Postbacktrigger problem

I am creating a vb.net/asp.net 2005 app using a tabcontrol and I am trying to use a button inside the updatepanel and inside the tab and I am using the following syntax:

<CODE>

<asp:UpdatePanelID="pnlTest"runat="server"RenderMode="Inline"UpdateMode="Conditional">

<Triggers>

<asp:AsyncPostBackTriggerControlID="TabContainer1"EventName="ActiveTabChanged"/>

<asp:PostBackTriggerControlID="btnPreview"/>

</Triggers>

<ContentTemplate>

....everything else here...tab control...

</ContentTemplate>

</CODE>

But I keep getting an error as follows:

<ERROR>

A control with ID 'btnPreview' could not be found for the trigger in UpdatePanel 'pnlTest'.

Description:An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details:System.InvalidOperationException: A control with ID 'btnPreview' could not be found for the trigger in UpdatePanel 'pnlTest'.

</ERROR>

I am very confused because I know the control is there and when I go to the vb code-behind I am able to see the code in the dropdownlist that contains all controls for the aspx page. Does anyone have an idea what I'm doing wrong? thanks

Since your button is in the UpdatePanel you do not need to create trigger for it.


Hi Myroncope,

Here is my sample code which was written in c#. It has been tested and works fine. If you install a tool named "Web Development helper", maybe an error dialog will be sent to you, don't mention it.Press continue!

<%@. Page Language="C#" AutoEventWireup="true" CodeFile="UpdatePanelTest2.aspx.cs" Inherits="UpdatePanelTest2" %><%@. Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"> <title>Untitled Page</title></head><body> <form id="form1" runat="server"> <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <asp:UpdatePanel ID="UpdatePanel1" runat="server" RenderMode="Inline" UpdateMode="Conditional"> <Triggers> <asp:AsyncPostBackTrigger ControlID="TabContainer1" EventName="ActiveTabChanged" /> <asp:PostBackTrigger ControlID="btnPreview" /> </Triggers> <ContentTemplate><%=DateTime.Now.ToString()%> <cc1:TabContainer ID="TabContainer1" runat="server" OnActiveTabChanged="TabContainer1_ActiveTabChanged" AutoPostBack="True" > <cc1:TabPanel ID="TabPanel1" runat="server" > <HeaderTemplate> 1111</HeaderTemplate> <ContentTemplate><%=DateTime.Now.ToString()%></ContentTemplate> </cc1:TabPanel> <cc1:TabPanel ID="TabPanel2" runat="server"> <HeaderTemplate> 2222</HeaderTemplate> <ContentTemplate><%=DateTime.Now.ToString("yyyy-MM-dd")%></ContentTemplate> </cc1:TabPanel> </cc1:TabContainer>  <asp:Button ID="btnPreview" runat="server" Text="btnPreview" /> </ContentTemplate> </asp:UpdatePanel> </form></body></html>
 By the way, my AJAX Control Toolkit version is 10618. If an error occured while you execute the code above. Suggest you check your AJAX Control Toolkit version.
If the error information still exist, please let me know.

Are btnPreview visible?

You could also try to use the ClientID or UniqueID value of btnPreview for postbacktrigger's ControlID attribute. Maybe one of them works.

And finally you could also tryRegisterPostBackControl(Control) method of scriptmanager in code-behind.


Hi, MyronCope

You can add an invisible button out of the updatePanel,set the invisible button as aPostBackTrigger of theUpdatePanel.

Then on the client-side click event of the 'btnPreview', trigger the click event of that invisible button.

<div style="visibility:hidden"><asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" UseSubmitBehavior="false" /></div>

<input type="button" onclick="javascript:document.getElementById('Button1').click();" name="Button1" value="Button" id="'btnPreview'" /></div>

The same solution solved all of this kind issue!

Preselecting a value in the CascadingDropDown control

G'day,

I have a form that saves and loads data from a database. Creating new forms is fine however when reloading hthe form for editing I want the CascadingDropDown control to have its previously selected value displayed.

