I have several buttons on a page, but have assigned some validators and AJAX validator callout extenders to one button in particular. However, the validator callout extenders seem to be firing even if I press a different button. I thought this was the point of setting a TargetControlID (for the valiator callout extender) and a ControlToValidate for the validator itself!
[Code]....
I have a popup which displays two drop down lists, name it : ddl1 and ddl2 and for both of these i have mandatory validation, so if any of these is not provided, callout message will come on submit click.
ddl2 will get populated once any value from ddl1 is selected(selected change event).
Now problem is, suppose without entering any value, i click submit, it is showing select value for ddl1, and when i select a value, the selected change event for ddl1 is not firing, and so ddl2 is not getting loaded.
Selected change event for ddl1 is firing in normal condition, if the callout message is not there.
but after the callout message, if i try to select a value, the event is not firing.
For some reaon the black outline isn't appearing around my Validator Callout Extender's callout box. I don't have a css class set. It should display a yellow callout with a black outline. Like on the sample page:
[URL]
It shows the yellow call out with the black outline around the pointed part but not the main box.
If I use the extenders (for example mask edit) in place of some of the built in validators such as RegularExpressionValidator for exampe, will Page.Validate() still be called automatically and perform server side validation using the extenders?
View 2 RepliesI hava an aspx page with a couple of tables and an UpdatePanel on top of the page. Everything on the page works fine until I show (from code-behind) the UpdatePanel (via ModalPopupExtender). The modal works OK after showing, but the problem is that when I close/hide it (using CancelControlID or a custom button with code behind) some control on the page stop firing events.
More exactly one Button and RowCommand on a GridView (both are NOT part of the UpdatePanel).
Here's the UpdatePanel code:
[Code]....
After this code is all the rest of the aspx page - including the Button and RowCommand that stop firing after showing and closing the update panel.
Where's the error?
I have a TabContainer with multiple Tabs. For some of the Tab's Button OnClick events work and on others they do not. I have dropdowns etc in each of these tabs and their SelectedIndex events fire. Just some of the button events don't fire. If I move the HTML and codebehind to a blank page for any of the Panels that don't work, the buttons work as expected.

I am CustomValidator to vlidate some data.There are 3 static buttons and some dynamically creating buttons in that page. I just need to check validation when I press the save button.For all other button click I do not want to call the validation. How do I tell that in the Validation function?
<asp:CustomValidator ID="CustomValidator1" runat="server"
ErrorMessage="CustomValidator" ControlToValidate="DropDownList1"
ClientValidationFunction="MyCustomValidation" ></asp:CustomValidator>
function MyCustomValidation(objSource, objArgs)
{
/Proceed if the control pressed is cmdSave button.
var Specialty = document.getElementById("DropDownList1").options[document.getElementById("DropDownList1").selectedIndex].text;
if (Specialty == "Select an option")
{
objArgs.IsValid = false;
}
else
{
objArgs.IsValid = true;
}

View 2 RepliesI download Ajax control toolkit to use it in my website. I readed "Using AJAX Control Toolkit Controls and Control Extenders (C#)" to known how i can use them. In the Control extenders when i added a button to My Webpage, How can i find "Add Extender task option" ? because i should click on it to set the options.The Add Extender task option is not appear...! I was reading the page [URL] that i encountered this problem.
View 4 RepliesI have a textbox control that I need to limit the value entered into it, so used the RangeValidator control, and added the extender to show the error.This is my code, and for years 0 to 5, and 10 and above it gives no error (as expected) but for 4,5,6,7,8 and 9 I get the callout extender displaying! I can't see what I have done wrong, or is this a bug/issue with one/both of the controls? The only work around to use is to set it to 05, 06 etc, but this is not ideal.

The version of the toolkit dll i am using is for 3.5, so 3.0.30930.28736.
After the validators were put into a table, their appearance was completely messed up. The worst is the disappearance of the background. The background has been restored by setting a default skin for all ValidatorCalloutExtenders, but now they are just simple rectangles containing the exclamation mark and the error message adjacent to the target control. The callout look is gone.
View 1 RepliesI started up a new 3.5 Asp.Net Website using VS2008.
No Asp.Net Ajax enabled Website or Ajax toolkit enabled templates present.

Add scriptmanager to the page.
Add a standard control. I tried each one of the following one at a time: Button, Textbox, Panel.
I drag and extender to the window and (/) can't do!
I cannot drag and drop any extenders to my page.
I add reference to the ajaxtoolkit dll that is the bin directory. Does nothing.
I add a Register declaration on the page. Does nothing.
I didn't touch the code behind. Everything there is default including the using statements.

View 3 Repliesnow the task is to show a popup window, much like the standard Windows login panel, to warn the user that caps lock is on. I've used a ValidatorCalloutExtender alongside other controls in my site, but can't figure out how to use the test for whether the capslock is on:

to then show a callout style display. I'd prefer it only pop up when the user enter's the asp:textbox control, but can't figure out if a callout is possible in this way.
I have an algorithm but don't know if this is the correct way. like mentioned, i would like my label to appear after the user clicks on 4 different buttons, each button with auto post back.

i have developed a web page using asp.net and ajax.
when i view web page in browser its working, ajax extenders are not working..
but while running on IIS server, they are working.
textboxwatermark extender, validationcallout extender are not working; and when i click on submit button its not validating the text boxes.
I am developing a web application that needs to retrieve, display and write data to an SQL database. I'm trying to use AJAX and Javascripts in order to populate fields, lists and data, and to have button and calendar controls on the page that can update the page without refreshing and losing the data page. Therefore, it's necessary that I find ways to doing as much as possible client-side, without page refreshes.
Now, for security purposes, I've heard that there's a method for retrieving a copy of all relevant data from SQL at loading time, keeping a copy of it, perhaps on a separate page, and send-retrieve-display this data on my page, and then, at Submission time, write this data back to the Server. This is to minimize hits to the Server and to preserve data integrity. I've heard that doing this is called using an Extender, but we can't find examples of how this works so far.
I'm trying to add a modal popup extender to a site I'm working on, which I've done before, but its not working. The markup below is inside an update panel in my site and the function is in the code file. how I can get this to work? I've tried re-downloading the AJAX dll and replacing it but that didn't change anything and some of the controlsare working (like the slideshow extender but not the hovermenu extender or parts of the html editor control, both of which I also need to use) which leads me to believe my web.config is correct.

I'm trying to create a button dynamically with event by original button. The original button's click event response creates a button. The new button has a click event attached with a test message.What I have to do is onclick change background color of dynamically created button and grab id value to delete when button delete is clicked. Unfortunately, when I click the dynamically attached button, nothing happens.
