Im having problems with AJAX update panels and accented words like á,é,í,ó,ú. AJAX update panel change them to another character.

Any help about that

Feel free to email me and we can look at your code.

Joe,

I am getting and error from your AJAX Control Modal Popup Extender Demo; Microsoft JScript runtime error: Object expected

www.asp.net/.../video-84.aspx

I have try to get this to work in two different ways;

First my code as percieved from your demo -

----------------------------------------------------------- ----------------------------------------

<%@ Page Language="VB" AutoEventWireup="true" CodeFile="Default.aspx.vb" Inherits="_Default" %>

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %>

">www.w3.org/.../xhtml">

   

------css code------------------------------------------------------- ----------------------------------------------------------- ------------------

}

.modalBackGround

opacity:0.7;

}

----------------------------------------------------------- ----------------------------------------------------------- ----------------------------

When I could not get my code to work I copy/past'd Jonathan Shen's post into a new ajax web site (download from your demo site is a diffent project).

forums.asp.net/.../1762667.aspx

This code gives me the same error; Microsoft JScript runtime error: Object expected

I did need to make two changes to the code;

Johan's code looks like ---------------------------------------  

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

                 PopupControlID="PanelContainer" BackgroundCssClass="modalBackground" DropShadow="true"

                  OkControlID="OkButton" OnOkScript="onOk()" CancelControlID="CancelButton"  />

My code in the new project looks like -----------------------------------------

<%@ Page Language="VB" AutoEventWireup="true" CodeFile="Default.aspx.vb" Inherits="_Default" %>

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %>

TargetControlID="LinkButton1" PopupControlID="Panel1"

BackgroundCssClass="modalbackground" CancelControlID="cancelButton"

DropShadow="True" OkControlID="okButton" onokscript="onOK()">

</cc1:ModalPopupExtender>

I do love your viedo's.  Please keep'm coming.

Thanks

Greetings Joe!

this is a great demo, I am going to give it a try, I am downloading the video now. To be able to have popups in a web application is really fantastic!

Mainly, I would need a popup after I excute a certain server side code, and then return  the results for the user in case of an error in a popup.

There is something else I wonder if it can be done with Ajax, or maybe SilverLight SDK which I haven't had a look at, It is when the whole web pages gets shaded out and then once the user clicks on the popup message, then the page goes back to normal state and becomes accessable. I tried to look for any demos for that on the Ajax videos page, but couldn't find anything for shading the page.

ohh! I don't see my picture next to my comment, I did upload my photo when I was editing my profile the first time, so weird it is not visible here. I'll probably have to try to upload it again.

Dear Joe,

I have been trying to find a way to control the popup from my server side code, what I need to do is display the popup based on a certain condition, so far  the popup panel will come out whenever I click the submit button.

any suggestions Joe?

thanks mate!

How to use the popup extender dynamically in our web page  i want to keep popupextender as a tooltip for the grid.

I am using the pop control extender in a masterpage file in a vb.net web application.  The popup control extender works fine in all pages except in a page I have for viewing reports which uses a Crystal Report Viewer.

In this particular page, the pop control extender does not work.  I am not able to see the popups when I click the corresponding links.

Is there a reason for this?  Does it have a fix or is it just that they do not work together?

Thanks,

Jamie

Thanks for the video. I was wondering if there is a way to display the panel by different events like mouseover.

Thanks

Alex

wondering if graphis could also be displayed

I downloaded the code and ran it on winsows vista with iis, and it works like the example withouth ajax..when I click on the button all three labels refresh

I am getting an error called cannot assign to '[string]'..

I am using C# and i followed your video

It is simple and good....

its nice video

I'm having problems with the popupcontrolextender when I use the < and > characters as part of the value inside the textbox. If I take those characters out, it works fine.

Here's the ASP code:

----------------------------------------------------

       PopupControlID="Panel1" CommitProperty="value" CommitScript="" Position="Bottom">

   </ajaxToolkit:PopupControlExtender>  

Here's the VB code

-----------------------------------------------------

   Function getlistselections(ByVal emailList As CheckBoxList) As String

       Dim result As String = ""

       For Each lst As ListItem In emailList.Items

           If lst.Selected AndAlso lst.Value.ToString <> "" Then

               result = result + lst.Value.ToString + ","

           End If

       Next

       getlistselections = result

   End Function

   Protected Sub Button3_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button3.Click

       Dim selections As String = GetListSelections(CheckBoxList1)

       If Not (String.IsNullOrEmpty(selections)) Then

           PopupControlExtender.GetProxyForCurrentPopup(Me.Page).Commi t(selections)

       Else

           PopupControlExtender1.Cancel()

       End If

       CheckBoxList1.ClearSelection()

   End Sub

i want ot ask something if i have text and value for RadioButtonList and i want to get the value that user selected in variable and use it in vb code

Thank for great demos It helps a lot.

