AJAX :: Calling ModalPopupExtender Using Querystring?
Nov 18, 2010
I am trying to call modalPoupuExtender using url +queryString. which opens fine but when i write some text in textbox and submit. it shows page.isvalid = false.
i commented the page.isvalid the i realized txtbox is empty.
html bit inside modalpopupextender. below is how i am trying to get the value
[Code]....
dim tbx as textbox = TryCast(Me.dvCustomerDetail.FindControl("txtComment"), TextBox)
I am using Visual Studio 2010 and working on an ASP.NET web application targeting .net 4.0.I am using the Ajax control toolkit version 4.1.40412.2In my .aspx page I have the following:
[Code]....
In the server side code for the lbAddMember_Click event I have the following:
[Code]....
If I click the lbDummy button the popup will show as expected however if I click the lbAddMember button I can trace the server side code and it is being called but the modal popup does not ever showThis works if running with FireFox but does not work when running IE. Here is the other stange thing. This has been working in IE for last few weeks but just started not working this week.
I would really appreciate if someone can find out what's wrong with this code.
Here is my question. I have textboxes in a modal popup extender (City, state, zip) and there is an image button search for searching the address from the database. All this functionality is within a control (.ascx file). This control is added to the page where it needs to be displayed and is being displayed when a user click the Address button (the code for it is not shown here). The method ShowAddressSearch() in the control is being called from the page and it displays the popup.
When the user enters any of the 3 values and hits search a server event is fired up and the result should be displayed in a grid. What is happening is, when the user hits the search button the server call is made and the data fetched from the db but the modal popup closes itself here is the code for this. I would really appreciate if someone can find out where and how popup is getting closed.
I have a modal popup extender with one control (ascx) this control has a label that on onclic method call other popup extender.
It's has other ascx, it's has a button for a search. When I do Click in this button in first time, the event click not fired and there are a javascript error that say "this._activeDRagVisual is null reference".
In the other hand, If a use de second popup inside an asp page the event and control work correctly. The problem is with the popup inside popup.
I have a gridview inside a ModalPopUpExtender, the grid view have the button add delete and edit when i clic one of the button of the gridview the popup is closed. I wont to close the popup when the close button is clicked.This is the asp.net part:
I try I cannot seem to find a satisfactory solution. As far as I can tell from the documentation a ModalPopupExtender should be able to reside inside an UpdatePanel. However, I simply cannot get it to work.After the first refresh of the UpdatePanel I get errors of various kinds depending on what I've tried.
What I'm trying to accomplish is having a button inside an UpdatePanel which launches a popup. Another button inside the UpdatePanel causes a partial postback. And finally a button within the popup has to cause a partial postback. I have tried at least five different approaches to this problem and finally I gave up and went with a very inelegant solution. I don't think my requirements are all that strange, am I doing something wrong?
First I tried this:
[code]....
This works fine until after the first postback when the Cancel-button (Button4) starts causing synchronous postbacks and the textbox starts to fill up with commas. I also tried the same as above but placing an UpdatePanel within Panel4 (the popup) - no go. Then I tried causing the postbacks in javascript launched from the ModalPopupExtender's OnOkScript - still it starts failing. I tried another couple of attempts all of which failed. Finally I decided to move the ModalPopupExtender outside the UpdatePanel, add dummy buttons and a bit of javascript to launch and hide the popup. Although this satisfies my UI requirements it just plain wrong from a design perspective and it annoys me that I could not get the extender to work inside an UpdatePanel. Has anyone succeded with placing a ModalPopupExtender in an UpdatePanel with the requirements I stated above? Or should it be added to the list of controls that's just not compatible with the UpdatePanel?
i try to develop a login control with modlpopupextender within usercontrol. i have a problem with hiding modalpopupextender. i indicate that if i put modalpopupextender in aspx page directly it works, but when using in usercontrol it doesn't. my codes are:
[Code]....
[Code]....
i show modalcontrol on masterpage. it is ok. i click btniptal,modalcontrol hides. but after click the btniptal, if i refresh the page(postback) modalcontrol shows again. i said this above that if i put modalcontrol directly masterpage ,thing that i said doesn't happen. how can i solve this.
I have ValidationSummary in masterpage out of UpdatePanel and inside updatePanel i have my ContentPanel. I have an user control where iam having Save button which iam using in all my pages of application. Now i have a requirement like i need to show the validation summary in ModalPopUpExtender.
We use a ModalPopupExtender and set the PopupDragHandleID so it can be dragged around the browser.
