Extenders not visible?

Hello. I'm new to the Microsoft developer environment...very new.

I installed Visual Web Developer 2008 as well as the AJAX Control Toolkit (3.5 with source). I installed the Toolkit and have all of the available mods in a separate tab. I added the script manager above the default form tag. If I drag and drop a standard button onto the platform I am not getting the arrow icon to view available extensions.

Is there something obvious I am missing?

Hi there,

The script manager should be placed just after the form tag, not above form tag. Please correct it.

Moved the script manager below the form tag. Still no luck. Any other suggestions?

Hi, got the same issue. The Toolkit is installed but when I mark a button, I get no "Button task" where I can select Extenders. I run VS 2008 Prof.

Sure :-) Thanks

Extenders NOT Doing Anything?

I've just reviewed "#36 – How Do I: Use the ASP.NET AJAX MaskEdit Controls?". I ran the finished sample code (as downloaded) on VWD 2005 EE and it all works "as advertised" – all of the functionality is definitely there.

HOWEVER, when I copied the project file up to TWO different hosting services (both equipped with the current "AjaxControlTookit.dll" [and dll.refresh] and ".pdb" files in a "/Bin" directory at the root level of the logical "wwwroot" the application starts without error but then nothing really IS "extended" in the three sample Textbox controls. HUH? I emphasize that this happens on TWO separate hosting services (one if GoDaddy which has been shown to work with ASP.NET 2 and the other is on UltimaHosts.net which has also run 'normal' ASP.NET 2 applications).

I fear I'm missing something fundamental here. Any ideas?

Does the bin folder also contain the 2 dll's for the ajax core?

System.Web.Extensions.dll

System.Web.Extensions.Design.dll

Hi, Wim, and thanks for the attempt at guidance.

I'm unclear about whether you mean a "/Bin" directory beneath each Application/Project or at the root of the web site (which is what I have). (It would seem awfully space-consuming to have to have it in EACH Application/Project, right?)

Here's what I've got:

SO WHERE'S the handy-dandy goof-proof "guide to deploying ASP.NET/AJAX-ified applications on your Server" ?

The devil seems to be in the details, as usual!

mahalo for any guidance ... :) KevInKauai

P.S. The results are identical in the following browsers: FireFox 2.0, IE 70.5730.11 and Safari PC 3.0 (522.11.3).

Hi,

You'd better install the Ajax extension on the server first. It can be downloaded here: http://ajax.asp.net/downloads/default.aspx?tabid=47

Hi, Raymond - -

Do the screen captures above not show that the "required" libraries are there? According to my download directory, I downloaded "ASPAJAXExtSetup.msi" (around May 15) and ran into, then used what I assumed are the required items (as indicated in the screen shots).

I don't think you're telling me to download this again "just for fun", are you?

Mahalo ... :) KevInKauai

Hey,

Ok, A website has a bin directory: For example: c:\Inetpub\wwwroot\MyWebSite\bin
The above tells me I have a website called MyWebSite and it has a bin-folder.

I don't think that MyWebSite can use a bin folder located here: c:\Inetpub\wwwroot\bin
AND that is just what your pictures tell me. So the bin folder should be inside the WebSite directory.

If you want to use dll's for more applications and you don't want to copy the dll's to every bin of every website that uses them, you should install those dlls in the GAC (Global Assembly Cache).

Note that the dll's you want to use in serveral applications should be installed in the GAC of the WebServer.

Also note that the installation of dll's in the GAC is best done by using the GACUTIL.EXE utility which can be started from command line.

Hope this helps!
Wim

The point of my suggestion is that it's not sufficient to deploy it by simply putting it in the bin folder. Because some of the operations performed by the AJAX extension require full trust permission. To install it will installer will add it into GAC automatically and run with full trust permission.

You can try Wim's suggestion to install it into GAC manually.

You may also tryconfiguringyou web application to run in full trust mode in web.config.

Hey Raymond,

Ok, this is a bit off topic, but on my webserver, their is NO Ajax, nor the toolkit installed, and just by putting the 2 ajax dll's and the toolkit dll in the binfolder of my website on the webserver, all the ajax and toolkit functionallity works!

