I have a gridview control in which rows have textboxes associated with a PopupControlExtender. The popup is just a panel with some checkboxes, ok, cancel buttons, etc. When the popup is shown and the Ok button clicked, I need to know which row in the grid, or which textbox in the row, is currently associated with the shown popup. How do I accomplish this?
View 6 RepliesI have a textbox which uses a popupcontrolextender. I would like the textbox text to be populated on page_load with default text. If I do this the page does not recognize the textbox as having text when the form is submitted. Why does the popupcontrolextender do this to the textbox and how can I make this work?

I'm using PopupControlExtender in a GridView, which pops up various dropdowns, treeviews, calendars etc. depending on which cell is clicked. I'm populating the dropdowns on the OnPreRender event. The result is, GridView is becoming extremely slow. I've tried removing Calendar controls, the Grid is still very slow. My guess is the enormously large source view of the page, resulting from populating controls on PreRender. Here is a sample ItemTemplate:

My goal is to populate the controls inside popup panel only when that panel becomes visible. I tried using OnResolveControlID event for this in PopupControlExtender. But strangely enough, that event fires only when control is NOT found, contrary to what its name suggests.
Anyway, my goal is to populate the popup panels controls (mainly ListControls) ONLY when their container panel becomes visible - hoping that this will make the grid faster. The same grid works perfect with AutoGenerateColumns=true and no populating of ListControls (not an option). Also, I'm NOT using debug option in web.config.
I have popucontrolextender inside gridview and by using dynamicservicemethod I could pop out panel. I followed following article to accomplish this.

However, one of my popup takes a while to come up and I am sure users doesn't want to wait that long for panel to pop up. I want something like progress bar image to come up after user hit the row in the gridview. I can do this in modalpopupextender but I can't find any example to accomplish this using PopupcontrolExtender inside gridview using dynamic service method.
I have a 20 PopupControlExtenders for 18 columns in a GridView. Every popup is has different content: HtmlSelect, HtmlAnchor, HtmlButton CheckBox etc. etc. -depending on the cell it is clicked on.
I'm using combination of DynamicContextKey, DynamicControlID and DynamicServiceMethod to populate these popups.
The problem is, when the grid is first loaded, all popups in all columns populate correctly. Problem arises when I flip a page in the gird. On the new page, the popup comes up, but there is no content. And NO error (like 500 or something). Now when I go back to the first page, no popup shows content here either. What am I doing wrong? Here is a sample ItemTemplate:

I have an web application with a masterpage, a modalPopupExtender to insert new records, and and updatePanel with a gridview inside, which I have modified the edit and delete buttons into a templateField to allow the use of a confirmButtonExtender.The problem is that I cannot edit (you click on the edit button, you modify the record, but I cannot confirm the edit).But, if I show the modalPopup (it doesn't matter if I insert a new record or not), the, the edit works, anyone knows what could be?
View 5 RepliesI change the styles of the rows normal, alternate and selected via stylesheets. Additionally I implemented onmouseover, onmouseoout and class with gv_Alternativen_RowDataBound.
But when I do a mouseover in the selected row, the wrong onmouseout is placed there:
Protected Sub gv_Alternativen_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gv_Alternativen.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow Then

How can I insert into a table, parameter values that are determined by the SelectedRow in a GridView without the " " text in Null cells?
Why does " " appear in the database table and not in a Label.Text on the form?
What is the easiest way to prevent from being inserted into the table from a GridView SelectedRow null cell value?

View 1 RepliesI have a toolbar at the bottom of my site, wrapped in an lwaysVisibleControlExtender. When I press on the of links on the bottom, I want a popup to appear such that it appears joined to the link on the toolbar (very much like facebook chat).

