+# How to filter the node based on the node ID in WinForms TreeViewAdv
+
+This session describes how to filter the node based on the nodeID in [WinForms TreeViewAdv](https://www.syncfusion.com/winforms-ui-controls/treeview).
+
+In the `TreeViewAdv`, [TreeNodeAdv](https://help.syncfusion.com/cr/windowsforms/Syncfusion.Tools.Windows~Syncfusion.Windows.Forms.Tools.TreeNodeAdv.html) can be filtered based on its value by performing the iteration process. The following code example demonstrates the same.
+
+``` csharp
+for(int nodeId = 0; nodeId <= 10000; nodeId++)
+{
+     //Custom node for ID propety
+    CustomTreeNodeAdv customNode = new CustomTreeNodeAdv();
+    customNode.ID = nodeId;
+    customNode.Text = "Node" + nodeId.ToString();
+    this.treeViewAdv1.Nodes.Add(customNode);
+}
+//Iterates the nodes in the TreeViewAdv
+foreach (CustomTreeNodeAdv item in this.treeViewAdv1.Nodes)
+{
+    //Gets the TextBox value
+    string textvalue = item.ID.ToString();
+    if(this.integerTextBox1.Text == textvalue)
+    {
+       //Gets the node by its ID
+       MessageBox.Show(item.Text);
+    }
+}
+```
