postback happens even when validators show error

Hi,

I am using updatepanel in my code. I give a picture of a part of my code.

Now i have a text box with some validators on it ( required field validator and regular expression validator).

I have a save button which saves the content of the text box .

The textbox is withing the update panel and the save button is outside the update panel.

Now when a wrong iput is entered , on tab out the validator shows the error messgae but on clicking th ebutton , a post back happens. in general case where a update panel is not used the button postback event doesnt happen until the validators return true.

Could you help me on this.

Regards,

Sama

any resolution to this problem yet?

this really needs to be fixed

I also have come across this problem. I have three validators on the footer row of a gridview which is in an UpdatePanel. I use the footer for insertion of new records. When I click 'Insert', the validators fire ok and I get the red asterisks and all but it still posts back. When I take the whole thing out of the UpdatePanel it works as it's supposed to, preventing the postback if no data is entered.

I am using the latest version of Atlas.

Has anyone a solution to this and is it going to be fixed in a future ctp?

Regards,

Andy.

I just investigated further and found the following strage behaviour:

When my page first loads, the gridview is populated with data. The footer is not visible on the gridview as I set ShowFooter() to false by default. There is a button at the bottom of the page "Add Item". This posts back and sets the ShowFooter() to true so that the insert line appears. In this scenario, when the user leaves the new text fields blank, the validator fires but the page still posts back - WRONG.

If I show the footer by default when the page loads, the validators fire correctly and prevent the postback - CORRECT.

Can anyone shed any light on this, I don't want to have my insert line shown by default.

Andy.

Prefetching Images

I am using the update panel, and the timer control to automatically change a person's profile text, and their photo (small 65x65 pixels). Everything works well so far, except the transition is not always smooth for the photo.

Before the images/photos become cached in the browser, the default broken (link-to-image) image shows up, before the relevant photo loads. After that image loads the first time, the transition is smooth.

Is there a way to prefetch these images (approximately 8) when the page loads?

Thanks,

Karls

The easiest way I know of is to create a .js function to preload the images. Something like:

function preload(){
var imageUrls = ["img1.jpg","img2.jpg","img3.jpg"];
var images = [];
for(var i=0;i<imageUrls.length;i++){
var image = new Image();
image.src = imageUrls[i];
images.push(image);
}
}

That you'd call that function during pageLoad(). Setting the 'src' of the image object should cause the browser to start downloading that image.

Nice,

I would like to try that, but I am having a problem converting this to VB. Can anyone convert this? Huh?

No, i'ts javascript.

Ahh, makes sense now.

Thanks.

Probably, I found a bug [NewLine in MultiLine TextBox]

Try to run this sample (enter to textbox some lines of text, and then click "Post"):

<%@dotnet.itags.org. Page Language="vb" AutoEventWireup="false" CodeBehind="WebForm1.aspx.vb" Inherits=".WebForm1" %><!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"> <div><asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager><asp:UpdatePanel ID="updPanel" ChildrenAsTriggers="true" runat="server"><ContentTemplate><asp:TextBox ID="txtTest" runat="server" TextMode="MultiLine" /><asp:Button ID="butTest" runat="server" Text="Post" /><br /><div style="border:solid 1px red; padding:20px;"><%=txtTest.Text.Replace(Environment.NewLine, "<br/>")%></div></ContentTemplate></asp:UpdatePanel> </div> </form></body></html>

I am using a release version of AST.NET AJAX.

What's the bug?

If you enter some lines of text in Firefox into textbox, and then post it to the server via AJAX, newline symbols will be damaged.

In Opera and IE all works fine.

"Firefox" would be the reason I didn't see the error initially. That is a pretty annoying bug.

I'm experiencing this exact same issue ... did you get it resolved?

Cheers!

Once I get this working I want to use the text box and extender in a itemtemplate in a gridview. Will that work?

Thanks for looking into this and all suggestions are welcome!

If not, you can try this:

I had trouble getting autocomplete in vb to work, and listed a few things I noticed there.

(Using in-page methods, no .asmx)

Jared,

Unfortunately even this doesnt get it to fire. I wonder if you could put together a quick sample that fires in VB to use as a template.

I posted my working code (simplified) on the thread i linked above...

FYI - I've been banging my head all day, and this worked for me. Is there something to be done to get around the need to remember to make this change? This was a pre-exising ASP.NET app to which I'm adding AJAX functionality.

Thanks!

but it not working properly

Both should work

ScriptManager.RegisterStartupScript(this, this.GetType(), "key", "<script language='Javascript'> alert('" + Message + "'); </script>", false);

ScriptManager.RegisterStartupScript(this, this.GetType(), "key", " alert('" + Message + "'); ", true);

here problem is not with sendPopupMessage()

actully after 1st validation it doesn't get submit

http://www.asp.net/AJAX/Documentation/Live/mref/O_T_System_Web_UI_ScriptManager_RegisterStartupScript.aspx

Better way you use validators..

But see for more details

Validation controls, which includes theBaseCompareValidator,BaseValidator,CompareValidator,CustomValidator,RangeValidator,RegularExpressionValidator,RequiredFieldValidator, andValidationSummary control are not compatible with UpdatePanel

See it here

http://weblogs.asp.net/scottgu/archive/2007/01/25/links-to-asp-net-ajax-1-0-resources-and-answers-to-some-common-questions.aspx

You can downlaod compatible ersion of validators from here
