I hope this helps you . If both isEquityUS and EQUS are part of the model of kendogrid, then instead of using inline template, you can define the template in your html.
code :
<script id="template" type="text/kendo-template">
   #if(EQUS != '') { #   
   <input type="checkbox" #= data.IsEquityUS ? checked="checked" : "" # />
   # } #
</script>
 columns: [
    { field: "EQUS", Title: "EQUS", width: 150 },
    {
        template: $("#template").html(),

    }
]

wish help you to fix your issue Checkboxes in a `Grid are little tricky since you cannot update them (click in the checkbox) without entering in edit mode.
If you do not take this into account, you see the checkbox marked but the model is actually not updated so when you load new data (page, scroll, filter...) the changes get lost.
code :
template: "<input class='ob-checkbox' type='checkbox' #= Checkbox ? 'checked' : '' #/>",
grid.wrapper.on("click", ".ob-checkbox", function(e) {
    // Get the row containing the checkbox
    var row = $(e.currentTarget).closest("tr");
    // Get the item in the model corresponding to that row
    var item = grid.dataItem(row);
    // Get current value of the rendered checkbox (not the value in the model)
    var value = this.checked;
    // And update the model
    item.set("Checked", value);
});
var grid = $(gridName).data("kendoGrid");

I wish this help you First, remove the box.Checked = ... code from CreateCheckBox. It does not belong there. You will modify the Checked-state on postbacks even if the chkSetAllActive-CheckBox wasn't clicked.
You should handle the CheckedChanged event of the chkSetAllActive in this way:
code :
var allChk = PlaceHolder1.Controls.OfType<CheckBox>()
    .Where(chk => chk.Text == "Active"); // to avoid problems
foreach(CheckBox chk in allChk)
    chk.Checked = chkSetAllActive.Checked;
foreach(Control ctrl in PlaceHolder1.Controls)
{
    CheckBox chk = ctrl as CheckBox;
    if(chk != null && chk.Text == "Active")
        chk.Checked = chkSetAllActive.Checked;
}

To fix the issue you can do We made this in out own application also, we added a class to the header: $('.calculation-selection-checkbox')
and attached a click event on this class which goes to this event:
code :
 projects.handleCheckBoxHeaderClicked = function (clickEvent) {
    var checkBoxes = $('.calculation-selection-checkbox');
    var element = $(this.children[0]);
    var value = element.html();
    if (value.charCodeAt(0) === 9745) {
        localStorageManager.removeAll();
        checkBoxes.prop('checked', false);
        element.html('&#x2610;');
    } else {
        localStorageManager.addAll();
        checkBoxes.prop('checked', true);
        element.html('&#x2611;');
    }
};
columns.Template(@<text>
<label class="checkbox-radiobutton">

    <input type="checkbox" data-id="@item.CalculationId" name="selectThisProject" 
class="checkbox calculation-selection-checkbox checkbox-radiobutton"><span></span></label>  
</text>).Title("&#x2610;")
.HeaderHtmlAttributes(new { @class = "check-box-header" }).Width("30px");
   projects.initializeCheckBoxes = function () {
        if (projects.allSelected) {
            var isChecked = (projects.allSelected === "true");
            var checkBoxes = $('.calculation-selection-checkbox');
            var i;
            var element = $('.check-box-header')[0];
            checkBoxes.prop('checked', isChecked);
            var checkBox = $('.checkbox');
            for (i = 0; i < checkBox.length; i++) {
                var id = $(checkBox[i]).data('id');
                if (!localStorageManager.exists(id)) {
                    $(checkBox[i]).prop('checked', false);
                } else if (localStorageManager.exists(id)) {
                    $(checkBox[i]).prop('checked', true);
                    $("#EdreamsPanel").removeClass("hidden");
                }

            }
            if (isChecked)
                $(element).html('<span class="k-link">&#x2611;</span>');
        }
    };
 projects.handleCheckBoxHeaderClicked = function (clickEvent) {
        var checkBoxes = $('.calculation-selection-checkbox');
        var element = $(this.children[0]);
        var value = element.html();
        if (value.charCodeAt(0) === 9745) {
            localStorageManager.removeAll();
            checkBoxes.prop('checked', false);
            element.html('&#x2610;');
        } else {
            localStorageManager.addAll();
            checkBoxes.prop('checked', true);
            element.html('&#x2611;');
        }
    };
Is there better way to show and hide lots of elements and uncheck checkboxes on hide?

seems to work fine The single best change you could make would be to make use of the ternary operator (reference). The ternary operator is an efficient short-hand approach to writing If/Else statements, which your script is heavy on.
The ternary operator essentially works by taking a condition first (e.g. your IF statement), followed by an expression to evaluate when that condition is true and then finally what an expression to evaluate when the condition is false. This is stylized as: condition ? expr1 : expr2.
code :
if (relativeYes.checked) {
    document.getElementById('relativeConditions').style.display = 'block';
  }
else {
    document.getElementById('relativeConditions').style.display = 'none';
  }
relativeYes.checked ? document.getElementById('relativeConditions').style.display = 'block' : document.getElementById('relativeConditions').style.display = 'none';
