I am using the RegularExpressionValidator control inside an Update panel. It works perfectly when I load the page the first time, but after a postback it doesn't work.
Let's say that after the first postback I include invalid characters in the textbox and run an new post back, I shows that the result is invalid...
I use VS2008 and asp.Net 3.5.
I have a problem with an amimated gif inside an UpdateProgress which is linked to an UpdatePanel. Basically the gif displays for a few seconds then justs stops and then a few seconds later the page displays. Reading some other posts it and putting in some debug info I can guess it is because the postback is returning a lot of markup, so it seems the postback has stopped and the gif freezes while the markup is being sent/being rendered. Is there anyway to keep the gif 'running' while all this markup is doing its thing?
View 3 RepliesI've got a problem that after i refresh an update panel all the HoverMenu's stop displaying, it still calls the WebMethod which returns valid html and the panel is displayed, but it content of the panel isn't displayed on the browser.
I've created a single page to demo this problem:
aspx
[Code]....
vb.net
[Code]....
The demo shows the hovermenu working until you click the update button then it stops showing the content, although it is still calling the WebMethod onhover.

This is not a big issue since it's quite easy to bypass by making a new project and copying everything on it, but it bothers me quite a bit that I can't figure out what it is about. In short my calendar and calendar extenders stop working suddenly. The last time this happened I made some changes to the pages code behind, then hit undo gazillion times to go back to the last save. After that I hit debug and lo and behold: calendar did not respond to any clicks and any text field with calendar extender did not show calendar on clicking them.
This happens in both IE8 and FireFox 3.6 and no amount or restart, rebuild and other such tricks do nothing. The only thing that I can figure out to solve the problem is either use a backup copy of a version that works or make a new project and then copy all the files from the not working into the new/earlier version and all works again. I was able to track down that this seems to relate somehow to AJAX as when I ran the debug I mention above, I got error messages on the web page saying something about AJAX. This however happened only once and I cant get it to happen again (and thus can not remember much about what it said).
Also when I debugged the event handling the calendar click, I get an error message like this: There is no source code available for the current location Then it opens a file search window trying to find some cs file inside the ajax control toolkit. However this only happened the first time I tried debugging the event and I can't remember more details about it. Now I just get that error message when debug exits the event.
So end analysis on my part: The ajax control tool kit gets knotted up all of a sudden for some mysterious reason and is tied to that particular project. Can anyone tell me what this could be about?

View 1 RepliesI understand that asp:link button is a control with JS that forces a postback. I have code that runs on OnClick in codebehind of this linkbutton. I placed a counter (with the aid of viewstate) within this code to count the number of times the event fires. The first time it fires the code runs, but as the process is a little long, when the second postback fires it stops the first running in its tracks, so the execution is incomplete. I have googled this issue, and found that some say an img tag with out a complete src address forces a postback, I examined my source and I have no bad src's. The link button is on a complicated ascx page with many controls etc, so I cant post it here. Is there a way to CANCEL the link button immediately OnClick so it only runs once?
View 2 RepliesI want to load a popup when a user clicks a button. The buttons are images located inside a tabpanel. The first time the page is loaded the helpEvents DOES display the popup and the 'click' popup. Then I navigate to Tabpanel tab2, and the helpTickets button doesnt work (doesnt even display the 'click' popup) Then I navigate back to Tabpanel tpEventDetails, and the helpEvents button doesnt work anymore either(and also doesnt even display the 'click' popup anymore) So I think something gets lost in the updatepanel on callback...but what? and how to fix it?

I have a text box that is intended for an Email address. I am using a Regular eExppression validation control to validate the email address. When I place the following lines of code in a blank web Form, the validator works properly.
<asp:TextBox ID="Email" runat="server" CssClass="DefaultTextBox TextboxWidth" MaxLength="80"></asp:TextBox>
<asp:RegularExpressionValidator ID="valEmail" runat="server" ControlToValidate="Email" ErrorMessage="Invalid Email address" SetFocusOnError="True" ToolTip="Invalid Email address" ValidationExpression="w+([-+.']w+)*@w+([-.]w+)*.w+([-.]w+)*">*</asp:RegularExpressionValidator`>
However, when I use the validation control within a CreateUserWizard control, it does not seem to fire but other validation controls (Required and Custom validators) do fire, but not the regular expression validator above for validating the address. The following is my complete web page. The two controls above appear unchanged in the code below, they are simply embedded into the wizard control mentioned.

When I click the button to open the modal popup it shows the popup but then continues and forces a postback causing the page to reload and the modal popup to be hidden again.Here is the markup for the control:
<asp:Button id="LoginOpenButton" runat="server" Text="Login"/>
<asp:Panel ID="ContentPanel" runat="server" CssClass="modalPopup">
<fieldset> [code]....
My script manager has no properties other than the id and runat set.
In my default.aspx page I have a PlaceHolder control within an UpdatePanel. In this placeholder control I will dynamically load a web user control, which is just a form with a submit button. On this user control, I have the form within an update panel and I have the "Submit" button's Click Event added to the triggers.
When I submit the form, the UpdatePanel on the web user control nor the update panel on the default.aspx page are capturing the post back, thus causing a full post back which refreshes my page.
how to capture this post so its rendered in Ajax and not a full post back?

I am trying to use a RegularExpressionValidator for email ID text box. Everything works fine till I add an AJAX TextBoxWatermarkExtender for the same text box. I have given the WatermarkText="Email" for the text box. When I push the submit button, the RegularExpressionValidator fires and says Invalid Email ID. When I clear the same text box, no issues and the records are saved.I strongly suspect that the RegularExpressionValidator is taking the text of the watermark, ie "Email" as an invalid email ID. To test this I gave the text as "someone@website.com" for the TextBoxWatermarkExtender and it did not fire the RegularExpressionValidator.

I'm using ASP.Net 2008 and C# and Ajax. I have wired up my ajax updatepanel to update the buttons within them in the gridview control's RowCommand event. However, at the end of this event, I call the Response.Redirect(commandArgs[2]); to open either Word or Adobe docs that user selected. And this line of code stops my Ajax updatepnael to update my 2 buttons' enabled properties. I thought maybe there is another way to open docs that won't interfer with my Ajax updatepanel and what will that be?

This should create a left aligned label that is 100px wide, then the list should show next to it. What happens is that the width is ignored and the list is right next to the label text. If I remove the "AssociatedControlID" parameter it works fine. CSS has no effect on the label width, even using the !Important tag.