But for some reason on one of my computers I have no audio.

What should I do to fix it? I am using Media Player 11 on Windows XP on both machines.  One has audio of demos working

fine another one is silent.

Thanks again

Hi

I m very new to web application. I use your demo to make a popup application.

I have a question

I have a textbox and an OK button when user click the ok button the value in the textbox will store in a variable.

u can mail answer on adeel2083@yahoo.com

Thank you for the popup control extender demo. However, can you use the control for Gridviews, listviews, etc. in Visual Studio 2008; is there code for that?

Thats a very good example. But my requirements are something different. I have been trying to find a way to control the popup from my server side code. What I need to do is display the popup with Yes/No buttons based on a certain condition and executes the remaining code based on the Yes/No button clicked. I went through your code, but this didn’t helped much since it only shows popup when I click the submit button on my asp page.Can you share some thoughts on this.

KuntalShah I believe I have an answer to your comment.

First, Make a dummy button to use for the okControlId. In this button set the style ="display :none"

Next, Add another button. In this button do your logic in the code behind and afterwards set your extender.show()

This will allow you to condition the popup extender.

Also, you can hide your extender like this extender.hide()

Here is an example:

HTML

<asp:Button id ="btnTestNew" runat ="server" Text ="OKFAKE" style="display :none"  />

<asp:Button id ="btnTest" runat ="server" Text ="OKREAL"/>

CODE

Protected Sub btnTest_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnTest.Click

       Dim test As String

       test = "WHOOPIE IT WORKED"

       Me.ModalPopupExtender1.Show()

   End Sub

Great Demos!  I'm using the popup extender control in a gridview.  I have an image in each row that displays a panel on mouseover.  It works fine until I try to use it on a user control.  I think it's failing on the javascript Find method.  It can't find the control using the behaviorID that I set for the image control.  Do you know how I can get around this?

can i open any existing page in popup extender....???

Thanks! Jërëjëf!

Hi Joe,

This is a great Demo! Unfortunately the PopUpExtender fails to pass the value to the text box when the RadioButtonList is dynamically built from a database source.

I compared the source code of the pages, but I do not see any noticeable differences between this example and the one that I created.

When I debugged the code, SelectedValue returned empty. And when I tried to use SelectedItem.Value instead and the application threw an exception.

I disabled the database code and hard-coded the radiobutton list and the app worked!!!

Any help is appreciated.

thanks,

Andy

Hi again Joe,

I figured 2 ways out.

I forgot to close the DataReader using the Close() method.

But, the one below was something that I tried first.

I explicitly iterate thro' the DataReader Object and added ListItem Objects to the RadioButtonList control.

In Short, I replaced this code:

makeReader = sqlCmd.ExecuteReader()

rblMake.DataSource = makeReader

rblMake.DataBind()

With this:

Try

While makeReader.Read()

Dim tempMake As String, tempMakeID As Integer

tempMakeID = CInt(makeReader("MakeID"))

tempMake = CStr(makeReader("MakeName"))

Dim lstItem As New ListItem

lstItem.Text = tempMake

lstItem.Value = tempMakeID

rblMake.Items.Add(lstItem)

End While

Catch ex As Exception

Finally

makeReader.Close()

End Try

The application works using either of the 2 fixes.

Thanks!

How exactly can we use this ajax control to popup an .aspx page with it's own controls on it.  I don't necessarily want to embed all the functionality of the popup window in the original page, so that's why I want to just show an .aspx page with all it's own functionality.

Thanks!

The below link will help you on what you exactly want

I have a modalpopupextender that when it displays the background creates scrollbars (vertical & horizontal) and extends the the background beyond the visible page.  Any thoughts?

Hi, keep up the good work! I followed this tutorial and created a popup to an imagebutton for editing a field. In the popup I have a textbox and a button. When I click on the button I get a jscript postback error (this._postBackSettings.async is null or not an object). The weird thing is that I never used to get it when I was using vs2005 but when I upgraded to vs2008 and ajax 3.5 I have this problem now. Can anybody help me?
