posted January 9, 2007 10:00 AM I have the following problems with the LiveCheckBoxList component: 1) if I add dinamically an Item to the list, the list is automatically updated only if it has altready some items in it; if it is empty it is not updated until page is reloaded. The code I use to add an Item is myList.Items.Add(new ListItem(itemName, itemValue)); 2) if a clear a list containing some items the list is not updated until I reload the page; my code is: myList.Items.Clear(); 3) if I select an item in the list the checkbox becomes automatically unchecked immediately after I check it with the mouse All these actions are performed inside LiveButton_Click event handlers and my version of PowerWeb LiveControls is 1.5.4 Thanks Sandro |

posted January 9, 2007 11:17 AM Hi Sandro, I am unable to reproduce any of your reported behavior. Here is the simple test I performed: //Two LiveButtons and a LiveCheckBoxList private void LiveButton1_Click(object sender, System.EventArgs e) { //Add items and check each selected state LiveCheckBoxList1.Items.Add(new ListItem(DateTime.Now.ToString(), DateTime.Now.ToString())); for (int i=0; i<LiveCheckBoxList1.Items.Count; i++ System.Diagnostics.Debug.WriteLine(LiveCheckBoxList1.Items[i].Value + ": " + LiveCheckBoxList1.Items[i].Selected.ToString()); System.Diagnostics.Debug.WriteLine(""); } private void LiveButton2_Click(object sender, System.EventArgs e) { //Clear items in list LiveCheckBoxList1.Items.Clear(); } Everything I tried worked as expected. Does this simple example work for you? What must be changed to see the behavior you describe? Thanks, -ken |

posted January 10, 2007 10:40 AM Hi Ken, I tried your example on my machine but it does not work: when I add an item to the list it is not shown in the browser if the list does not contain at least one static element. If the list is empty when I compile then I'm not able to see anything inside the browser even if I add items to the list; using a breakpoint I inspected the list and it contains all the items I added dinamically but they are not show on screen. |

posted January 10, 2007 12:26 PM Hi, What version of VS.NET are you using? What browser are you using? My app was developed with 2003, and I tried IE6, IE7 and Firefox. Thanks, -ken |

posted January 11, 2007 9:41 AM Hi Sandro, When I converted my 2003 project to 2005, it still worked, but then I tried a new 2005 project and saw the problem. This has been reported to development as issue #4229. To get the status of this issue, please contact David Harry (sales@dart.com). Thanks for your help with this, -ken |
