+# How to bring the tree node into view by scrolling in WPF TreeView
+
+This repository describes how to bring the tree node into view by scrolling in [WPF TreeView](https://www.syncfusion.com/wpf-controls/treeview) (SfTreeView).
+
+The TreeView allows programmatic scrolling based on the data model and [TreeViewNode](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.TreeView.Engine.TreeViewNode.html) by using the [BringIntoView](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.TreeView.SfTreeView.html#Syncfusion_UI_Xaml_TreeView_SfTreeView_BringIntoView_Syncfusion_UI_Xaml_TreeView_Engine_TreeViewNode_System_Boolean_System_Boolean_Syncfusion_UI_Xaml_TreeView_ScrollToPosition_) method.
+
+``` csharp
+private void BringIntoView_Click(object sender, RoutedEventArgs e)
+{
+    var count = viewModel.Items.Count;
+    var data = viewModel.Items[count - 1];
+    sfTreeView.BringIntoView(data);
+}
+```
+
+The `BringIntoView` method comprises of other optional parameters to decide on the way in which the child item should come into view.
+
+### Scroll to the child item with animation
+
+The second optional parameter `disableAnimation` in `BringIntoView` method decides whether the scrolling animation should be enabled or disabled when the child item comes into view. By default, the scrolling will be animated.
+
+* If the parameter value is `true`, scrolling animation will be disabled.
+* If the parameter value is `false`, scrolling animation will be enabled.
+
+``` csharp
+private void BringIntoView_Click(object sender, RoutedEventArgs e)
+{
+    var count = viewModel.Items.Count;
+    var data = viewModel.Items[count - 1];
+    // Here, the second optional parameter has been passed as true hence it will disable the animation
+    sfTreeView.BringIntoView(data, true);
+}
+```
+
+### Scroll to the collapsed child item
+
+The third optional parameter `canExpand` in `BringIntoView` method decides whether we need to expand and show the collapsed node or not when item passed for `BringIntoView` method which is in collapsed state. By default, this parameter value will be false.
+
+* If the parameter value is `true`, TreeView expands the collapsed node if it is collapsed and scroll to the specified item.
+* If the parameter value is `false`, TreeView does not expand the collapsed node and only scroll for item which is not in collapsed state.
+
+``` csharp
+private void BringIntoView_Click(object sender, RoutedEventArgs e)
+{
+    var count = viewModel.Items.Count;
+    var data = viewModel.Items[count - 1];
+    sfTreeView.BringIntoView(data, false,true);
+}
+```
+
+### Scroll the item into specified position
+
+The fourth optional parameter `scrollToPosition` in `BringIntoView` method allows to position the scrolled item in the view. The scrolled item can take either of the four positions as explained below. The default position is `Start`.
+
+* `Start`: Scroll to make the node positioned at the start of the view.
+* `MakeVisible`: Scroll to make a specified node visible in the view. If the specified node is already in view, scrolling will not occur.
+* `Center`: Scroll to make the node positioned at the center of the view.
+* `End`: Scroll to make the node positioned at the end of the view.
+
+``` csharp
+private void BringIntoView_Click(object sender, RoutedEventArgs e)
+{
+    var count = viewModel.Items.Count;
+    var data = viewModel.Items[count - 1];
+    // Scrolls to the data item to make visible in the view.
+    sfTreeView.BringIntoView(data,false,true,ScrollToPosition.MakeVisible);
+}
+```
