先看个图
相信大家都很熟悉吧,我们可以用这个面板很方面的使用预定的样式.我们可以称之为自动格式设置或者自动套用样式.
ControlDesigner类提供了AutoFormats属性,其提供了DesignerAutoFormat类的DesignerAutoFormatCollection集合.我们来看下相关的类.
DesignerAutoFormat 是一个基类，如果你想为你的控件在设计时提供格式化的功能,你可以从此类派生,你必须实现Apply方法,此方法会将相关联的控件设置样式.由于实现比较简单就不再多多了,就直接拿MSDN的例子来看吧. 注意给 IndentLabelDesigner 加上SupportsPreviewControl元数据,这样可以支持预览功能.
[Designer(typeof(IndentLabelDesigner)),
ToolboxData("<{0}:IndentLabel Runat="server"></{0}:IndentLabel>")]
public class IndentLabel : Label
{
[SupportsPreviewControl(true)]
public class IndentLabelDesigner : LabelDesigner
{
private DesignerAutoFormatCollection _autoFormats = null;
public override DesignerAutoFormatCollection AutoFormats
{
get
{
if (_autoFormats == null)
{
_autoFormats = new DesignerAutoFormatCollection();
_autoFormats.Add(new IndentLabelAutoFormat("MyClassic"));
_autoFormats.Add(new IndentLabelAutoFormat("MyBright"));
_autoFormats.Add(new IndentLabelAutoFormat("Default"));
}
return _autoFormats;
}
}
}
private class IndentLabelAutoFormat : DesignerAutoFormat
{
public IndentLabelAutoFormat(string name)
: base(name)
{ }
public override void Apply(Control inLabel)
{
if (inLabel is IndentLabel)
{
IndentLabel ctl = (IndentLabel)inLabel;
if (this.Name == "MyClassic")
{
ctl.ForeColor = Color.Gray;
ctl.BackColor = Color.LightGray;
ctl.Font.Size = FontUnit.XSmall;
ctl.Font.Name = "Verdana,Geneva,Sans-Serif";
}
else if (this.Name == "MyBright")
{
this.Style.ForeColor = Color.Maroon;
this.Style.BackColor = Color.Yellow;
this.Style.Font.Size = FontUnit.Medium;
ctl.MergeStyle(this.Style);
}
else
{
ctl.ForeColor = Color.Black;
ctl.BackColor = Color.Empty;
ctl.Font.Size = FontUnit.XSmall;
}
}
}
}
}
这么着效果就实现了,这次比较懒,没好好写,还想打算写别的,就先这样吧
