This is not something I have had to deal with too often which is why it wasn’t apparent to me the first time around.
FACT: You cannot drag and drop a custom control or any System.Windows.Form.Control onto a System.Windows.Form.StatusStrip or System.Windows.Form.ToolStrip.
Aha! A gotcha! So how do you fix this problem? Well there are two options:
1. Make your own StatusStrip or ToolStrip item by inheriting from the System.Windows.Forms.ToolStripControlHost class.
Personally I don’t like this method because it forces you to make a control that is only good for this purpose.
You can read more about it here.
Frankly I find the name of the article to be very misleading, you aren’t really wrapping anything, you are creating a new class that inherits from the ToolStripControlHost. That’s like saying making a custom control is a wrapper because it inherits from the Control class. Not so much…
2. Use this handy dandy methodology that apparently has been there all along, but I didn’t find out about it until I stumbled across it yesterday during my google search. You simply need to add your custom control programmatically to your ToolStrip or StatusStrip by adding it as a ToolStripControlHost object.
You simply do the following:
Dim myControl As SomeCustomControl = New SomeCustomControl() 'Perform operations on your control such as size, color, minimum size etc... ToolStrip1.Items.Add(New ToolStripControlHost(myControl)) 'and/or StatusStrip1.Items.Add(New ToolStripControlHost(myControl)) 'If you are working with visbility, you will have to apply it to the ToolStripControlHost as well otherwise your control may not behave.
For the record I got all my info from this post here.
Please note there are sizing issues with this method and I haven’t figured them all out yet. So this will require more research to figure out. If and when I figure it out I will be sure to mention it. Just make sure to set the size and the minimum size properties.
I prefer the second option over the first, but there is nothing wrong with the first either. I think that you get more re-usability out of the second option.
