如何将ToolStripSplitButton添加到Visual Studio Toolbox？

Question

I am using Visual Studio 2010, and I have come across a need to use the ToolStripSplitButton button. I figured out from the reference material that ToolStripSplitButton is a form found under the System.Windows.Forms.

When I attempt to add this to my toolbox to try to use, I am unable to find ToolStripSplitButton, does anybody know how I can add this to my Visual Studio 2010 so I can use it? I don't care if it's not in the toolbox, I just want to make sure the assembly reference is present so I can actually use it.

Answer 1

It's inherited from and dependent on ToolStripDropDown so you can't use it as a stand-alone control. You can use it as a child control for ToolStripDropDown.

Answer 2

ToolStripSplitButton can be used only as ToolStripItem of a ToolStrip (contained in ToolStrip.Items ). It's designed so that you can't use it as a normal control. It doesn't have a Parent property, and I guess it also doesn't have a Handle property. The inheritance tree is:

ToolStripSplitButton
   -> ToolStripDropDownItem
       -> ToolStripItem
          -> Component
             -> ...

Normally, you have to add some ToolStrip to host ToolStripSplitButton .

If you want to use code, here is a simple example:

ToolStrip toolStrip1 = new ToolStrip();
ToolStripSplitButton splitButton1 = new ToolStripSplitButton("Hi there"){Owner = toolStrip1};
//you can add items to ToolStripSplitButton via ToolStripSplitButton.DropDownItems
