Can't Submit Form Unless Remove ASP .NET Server-Side Form


Something has been driving me nuts about a project  I'm working on.  Long story short: I have a small form that submits a user's name, email address, and a few hidden fields to an external vendor's website.  It works-but ONLY if I remove the "outer" ASP .NET server-side form!  If I don't do that, the page from which I'm submitting the form simply refreshes itself, and the form never gets submitted.


Cannot Remove Form Template

I have tried everything! In Central Admin I tried to upload a new version to an existing template (which I have litterally done over 300 times for this particular form.) Something errored along the way and the feature folder in c:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\FEATURES was removed from the front end server and I don't have a copy. So when I told the form to delete in Manage Form Templates it stuck in Deleting. Everyone says use execadmsvcjobs, so I did, but nothing. I then tried all the stops.. removeformtemplate, removesolution, uninstallfeature (using the feature id obtained from a c# app i got code for on another blog. Now it appears as though the feature is uninstalled but the form remains in the list. All of the above stsadm commands completed successfully by the way. If I tell the form to delete again from Manage Form Templates, it creates a timer job in timer job definitions, but that jobs disappears on its own without any errors in the event veiwer and the form remains in the list. The only funtions I can't run are uploading the form or upgrading the form, all other stsadm commands complete successfully, but the form remains in the list in Central Admin, Manage Form Templates. Please Help!

Where do Custom List Forms get their form element ordering from?

I have been pulling my hair out trying to figure out where Designer gets is column/field ordering from when you insert a custom list form onto a page.  The order (and ever what's rendered) is not what my content type is.  Can anyone please tell me where it gets its order from, or do I just have to be resigned to re-ordering it in html view?  I am trying to create a "perfect" list template so that it can be used repeatedly and always be in the same order.
There are no mistakes; every result tells you something of value about what your are trying to accomplish.

jQuery example that uses the FORM element - how is ASP.NET?

        <form id="formID" method="post" action="">
                    <input value="" class="validate[required] text-input" type="text" name="req" id="req" />

JavaScript, passing reference to a form element question


I have a simple audio player that is controlled with JavaScript initiated by ASP.NET imagebuttons. When the user clicks on the "play" button the image is switched out for a different button image to make it "light up" while playing; when the player is finished the original image is put back so the button appears dark again. Originally, I was doing this by hardcoding in the client element ids for the image buttons ("ctl00_Middle_Voice1_LoginView1_StartLoad"), but that restricted where I could use the control. So, I have switched it so that in the ImageButton OnClientClick function I pass in 'this' and then refer to that control in the function to change the image source.

This works fine for the initial function called by OnClientClick (Play), but that function in turn calls a second function to determine the timing, control the progress bar, and whether or not the player is done playing yet and if so to swap back the original image. In that second function (Timing), I get a null object reference if I try to pass the element in again as an argument.

I have tried getting the id of the element and passing that instead (and then locating the element from the second function with getElementByID), but get the same error.

How to use getElementById to get the elements in a form

There are many ways of accessing form elements, of which the easiest is by using the cross-browser W3C DOM document.getElementById method. Before we learn more about this method, it would be useful to know something about the Document Object Model (DOM), the concept of HTML nodes or elements, and the concept of containers.

Each time you load an HTML page, the web browser generates an internal representation of the page in the form of an inverted tree structure. Let us look at a simple form. We will use this form later to demonstrate the use of the getElementById method.

UpdatePanel is not a known element - message when upgrading to 1.0 ajax


It worked on one of my old pages.  I change the web.config, renamed all the <asp.

On some aspx page it doesn't recognize the updatepanel.  It only does on one page.  If I create a new aspx page with a different name - then it works.

Should I just create a new web project ajax - then copy all my code into there?  Or is there a way to get those old pages to recognize the new ajax controls?

		if (inputs[i].parentNode.getElementsByTagName("span")[0]) {
			// the span exists!  on focus, show the hint
			inputs[i].onfocus = function () {
				this.parentNode.getElementsByTagName("span")[0].style.display = "inline";
			// when the cursor moves away from the field, hide the hint
			inputs[i].onblur = function () {
