Customization in EJ2 JavaScript Pdfviewer control
16 Dec 202324 minutes to read
The PDF Viewer provides API for user interactions options provided in it’s built-in toolbar. Using this we can create our own User Interface for toolbar actions in application level by hiding the default toolbar. The following steps are used to create the custom toolbar for PDF Viewer,
Step 1: Follow the steps provided in the link to create simple PDF Viewer sample.
Step 2: Now, add an HTML div element to render the PDF Viewer with custom toolbar using the following code.

<div id='searchContainer'>
<span class="e-input-group e-custom-search-input">
<input type="text" id="searchInput" placeholder="Find in document" class="e-input" />
<span class="e-input-group-icon e-pv-search-icon" id="searchBtn"></span>

</div>
<div id="matchCaseContainer" style="margin-top:8px">
<input id="matchCase" type="checkbox" />
</div>
</div>
</body>
</html>Step 3: Hide the default toolbar of PDF Viewer using below code snippet,
```javascript
var pdfviewer = new ej.pdfviewer.PdfViewer({
enableToolbar: false,
enableThumbnail: false,
documentPath: "https://cdn.syncfusion.com/content/pdf/hive-succinctly.pdf"
});
ej.pdfviewer.PdfViewer.Inject(ej.pdfviewer.TextSelection, ej.pdfviewer.TextSearch, ej.pdfviewer.Navigation,ej.pdfviewer.Print);
pdfviewer.appendTo('#PdfViewer');
``````javascript
var pdfviewer = new ej.pdfviewer.PdfViewer({
enableToolbar: false,
enableThumbnail: false,
documentPath: "https://cdn.syncfusion.com/content/pdf/pdf-succinctly.pdf",
serviceUrl: 'https://services.syncfusion.com/js/production/api/pdfviewer'
});
ej.pdfviewer.PdfViewer.Inject(ej.pdfviewer.TextSelection, ej.pdfviewer.TextSearch, ej.pdfviewer.Navigation,ej.pdfviewer.Print);
pdfviewer.appendTo('#PdfViewer');
```Step 4: Add EJ2 Toolbar for perform primary actions like Open, Previous page, Next page, Go to page,Print and Download using the following code snippet,
var toolbarObj = new ej.navigations.Toolbar({
items: [
{ prefixIcon: 'e-pv-open-document', tooltipText: 'Open', id: 'openButton', click: openClicked },
{ prefixIcon: 'e-pv-bookmark-icon', tooltipText: 'Bookmark', id: 'bookmarkButton', click: bookmarkClicked },
{ prefixIcon: 'e-pv-previous-page-navigation-icon', id: 'previousPage', tooltipText: 'Previous Page', align: 'Center', click: previousClicked.bind(this) },
{ prefixIcon: 'e-pv-next-page-navigation-icon', id: 'nextPage', tooltipText: 'Next Page', align: 'Center', click: nextClicked.bind(this) },
{ template: inputTemplate, tooltipText: 'Page Number', align: 'Center' },
{ template: ele, tooltipText: 'Page Number', align: 'Center' },
{ prefixIcon: 'e-pv-search-icon', tooltipText: 'Text Search', align: 'Right', click: searchClicked.bind(this) },
{ prefixIcon: 'e-pv-print-document-icon', tooltipText: 'Print', align: 'Right', click: printClicked.bind(this) },
{ prefixIcon: 'e-pv-download-document-icon', tooltipText: 'Download', align: 'Right', click: downloadClicked.bind(this) }
]
});
toolbarObj.appendTo('#topToolbar');
var magnificationToolbar = new ej.navigations.Toolbar({
items: [
{ prefixIcon: 'e-pv-fit-page-icon', id: 'fitPage', tooltipText: 'Fit to page', click: pageFitClicked.bind(this) },
{ prefixIcon: 'e-pv-zoom-in-icon', id: 'zoomIn', tooltipText: 'Zoom in', click: zoomInClicked.bind(this) },
{ prefixIcon: 'e-pv-zoom-out-icon' , id: 'zoomOut', tooltipText: 'Zoom out', click: zoomOutClicked.bind(this) },
]
});
magnificationToolbar.appendTo('#magnificationToolbar');Step 5: Add the following style to achieve the custom toolbar styling,
