I'm using a ModalPopupExtender in my website, to show "accept/cancel" messages, and catch the user selection at the server side. I put two buttons (ok/cancel) at the panel that will be shown as a modal popup, add them a server side event handler, but it does not fire.

I want to handle asynchronous post back timeout error (Sys.WebForms.PageRequestManagerTimeoutException) on server side.
I use AsyncPostBackError event of ScriptManager class for other errors (exceptions) during asynchronous post back and it works fine. There is a response redirect to generic error page in this event handler.
Unfortunately for PageRequestManagerTimeoutException this event is not fired.
So how can I handle this error on server side?
scriptMgr.AsyncPostBackTimeout = 180;scriptMgr.AsyncPostBackError += new EventHandler<AsyncPostBackErrorEventArgs>(scriptMgr_AsyncPostBackError);...private void scriptMgr_AsyncPostBackError(object sender, AsyncPostBackErrorEventArgs e){Response.Redirect("~/System/GenericError.aspx");}
I have a panel extended by the ModalPopupExtender that is sometimes shown using the .Show() method in my code-behind. I have a javascript function that resizes the popup and am able to get it to run when I use the client-side show function but how do I run the same javascript function when using the server-side Show() function?
View 3 RepliesI'm using asp.net and c# to build a web application. I'm trying to display a popup message using the ModalPopup extender. The message displays fine only if it sets in client side or in server side but inside Page_Load. Otherwise, it displays as empty. the popup comes up without the message.
The thing is that i want to change the meesages when i call its show() method.
client side:
<asp:Panel ID="pnlMsg" runat="server" CssClass="modalPopup">
<asp:Label ID="lblModalMsg" runat="server" ></asp:Label>
<asp:Button ID="btnOk" runat="server" Text="OK" />
</asp:Panel>
<asp:ModalPopupExtender ID="ModalPopupExtender1" runat="server" TargetControlID="hidForModel"

View 10 RepliesI have a scenario where i have 4 asp buttons , on click of each button there are 4 labels inside 4 seperate divs where each displays seperate data.
Now if i click second button i need to display second label text inside 2nd div and hide all other divs.How can i achieve this ?
OnClientClick event of each button calls displayAlternate() which displays repective div and hides other.
displayAlternate('second'); return false; --> if i do this server side event is not fired ...
If I return true div second label is not getting displayed..
How can I achieve functionality where all divs expect 2nd is hidden and i get server side event also..

How can I raise a server-side event while I'm typing in it?
M - RI have a page like that and the control structure is like that.
UpdatePanel
Button
ModalPopupExtender
ModalPopup Content Container
Initially, ModalPopup Content Container is an empty control.After user clicks on the Button, a async postback will be triggered. During the postback, the server generates the content and appends to ModalPopup Content Container.Also sets the properties of ModalPopupExtender. Finally, calls ModalPopupExtender.Show() method and UpdatePanel.Update() method to show the modal popup.
This method works fine if all controls in ModalPopup Content Container contains simple control. If a control is a button that needs to postback to server side, that is a problem.Since the controls in ModalPopup Content Container is dynamically created. If a control in ModalPopup Content Container triggers a postback event, the control must be created before RaisePostBackEvent is called in server side.
My idea is to determine whether the ModalPopupExtender is hidden or shown in client side in order to re-generate the dynamic control in ModalPopup Content Container.So my question is how to determine a ModalPopupExtender is hidden or shown.
I have a ListView that contains a large collection of rows with textboxes that users can optionally fill out. These textboxes are not databound. When the user clicks "next" i need to iterate over the rows and determine which fields the user has filled out, and then update a sort of "cart" with the data and move to a confirmation page ("you have selected a, g, v, zz, is this correct?" sort of thing).
I can think of two ways to deal with this. The first is, server side, to walk the items in the listview, get the control ID's, save this data to a list, then save it to a database cart table for the next screen to read.I can use jquery to collect all the values client side, then pass it back to the form in a hidden field and use something like Newton.Json to get the data into a similar list.What are the tradoffs of these two approaches?
I need the user to be able to upload multiple files to my server, thus I am using the SWFUpload utility. SWFUpload sends the files one by one, and I need to store them all in the same temporary directory. My ASP.NET handler recieves the files one by one and I can store the file appropriately.
My problem is: How do I know which files belong to the same upload? Rephrased, how do I connect the files in my handler?
I have a print button and I want to trigger the modalpopupextender and trigger the server side Button1_Click Sub.The print button calls a function that constructs a html table with the values of the gridview selected row.How can I open the modalpopupextender and trigger the server side function at the same time with the same button?
View 2 RepliesI have developed a web application which contains aspdotnet treeview control. In this treeview control has binded with some database value.. that controls has one parent node and more than one child nodes for each parent node.
my problem is here, when the user clicks the parent node, I need to fire a javascript onclick function before the server side event(SelectedNodeChanged) called..
If I provide javascript to the parnet node when it is binding, then I could not fire the server side event(SelectedNodeChanged).
How to provide onclick javascript event for parent node in treeview control even the parent node has SelectedNodeChanged event.
I'm using what I believe is a pretty common/boring/generic implementation of a ModalPopupExtender. I'm using client-side JS to show the dialog when the user clicks a link, and hide it if they click "cancel". I only do a postback if they truly want to save the data.
I can click the link to show the dialog, then click the cancel button to hide it, then click the link to show it... ad infinitum. If I decide to save the data via a postback, everything works well, and the dialog is hidden as a result of the postback, all as expected.
However, once the postback completes, my client-side JS show() never works again. Any attempts to click the link fail quietly; no error messages, the dialog just never shows again.
I have created dynamic control with both server and client side events.. if i set client side event server side event is not firing.. I have created the link button which will validate and do some necessary actions.. Validation is working but click event of link button is not firing .. if we remove the client side event , server side event is firing.. how to avoid this.. I want both events..

like to ask how to stop triggering event Timer_Tick when ModalPopup is already shown. I use the following code:

I'd like after 15 seconds the ModalPopup to show, but the timer go on counting and triggering Timer1_Tick event. This operation should happen on user basis. So, if one user ModalPopup shows and stops Timer1_Tick event, for another user on the website, the Timer1_Tick should work.

How can I fire a ModalPopupExtender on the SelectIndexChanged event of a dropdownlist?
I only want it to fire when a particular value is chosen in the list.
I tried leaving the PopupControlID value out and calling .Show() on my extender in the onselectchanged event, but it would not allow me to have a blank PopupControlID. If I set the PopupControlID to the ID of my dropdownlist, the popup fires as soon as I click on the dropdownlist control.
Here is what I'm trying to do: Click a button on my page, which in turn makes (2) things happen:Display a ModalPopup to prevent the user from pressing any buttons or changing valuesCall my code behind method, hiding the ModalPopup when finished Here is the ASP markup:
