C# excel addin - Accessing Controls

问题

I am working on an addin for excel 2010 using C#. I have an existing worksheet that has some controls in it, namely a ComboBox. I am trying to write some code that will place a certain value in the combo box's text property, but I am having a hard time getting access to the control to do so.

The combo box is named 'ComboBox1' but if I try something like...

var combo = Controls["ComboBox1"];

I get an ArgumentOutOfRangeException.

Exploratory approaches to finding out what I am supposed to be doing aren't really providing useful information either. For example, if were to write;

MessageBox.Show(Controls[0].GetType())

The displayed message is 'NamedRangeImpl' which doesn't seem like a control at all. So my question is, how do I get access to the controls that are on my worksheet from my code?

回答1:

I'm not exactly sure about the problem but I've made addins for word and if its like windows forms this should work nicely.

foreach (Control c in Controls) 
   if (c.Name == "comboBox1") {
      ComboBox box = (ComboBox)c;
      box.Items.Add("Thing added");
   }
