I don't think you remove the previous layer from the MgMap?
Try setting the legend label to something obvious, and DisplayInLegend =
true,
so you can see if the layer is actually added to the map.
You may have to right click and choose Refresh in the legend for the
layer to appear.
As for the map.Save(), you need the mapname, like:
map.Save(resourceService, "Sheboygan");

}
else
{
lblerror.Text = "Please enter correct scale ranges.";
}
where i need to change please guide me.
thanks
