NOTE

Default value of toolbar items is [‘OpenOption’, ‘PageNavigationTool’,’MagnificationTool’, ‘PanTool’, ‘SelectionTool’, ‘SearchOption’, ‘PrintOption’, ‘DownloadOption’,’UndoRedoTool’, ‘AnnotationEditTool’, ‘FormDesignerEditTool’, ‘CommentTool’, ‘SubmitForm’]

Align Property

The align property is used to specify the alignment of a toolbar item within the toolbar.

Left: Aligns the item to the left side of the toolbar.
Right: Aligns the item to the right side of the toolbar.

The tooltip property is used to set the tooltip text for a toolbar item. Tooltip provides additional information when a user hovers over the item.

CssClass Property

The cssClass property is used to apply custom CSS classes to a toolbar item. It allows custom styling of the toolbar item.

Prefix Property

The prefix property is used to set the CSS class or icon that should be added as a prefix to the existing content of the toolbar item.

ID Property

The id property within a CustomToolbarItemModel is a compulsory attribute that plays a vital role in toolbar customization. It serves as a unique identifier for each toolbar item, facilitating distinct references and interactions.

When defining or customizing toolbar items, it is mandatory to assign a specific and descriptive id to each item.
These properties are commonly used when defining custom toolbar items with the CustomToolbarItemModel in the context of Syncfusion^® PDF Viewer. When configuring the toolbar using the ToolbarSettings property, you can include these properties to customize the appearance and behavior of each toolbar item.

NOTE

When customizing toolbar items, you have the flexibility to include either icons or text based on your design preference.

View sample in GitHub

The PDF Viewer provides API for user interactions options provided in its built-in toolbar. Using this, you can create your own User Interface for toolbar actions at the application level by hiding the built-in 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 a simple PDF Viewer sample.

Step 2: Hide the built-in toolbar of PDF Viewer using the following code snippet.,

Standalone
Server-Backed
<ejs-pdfviewer #pdfviewer id='pdfViewer'
               [documentPath]='document'
               [enableToolbar]=false
               [enableNavigationToolbar]=false
               (pageChange)='pageChanged($event)'
               (documentLoad)='documentLoaded($event)'
               style="height:640px; display: block">
</ejs-pdfviewer>
<ejs-pdfviewer #pdfviewer id='pdfViewer'
               [serviceUrl]='service'
               [documentPath]='document'
               [enableToolbar]=false
               [enableNavigationToolbar]=false
               (pageChange)='pageChanged($event)'
               (documentLoad)='documentLoaded($event)'
               style="height:640px; display: block">
</ejs-pdfviewer>

Step 3: Add EJ2 toolbar for performing primary actions like Open, Previous page, Next page, Go to page, Print and Download using the following code snippet.

<ejs-toolbar id='topToolbar' #customToolbar>
    <e-items>
        <e-item prefixIcon='e-pv-open-document-icon' id='openDocument' tooltipText='Open' (click)='openDocument($event)'>
        </e-item>
        <e-item prefixIcon='e-pv-previous-page-navigation-icon' id='previousPage' tooltipText='Previous Page' (click)='previousClicked($event)'
                align='Center'></e-item>
        <e-item prefixIcon='e-pv-next-page-navigation-icon' id='nextPage' tooltipText='Next Page' (click)='nextClicked($event)' align='Center'></e-item>
        <e-item align='Center'>
            <ng-template #template>
                <div class=''>
                    <input type='text' class='e-input-group e-pv-current-page-number' id='currentPage' value="0"
                           (keypress)='onCurrentPageBoxKeypress($event)' (click)='onCurrentPageBoxClicked($event)' />
                </div>
                <div style='margin-left: 6px'><span class='e-pv-total-page-number' id='totalPage'>of 0</span></div>
            </ng-template>
        </e-item>
        <e-item prefixIcon='e-pv-print-document-icon' tooltipText='Print' (click)='printClicked($event)' align='Right'></e-item>
        <e-item prefixIcon='e-pv-download-document-icon' tooltipText='Download' (click)='downloadClicked($event)' align='Right'></e-item>
    </e-items>
</ejs-toolbar>
<input type="file" id="fileUpload" accept=".pdf" style="display:block;visibility:hidden;width:0;height:0;">

Step 3: Add EJ2 toolbar for performing magnification actions in PDF Viewer using the following code snippet.

<ejs-toolbar id='magnificationToolbar' #zoomToolbar>
    <e-items>
        <e-item prefixIcon='e-pv-fit-page-icon' id='fitPage' tooltipText='Fit to page' (click)='pageFitClicked($event)'></e-item>