Greetz,
Wim

Hi, Wim - -

Thanks for your pointers and perhaps I should have made it clearer that I'm in a "shared hosting" situation -- where I do not control things like whatever the "GAC" is. According to their notes on AJAX, they have installed "what you need" there. It's the add-on stuff that wants a proper home. I had assumed that ONE /Bin directory at the root of my website (which has old-time FrontPage things which want to be calling out to new-style ASP/AJAX application pages) would suffice.

Are you saying that each application sub-directory is going to need a /Bin with extra copies of these various AJAX components?

If anyone knows where the CLEAR and SIMPLE "How to use AJAX in a Shared Hosting Environment" installation guide is, I'd sure appreciate a push in that direction!

KevInKauai:

Hi,

For as far as I know this is going to be the procedure. If someone else knows a way to create a central storage for application-wide-dll's, please let us know (it has to be possible :) )

Normally the GAC offers a solution to store application wide dll's in one place. But for shared hosting where you don't have full control over the webserver that isn't so easy.

Extenders inside templateColumn in RC1

Hi, I have just installed the new RC1

I have a gridview that contains a template column, with 2 imageButtons inside it (Basically Edit Item and Delete Item) and a confirmButtonExtender linked on the delete image button. Everything was working well in Beta 2, but in RC1, in design time, it does not render the gridview, saying that a scriptmanger is required and must exist before any control on the page... It works great at runtime, but it is quite annoying at design time...

Will this be fixed in a future release of the control toolkit?

Thanks!

Yes, I am experiencing the same issue as you but with a PopupControlExtender inside a FormView on a ContentPage.

Please reply with acomplete, simple, self-contained sample page that demonstrates the problem so that we can investigate the specific behavior you're seeing. Thank you!

Hi David, This is a very simple page that demonstrates the error I am getting (only at design time, by the way). I have started a new project using the template provided by Ajax (Ajax Enabled web application), and just dragged a gridview, and edited the templates..

Thanks!

This seems like an atlas issue and not a toolkit issue. The script manager is not being detected at design time. Could you try the asp.net ajax forum?

http://forums.asp.net/1007/ShowForum.aspx

I tested to define a asp:TemplateField template of a asp:GridView in Ajax RC 1.0 and get the similar problem saying "There was error rendering the control.The control with ID 'ConfirmButtonExtender1' requires a ScriptManager on the page.The ScriptManager must appear before any controls that need it". Wish this issue will be resolved in ASP.NET AJAX RTM.

Hi,

I too was experiencing this issue, however as a workaround i have put the extender into a usercontrol, and then put that into the template column. This way the gridview looks ok at design time, and it all compiles properly at runtime too.

Hope this little snippet of info is useful to someone else who has been searching for this issue.

Cheers,
Rich.

Extenders inside template column of a gridview

Extenders in Composite/Custom Controls

I've created composite or custom controls with ajaxcontrol extenders, example is a textbox with FilteredTextBoxExtender. So far I am able to make the new control work.

My problem is how to expose the extender's properties that are of enumeration type like the FilterType where you can assign more than one value in comma delimited format (ex. "Number, Custom" or "UppercaseLetters, Custom")

I think it is not possible to directly access the childcontrol's (the extender) properties from the class, so how do I create a property that do the same as the extender's property?

I looked into the code of the AjaxControlToolkit, in C# its

[ExtenderControlProperty]

[DefaultValue(FilterTypes.Custom)]

publicFilterTypes FilterType

{

get {return GetPropertyValue<FilterTypes>("FilterType",FilterTypes.Custom); }set { SetPropertyValue<FilterTypes>("FilterType",value); }

}

I need a code for vb.net, I also tried converting the code using some online conversion tool but the result is not working. Here's the result:

<ExtenderControlProperty()> _

<DefaultValue(FilterTypes.[Custom])> _

PublicProperty FilterType()As FilterTypes

Get

Return GetPropertyValue(Of FilterTypes)("FilterType", FilterTypes.[Custom])

EndGet

Set(ByVal valueAs FilterTypes)

SetPropertyValue(Of FilterTypes)("FilterType", value)

EndSet

EndProperty

Any help is appreciated.

