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.
