How can I show an AJAX modal popup based on some code logic and NOT based on a button to be clicked? For example:
if (!User.Identity.IsAuthenticated)
{
Show a modal popup here which says: 'This process is only available to users who are logged into the system.'
}

View 5 RepliesIn my application, I have one Gridview on click button of one of the column I show Modal popup Extender. In Popup window I display another GridView with paging. And also I want to do operations such as Update, Delete and Add. As all these are Link buttons none of the event associated with them are firing.
Is there any way to execute server side events on Modal Popup Extender.

I copied the code from this tutorial:
[URL] into a page in a test project.
The problem is that when i push the client side button, it shows the popup and immediately refreshes (reseting to initial state of course).
Why is this happening in my new web project, but in that tutorial's demo doesn't?
I'm using IE7, FF3.5, VS2008, latest Ajax Control Toolkit.
I'm not sure if this is an easy issue to solve, but I can't seem to figure it out. I have a ModalPopupExtender (obviously) for a panel that contains a two labels, two textboxes, and two buttons (Ok and Cancel). What I would like to do is when the Ok button is clicked, the page post back and the server click event execute (along with normal page events). When I try adding "__doPostBack("ModalOk", "");" as the OnOkScript, the page posts back, but the click event doesn't execute. (the click event is Protected Sub ModalOk_Click(blah blah) Handles ModalOk.Click).
The only way I got it to work (which is fine with me, I just thought I'd ask why it isn't working normally) is by checking to see if the Request.Form("__EVENTTARGET") is equal to "ModalOk". If it is, then I call the ModalOk_Click() sub. Like I said, this is fine with me, but it should be able to be avoided. If the __EVENTTARGET is equal to "ModalOk", then the "Handles ModalOk.Click" event should automatically be called, shouldn't it? Following with the general problem here, how does the server determine which events (other than the page events) to execute (or at least which button.click event)? I understand that the __EVENTTARGET supplies what causes the postback, but if a button is clicked then __EVENTTARGET is not set. So then does the page check the Request.Form for a button? Or is it more complex/simple than what I'm asking?
Lets say I have a user control AjaxUC.
<asp:ModalPopupExtender ID="modalSearch" runat="server" TargetControlID="btnHiddenSearch"
PopupControlID="pnlModalSearch" DropShadow="false" RepositionMode="RepositionOnWindowResize"
Drag="false" BackgroundCssClass="modalBackground" >
</asp:ModalPopupExtender>
<asp:Button ID="btnHiddenSearch" runat="server" Style="display: none" />
<asp:Panel ID="pnlModalSearch" runat="server" CssClass="modalPopup">
<asp:Panel ID="pnlModalSearchContent" runat="server">
<asp:Label ID="lblSearchTitle" runat="server" CssClass="modalPopupTitle"></asp:Label>
<div id="divContent" runat="server">
</div>
<asp:Button ID="btnModalSearchClose" runat="server" Text="Close" CausesValidation="false"
OnClick="BtnModalSearchCloseClick" />
</asp:Panel>
</asp:Panel>
<input type="hidden" id="hdVisible" runat="server" />
------------------------------------------------------------------------ AjaxUC.ascx.cs:-
public partial class AjaxUC : System.Web.UI.UserControl { private ITemplate _content = null; [TemplateInstance(TemplateInstance.Single)] [TemplateContainer(typeof(Container))] [PersistenceMode(PersistenceMode.InnerProperty)] public ITemplate Content { get
{ return _content; } set
{ _content = value; } } void Page_Init() { if (_content != null) { Container container = new Container(); _content.InstantiateIn(container); divContent.Controls.Add(container); lblSearchTitle.Text = LblModalSearchText; } } protected void Page_Load(object sender, EventArgs e) { if (hdVisible.Value=="true") { modalSearch.Show(); } } } public class Container : Control, INamingContainer { internal Container() { } }}
This control when used on any aspx page will popup the control placed inside the template "divContent" as modalpopup.

Now I am trying to convert this user control to Custom Control and my code is:-

{ if (_pnlModalSearchContent == null) { _pnlModalSearchContent = new Panel(); } return _pnlModalSearchContent; } } public ModalPopupExtender ModalSearch { get
{ if (_modalSearch == null) { _modalSearch = new ModalPopupExtender(); } return _modalSearch; } } public string ViewState { get
{ return _viewState; } set
{ _viewState = value; } } public HtmlInputHidden HdVisible { get
{ if (_hdVisible == null) { _hdVisible = new HtmlInputHidden(); } return _hdVisible; } } [TemplateInstance(TemplateInstance.Single)] [TemplateContainer(typeof(DivContainer))] [PersistenceMode(PersistenceMode.InnerProperty)] public ITemplate Content { get

I am looking for sample code where a button click on the server side will spawn a modal child page, having couple of controls such as textboxes and a button, where one could enter values in the text boxes and click the button; once the button is clicked, the page should postback to the parent page, where the entered values could be read. There is a video on this site about AJAX control kits describing modal popup, but unfortunately it wouldn't serve my purpose.

in a form i have a buttoin, when click both OnclientClick and postback should happen. on clicking the "Email" button a client side "mailto" tag should do the work and pull a new message window on the client's machine.
whereas, the email addresses should be invoked by the post back. so , when clicking the button the server side post should happen and on return the client side script should be invokded with the values read during post back, and populate all the email addresses.
i need know how to first do a server hit take the values and then execute the client script with those values without using AJAX
I've got a gridview/formview, master/detail relationship going on. When I click a button in my formview (item template), I display an ajaxcontroltoolkit modal popup.
On this popup there is a textbox (several, actually). I want to validate the data in this textbox (at least six digits, so far I'm using a regex validator) before I dismiss the popup.
The validator works, but I can still dismiss the form by clicking OK. What I'd like to do is have the ok button on the popup disabled until the data is good.
I have tried fiddling with some stuff in javascript, but I couldn't make it work, as there seems to be some issues regarding finding controls in a formview.