I have tried the obvious such as loading the controls data and using SelectedValue = someId but it didn't work (probably not surprising!). I also tried setting the controls Text property incase Atlas detected a non empty value and left it alone. I had a bit of a look at the source but I don't yet know enough about the architecture to answer the question myself or to write some code.

Is there a way in this version of preselecting a value when setting up a form from server data on an initial page load?

Keep up the good work guys!

Regards,
Steven.

If you put the following code into the Page_Load for the CascadingDropDown.aspx, it will initialized the first item:

CascadingDropDown1.TargetProperties[0].ClientState ="BMW (value)";

Unfortunately you can't do this for other ones because the change of the first item to the specified value will clear the subsequent items, so we'll need to make improvements here.

But in general the idea is that you should be able to set the ClientState to be the string version of thevalue you want to set (not the text label).

Thinking more about this I think there's a few things we'll do in a future release (might not make our next refresh):

1) Add a strongly typed property for this e.g. "Selected" value

2) Try to make it so the value doesn't flash before the text gets set

3) Make sure you can do more than just the top level here.

Thanks for pointing this out, it's good feedback.

Thanks,

Shawn


So, am I to understand that currently values cannot be selected in dependent lists based on data that that was retrieved from a database?

When I user selects an item to edit, I populate the form with all the existing data for that item, however, some of my dependent lists are not getting the SelectedValue set.

I have an Account list (the parent), I am able to set its SelectedValue.

Sub-Account, Contact, Network and Gateway are dependent on Account. Gateway Version is dependent on Gateway.

When I populate my form the SelectedValue is set successfully for the following lists:

Account, Gateway, Gateway Version

The other lists are disabled and show the PromptText. This would be less confusing to me if ALL dependent lists were disabled with the prompt text selected.

Is there a way to make this work? Or do I need to abandon the CascadingDropDown and find another solution?

(My original post:http://forums.asp.net/thread/1383830.aspx)


It sounds like you have a 1:many parent:child relationship going on here. If so, then I think I fixed the problem withwork item 1704. Please trya recent development release and let us know if it's still not working.

(My app is a ticketing system)

I downloaded the Wed, 30 Aug 2006 17:53:43 GMT version and it solved my issue with the values of the "child" lists not getting selected when viewing/editing an existing ticket. However, now when I go to add a new ticket, my page hangs when it loads the CascadingDropDowns. My cursor becomes an hour glass and my browser becomes unresponsive. My lists never get populated, not even the "parent".

Eventually I get this error: "A script on this page is causing Internet Explorer to run slowly. If it continues to run, your computer may become unresponsive. Do you want to abort the script?"

I'll download a different development release while I wait for a response and see if that makes a difference.

(Side note: I was going to upload a screen shot of the error, but I don't have permission to perform uploads.)


It sounds like either you have a circular reference in your page - or CascadingDropDown is adding one. :) If nothing stands out for you, please post a simple sample so we can have a look. Thanks!

If I add the CascadingDropDownProperties like this (below) the "Add New Ticket" pages hangs on load. However, the "Edit Existing Ticket" page will load/populate just fine - including all of the "child" lists.

We'll probably need the corresponding web service (or one that returns close enough data to reproduce the problem), too, please. If this can be reproduced with the SampleWebSite's web service, a demonstration using that is also fine.

Problem creating binding for TextBox/AutoCompleteExtender and DropDownList/CascadingDropDo

I'm trying to use a textbox hooked up to an autocompleteextender todrive a DropDownList hooked up to a cascadingdropdown. I'm tryingto do this by creating a binding between the textbox and a hiddenDropDownList. The binding invokes a custom transform that updatesthe contents on the hidden dropdown with the text from the textbox whenthe textbox text changes. I am close, but I am running into someissues which I believe are due to the fact that my controls are insidean updatepanel. I'm getting the infamous Duplicate use of id...when the updatepanel reloads my textbox and autocompleteextender.

