An OnClick event doesn't fire up when a button is clicked in a Tab Panel in a Tab Container in an AJAX Web Form

Hello Post:

I would like to enclose the following code so you can analize what is going on:


" style="vertical-align:top;"> ">

" CausesValidation="False" onclick="btnOK_Caller_Click" /> " CausesValidation="False" onclick="btnCancel_Caller_Click" /> " style="vertical-align:top;"> "> " WatermarkCssClass="watermarked" Enabled="True"> ">*
"/> " WatermarkCssClass="watermarked" Enabled="True"> ">*
" />
" />
" />
" />
" >
" > " WatermarkCssClass="watermarked" Enabled="True" />
" Display="None" MaximumValue="9999999999999999999" MinimumValue="0">* " Display="None">*

" OnClick="btnOk_Caller_Data_Click" /> " CausesValidation="False" OnClick="btnCancel_Caller_Data_Click"/> " style="vertical-align:top;"> ">  

" /> " /> " style="vertical-align:top;">   " WatermarkCssClass="watermarked"> " Display="None">*
  " WatermarkCssClass="watermarked"> " Display="None">*

As you can see, this code is supposed to process an instruction in the code behind file and, if everything is fine, keep moving .... " OnClick="btnOk_Caller_Data_Click" /> The thing is that this even doesn't fire. If I set the CausesValidation property to "False", the processing is fired. For some reason, it seems that the Validation is stalling my processing. Any hints? Thank you

If you are using UpdatePanel then try to define trigger

Controls that trigger an UpdatePanel control to refresh are registered with the ScriptManager control on the page. This occurs automatically for the child controls in an UpdatePanel control's ContentTemplate. You can specify triggers declaratively using the Triggers collection of an UpdatePanel control. Additionally, you can programmatically identify triggers and cause an UpdatePanel control to refresh in the server code of your page.

In cases where a trigger control is not available at design time, you can register the control as a trigger by using the RegisterAsyncPostBackControl(Control) method of the ScriptManager control. Controls that are programmatically identified as triggers must be registered whenever a postback occurs.

Hi everyone, I'm using .Net 2.0, vs2005, and ajax I'm having  an issue with a button that doesn't fire the OnClick event until the second time it is pressed.

Troubleshoot Web Service; Ajax AutoComplete events do not appear to not fire; Ajax web service appears to not work. .NET
Folks, I had the situation that Ajax AutoComplete events in the web service did not fire after I copied a project out of a folder, renamed it and moved it to a server. The fix was hard to find but easy to solve. I had some web service modules in an ASMX file that provided AutoComplete entries -- i.e., after the user keys in 2 or 3 characters, the list of possible entries with those leading characters is displayed for the user to select. To solve the problem, look at the web service's directive, not the code-behind or the ASMX designer.  Do a right-mouse-click...

Dynamically loaded user control with a button doesn't fire its button click event?
I have a datagrid, in which one of the columns is 'button' column called 'Send Email'.

Is it a better architecture to call a web service that performs the AJAX functionality? In a way doesn't this kind of defeat the wholepurpose of AJAX, is to use web services for AJAX.

Problem with AJAX clicking form buttons when it shouldn't be
This problem is a bit hard to explain so I've provided a small 100kb video of my problem. In the video you will notice that whenever I select a radio button the submit button is also clicked. You can tell this because the submit button has a black border for a split second when I click the radio button. Normally I wouldn't care but for the application I am working on I have code that relies on that button and the code is activating every time I click on a radio button.Link to video: there anything I can do so the AJAX do...

OnClick event on button doesn't seem to fire
I have the following: <asp:Button ID="Submit" OnClick="RunMe" Text="Run Me" runat="server" /> inside of a form. In codebehind I have the method RunMe, which just prints to the screen for testing purposes. When I click the RunMe button, the RunMe method is not executed. In fact, the page just reloads. It does not postback, either - it is like I typed the page into the browser and hit enter. Or if I hit refresh. Did I do something obviously wrong? You missed an equals sign when declaring your OnClick handler: <asp:button id="Submit" onclick="RunMe" text="Run Me" runat="server" />Thanks, EdMicrosoft MVP - ASP/ASP.NET Does your RunMe method have "Handles RunMe.Click" at the end? e.g. Protected Sub RunMe(somargs) Handles RunMe.ClickBrucePlease remember to click "Mark as Answer" on the posts that helped solve your issue.  is runme a javascript function? i'm presuming it is, that being the case you it should look like onclick="runme()" where runme is the name of your javascript function.Regards,Tony.Please mark this post as Answered if my comment helped you, thanks.

Ajax Tab Container selected tab
I have a 2005 app using an ajax tab container with tabs inside it. I want the user to be able to click on a button as one way to get to the next tab.  How do i display the next tab when the user clicks on a button. Also, can I disable tabs where the user has not filled in information yet for the tab?  IE:  the user needs to fill in details on each tab page and the details are needed in sequence.   thanks. Hi! On the first one, you could put your TabContainer inside an UpdatePanel, set your button as a trigger and on the ButtonClick event set the TabContainer.ActiveTabIndex.  On the second one, you could use the same approach, using some kind of validation, catching the OnTextChangedEvent, so when you find that the user had filled up all the necessary information, you could enable a new TabPanel.There are a couple of catchs here: Clicking on a TabPanel doesn't fire a post back to the server and I think that disabling a TabPanel won't just make it inactive, it will make it invisible. I'm not sure on the later, just give it a try. Cherrs,Juan BarreraMCTSPlease remember to click "Mark as Answer" on this post if it helped you....