Solved.

Sometimes you just need to take a break to clear your mind. I was making my code complicated. :)

Extenders for controls inside TabContainer/TabPanel

Hi,

I have a textbox control (ID="'PasswordTxtBox' ") inside TabPanel and I am trying to attach watermark extender to it. In design mode TargetControlID for watermark extender does not appear and when I manually write it in the markup I get run time error saying

The TargetControlID of 'TextBoxWatermarkExtender1' is not valid. A control with ID 'PasswordTxtBox' could not be found

Please guide.

Regards & thanks

Kapil

My bad. I was _not_ putting the extender control in the contenttemplate of tabpanel.

Extenders briefly appearing on a page load

Hi there

I am using the modalpopup and calender extenders from the toolkit in my ASP.NET code.

The page they are on is a content page (I am using master pages).

They both work. However, when the page initially loads the extender(happens on both) flickers on the screen and then hides itself!?!?!

Does anyone have any ideas?

Many thanks

Mike

Hi Mike,

It seems a full postback is occurring according to your description. Please make sure the targetControlid is properly set the button that triggers a full postback.

Hi there

Thanks for the help. I have set the control IDs correctly.

The calender popup I have working, I had to set the visibility to false in the style.

However, for the modal popup I tried this and it doesn't show up at all.

Any more ideas I can try to stop the modal popup from flickering initially??

Cheers

Mike

Try setting the style as... style="display: none;"

Can you post a stripped sample?

Hi

I tried that also and it stops my popup from being displayed at all. (However, on a side note, when I do do this, as well as not showing my poopup it seems to keep adding "invisible" stuff to the side of my page, makes my scroll bars appear and the page keeps getting wider and wider!!! Very very strange and freaky!!!)

The code for my modalpopup is:

 <asp:Button runat="server" ID="testbut" text="popup test" OnClick="testbut_Click" CssClass="hiddenbutton"/> <asp:Panel ID="Panel1" runat="server"> <asp:Panel ID="Panel3" runat="server" CssClass="modalPopup"> <div> <p class="title">AudioPC Navigator</p> <br /> <p> AudioPC Navigator will launch each Audiosoft component into a new window, but supports tabbed browsing if your browser is configured to do so. </p> <br /> <p> For details on how to set your system to tabbed browsing <a onclick="help('TabbedBrowsing');return false;">click here</a> </p> <br /> <p> <input type="checkbox" name="check" id="InitialHelpCheckbox" /> <label for="InitialHelpCheckbox" class="sampleStyleC" style="padding: 3px;">Do not show this message again</label> </p> <br /> <p style="text-align: center;"> <asp:Button ID="OkButton" runat="server" Text="OK" /> </p> </div> </asp:Panel> </asp:Panel> <ajaxToolkit:ModalPopupExtender ID="InitialHelpModalPopup" runat="server" PopupControlID="Panel1" BackgroundCssClass="modalBackground" OkControlID="OkButton" OnOkScript="onOk()" DropShadow="true" Drag="true" PopupDragHandleControlID="Panel3" TargetControlID="testbut"/>

<asp:Button runat="server" ID="testbut" text="popup test" OnClick="testbut_Click" CssClass="hiddenbutton"/>

<asp:Panel ID="Panel1" runat="server">
<asp:Panel ID="Panel3" runat="server" CssClass="modalPopup">
<div>
<p class="title">AudioPC Navigator</p>
<br />
<p>
AudioPC Navigator will launch each Audiosoft component into a new window, but supports tabbed browsing if your browser is configured to do so.
</p>
<br />
<p>

<p>

</p>
<br />
<p style="text-align: center;">
<asp:Button ID="OkButton" runat="server" Text="OK" />

</asp:Panel>

And the style for the popup is:

.modalPopup {

border-width:1px;
border-style:solid;
border-color:Black;
padding:1px;
width:350px;
}
