+## Changing forecolor for disabled items in dropdown
+You can change the forecolor for disabled items by handling SfComboBox.DropDownListView.DrawItem event to show the items is disabled.
+
+# C#
+
+    sfComboBox.DropDownListView.DrawItem += DropDownListView_DrawItem;
+
+    private void DropDownListView_DrawItem(object sender, Syncfusion.WinForms.ListView.Events.DrawItemEventArgs e)
+        {
+            bool isItemEnable = (this.sfComboBox.ComboBoxMode == ComboBoxMode.MultiSelection && this.sfComboBox.AllowSelectAll && e.ItemIndex == 0) ? true : (e.ItemData as Details).IsEnabled;
+        if (!isItemEnable)
+        {
+             e.Style.BackColor = Color.LightGray;
+             e.Style.ForeColor = Color.Gray;
+        }
+    }
+
+## Handling selection for disabled items in dropdown
+Selection of disabled items in multi selection mode handled using SfComboBox.DropDownListView.SelectionChanged and SfComboBox.DropDownListView.ItemChecking event. In single selection mode, selection is handled using SfComboBox.DropDownListView.SelectionChanging event.
+
+# C#
+
+    private void DropDownListView_SelectionChanged(object sender, Syncfusion.WinForms.ListView.Events.ItemSelectionChangedEventArgs e)
+        {
+            if (e.AddedItems.Count == this.sfComboBox.DropDownListView.View.Items.Count)S
+            {
+                for (int i = 0; i < this.sfComboBox.DropDownListView.CheckedItems.Count; i++)
+                {
+                    if ((this.sfComboBox.DropDownListView.CheckedItems[i] as Details).IsEnabled == false)
+                    this.sfComboBox.DropDownListView.CheckedItems.RemoveAt(i);
+                }   
+            }
+        }
+
+    private void DropDownListView_ItemChecking(object sender, Syncfusion.WinForms.ListView.Events.ItemCheckingEventArgs e)
+    {
+        bool isItemEnable = (this.sfComboBox.ComboBoxMode == ComboBoxMode.MultiSelection && this.sfComboBox.AllowSelectAll && e.ItemIndex == 0) ? true : (e.ItemData as Details).IsEnabled;
+        if (!isItemEnable)
+        e.Cancel = true;
+    }
+
+    private void DropDownListView_SelectionChanging(object sender, Syncfusion.WinForms.ListView.Events.ItemSelectionChangingEventArgs e)
+    {
+        if (e.AddedItems.Count > 0 && !(e.AddedItems[0] as Details).IsEnabled && e.AddedItems.Count != this.sfComboBox.DropDownListView.View.Items.Count)
+        e.Cancel = true;
+    }
