  Has no one else run into this problem? I was really hoping to use the ListSearchExtender in this manner. Thanks, Nick

• ListSearchExtender causing Sys.InvalidOperationException

  Hello all, I am having an issue with ListSearchExtender. I have the ListSearchExtender inside of an Panel, which is inside of an UpdatPanel. There is a CheckBox on the form, that when clicks, causes the Panel to become visible. When I select the CheckBox, the Panel shows up just fine an everything works. When I do anything that causes a postback after this is done, I get the following javascript error: Sys.InvalidOperationException: Handler was not added through the Sys.UI.DomEvent.addHandler method

• Re: Value Checking In A ModalPopup -- Preventing From Close/Hide

  Without seeing the code, I can't say for sure, but if you are using say a button as the Ok or Cancel Control of the Modal Popup, what you could do is put that button inside of an UpdatePanel. Then define the button's Click event in code behind. In the code behind get the ModalPoupExtender and call it's Close() method. Make sure that you do not set the Ok or Cancel control of the Modal Popup. Is this what you are trying to do?

• Re: Sys.InvalidOperationException: Handler was not added through the Sys.UI.DomEvent.addHandler method after upgrading to RC1

  We too were having this same problem. I have finally found a workaround. The issue is caused when the Ok and/or Cancel Buttons of the ModalPopupExtender are defined within the UpdatePanel of the Panel that is popped up. To fix the problem with the code provided, do the following: Change this line: < ajax:ModalPopupExtender ID= "ModalPopupExtender" runat= "server" TargetControlID= "InvisButton" PopupControlID= "ResourceGalleryPanel" BackgroundCssClass= "GalleryBackground" DropShadow= "true" OkControlID

• Re: Problem with ValidatorCalloutExtender

  I have not been able to get the ValidatorCalloutExtender to work inside of an updatpanel. Which is unfortunate, because the control I'm validating has to be inside of an updatepanel.

• Re: RegisterDataItem can only be called during an async postback

  I get this error message when I attempt to call the PopupExtender's Commit function from a Button's Click event. It does not give this error message when called from a Calendar's SelectedItemChanged event. I have written two user controls, one that has a Button which is to apply the results of the popup control to my textbox, and one that uses a calendar to apply the results to the textbox. The funny thing is, I have an imagebutton on the calendar control, to cancel the popup. It also throws the

• Re: AutoCompleteExtender with "asp" tag prefix?

  Try putting the following in your web.config file: <controls> <add tagPrefix="asp" namespace="Microsoft.Web.Preview.UI" assembly="Microsoft.Web.Preview"/> <add tagPrefix="asp" namespace="Microsoft.Web.Preview.UI.Controls" assembly="Microsoft.Web.Preview"/> </controls> You'll have to remove the Register from your page, and then you can change your cc1 to asp on your page. One thing to note, if you are using a master page, visual studio will start showing errors on ALL asp controls

• PopupControlExtender Cancel not working

  I have written a UserControl that contains a PopupControlExtender for selection of a date. This control also contains an imagebutton, which when clicked, is supposed to cancel the popup. This is not working, when the ImageButton is clicked, the Popup does not go away. Below is the .ascx page: <%@ Control Language="C#" AutoEventWireup="true" CodeFile="DatePicker.ascx.cs" Inherits="User_Controls_DatePicker" %> <aspAjax:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">

• Re: How to post back without really posting back?

  Well, you could make sure that the control you want to update server-side is in an update panel. Then put a button in that update panel, and call it's click event from your javascript. This will cause and Asyncpostback and the only thing that will update is the content inside of your updatepanel.
