The classes named below can refer either to MaestroAPI classes or Xml
tag names.
The code given is for the MaestroAPI.
There is no equivalent for the official API, and you will have to do
this using Xml
manipulation.
Search for a file called LayerDefinition-1.2.0.xsd for a description of
such a document.

Files\MapGuideOpenSource2.0\Server\Schema\LayerDefinition-1.2.0.xsd

I have shown that in the sample code.
3)
I have included code?

Hi,
Thanks for u r reply.But i didnt find PointRuleType anywhere?
1) where can i find this?
2) And how to apply properties to the layer?
3) can u send me the code.
so that it will be very helpful.
Thanks and Regards,

I don't know where or what the LayerDefinitionFactory is, but to add
thematic rules
you simply add a "PointRuleType", "LineRuleType" or "AreaRuleType" to the
"PointTypeStyleType", "LineTypeStyleType" or "AreaTypeStyleType"
collection of the
desired scalerange.
eg:
PointRuleType prt = new PointRuleType();
prt.Filter = "\"ID\" > 100";
//TODO: Set style and other properties
LayerDefinition ldef; //<-- Assign this
VectorLayerDefintionType vldef = ldef.Item as VectorLayerDefinitionType;
//If you have more than just points, you must itterate the "Items" to
find the right one
PointTypeStyleType pst = vldef.VectorScaleRange[0].Items[0] as
PointTypeStyleType;
pst.PointRule.Add(prt);

Hi there,
There is no .NET equivalent to LayerDefintionFactory. You'll have to
port
it over to .net.
layerdefinitionfactory.php simply takes a bunch of xml templates in the
"viewerfiles" directory of your web extensions install folder and fills
in the blanks with the parameters you provide.
example of CreateAreaRule() in .net:
class LayerDefinitionFactory
{
...
public static string CreateAreaRule(string legendLabel, string
filterText, string foreGroudColor)
{
StreamReader reader = new
StreamReader("path/to/arearule.templ");
string areaRuleXml = reader.ReadToEnd();
string [] values = new string[] { legendLabel, filterText,
foreGroundColor };
areaRuleXml = Substitute(areaRuleXml, values);
return areaRuleXml;
}
...
static String Substitute(String templ, String[] vals)
{
StringBuilder res = new StringBuilder();
int index = 0, val = 0;
bool found;
do
{
found = false;
int i = templ.IndexOf('%', index);
if(i != -1)
{
found = true;
res.Append(templ.Substring(index, i - index));
if(i < templ.Length - 1)
{
if(templ[i+1] == '%')
res.Append('%');
else if(templ[i+1] == 's')
res.Append(vals[val ++]);
else
res.Append('@'); //add a character illegal
in
jscript so we know the template was incorrect
index = i + 2;
}
}
} while(found);
res.Append(templ.Substring(index));
return res.ToString();
}
}
Other CreateXXX functions are variations on the above example.
