sap.m.table multi checkbox make it READ ONLY - On Condition + SAP UI5 - sapui5

Question

This is my first post to Stack, appreciate the work you guys do, amazing.
I have a sap.m.table sap ui5 and i have 4 records
out of 4, 2 are selected by default, i want to disable the preselected once based on condition.
I have tried below code but its not working, any input please?
View
/results' }" **mode="MultiSelect"**
Controller logic
//--->disable the selected department checkboxes
var tbl = that.getView().byId('idImpactTable');
var header = tbl.$().find('thead');
var selectAllCb = header.find('.sapMCb');
selectAllCb.remove();
tbl.getItems().forEach(function(r) {
var obj = r.getBindingContext("impactModel").getObject();
var oStatus = obj.COMPLETED;
var cb = r.$().find('.sapMCb');
var oCb = sap.ui.getCore().byId(cb.attr('id'));
if (oStatus === "X") {
oCb.setSelected(true);
oCb.setEnabled(false);
} else {
oCb.setEnabled(false);
}
});
Multiselect Mode Table - Make selected check box read only

Answer 1

Last time I tried this I found it easiest to use the updateFinished event on the table, and then use an internal property of the column list item, like so:
onTableUpdateFinished: function (oEvent) {
oEvent.getSource().getItems().forEach(function (item) {
var data = item.getBindingContext().getObject();
item._oMultiSelectControl.setEnabled(!data.IsEnabled); //whatever your check is
});
}
You'll have to find a way to keep them disabled though when using the Select All checkbox at the top of the table. I ended up extending sap.m.Table to accomplish that, there might be easier ways...
My extension is like this
sap.ui.define([
"sap/m/Table"
], function(Control) {
return Control.extend("myapp.controls.MyTable", {
updateSelectAllCheckbox: function(oEvent) {
if (this._selectAllCheckBox && this.getMode() === "MultiSelect") {
var aItems = this.getItems();
var iSelectedItemCount = this.getSelectedItems().length;
var iSelectableItemCount = aItems.filter(function(oItem) {
//standard table does not check if the item is enabled
return oItem.getSelected() || oItem._oMultiSelectControl.getEnabled();
}).length;
// set state of the checkbox by comparing item length and selected item length
this._selectAllCheckBox.setSelected(aItems.length > 0 && iSelectedItemCount === iSelectableItemCount);
}
}
});
});
And just the standard renderer
sap.ui.define([
"sap/m/TableRenderer"
], function(Control) {
return Control.extend("myapp.controls.MyTableRenderer", {
});
});
I suppose I could have extended the ColumnListItem but that was more effort than I wanted to put into the table extension

I have managed to find the solution, please find sample code to achieve.
//--->disable the selected department checkboxes
var tbl = that.getView().byId("idImpactTable");
var header = tbl.$().find("thead");
var selectAllCb = header.find(".sapMCb");
selectAllCb.remove();
var aItems = that.byId("idImpactTable").getItems();
//---> Check individual item property value and select the item
aItems.forEach(function(oItem) {
debugger;
//---> If using OData Model items Binding, get the item object
var mObject = oItem.getBindingContext().getObject();
var sPath = oItem.getBindingContextPath();
var completed = oItem.oBindingContexts.impactModel.getProperty("COMPLETED");
//--->get the id of Multi Checkbox
var cb = oItem.$().find(".sapMCb");
var oCb = sap.ui.getCore().byId(cb.attr("id"));
if (completed === "X") {
oCb.setEditable(false);
oItem.setSelected(true);
oItem.getCells()[4].setEnabled(false);
} else {
oItem.setSelected(false);
}
});
Thank you,

//--->disable the selected department checkboxes
var tbl = that.getView().byId('idImpactTable');
tbl.getItems().forEach(function(r) {
// this makes the trick --->
var oMultiSelCtrl = r.getMultiSelectControl();
oMultiSelCtrl.setDisplayOnly( true );
});
