View 8 RepliesMost of the resources on the Internet seems to discuss how to do url rewriting in asp.net. None of them seem to discuss about how to read the rewritten url.For example, I have rewritten:
http://www.test.com/users.aspx?id=12&name=sangam
to
http://www.test.com/profile/12/sangam.aspx
Now in the same page, at some point, I want to get this rewrittern url for the purpose of pointing return url in login link. Now a login link should be:
http://www.test.com/login.aspx?ReturnUrl=/profile/12/sangam.aspx
I'm trying to refresh my page when a user clicks a button; my problem is that my site uses URL rewrites.
In the past I've used Response.Redirect(Request.Url.ToString()); to achieve this, but my problem is that when I do this it does not display the rewritten URL but the URL which has my parameters specified.
For example my page is www.mydomain.com/products/cars but when i do the Response.Redirect(Request.Url.ToString()); on this I get this www.mydomain.com/products/default.aspx?type=cars My client has demanded URL rewrites throughout the site.
I have a textbox and a button on a page. When the user clicks the button, it calls a function in the codebehind that inputs the text from the textbox into a sql table. Or at least it should. I can't get it to work properly.
Here's what I have.
ascx file:
Code:
<asp:Label ID="lblTicketComments" runat="server" Visible="false"></asp:Label>
<asp:TextBox ID="txtNewCommentText" runat="server" CssClass="NewCommentText" TextMode="MultiLine"></asp:TextBox>
<asp:Button id="btnNewCommentSubmit" Text="Add Comment" runat="server" OnClick="NewCommentSubmit_Click" />
ascx.cs file:
Code:
protected void Page_Load(object sender, System.EventArgs e)
{
btnNewCommentSubmit.Click += new EventHandler(this.NewCommentSubmit_Click);
if (UserCanSeeThisTicket())
{
PrintTicketComments(); //outputs the comments to lblTicketComments
PrintlblNewTicketStuff();
[code]....
It seems the page is being reloaded before PostComment(); is ever executed, because no matter what I type in the text box, it always posts to SQL as "Write Comment Text Here..." However, if I remove the button click even and just put PostComment() in Page_Load under if(this.IsPostBack), it works fine. (but this is not ideal because I will need other buttons later which will cause a postback) So what am I doing wrong?

well what i want to find out is how can i figure out if some change occurd in page when postback , i mean when the first state of the page hahe any changes after postback . I thought maybe somehow to compare viewstaes but i can not find out how can i do that.

View 2 RepliesI'm not sure whether or not this is the correct forum...I have been asked to develop a webpage with a very simple table. 10 columns, 10 rows. Each cell will have a dropdownlist. Several people will have this page up at any given time and they will all make changes as needed. I am planning on using a SQL Server
2008 database to keep track of the entries.I need the page to verify the data it contains against the data in the database every 5 seconds or so. If they are different, either the page can refresh or (if possible) the dropdownlist can just change to the correct value.
I need to databind the gridview inside the Ajax UpdatePanel each time user types letter inside my TextBox control. How to override the TextChange event to force it do postback for me?

[URL]Initially if I make a selection it will automatically post back and firecboItemsPerPage_SelectedIndexChanged. If I then post back by clicking one of the other buttons on the page, cboItemsPerPage_SelectedIndexChanged will continue to fire, despite the fact that the value has not been changed.I want it to be postback only when selected index is changed, not in every postback
In ASP .NET 2.0, I've created a user control which is meant to work as a dropdown or popup by using an <input type="button" id="btnTogglePopup" runat="server" style="display:inline"... /> and <div id="divPopup" runat="server" style="display:none" ... /> the rest of the controls are contained inside this div, and they do mantain their values between posts, etc. This button 'runs at server' but it's not intended to post back or submit.It just toggles the popup (div) visible/hidden using Javascript client code by setting the div's style display property to "none" or "block" The problem I'm having is that when a page containing this control posts back, the state visible/hidden of the div is not maintained. If the user had the popup open, after the postback, it will display closed.I've read a bunch by now about ViewState & ControlState, and have the save and load contol state methods working, but when I step thru them they load old values (setting the popup to hidden all the time),and the popup doesn't work! I've come to think that b/c when the button is clicked,the visible state of the div is changed in client code w/o a postback, maybe I have to maintain this state info in a hidden fiel or something like that?At the same time I don't want to have a hidden field if it's unnecessary,and I may just doing something wrong.
View 2 RepliesI have a gridview control that extends the default gridview. I have added an attribute called "hiddenSelectedValues" to to the gridview during the "PreRender" event and I have a private variable that points to the value of that attribute.
I have some javascript code that modifies the value of this attribute based on the user checking or unchecking checkboxes in the grid. I have confirmed that the javascript is indeed modifying the value of the "hiddenSelectedValues" attribute by using Firebug to see the change as it happens.
However, once a postback occurs, the grid looses the updated value of this attribute and I am unable to reference get the updated value on the server side.
How do I keep the value of an attribute changed by javascript on postback?
I upgraded from 3.5 to 4.0 and noticed links in my subdomain behave differently - they still work, but add a redundant folder - for example: sub.mysite.com/sub/mypage.aspx. In 3.5 it was: sub.mysite.com/mypage.aspx. The code is thus: asp:HyperLink NavigateUrl="~/mypage.aspx"... The sub folder is a root in IIS7. Is there some way to avoid the second /sub/ showing in the broswer address bar so it looks like it used to in 3.5? Is there something I should place in my 4.0 web.config file?

