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.

AJAX :: Selecting Listbox In Updatepanel To Trigger Modalpopup?

Aug 17, 2010

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.

AJAX :: ModalPopup / UpdatePanel From Codebehind, Inconsistent Behavior OnClick?

Aug 4, 2010

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!

AJAX :: Web User Control And Modalpopup Extender?

Dec 16, 2010

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.

AJAX :: User Control With ModalPopup In A Repeater?

Dec 24, 2010

I have a user control that contains a modal popup extender.

I am using the user control inside of a repeater so it could be shown multiple times on a page.

Everything works fine if the repeater only contains one item.

When there are multiple user controls on the page I get the following error:

"Microsoft JScript runtime error: Sys.InvalidOperationException: Two components with the same id 'PosAdjPopup' can't be added to the application."

How do I get my user control to work with the modal popup extender when it will be used multiple times on a page?

Can I keep the modal popup extender in the user control or do I have to put it on my aspx page and trap the event on the button click?

AJAX :: ModalPopup Not Working With A User Control?

Feb 7, 2011

I have three modal popups that are working properly because I test it the controls with simple plain text.

I placed a form view and a datalist in the first two modal popups and everything seems to be okay.

I need to place a user control in the third modal popup but everytime I place the user control I get a javascript error for that particular modal popup.

When I copy paste the same modal popup on a blank page and place the user control inside of the panel then the modal popup works perfectly fine.

I basically copy/paste the same code back where the other two modal popups are then I get the same JavaScript error.

The modal popup crashes first on:

AJAX :: ModalPopup As An .ascx Control To Be Triggered By Hyperlink?

Sep 29, 2010

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...

AJAX :: ModalPopup Triggered From Item Template Control On A Gridview?

Mar 29, 2010

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

DropDownList In ModalPopup / UpdatePanel Intermittently Doesn't Fire SelectedIndexChanged

Feb 4, 2010

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">
