 # How-to-bind-SelectedItem-property-in-Winforms-SfComboBox
-This session explains how to  bind SelectedItem property in Winforms SfComboBox
+This example demonstrates how to **bind the SelectedItem property** of the **Syncfusion WinForms SfComboBox** control to another property in your application. Binding the SelectedItem property is useful when you want to synchronize the selected value in the combo box with a property in your data model or view model. This ensures that any changes in the UI are reflected in the underlying data and vice versa.
+
+## Why Use Data Binding?
+Data binding simplifies the process of keeping the UI and data model in sync. When you bind the SelectedItem property:
+- The selected item in the combo box updates automatically when the bound property changes.
+- Any user selection in the combo box updates the bound property without additional code.
+
+## Implementation Steps
+1. **Prepare the ViewModel**: Create a ViewModel class with a collection of items and a property to hold the selected item.
+2. **Configure SfComboBox**:
+   - Set the `DataSource` to the collection of items.
+   - Define `DisplayMember` and `ValueMember` for proper display and value mapping.
+3. **Bind SelectedItem**:
+   - Use the `DataBindings.Add` method to bind the SelectedItem property of SfComboBox to the ViewModel property.
+
+## Example Code
+```csharp
+public Form1()
+{
+    InitializeComponent();
+    ViewModel viewModel = new ViewModel();
+    sfComboBox1.DataSource = viewModel.Items;
+    sfComboBox1.DisplayMember = "LongName";
+    sfComboBox1.ValueMember = "ShortName";
+    sfComboBox1.DataBindings.Add(new Binding("SelectedItem", viewModel, "Selected", true, DataSourceUpdateMode.OnPropertyChanged));
+}
+```
+
+This code binds the `SelectedItem` property of `sfComboBox1` to the `Selected` property in the ViewModel. The binding uses `DataSourceUpdateMode.OnPropertyChanged` to ensure updates occur immediately when the property changes.
