我已经定制了一个TabPage,但发现存在以下问题:
首先,我创建两个自定义TabPage,它工作。
但是当我关闭文档然后我重新打开文档时出现问题:
看,TabPage变为四,但我在“designer.cs”文档中找到了问题。
//
// blK_TabControl1
//
this.blK_TabControl1.Controls.Add(this.blK_TabPage6);
this.blK_TabControl1.Controls.Add(this.blK_TabPage7);
this.blK_TabControl1.Location = new System.Drawing.Point(4, 12);
this.blK_TabControl1.Name = "blK_TabControl1";
this.blK_TabControl1.SelectedIndex = 0;
this.blK_TabControl1.Size = new System.Drawing.Size(604, 196);
this.blK_TabControl1.TabIndex = 14;
this.blK_TabControl1.TabPages.AddRange(new System.Windows.Forms.TabPage[] {
this.blK_TabPage6,
this.blK_TabPage7});
正常的TabControl添加TabPage后,没有“TabPages.AddRange()”这段代码,我该如何解决?
这是我的代码:
public class BLK_TabPageCollectionEditor : CollectionEditor
{
public BLK_TabPageCollectionEditor(Type type)
: base(type)
{
}
protected override bool CanSelectMultipleInstances()
{
return false;
}
protected override Type CreateCollectionItemType()
{
return typeof(BLK_TabPage);
}
protected override object CreateInstance(Type itemType)
{
BLK_TabPage tabPage = (BLK_TabPage)itemType.Assembly.CreateInstance(itemType.FullName);
IDesignerHost host = (IDesignerHost)this.GetService(typeof(IDesignerHost));
host.Container.Add(tabPage);
//this.Context.Container.Add(tabPage);
tabPage.Text = tabPage.Name;
return tabPage;
}
}
public class BLK_TabControl : TabControl
{
[EditorAttribute(typeof(BLK_TabPageCollectionEditor), typeof(UITypeEditor))]
[MergableProperty(false)]
public new TabControl.TabPageCollection TabPages
{
get
{
return base.TabPages;
}
}
}
提前致谢。

我已经尝试过您的代码了。看起来一切都很好。但基于设计器生成的代码和图像描述,我唯一可以建议的是隐藏TabPages
属性的序列化:
[DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
[EditorAttribute(typeof(BLK_TabPageCollectionEditor), typeof(UITypeEditor))]
[MergableProperty(false)]
public new TabControl.TabPageCollection TabPages
{
get
{
return base.TabPages;
}
}
