AJAX :: Modalpopupextender And Update Panel - Disable Controls?

Jan 25, 2010

I have a webpage that contains a ModalPopupExtender who's PopupControlID contains a panel wrapped in an update panel. The panel contains a RadioButtonList and I have subscribed to the SelectedIndexChanged event in which I am setting an OnClientClick event for a button also inside the panel and update panel. My problem is that when the postback fires the controls in the panel are still enabled, that is the user can click the button before it has had a chance to set the OnClientClick code. Other update panels on this page (unrelated to the ModalPopup) seem to disable to use of other controls while the postback is occurring. How can I make this work in my ModalPopupExtender?

Here is my code

I have a formview with an image and a panel which is initially hidden/invisible.

I want to make panel visible on mouseover event of the image and make it invisble on mouseout.

I tried to img.Attributes.Add("onmouseover", "showPanel()") in FormView1_ItemCreated ( object sender, EventArgs e) event.

AJAX :: ListView Inside Update Panel Does Not Show Updated Values

Jan 16, 2014

I have a ListView control that is inside of an update panel.  I have a Button control that calls code behind when clicked and I have a trigger in the update panel that is triggered based on the click event of the button.  The button that calls the code behind and inserts a record into the database works fine but I get a full page refresh and the ListView Data is not updated as expected.  I then can go to another page, come back and the new data is there.  I'm not sure what I missing.  Please see the code below.

<asp:UpdatePanel ID="UpdatePanel1" runat="server" >

<asp:ListView ID="ListView2" runat="server" DataSourceID="sdsrcMessageComments" DataKeyNames="MessageId"
ItemPlaceholderID="PlaceHolder2" EnableViewState="False">

Can Use Jquery To Show Or Hide Panel On Button Click

Feb 1, 2011

I have a panel at the top of my page which contains some cascading dropdown lists. Once the user selects from the lists, they will click a 'Search' asp.net button and a gridview will appear below showing the search results. What I want to do is use JQuery to toggle the visibility of the search panel. I tried using the Ajax collapsiblepanelextender but ran into all kinds of problems, because there are many updatepanels and ajax extension controls on this page. It sounds so simple, just hide or show, but I can't get it to work. When I click the button, the panel hides. When I click it again, the panel does not reappear. I have also tried having 2 buttons, 'hide' and 'show', and had the same results. right now here is my code:

$(document).ready(function() {
$("[id$=btnHideSearch]").click(function() {
$("#<%= Panel1.ClientID %>").fadeOut('slow');
$(document).ready(function() {
