We are enhancing a web page that serves up a graphical chart. To serve this chart we have various filters on the page that the user can use to indicate the content they wish to retrieve. After getting too much clutter on the page we decided we would move the filters into a modalpopup panel that the Ajax Toolkit provides. To divide the filters by topic we placed a TabContainer with several TabPanels inside the modal panel. One of our filters indicates the minimum and maximum range of values to display. The MultiHandleSlider extender is perfect for this task. This control works if we place it on the web page, inside the modal panel, but not if we place it inside a TabPanel. It appears to be generating javascript errors that prevent the page from rendering properly if it is inside a TabPanel.
Does anyone know of a workaround for this or what we should be looking at to correct this? We are using the ToolkitScriptManager on the page and we are using the 40412 build of the Ajax Control Toolkit.