This works great in most browsers; however one control that is loaded in the ModalPopup is wrapped in a scrollable div, and in Safari when you click on the scrollbar and then move the mouse it starts dragging the modal popup around.
I was hoping someone either has a fix for this issue, OR knows how to detect the browser in either css or javascript and remove the PopupDragHandleID.
I think I've found a bug in the ModalPopupExtender. Here is the details:
Problem
When you use ModalPopupExtender within an UpdatePanel, the controls in the PopupControl (the Panel containing the content needs to be poped up) will be rendered, even though the NamingContainer (or the parent) of the ModalPopupExtender and the PopupControl is set to invisible. This may cause Event Validation error between AsynPostBacks. Cause
The controls in the PopupControl will not be rendered within the UpdatePanel, but at the bottom of the page outside the UpdatePanel. When the NamingContainer of the PopupControl and the ModalPopupExtender is set to invisible, the content outside the UpdatePanel won't be updated and therefore stays on the page.
Code
Default.aspx
[Code]....
Steps to reproduce the problem
Create a simple ASP.NET web application in VS using the code provided aboveRun the app in debug modeClick on button Show 1, and then click the link button Show. The popup panel should show up. Click either OK or Cancel to close out the popup panel.Click on button Show 2. You will see the content in the popup panel is displayed at the bottom of the page. However, the content should be invisible and should not be rendered, or should be removed from the page.Click on button Show 1 again. You will see the familar error message: Sys.WebForms.PageRequestManagerServerErrorException: Invalid postback or callback argument...
Further explaination
This error has nothing to do with the ViewState. When button Show 1 is clicked the second time, the page will try to load data (including ViewState, PostData and Session) into the controls on the page before btn1_Click is called. At this moment, pnl1 is still invisible, so the page will only try to load the data for the controls in pnl2. However, if you check the Request.Form.AllKeys in the watch window, the TextBox txt is part of the PostData. This doesn't match any control in pnl2, and then the exception is thrown.
I have tried many different ways, but none of them worked.
I am developing a web portal under ASP.Net 4 and using Ajax and masterpage. I created a user control to select a data from a gridview and put it in a textbox, for that use the ModalPopupExtender control. Everything works fine as can be seen in this photo:
But after much control to use the ModalPopupExtender starts to appear behind the form and to return to appear before touching refresh the page or press the button repeatedly calling him. In the next picture you can see what it looks behind the popup form:
using a modalPopupExtender inside an UpdatePanel (the popup control is a Panel), the popup acts normal (renders on top) using the modalPopupExtender.show() command to display. If you cancel the popup, the next popup will be under the other controls on your page. I have another modalPopupExtender which is not being displayed through the show command but is activated by another control. This one works normally. So something is going on with the show() function inside an UpdatePanel. If I remove the UpdatePanel, both popups work normally.
I've been prototyping the use of the ModalPopUpExtender but find that the BackgroundcssClass fills the entire screen even though I have defined the width and height. So when I click on link button the popup fills the entire window and the X/Y positioning has no effect. Other than that the content displays fine. Any thoughts on this issue?
Am trying to get a modalpopupextender working, and it's driving me insane. I can get the popup to show, but it fills the whole browser. How do you set the size of the popup?
Here is my code:
[Code]....
Also the popup is not transparent, how do I make it so. The css I am using for the popup is as follows:
I have a user control with OutputCache set to vary by any param (*). This user control has a LinkButton, which when clicked, causes a postback, and displays a ModalPopupExtender (the extender's TargetControlID is a dummy link). The user control is included on an aspx page.
The LinkButton is displaying the popup just fine. But if I open another browser tab/window/type, the LinkButton fails to generate the popup. I've tried (all separately):
moving the popup extender and its associated control to the main aspx page use OutputCache Location="None" on main page dynamically create the Popup extender and its associated control in Page_Init of both ascx and aspx
I have created a panel with a CheckListBox populated from a SQL datasource, an OK and Cancel button. I have set up the OnOKscript to work and I can click the OK button and populate a label on the page. On the OK click I want to get the selected Checkboxlist values.In the page I have added this
<script type="text/javascript function SaveRREData() {
I have a typical frameset page that separate the page into Top, Left and Main. I want to add modalpopupextender on the frameset page so that it covers the WHOLE SCREEN.------------- Default.aspx file ---------------
I have a gridview with a template field containing a Button and a modal popup extender. I would like to populate the panel with the information from the row ... is there any way to do this?
I have a ModalPopupExtender in markup. When I try to attach to it in javascript using getElementById('ModalPopupExtender1') it doesnt work. So when I viewsource code it on shows up as a function. Why?
