PROJECT DESCRIPTION
This project shows how you can show a loading message while a large treeview data is being loaded on the page. Thus, the users will be aware that something is happening. This sample project does not use any ajax but a simple javascript approach:
| <script type="text/javascript"> |
| function pageLoad() |
| { |
| var treeDIV = document.getElementById("treeDIV"); |
| treeDIV.style.visibility = "visible"; |
| |
| var loadDIV = document.getElementById("loadDIV"); |
| loadDIV.style.visibility = "hidden"; |
| } |
| </script> |
| <div id="loadDIV"> |
| Loading Message |
| </div> |
| <div id="treeDIV" style="visibility:hidden"> |
| <telerik:RadTreeView ID="RadTreeView1" runat="server"> |
| </telerik:RadTreeView> |
| </div> |
| <div id="loadDIV"> |
| Loading Message |
| </div> |
| <div id="treeDIV" style="visibility:hidden"> |
| <radT:RadTreeView |
| ID="RadTree1" |
| Runat="server" ... /> |
| <script type="text/javascript"> |
| window.onload = function() |
| { |
| var treeDIV = document.getElementById("treeDIV"); |
| treeDIV.style.visibility = "visible"; |
| |
| var loadDIV = document.getElementById("loadDIV"); |
| loadDIV.style.visibility = "hidden"; |
| } |
| </script> |