Here's the source. Can anyone offer any ideas? thanks...

if (AccountRadioButton.Checked) {AccountAutoCompleteExtender.TargetProperties[0].Enabled = true; }
else {
AccountAutoCompleteExtender.TargetProperties.Clear();
CascadingDropDown1.TargetProperties.Clear();
}

</htmlHave you tried FAQ #6?
I did read that, and I did try to apply the
var context = Sys.Application.getMarkupContext();

to the dispose method of the CascadingDropDownBehavior.js but it didn't seem to make a difference.

I'm stilling getting the Duplicate use for the AccountTextBox, CascadingDropDownProperties1 and AccountDropDownList...
I'm trying a slightly different approach, but I'm still running intosome issues. I'm trying to define the autocomplete behaviordeclaratively, instead of using an autocompleteextender. everything works well, but when the updatepanel refreshes, theautocomplete behavior doesn't seem to exist anymore.

i tried placing the xml-script inside the updatepanel, too, no difference.

heres the code to reproduce:

Problem Creating New Control toolkit

I have a problem that I am just about to give up on (so any help might save my sanity)

If I create a completely new Atlas project and use the default names I can create a new control add it to my test project and run it. However, if I right click and add a new item (of type Atlas control) no matter what I do to this (including inspecting the files line by line) I cannot get it to work. It fails with unrecognised tag and then my namespace and control when loading the page in IE. Now clearly it is not too much wrong as I can drag the control from the toolkit and it will check my tags to see if they are allowed. I can also use the properties i have created and they appear as correct extenders on the correct objects. It appears to be just the final link between the control and the browser.

When I debug I come back to the routine

Sys.TypeDescriptor.getType = function(tagPrefix, tagName) {
var type = null;
if (Sys.TypeDescriptor._registeredTags) {
var tagNameTable = Sys.TypeDescriptor._registeredTags[tagPrefix];
if (tagNameTable) {
type = tagNameTable[tagName];
}
}
debug.assert(type, String.format("Unrecognized tag {0}:{1}", tagPrefix, tagName));
return type;
}

The array_registeredTags contains (script, toolkit, atlascontroltoolkit) Should I see my namespace in here too?

I have gone through my code and created several projects and I cant figure it out.

Any help would be appreciated.

Thanks

Geoff

Hi Geoff,

You should check outFAQ Item #5. I'm guessing your script isn't an embedded resource.

Thanks,
Ted

problem in ajax website

hi

i am facing a problem in creating Ajax website.

When i am takingAjax enabled website option i am able to do everything fine.

But when i am taking a create Website option i am getting error . I have also includedScriptManager on the page which is required by most of the Ajax Controls to work properly.

Thanx in advance

Hi.

When you create an Ajax-enabled web site, the WEB.Config file created contains config section, HTTP handlers, HTTP modules all needed by AJAX.

One example is that the ScriptManager creates a call for javascript called ScriptResources.axd where axd is not known extension for your web-server
(unlike ASPX, ASMX, JS, ASHX etc.) The httpHandler section includes this extension and set it to be handled by AJAX extension (System.Web.Extensions.DLL file)

What you should do (especially when adding AJAX capability to an existing site) is to copy these additions to your web.config file from an "AJAX-Enabled"
web site. Then you won't e having these errors.

Problem on creating popup window with ajax

Hi ,

I want to create a popup window when i select ' add new' in dropdown list. I am using javascript for opening popup window and to bind dropdown list details im using AJAX. The problem here is popup window is not opening with ajax. Without ajax it is opening.Why? ( Iam using asp.net2.0 version)

Thanks.

Make sure you're using ScriptManager.RegisterStartupScript to register your popup script. Take a look here for an example: http://encosia.com/index.php/2007/06/19/the-easiest-way-to-break-aspnet-ajax-pages/


Hi,

I try to insert the bellow method insted of responce.write()

Page.ClientScript.RegisterClientScriptBlock("","","") in my code, But it showing an error of parameter 'type' I used type=me.gettype() method.

Any idea how to pass parameters?

Thanks,

Aswath.


Make sure you use the ScriptManager method, not the ClientScript one, if you want to use it in a partial postback.


Hi all,

I can able to create popup window as well as closing it autometically, But the problem is after closing popup window i want to display the value in parent window.Can anybody help me...?
