnly(event,'divGrid',false);">



<div id="divGrid">

<!--GridView goes here-->

</div>
