In this post, I am explaining how to query data from a CDS entity and use Knockout to bind it in a model-driven app web resource.
It has the following advantages:
- It is easy but doesn’t require a lot of efforts (less coding)
- We have the flexibility to do further customisation
About the Demo
Since it is demo, I have included script and link references from CDN. The focus of this post is to explain and share sample code for data binding. I'm loading my web resource as a popup and have used AlertJS‘s free version for this. To keep this post short, I'm not explaining how to add a button in Model-Driven App. But to summarise steps, I have added JS file in my form, customised ribbon and added a button with the following code:
"use strict";
var Account = (function ()
{
return {
LoadAccountsPopup: function (executionContext)
{
Alert.showWebResource("webresource_accounts");
}
}
})();
In my web resource, I'm getting data using Web API query. Data binding is done of course using Knockout and I have used Bootstrap for styling. Here is the code:

$.getJSON(oDataUrl)
.done(function (data) {
if (data != undefined && data.value.length > 0) {
ko.applyBindings(new AppViewModel(data));
debugger;
}
})
.fail(function (error) {
debugger;

});
function AppViewModel(data) {
var self = this;
self.pingResults = ko.observableArray([]);
ko.utils.arrayForEach(data.value, function (d) {
self.pingResults.push(d);
});
}
</script>
