Introduction Download PDF In Dynamics 365

In this blog, i will show how to download latest file generated in the timeline when click on ribbon workbench button on Dynamics 365

For this i have created a button using ribbon workbench

when click on this button it needs to download the file immediately from the timeline

Code i have used
Call this code from ribbon workbench button

function downloadLatestPDFFromTimeline(formContext) {

var entityId = formContext.data.entity.getId();

var globalContext = Xrm.Utility.getGlobalContext();

var requestUrl =

globalContext.getClientUrl() +

“/api/data/v9.1/annotations?$select=filename,documentbody,mimetype&$filter=_objectid_value eq ” +

entityId +

” and filename ne null and endswith(filename, ‘.pdf’)&$orderby=createdon desc&$top=1″;

var req = new XMLHttpRequest();

req.open(“GET”, requestUrl, true);

req.setRequestHeader(“OData-MaxVersion”, “4.0”);

req.setRequestHeader(“OData-Version”, “4.0”);

req.setRequestHeader(“Accept”, “application/json”);

req.setRequestHeader(“Content-Type”, “application/json; charset=utf-8”);

req.onreadystatechange = function () {

if (this.readyState === 4) {

if (this.status === 200) {

var response = JSON.parse(this.responseText);

if (response.value && response.value.length > 0) {

var latestDocument = response.value[0];

var documentUrl = latestDocument.documentbody;

var fileName = latestDocument.filename;

// Create a Blob from the document body

var byteCharacters = atob(documentUrl);

var byteNumbers = new Array(byteCharacters.length);

for (var i = 0; i < byteCharacters.length; i++) {

byteNumbers[i] = byteCharacters.charCodeAt(i);

}

var byteArray = new Uint8Array(byteNumbers);

var blob = new Blob([byteArray], { type: ‘application/pdf’ });

// Create a download link and trigger the download

var a = document.createElement(‘a’);

a.href = URL.createObjectURL(blob);

a.download = fileName;

a.style.display = ‘none’;

document.body.appendChild(a);

a.click();

document.body.removeChild(a);

} else {

alert(“No PDF documents found in the timeline for this Quote.”);

}

} else {

alert(“Error retrieving the latest PDF document: ” + this.status + ” – ” + this.statusText);

}

};

req.send();

}

Now once i click on the download doc button it will immediately download the latest file from the timeline
