I am attempting to recreate an ArcMAP application we have by using the ArcGIS Viewer for Silverlight 3.2. Our map had several (15) custom tools designed to Select By Attribute on various layers in the map. Several of these tools might search the same layer but on different fields. Now in the Silverlight Builder, I can add the Query Tool multiple times and configure it to search several different layers. I have also had it search the same layer on different fields but it always seems to lose those tools when I save and close the Builder and open the site to test it. I had 10 tools set up in 2 Grouped Toolbars containing tools to search our Sewer features and our Parcels and such. I saved several times during the process and all of the tools were working when I last saved and published the site. When I opened it for testing there were only 2 tools in the Sewer Tools group and none in the Parcel Tools group on the main toolbar. I have lost all of my work and now when I try to recreate the tools again and save and publish after each one is added they are missing when I open the site in for editing or for testing. The tools are simply gone rom the toolbar even though the builder showed that the Changes Saved successfully.
Is there some limit on the number of Query Tools you can use in an application? What about using 2 or more Query Tools to search the same layer on different fields?
