+# Enable or Disable Text Selection in Syncfusion PDF Viewer
+
+The Syncfusion PDF Viewer provides the `EnableTextSelection` property, which allows you to control whether users can select text within the displayed PDF document. This feature can be toggled programmatically during runtime.
+
+## Configure Text Selection on Initialization
+
+You can set the initial text selection behavior when initializing the PDF Viewer control by configuring the `EnableTextSelection` property. By default, text selection is enabled, but you can disable it as shown in the following example:
+
+{% tabs %}
+{% highlight html tabtitle="Standalone" %}
+
+@using Syncfusion.EJ2
+@{
+    ViewBag.Title = "Home Page";
+}
+
+<div>
+    <div style="height:500px;width:100%;">
+        @Html.EJS().PdfViewer("pdfviewer")
+            .DocumentPath("https://cdn.syncfusion.com/content/pdf/pdf-succinctly.pdf")
+            .ResourceUrl("https://cdn.syncfusion.com/ej2/30.1.37/dist/ej2-pdfviewer-lib")
+            .EnableTextSelection(false)
+            .Render()
+    </div>
+</div>
+
+{% endhighlight %}
+{% endtabs %}
+
+## Toggle Text Selection Dynamically
+
+You can change the text selection behavior at runtime using buttons, menu options, or other UI elements. The following example demonstrates how to toggle text selection with button clicks:
+
+{% tabs %}
+{% highlight html tabtitle="Standalone" %}
+
+@using Syncfusion.EJ2
+@{
+    ViewBag.Title = "Home Page";
+}
+
+<div>
+    <div style="height:500px;width:100%;">
+        <button onclick="enableTextSelection()">EnableTextSelection</button>
+        <button onclick="disableTextSelection()">DisableTextSelection</button>
+        @Html.EJS().PdfViewer("pdfviewer")
+            .DocumentPath("https://cdn.syncfusion.com/content/pdf/pdf-succinctly.pdf")
+            .ResourceUrl("https://cdn.syncfusion.com/ej2/30.1.37/dist/ej2-pdfviewer-lib")
+            .EnableTextSelection(false)
+            .Render()
+    </div>
+</div>
+
+<script type="text/javascript">
+    function enableTextSelection() {
+        var viewer = document.getElementById('pdfviewer').ej2_instances[0];
+        viewer.enableTextSelection = true;    
+    }
+
+    function disableTextSelection() {
+        var viewer = document.getElementById('pdfviewer').ej2_instances[0];
+        viewer.enableTextSelection = false; 
+    }
+</script>
+
+{% endhighlight %}
+{% endtabs %}
+
+## Use Cases and Considerations
+
+- **Document Protection**: Disabling text selection helps prevent unauthorized copying of sensitive content.
+- **Read-only Documents**: In scenarios where documents are meant for viewing only, disabling text selection can provide a cleaner user experience.
+- **Interactive Applications**: Toggle text selection based on user roles or document states in complex applications.
+- **Controlled Access**: Implement conditional text selection depending on user permissions or document sections.
+
+## Default Behavior
+
+By default, text selection is enabled in the PDF Viewer. Set the `EnableTextSelection` property to `false` explicitly if you want to disable this functionality.
+
+N> When text selection is disabled, users will not be able to select or copy text from the document, which can be useful for protecting document content in certain scenarios.
