AJAX :: Performace With UpdatePanel In ModalPopup Control?
May 20, 2010
I am using a modal popup control which contains an UpdatePanel. There are one combo and few text boxes and Calendar control in it. When I select any item in combobox, then it's selection change event is fired and there iI set the values of other controls and finally I call update method of update panel. Functionality wise it works properly but it takes a time to update the panel.Here combobox contains around five thousands of items. But when it contains 100s of items it works good.
A multiview with one View using a recaptcha and Modalpopup for response to a submit button within the ViewAn UpdatepanelI've spent hours and hours and hours searching around for any sort of solution that covers all of those without *some* sort of problem. If I put the menu inside, something won't work. If I put it outside, something else won't work. If I set 'conditional' or 'child-this-or-that' or whatever, *something* comes out to bite me. The recaptcha will vanish, or there are postbacks, or Modalpopup has gone agai
I have a databound listbox that is inside an update panel. When selecting an item in the listbox, I want it to populate labels in a panel that are displayed in a modalpopup. When I click on the listbox, I can see that the data is passed to the labels and the modal.Show() is executed by stepping through the code. However, the modalpopup comes up but with no data.
In my web application, i have declared modalpopup extender and corresponding div(popup control) inside master page to make it generic. In my page i am using updatepanel with a button inside it. Clicking on this button will fire the modalpopup extender. Before calling show() of modalpopup i am setting some text to a label inside the popup control. But when the popup comes, the updated text is not showing.
I have a simple form with a list of linkbuttons, each fires the same onclick event which sets an indicator image. I have a dummy button with style="display:none" which I have set as the TargetControlID of the modal.
onClick event from the imagebutton, the modal is shown via modal.Show(). The cancel button inside the modalpopup fires an event which turns off the indicator image and hides the modal via modal.Hide().
The events fire perfectly, it's very simple! Although after doing some testing I noticed the modalpopup is not presented after the 6-10th cycle of clicking the open event, then clicking cancel. The grey background appears but it is behind the main panel and the modal is either presented behind this or is just simply not displaying.
I spent hours researching various methods, implemented the CancelControlID to see if it was somehow tied to my call of modal.Hide() that fails.This occurs with an updatepanel only. The behaviour is much cleaner this way, so I would hope to be able to implement this. I have basically eliminated everything but these two events!
i have used modalpopupextender in my project .. in that i have dropdownlist .problem is that when i want to select any item from the list by arrow keys the control goes from modalpopup to vertical scrollbar of the main screen and whole screen get scrolling when i use up and down arrow key...
i don't want it , i want when i use up and down arrow key the control should be on the modalpopup..
I am quite new to asp.net. I would like to ask for some advice on how this scenario can be achieved. Here is the problem:
I have a 5 gridviews on my page. In each gridview, I have two important columns. They are SellerID and BuyerID. Because I already have too many gridviews on the page, I want to load a webuser control with a modalPopupExtender when either SellerID or BuyerID is clicked. That is to say if a user select a SellerID, the details information about that SellerID should be loaded with DetailView from the user control and if the buyerID is click, the details information about that buyer should be loaded with another detailview from the user control as well.
My problem is I do not know how to get the Selected Value from the gridView since the DetailView is in the WebUserControl. One more thing, both SellerID and BuyerID are in the same GridView, so how can we distinguish when a user select a SellerID or vice versa.
I have a flash on my page and I need to popup an ajax window, I use ModalPopupExtender. The problem is that ajax popup window always shows behind the flash in Internet explorer and Google Chrome. In firefox there are no such problem.
I have found a couple of good topics here in the forum and wanted to see any other extra ideas for this control that I am making and trying to implement. So here is the basic information:
The control is going to display a SQL output in a bunch of label controls. The information is going to be coming from a gridview control where the field is going to be hyperlinked.
