You can populate a dropdown via two different methods either by hydrating the DropDownItems collection or assigning a created ContextMenuStrip to the ToolStripDropDownItems DropDown property. Another handy feature of ToolStripDropDownItem is the DropDownItemClicked event. This allows you a handy way to not have to sync each item in a ToolStrip DropDowns click event. And you dont have to fish into the collection either, we just hand you back the item that was clicked on. The following sample shows these concepts.

 

// populate the DropDownItems Collection

ToolStripMenuItem veggiesMenuItem = new ToolStripMenuItem("Veggies");

veggiesMenuItem.DropDownItems.Add("Asparagus");

veggiesMenuItem.DropDownItems.Add("Bok Choy");

veggiesMenuItem.DropDownItems.Add("Cauliflower");

// Hook up the handler

veggiesMenuItem.DropDownItemClicked += new ToolStripItemClickedEventHandler(myDropDownItemClicked);

 

// assign a dropdown

ContextMenuStrip cms = new ContextMenuStrip();

cms.Items.Add("Apples");

cms.Items.Add("Bananas");

cms.Items.Add("Cherries");

 

ToolStripMenuItem fruitMenuItem = new ToolStripMenuItem("Fruit");

fruitMenuItem.DropDown = cms;

// Hook up the handler

fruitMenuItem.DropDownItemClicked += new ToolStripItemClickedEventHandler(myDropDownItemClicked);

 

// menustrip

MenuStrip ms = new MenuStrip();

ms.Items.Add(fruitMenuItem);

ms.Items.Add(veggiesMenuItem);

this.Controls.Add(ms);

When should I use Paint/OnPaint and when should I override the ToolStripRenderer?
Do I need to worry about double buffering?
