Here is the text of my post:<br>
<snip><br>
</span></font><tt><font size=2 face="Courier New"><span style='font-size:10.0pt'>When
using the server API for altering layer visibility, a call to the </span></font></tt><font
size=2 face="Courier New"><span style='font-size:10.0pt;font-family:"Courier New"'><br>
<tt><font face="Courier New">GetMapFrame().Refresh() is not sufficient to
refresh the legend. </font></tt><br>
<br>
<tt><font face="Courier New">Pseudocode: </font></tt><br>
<tt><font face="Courier New">$map.Open(...); </font></tt><br>
<tt><font face="Courier New">$map.Layers('layername').setVisibility(true); </font></tt><br>
<tt><font face="Courier New">$map.Save(); </font></tt><br>
<br>
<tt><font face="Courier New">Calling the GetMapFrame().Refresh() after this,
will update the map to </font></tt><br>
<tt><font face="Courier New">display the new layer. </font></tt><br>
<tt><font face="Courier New">However the Legend does not reflect this change. </font></tt><br>
<br>
<tt><font face="Courier New">The problem can be solved with two changes: </font></tt><br>
<tt><font face="Courier New">1. In ajaxmappane.templ, the Refresh() function
should also call </font></tt><br>
<tt><font face="Courier New">ResetVisLayers() </font></tt><br>
<tt><font face="Courier New">2. In legendctrl.templ, the Refresh call should be
changed, so it does </font></tt><br>
<tt><font face="Courier New">not call with the summary parameter </font></tt><br>
<br>
<tt><font face="Courier New">The problem only occurs in the <st1:City w:st="on"><st1:place
w:st="on">AJAX</st1:place></st1:City> viewer. </font></tt><br>
<tt><font face="Courier New">When retrieving the legend script, using the
summary parameter, the </font></tt><br>
<tt><font face="Courier New">visibility does not change. </font></tt><br>
<tt><font face="Courier New">Removing the summary parameter is a bad fix, as it
also disables the </font></tt><br>
<tt><font face="Courier New">optimizations that the summary parameter gives. </font></tt><br>
<br>
<tt><font face="Courier New">If the above mentioned fix 1, is not implemented,
a lot of features will </font></tt><br>
<tt><font face="Courier New">fail after modifying the map. </font></tt><br>
<tt><font face="Courier New">For instance tooltips for the layers will not
work. </font></tt><br>
<br>
<tt><font face="Courier New">I think this is a problem with a design flaw in
the way the viewer is </font></tt><br>
<tt><font face="Courier New">implemented. </font></tt><br>
<tt><font face="Courier New">Keeping state data solely on the client is a very
bad idea. </font></tt><br>
<tt><font face="Courier New">This happens with layerstates and current zoom in
the <st1:City w:st="on"><st1:place w:st="on">AJAX</st1:place></st1:City>
viewer, and </font></tt><br>
<tt><font face="Courier New">the Selection in the DWF viewer. </font></tt><br>
<br>
<tt><font face="Courier New">To allow modifications to the map from the server
API, all data should </font></tt><br>
<tt><font face="Courier New">be written to the server. </font></tt><br>
<tt><font face="Courier New">To provide caching the client should fetch a
change list, rather than </font></tt><br>
<tt><font face="Courier New">sporadically caching data. </font></tt><br>
<tt><font face="Courier New">Using a sequence number, the client can skip
multiple update cycles, and </font></tt><br>
<tt><font face="Courier New">still be synced correctly. </font></tt><br>
<tt><font face="Courier New">Using a generic format would allow the DWF and <st1:City
w:st="on"><st1:place w:st="on">ajax</st1:place></st1:City> viewer to work on </font></tt><br>
<tt><font face="Courier New">exactly the same data, thus reducing duplicate
code. </font></tt></span></font><br>

functions must happen server side in this instance. But, it looks like
you could put your .NET conditional code in the gotopoint.aspx page and it
would work. The OnPageLoad() javascript function would fire afterwards so
all should behave smoothly. And, you would not have to programmatically
refresh the map since that will happen with the ZoomToView anyway.</span></font><O:P></O:P><u1:p></u1:p><o:p></o:p></p>