View 4 RepliesI use the PopupControlExtender to show a Panel after clicking a ImageButton. The Panel can be closed by clicking the page outside the Panel. This is working fine.I added an Animation Fading Out the Panel when the Panel is clicked (I have no close button on the panel). This is working fine too.The problem comes when I click the Imagebutton (The Panel appears) followed by clicking the Panel itself (The Panel disappears). If I now click the Imagebutton again, nothing happens as if the animation was not considered finished. The Panel should have appeared again.
If I change the focus on the page, then the animation is in some way reactivated and the popup works again. I already tried the following :
- <EnableAction AnimationTarget="ImageButton1" Enabled="true" />
- Setting the focus to a random control on the page using <ScriptAction />
<asp:ImageButton ID="ImageButton1" runat="server" ImageUrl="~/App_Themes/Images/Vraagteken.gif" OnClientClick="return false;" UseSubmitBehavior="false" ToolTip="Kies de bedrijfs sector waarvoor de tekst is bedoeld" />
I know this may be easy, but I have looked at it for a bit of time and maybe my brain is going in circle.OK, I am learing PopupControlExtender. Looks like it is a good thing to have. One (style of) example is to have a TextBox. Click on it and the PopupControlExtender will come up. Sample code may be like the Example 1 in this
Introduction.
Question:
Why there is a need to put UpdatePanel inside the Panel? It is the TextBox which needs to be updated. Why the TextBox is not put into an UpdatePanel? (I try Example 1 and it works without having to put the TextBox inside an UpdatePanel.)
I am using C# Multiview on a log-in/forgot user name page and I would like to avoid new windows each time I change view id inside the Multiview.Right now the page uses "window.showModalDialog" and I would like to remove the js from the page.This lead me to the PopupControlExtender. How do I use the PopupControlExtender and Multiview in combination? e.g. a radiobuttom provides the desired view index and only this view is shown in the pop-up?Did I misunderstand the purpose of the extender?

As the subject says: I am wondering what the ExtenderControlId attribute of the PopupControlExtender is used for? When I click "Add Extender" through the context menu of an control in the designer, the code of a PopupControlExtender is generated, but the ExtenderControlId attribute is empty. By the way: Is there a documentation of the AjaxControlToolkit-Controls which provides a description to every Member like the ExtenderControlId?
View 1 RepliesI am displaying links in gridview. When user clicks on link....big image is displayed. Everything is working fine.
As of now i am redirecting user to LargeImage.aspx..where i am able to display the largeimage.
But I need to display the large image within a popup in the same page where gridview is present.
User must be able to close that popup and return to the page(containing gridview).
I would like to do it with a popupcontrolextender.
I have two pages with TabControls and the tabcontrols have several tabpanels. On one page there are some popupcontrol extenders on the first tab, and that page works fine. On the second page, the popupcontrolextenders are on the second tab. When that page loads, I get the following jscript error:
Microsoft JScript runtime error: Sys.ArgumentException: Value must not be null for Controls and Behaviors.
Parameter name: element
I've tried setting the Enabled property to false for these popupcontrolextenders until that tab becomes visible. This prevents the error on page load, but but then the same error happens as soon as that tab becomes visible.
Is it possible to use a popupcontrolextender on a tabpanel, or should I give up and try something different?
I have a text box with an associated popupcontrolextender.This opens a panel containing a checkboxlist. What i want to do is add the values selected in the checkbox list to the text box when the user clicks out of the panel.I started to use the OnselectedIndexChanged, of the checkboxlist and update the text box after every checkbox has been checked / unchecked.But the checkboxlist is quite long and when you click one of the checkboxes near the bottom,because everything is in an update panel,the checkboxlist scrolls to the top after the autopostback not very user-friendly.
I have a PopupControlExtender inside of the UpdatePanel. I use it to edit some of the values on the website.
Basicly it looks like this. If you have PopupControlExtender inside of th update panel whenever a user triggers a partial postback javascript creates the popup panels outside of the UpdatePanelControl - to make sure they are always on the top of other elements. So after every postback you get more and more elements with the same clinetIDs.
Here is a code from Firebug - you can notice Panel1 and all the controls inside of it being generated 3 times when i load a page (once) and twice after two partial postbacks:

Oh and i use it actually inside the listview that itself is embeded in the update panel so i cant really use it outside of the update panel.

Does anybody have recent information on surmounting zorder problems with the PopupControlExtender? Web searches found a few comments that seem directly related to the problem I'm having, but no solutions... Most-suggested solution is to set the z-order to a high value on the panel containing the popup markup, but that is helping me (and didn't seem to fix the problem for others either). I'm using popup extenders within the EditItemTemplate of a ListView, and however hard I try I always end up with the other records in the listview (i.e. those using the ItemTemplate) overwriting the popup markup.I had high hopes that this problem might have gone away with release 40412 of the toolkit but it appears not
