示例1: MyToolboxItem
// Toolbox items must be serializable.
[Serializable]
class MyToolboxItem : ToolboxItem
{
// The add components dialog in Visual Studio looks for a public
// constructor that takes a type.
public MyToolboxItem(Type toolType)
: base(toolType)
{
}
// And you must provide this special constructor for serialization.
// If you add additional data to MyToolboxItem that you
// want to serialize, you may override Deserialize and
// Serialize methods to add that data.
MyToolboxItem(SerializationInfo info, StreamingContext context)
{
Deserialize(info, context);
}
// Let's override the creation code and pop up a dialog.
protected override IComponent[] CreateComponentsCore(
System.ComponentModel.Design.IDesignerHost host,
System.Collections.IDictionary defaultValues)
{
// Get the string we want to fill in the custom
// user control. If the user cancels out of the dialog,
// return null or an empty array to signify that the
// tool creation was canceled.
using (ToolboxItemDialog d = new ToolboxItemDialog())
{
if (d.ShowDialog() == DialogResult.OK)
{
string text = d.CreationText;
IComponent[] comps =
base.CreateComponentsCore(host, defaultValues);
// comps will have a single component: our data type.
((UserControl1)comps[0]).LabelText = text;
return comps;
}
else
{
return null;
}
}
}
