我有一个实现自定义ToolStripItem的类。在设计时尝试将项目添加到ContextMenuStrip之前,似乎一切都很顺利。如果我尝试直接从ContextMenuStrip添加自定义控件,则PropertyGrid会冻结并且不会让我修改Checked或Text属性。但是如果我进入ContextMenuStrip PropertyGrid并通过Items(...)
属性添加我的自定义控件,我可以在该对话框中很好地修改自定义控件。我不确定如果我在某个地方遗漏了某个属性,如果它存在底层代码的问题。这里是CustomToolStripItem类的一个副本。正如你所看到的,它是一个非常简单的课程。自定义控件与PropertyGrid不兼容
[ToolStripItemDesignerAvailability(ToolStripItemDesignerAvailability.ContextMenuStrip)]
public class CustomToolStripItem : ToolStripControlHost {
#region Public Properties
[Description("Gets or sets a value indicating whether the object is in the checked state")]
[ReadOnly(false)]
public bool Checked { get { return checkBox.Checked; } set { checkBox.Checked = value; } }
[Description("Gets or sets the object's text")]
[ReadOnly(false)]
public override string Text { get { return checkBox.Text; } set { checkBox.Text = value; } }
#endregion Public Properties
#region Public Events
public event EventHandler CheckedChanged;
#endregion Public Events
#region Constructors
public CustomToolStripItem()
: base(new FlowLayoutPanel()) {
// Setup the FlowLayoutPanel.
controlPanel = (FlowLayoutPanel)base.Control;
controlPanel.BackColor = Color.Transparent;
// Add the child controls.
checkBox.AutoSize = true;
controlPanel.Controls.Add(checkBox);
}
#endregion Constructors
#region Protected Methods
protected override void OnSubscribeControlEvents(Control control) {
base.OnSubscribeControlEvents(control);
checkBox.CheckedChanged += new EventHandler(CheckChanged);
}
protected override void OnUnsubscribeControlEvents(Control control) {
base.OnUnsubscribeControlEvents(control);
checkBox.CheckedChanged -= new EventHandler(CheckChanged);
}
#endregion Protected Methods
#region Private Methods
private void CheckChanged(object sender, EventArgs e) {
// Throw the CustomToolStripItem's CheckedChanged event
EventHandler handler = CheckedChanged;
if (handler != null) { handler(sender, e); }
}
#endregion Private Methods
#region Private Fields
private FlowLayoutPanel controlPanel;
private CheckBox checkBox = new CheckBox();
#endregion Private Fields
这并不给我我的其他自定义控件给我的标准外观。我真的很想知道是否有'ToolStripControlHost'发生了一些古怪的事情,或者如果我在我的代码中丢失了某些东西。 – lumberjack4 2010-03-30 21:19:40
