Maintain Scroll Position After Client-side Validation Fails?
Jun 29, 2010
I've got an ASP.NET webform with asp:TextBox and asp:RequiredFieldValidator at the bottom of the page. If client side validation fails on form submit - the page scrolls all the way up.
I'd like to maintain the scroll position on failed client-side validation.
I'm using the ASP.NET login control and I'm displaying a jQuery throbber when the submit button is clicked. This works fine, but the throbber is visible if client side validation fails and the button is invisible, so the user cannot re-submit the form. How do I hide the throbber if client side validation fails?
how can I get back to the same position of a page on postback. It always seems to get to the top of the page I've tried using ' maintainScrollPositionOnPostBack = "true" ' but its not working.
i used the dropdown list in user control.when i select the dropdownlist that scroll bar went to top.how can i maintain the scroll bar position in that situation?
I want to maintain the scroll position of a page. So I try to get the page cordinates and set the position on the page load (actually I've a postback in my page) using JS as follows. What I've done is on a client click on an image get the page cordinates and keep in a hidden field.
[Code]....
GetScollerPosition function invoke in an image click event. But it's not work as I expected, the SetScrollPostion always find the value of hidden fields as zero.
I have got the gridview to populate from my own datatable and there are quite a few results in the table. As a result I have a scroll bar on my gridview.
If there is only a few results the gridview works perfectly, however; When I select a row further down in the scroll it selects and highlights but refreshes the view to the top of the gridview.
I have some collapse able anhcor link tags on a page that reveal some text when clicked on i.e.: [+] Topic This is all done in javascript client side. I would like to maintain the users scroll position on the page when these links are clicked on. They dont cause a postback as iv mentioned above its client side javascript.
I have an asp.net c# web forms application with a formview. When I click "Edit" on the formview, I have set the focus to a textbox. This works just fine.
The problem is that the textbox is at the bottom of the screen. I want to set focus on the textbox and also have it move (scroll) to the top of the screen. This will allow the user to see the entire form, withhout having to scroll initially.
How can I modify the code to set the textbox (pol_numTextBox) at the top of the page on DataBound once the focus is set?
I have a async file upload control and I am doing client side validation for Image."OnClientuploadstarted" I am doing the client side validation.My validation is working fine but my problem is that the file upload control text box goes green (i.e file is loaded on the server) even if the validation fails which is I dont want.What I want is when the client side validation fails the file does not gets loaded on the server and the Async file upload textbox does not goes green.I have goggled but have not found a suitable solution.
I have a gridview that putted in ASP.NET Panel. both of panel and Gridview are in an UpdatePanel. there is a column in gridview that Causes Partial PostBacks. i want to Maintain Panel Scroll position on those postbacks.
I have an asp.net listbox with 15 rows and auto postback when the selected item is changed. This works as expected but, when the form is re-loaded, IE scrolls the list so that the last selected item is now the top visible item in the list. This produces a confusing/jumpy effect for the users and makes the listbox more difficult to use than it needs to be.
Is there any way to get the list scroll position to stay as it was before the postback? i.e, if I select an item from the middle of the listbox, the listbox is scrolled to the same point after postback.
I am using usercontrol to populate a web part. The user control consists of ajax tab and in it there is another user control which is a gridview. I add the tabs - My top level usercontrol to the web part. Now when user makes a selection in the gridview (this does a postback) I would like to maintain the scroll position. I tried adding - this.Page.MaintainScrollPositon = true to the page load event of my tabs (priamary) user control. But it does not seem to work. Is there any other way to maintain position in a web part.

I have serveral long ASP.Net pages, I use RequiredFieldValidator, RegularExpressionValidator and ValidatorCalloutExtender for validations, Submit buttons are typically at the bottom of the pages. The problem I have: if the errors happen at the top portion of the page when Submit buttons are clicked, the forms do not scroll to the top automatically, the users have to scroll up to see the ValidatorCalloutExtender.
I am using ASP.NET's server-side validation. In the page_load event I'm calling Page.Validate(), and if Page.IsValid is not true I'm then polling the controls to figure out which ones are not valid, and then determining what actions to take.It would be much easier if each control would raise an event as validation fails, allowing me to take action for that particular control. I'm very much a naive programmer when it comes to validation, but is there a way to extend these controls so that a validation error raises an event?
want to know that can we validate a control which is out side a form element in asp.net(server side validation)and outside a form element in html(client side validation) let's take a closer look
I'm interested in identifying a means to verify the server-side validation is performing as expected, but need to bypass the client-side validation being done using ASP.NET validation controls. To test this, I've tried using the form Poster add-on to Firefox that allowed me to get/modify the page contents and post it, but the .NET framework interpreted the submission as harmful and threw an application error ("A potentially dangerous Request.Form value was detected from the client").I've created a WinForm that includes a WebBrowser control and I'm able to manipulate the contents of the web page and invoke the button click, but am interested in seeing how to allow a postback with invalid input values. I don't want to assume the server-side validation works (even though I do check if Page.IsValid on the server on postback).This submits the web form in the WebBrowseer control and the expected client-side validation fires: extendedWebBrowser1.Document.GetElementById(formButtonName).InvokeMember("click"); This is how I've manipulated some of the page contents (this just prevents submission): mshtml.IHTMLDocument2 doc = extendedWebBrowser1.Document.DomDocument as mshtml.IHTMLDocument2; string html = doc.body.innerHTML; html.Replace("Page_ValidationActive = false", "Page_ValidationActive = true"); doc.body.innerHTML = html.ToString(); extendedWebBrowser1.Document.GetElementById(formButtonName).InvokeMember("click");
I'm working on an application form for a website which implements ASP.NET validation (including client side).
I have a requirement to display a message at the bottom of the page if the client validation fails. Something along the lines of "Please go back and check your answers".
The problem is, the submit button's OnClientClick event obviously fires before the client validation.
If I enable client side validation in the view I'll get the error per the Attributes from the metadata class. If I take clientside validation out, error gets thrown from saving to the DB rather than return the view with an Error Summary.
This is the top portion of my view....
<% using (Html.BeginForm()) {%> <%: Html.ValidationSummary(true) %>
I've tried running without debugging (ctrl + f5) in debug and release mode as well as setting breakpoints and Debugging (f5) but it just seems weird to get Client side validation without server side validation. What am I missing here?
