<br>Is that right?<br><br>And how about Mapfile configuration, Am I suppossed to change anything?

<div>Hi Arnd...<br>I have some questions about that...<br><br>First I have a geo
app using Openlayers/Mapserver WMS with SDE layers....<br>My application has a
treeview with all layers, and a radiobox for each layer... When I click in a
layer´s radiobox a window with a GRID containing all layer´s data is
opened...<br>In that GRID, When I select a line (layer´s data), the Map should
:<br> 1-) Highlight it <br> 2-) Zoom in data selected<br><br>Can I
develope that using SLD and SLD_BODY ? Do you have any tip to how do
that?<br><br>Thanks<span><font color="#0000ff" face="Arial" size="2"> </font></span></div></div></div>
