 # How-to-Prevent-SfComboBox-Dropdown-from-Closing-Unexpectedly-When-Resizing-in-.NET-MAUI
 This repository contains a sample explaining how to Prevent SfComboBox Dropdown from Closing Unexpectedly When Resizing in .NET MAUI
+## Solution
+To prevent the dropdown from closing during resizing, use the following approach:
+
+1. Track layout resizing using a flag.
+2. Override `OnSizeAllocated` to detect when the layout is resized.
+3. Handle the `DropDownClosing` event to prevent closing during resizing.
+
+## Implementation
+
+**C# Code**
+```csharp
+public partial class MainPage : ContentPage
+{
+    private bool isResizing; // Flag to track resizing
+
+    public MainPage()
+    {
+        InitializeComponent();
+        App.Current.On<Microsoft.Maui.Controls.PlatformConfiguration.Android>().UseWindowSoftInputModeAdjust(WindowSoftInputModeAdjust.Resize);
+    }
+
+    protected override void OnSizeAllocated(double width, double height)
+    {
+        base.OnSizeAllocated(width, height);
+        isResizing = true;
+    }
+
+    private async void SfComboBox_DropDownClosing(object sender, Syncfusion.Maui.Core.DropDownCancelEventArgs e)
+    {
+        if (isResizing)
+        {
+            e.Cancel = true; // Prevent closing during resizing
+        }
+
+        await Task.Delay(400); // Short delay to update UI after resizing
+        isResizing = false;
+    }
+}
+```
+
+**XAML**
+```xml
+<ScrollView>
+    <VerticalStackLayout>
+        <editors:SfComboBox x:Name="comboBox"
+                            Placeholder="Select an item"
+                            DropDownClosing="SfComboBox_DropDownClosing">
+            <editors:SfComboBox.ItemsSource>
+                <x:Array Type="{x:Type x:String}">
+                    <x:String>Apple</x:String>
+                    <x:String>Banana</x:String>
+                    <x:String>Cherry</x:String>
+                </x:Array>
+            </editors:SfComboBox.ItemsSource>
+        </editors:SfComboBox>
+    </VerticalStackLayout>
+</ScrollView>
+```