I am using a custom asp.net rewriting module for some time now, and I would like to know how to reference/get a rewritten address (the url that shows in address bar) of an original url using Request.Url?
When I reference url with Request.Url.AbsoluteUri I always get the original address and not the rewritten one. One solution is to encode the original url once again, but I was looking for a different solution where I could actually reference this new url.
I'm using the UrlRewriting module on my site and I can't seem to get HttpContext.Current.Request.IsAuthenticated to return "true" on any rewritten pages.
If I go to my home page (http://localhost/default.aspx) I get "true", but if I go to something like (http://localhost/contactus) I am always getting "false".
also, for a direct example, I have an edit bar that is supposed to appear to anyone who is authenticated. The if statement fires in the Page_Load method
If HttpContext.Current.Request.IsAuthenticated Then _
Me.FindControl("EditBar").Visible = True
I have also tried putting this in the page load event
Response.Write(HttpContext.Current.Request.IsAuthenticated.ToString)
Every page that is rewritten says "False" where pages that are not rewritten say "True".
I've searched these forums, found some pretty similar problems, but haven't found solution to the following:
I'm using simple engine (IHttpModule hooks to BeginRequest) to rewrite some URL on the site and everything works perfectly as long as original URL ends with .aspx, example:
http://site/articles/Article-name.aspx rewrites to real location
http://site/DisplayArticle.aspx?name=Article%20name
Tries to use any other URL which DOES NOT end with .aspx results in that Page.Session throws an exception and Page.User is always null (Forms Authentication) Integrated Visual Studio development server works fine in any way, this is only happens when I'm trying local IIS or hoster machine.
This is driving me nuts, I cant figure out why the event OnClick doesn't fires when using a rewritten url (using URLRewritngNet).
Buttons lies everywhere on several pages and at the master page too.
I have a grid view where the user can change pages at either the top or the bottom of the grid view. I want the view to go back to the top whenever a user changes the page, whether they are changing from the top or the bottom. I've tried using anchors and javascript to achieve this but it does not work. The javascript is executed and the user is taken to the top of the gridview, this can be seen by placing an alert after the javascript to change the view. But the last thing that happens on the page change is that the window is returned to it's previous position (the bottom of the page). Is there any way of doing this?
View 4 RepliesI have this function:
[Code]....
I set itemsRead and startRowIndex in ViewState:
[Code]....
This is my PageIndexChanged event:
[Code]....
My purpose is to modified some data only for current page in a gridview. I call this function in page load and GridView_PageIndexChanged events. When it's called in page load event, it works fine. But when it's called in PageIndexChanged event, only the rows on the first page in GridView are looped through. For example, if I click page 5, the rowStartIndex becomes 100 = 5 x 20 (my pagesize). The if condition becomes itemsRead >= 100 andAlso itemsRead < 120. But after itemsRead is increased to 19, the For each gridViewRow loop stops and the if condition is never satisfied.
After some code change I have published my AJAXised web application to the server and the application failes to work properly - something weird is going on, as all .aspx pages are displayed as an ASPX markup text (page declaration, html controls, etc.), rather than a page is being rendered as an html. I have not changed the webconfig, only changed my pages' content/code behind.
