+# How to Scroll and Select the Record Programmatically in WPF / UWP TreeGrid?
+
+This example illustrates how to scroll and select the record programmatically in [WPF TreeGrid](https://www.syncfusion.com/wpf-controls/treegrid) and [UWP TreeGrid](https://www.syncfusion.com/uwp-ui-controls/treegrid) (SfTreeGrid).
+
+You can scroll to the record programmatically using the [ScrollInView](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.TreeGrid.SfTreeGrid.html#Syncfusion_UI_Xaml_TreeGrid_SfTreeGrid_ScrollInView_Syncfusion_UI_Xaml_ScrollAxis_RowColumnIndex_) method by passing the row index of the record. You can get the row index of the record using the [ResolveToRowIndex](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.TreeGrid.TreeGridIndexResolver.html#Syncfusion_UI_Xaml_TreeGrid_TreeGridIndexResolver_ResolveToRowIndex_Syncfusion_UI_Xaml_TreeGrid_SfTreeGrid_Syncfusion_UI_Xaml_TreeGrid_TreeNode_) extension method present in **Syncfusion.UI.Xaml.TreeGrid.Helpers**.
+
+You can select the record programmatically by setting the [SelectedItem](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.Grid.SfGridBase.html#Syncfusion_UI_Xaml_Grid_SfGridBase_SelectedItem) property in TreeGrid.
+
+``` c#
+private void Treegrid_Loaded(object sender, System.Windows.RoutedEventArgs e)
+{
+    var selectedItem = (this.treegrid.DataContext as ViewModel).SelectedItem;
+    var rowindex = this.treegrid.ResolveToRowIndex(selectedItem);
+    var columnindex = this.treegrid.ResolveToStartColumnIndex();
+    //Make the row in to available on the view. 
+    this.treegrid.ScrollInView(new RowColumnIndex(rowindex, columnindex));
+    //Set the SelectedItem in SfTreeGrid.
+    this.treegrid.SelectedItem = selectedItem;
+}
+```
