C# - Stop From Re-appending Querystrings On Form Post Back?

Feb 11, 2011

I am developing a simple rating system for my employer's profile based web-app. Here is my problem:

The actual page is domain.com/review.aspx?user=username, but I use the url-rewrite module in IIS to use domain.com/username/review The page contains a repeater control that displays reviews for that username, as well as a form for people to create new reviewsWhen the form is submitted, asp.net re-appends the (hidden) querystring to the url on postback.The post-back url is now domian.com/username/review?user=username&review, causing the page to break if refreshed.

Is there any way to keep asp.net from re-appending the querystrings that are actually already present, but re-written with IIS

Live link <- submit a review, and then refresh the page (edit) by clicking in the address bar! Beautiful yellow error message.

EDIT

C# code:

protected void submitReview(object sender, EventArgs e)
{
try
{
int starRating = txtStarRating.Text == "" ? 0 : Int32.Parse(txtStarRating.Text);
testimonials.addNew(Int32.Parse(txtHiddenUid.Text), reviewContent.Text, reviewerName.Text, true, starRating);

[Code]....

C# - Using A Timer Post Back, Which Controller To Use That Doesn't Post Back To Server?

Jul 14, 2010

Being new to ASP.NET I have run into trouble building my own Whack-a-mole program. I think my problem comes from using Buttons, which by themselves send post backs to the server, making the software unusable. The looks are in place, making new buttons show up in the grid, in different places by random. However, when a button is pushed - the score doesn't change (which I feel is strange).

Not so strange is that the Button doesn't work since it sends post back to the server - reloading the UpdatePanel. I think I should use a different controller like the CheckBox and style it hard using CSS (which isn't a problem). Is this the correct way to go, or should I make use of JavaScript AJAX instead?

Note to self: This technique shouldn't be used in a public application since it put too much unwanted pressure on the web server.

Data Controls :: Every Post Back In Form Is Taking Long Time When Several Update Panels Used

Nov 22, 2015

I have a big form in which i have almost 10 update panels. some are having updatemode = conditional and others are always. Now by default when that page is opened i only show one dropdownlist.When that project dropdownlist (from which i populate the rest of the elements in my page) value is changed by user it takes long time to load the other elements. Also the other gridview which is also surrounded by update panel and mode in conditional takes long time to show edititemtemplate controls in edit mode. 

I am unable to trace the reason behing delay. Few days ago it was working fine and fast but now it is slow.

Web Forms :: Post Back A Page Preserving Data Entered On The Form With Added Error Messages

Mar 6, 2011

asp.net with vb. I thought this would be easy but have been reading for an hour and not found out how to simply repost a page where form data has been entered and return the page with some error messages about what was entered. I want to return the page with all input controls with the data just as the user entered them before submitting. the error messages are labels that were blank when the page is first loaded. preferably the page returns focused to the topmost error error message. if that can't be done I would populate some label at the top of the page with something to the effect that 'errors were found, scroll down to see the errors'

Web Form And Ajax Data Lost On Post Back - Finding Possible Cause / Ajax Or Changing Visible Property

Sep 15, 2010

I have two Repeater controls, each hosted in a user control. Both user controls are contained in the same aspx page. Only one User Control is visible at any one time. The repeaters are comprised of checkboxes, and text boxes for user input.

The aspx page is configured with an Ajax ScriptManager; and contains several Ajax UpdatePanels. These UpdatePanels result in partial page post backs when text is changed in a textbox control in controls on the aspx page (this is not the behaviour for the Repeaters in the User Controls). Through use of several AsyncPostBackTriggers, various controls contained in the other UpdatePanels on the page have their content refreshed in response to the partial page post backs they are configured be notified about.

Depending on a radio button group selection, I set the visible property to true or false - as appropriate for the User control containing a repeater control. The Repeater control is then populated with data using databinding. All of this works.

However, when the Submit button is clicked, the Repeater control contains no data.

Given that I am not dynamically adding the Controls containing the Repeater controls (but using Visible true / false). I would have thought that the State of the fields and the data in the visible control would be preserved during the post back.

The User Controls are contained within the UpdatePanel that contains the Submit Button.

I have explicitly Enabled View state without any effect.

Am I correct in assuming that I should not have to do any explicit handling of data changes the user makes (via client side script and manipulation of an Data Structure Representing the Repeater Data); and the View State should maintain the data I need to access on the server when submitted?

I do not believe that it is the User Control visible state changes that are causing the issue because when the page is initially loaded on of the User controls is populated with dummy rows (so it displays).

I am suspicious that because the visible state of the controls is changed during partial page post back, that the Page View State ends up with no knowledge of the User Control and therefore cannot track its data (or changes).

Web Forms :: Scroll Back To Drop Down List After Auto Post Back In Code Behind?

Feb 22, 2011

Using Vb.Net 2003 Asp.Net 1.1

I have a dynamic data bound drop down list, when the user selects thier selected item I have to use the autopostback feature.

Problem is: when the page comes back it is at the top of the page not where i have the control.

I don't really need it to focus back on the dropdownlist but to scroll to it, I want to do it in the code behind.

Any "New" ways to do it, I mean new as in code from like 2010 instead of old code from the early days.

I really don't want to use Page.Register new Script...... code if I can avoid it.

What would be cool is a ScrollToControl() Function for my code behind that worked but didn't register script.

Web Forms :: Post-Back, Not A Post-back?

Feb 9, 2011

I have a very odd and disconcerning problem. Just recently a page where I have 1 textbox and a buttoon has ceased to work.

When I look at the post coming into the PageLoad, the pageType is "POST", but the Page.IsPostBack is false!! and the textbox (which had content) is empty.

I have stripped all AJAX script out, so I have a very vanilla page (in a master page) being served.

The pages is
