AJAX :: ListBox ListItem Edit Via ModalPopupExtender

Mar 17, 2010

I have a listbox. There is an edit button beside it. When users select an item from the listbox and click the edit button, a modal popup extender pops up. The modal popup extender contains a textbox and a button (edit). When they edit the content, they canclick the button again, which will close the modal popup extender and update the text of the selected item.Users want an option to add '<br />' to the item in the listbox, so when the text from the listbox item is displayed in some other page, it shows up in multi-line format. However, when I add '<br />' to the edit text and hit the edit button, I get ajax error that does not close the modal update or edit the text in the listbox. However, if I type in '<>' or just 'br /' in the textbox and click th edit button, it works. In fact any text inside the < and > triggers the error. Here's the error I get.

AJAX :: Edit ModalPopupExtender In Gridview Control?

Feb 24, 2011

I have created ObjectDataSource control which is bind with the GridView control (In few cases with DetailsView control) as well as I have created new column "Edit" in gridviw with Linkbutton.

Now whenever user clicks on linkbutton it shows ModalPopupExtender with edit fields for that particular selected gridview row.

My problem is that I want to show only few columns in gridview (eg- EmpID, EmpName) and want to edit all columns in modalpopupextender (eg- EmpName, City, State, Pincode etc).

So how can I show all the fields in modalpopupextender to edit becouse when I am reading fields from GridViewRow not able to get the hidden fields which is not included as columns in gridview?

Somehow can I read fields values from ObjectDataSource?

AJAX :: ModalPopupExtender -- Fetch Data In Modalpopupextender

Apr 7, 2010

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.

AJAX :: How To Use ModalPopupExtender In UpdatePanel

Feb 5, 2010

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?

this is my final solution:

AJAX :: How To Use A ModalPopupExtender And Set The PopupDragHandleID

Jun 30, 2010

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.

AJAX :: Found A Bug In The ModalPopupExtender?

Feb 9, 2010

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.

AJAX :: ModalPopupExtender Control?

Nov 30, 2010

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:

http://www.laneros.com/attachment.php?attachmentid=185893&d=1290707244

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:

AJAX :: 4.0 ModalPopupExtender Pops Under?

Apr 23, 2010

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.