So I am wanting to set the "TargetControlID" property to the .ascx page load event.
now what I have found is that I can simply run the Popup.show(); function in the .cs file at the end of the page load, but I still have to place a valid control within the TargetControlID property. As you know, the property cannot be "null" and if I put in the control ID for something that is not valid, then it won't work either. So the only thing I can think of is tying it back to the overall control itself. Then I can always change it on the fly if needed, but I think I would not have to since it would fire on the page_load event...
Not sure if this is making any sense... Just understand that have to make this control go across several web pages that are already fully developed. I am just adding this in as new functionality...
I have a page that has a few requirements1. A Gridview that is dynamically populated (and refreshed at a regular interval) with a button control that is conditionally displayed 2. The button control should show a ModalPopup of a Panel that serves as a form 3. This Panel form contains a textbox populated with a value from the gridview and another dropdown control I can get 2 of these 3 requirements via a couple of different approaches (like 1+2 work, but 3 fails or 2 +3 work but 1 fails).The code pasted below is the closest I have gotten, and is actually my preferred method, and I was wondering if anyone could tell me why the ModalPopupTextBox1 is not rendered when ModalPopup button is clicked.If I place the Gridview1 outside of UpdatePanel1 (refresh controlled by Timer1), the ModalPopup Panel works as expectedMarkup: GridUpdate.aspx
my problem is related with modalpopup control. i made a login control using it.
This works fine. Problem is this. When i click btniptal and then i refresh the page modal shows again. But When i click btngiris and then i refresh the page modal doesn't show. When clicking the btniptal button, the modalpopup should not show.If i make this codes in aspx page everything is ok. But i make this in usercontrol.
I have a modalpopup extender attached to a button. That is to say the button is the targetcontrol id of the modalpopupsxtender. I would still like the onclick event of that button to work because only the onclient click event is working. How can i go about this.
I've got a UserControl that's used inside of an UpdatePanel. The UserControl is a fairly simple form that appears via a ModalPopupExtender (which is also part of the UserControl). There are four DropDownLists, as well as some other UI elements. Three of the four DropDownLists have AutoPostBack="true", with SelectedIndexChanged events that fire on the server and cause some of the other DropDownLists to rebind. Two of the three DDL's that AutoPostBack are working fine. One of them, which I only just added, is showing some strange behavior. Let's say I bind five Items to it: 1, 2, 3, 4, 5. I set the SelectedIndex to 0, which makes 1 the selected item. If I select 5 and then 1 and keep toggling back and forth, everything works fine. The postback occurs and SelectedIndexChanged fires. Every time. If I ever select 2 or 4, the postback occurs but SelectedIndexChanged does not fire. Every time.
If I ever select 3, something bizarre happens and sometimes the value of the DDL reverts to 1. Even though breakpoints seem to show that it's not rebinding and no unexpected code is running. I know your first instinct will probably be that I'm wrong about the rebinding code not running, but I have literally been staring at the debugger for hours trying to find my mistake. Lots of breakpoints. I don't get it -- this really isn't that complicated. But obviously I am missing something. I've put about four hours into this so far and I think I'm just grinding at this point. I could use another perspective.
HTML (and by the way, DropProtocolCycleID is the problem control): <asp:Panel ID="PanelPopupAssign" runat="server" Style="display:none; cursor: move; width:325px; background-color:Transparent;"> <BlueUI:Panel runat="server" ID="PanelPatientProtocol" Width="500px" HeaderText="Assign Protocol"> <table cellspacing="5"> <tr> <td style="width:150px;"></td> <td style="width:50px;"></td> <td style="width:125px;"></td> </tr> <tr runat="server" id="TableRowCategory"> <td align="right">Category:</td> <td colspan="2"> <asp:DropDownList runat="server" ID="DropProtocolCategories" CausesValidation="false" autopostback="true"/> </td> </tr> <tr> <td align="right">Protocol:</td> <td colspan="2">..............................
I get following error when I click on the button.I am Using IE 7.0 and Updatepanel control for AJAX in the aspx page (Not in master Page).This error goes After I clear cache.
