C# PropertyGrid
各位大侠，最近在用PropertyGrid做项目，遇到一个问题:PropertyGrid控件进行分组后，复合类型的属性，例如“字体”类型的属性，在归类后，如何让它左边有缩进呢？像下图那样？
ColorProperty m_cp;
public ColorProperty 颜色
{
get
{
if (m_cp == null)
m_cp = new ColorProperty("0x000000");
return m_cp;
}
set { m_cp = value; }
}
[TypeConverter(typeof(ColorPropertyConverter))]
public class ColorProperty
{
string colorstr = "0x000000";
public string 颜色值
{
get
{
if (colorstr.Length != 8)
colorstr = "0x000000";
return colorstr;
}
set
{
if(value.Length==8)
colorstr = value;
}
}
public Color 颜色
{
get { return UInt32ToColor(colorstr); }
set { colorstr = ColorToUInt32(value);}
}
public ColorProperty(string str)
{
colorstr = str;
}
public ColorProperty(Color color)
{
颜色 = color;
}
public string ReturnColorStr()
{
return colorstr;
}
public string ColorToUInt32(Color color)
{
string r = Convert.ToString(color.R, 16);
if (r.Length == 1) r = "0" + r;
string g = Convert.ToString(color.G, 16);
if (g.Length == 1) g = "0" + g;
string b = Convert.ToString(color.B, 16);
if (b.Length == 1) b = "0" + b;
return "0x" + (r + g + b).ToLower();
}
public Color UInt32ToColor(string aa)
{
string A = "ff";
string R = aa.Substring(2, 2);
string G = aa.Substring(4, 2);
string B = aa.Substring(6, 2);
return Color.FromArgb(Convert.ToInt32(A, 16), Convert.ToInt32(R, 16), Convert.ToInt32(G, 16), Convert.ToInt32(B, 16));
}
}
public class ColorPropertyConverter : ExpandableObjectConverter
{
public override bool CanConvertTo(ITypeDescriptorContext context, System.Type destinationType)
{
if (destinationType == typeof(ColorProperty))
return true;
return base.CanConvertTo(context, destinationType);
}
public override object ConvertTo(ITypeDescriptorContext context, CultureInfo culture, object value, System.Type destinationType)
{
if (destinationType == typeof(System.String) && value is ColorProperty)
{
ColorProperty so = (ColorProperty)value;
return so.颜色值;
}
return base.ConvertTo(context, culture, value, destinationType);
}
public override bool CanConvertFrom(ITypeDescriptorContext context, System.Type sourceType)
{
if (sourceType == typeof(string))
return true;
return base.CanConvertFrom(context, sourceType);
}
public override object ConvertFrom(ITypeDescriptorContext context, CultureInfo culture, object value)
{
if (value is string)
{
try
{
ColorProperty so = new ColorProperty((string)value);
return so;
}
catch
{
throw new ArgumentException("格式错误");
}
}
return base.ConvertFrom(context, culture, value);
}
}
