View 5 RepliesBeing 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.

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.

This tag should then have its "mode" attribute set to "Off"." message. when i add the customErrors mode="On" tag to the web.config i still get this error like its not looking at the web.config. ive triple checked iis and its definitely looking at the right site folder. heres my web.config:

I just upgraded a web project from VS2008 to VS2010 Ultimate (Windows7 64bit, IE8/Google Chrome. When I run the web project in the development server (by hitting F5) everything acts like it is supposed to except everything comes up blank. Even the directory structure page is blank, just an empty HTML open and close shell. I get no errors no indications of failure, nothing. When I try to use google chrome I get the same blank page no matter where I navigate to, even if I try to navigate to a non-existant location on the dev server. I know the code compiles and acts correctly because I can deploy it to our QA servers without issue.
View 2 RepliesI 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.

I have a modal popup that i use to play a video, works great.. but once you close the popup if for any reason you hit the enter key or refresh the page at a later time, it causes the popup to open again. There are 3 buttons within the page that can call this popup, so where within my code behind would i add logic to prevent it from popping up unless you click one of those 3 buttons..

I am using AntiXss library 4.0 for encoding text before displaying on the asp page.
<asp:Label Text="text" runat="server" ID="lblTest" />
<asp:ListBox runat="server" ID="lsbTest">
</asp:ListBox>
This is the asp code. In the PageLoad I am writing
lblTest.Text = Encoder.HtmlEncode("test & test");
lsbTest.Items.Add(new ListItem(Encoder.HtmlEncode("test & test"), Encoder.HtmlEncode("test & test")));
Here, when the text in the label is rendered, it shows & as &, but in the case of Listbox, & is rendered as &. But, I want this to be rendered as & even in listbox. How to do this?

View 3 RepliesCurrently whenever I need to send a request to a payment-gateway, for example, I redirect my page to another page on my website which has a form with several hidden fields. I then pre-populate the values of these fields server-side, and specify in the body tag something like 'onload="form.submit();"'
However, I'm wondering, rather than redirecting to this page, is there anyway that all this data can be collected and POSTed to the payment-gateway server-side?This will cut out the need to redirect the user to this blank page, and make everything a bit more tidy.

View 6 Replies1) The web application I'm building is a person enters information and the categories are selected by using checkboxes. The input page I have checkboxlist and it enters correctly has a one line to the database. For example, when they check one of the following Red, Blue, Orange and brown, they appear as one line in the database. When they do a search on the individual I need the checkboxes to return that they were selected when it returns information from the database so they update the information or deselect a color or something. Do I need a autopostback on the checkboxlist?
2) Is it possible to have a search page base on checkboxes. For example, the user checks red, and blue. Clicks on the search button. On a gridview every person who checked red and blue when they first entered information will appear in the gridview. Do I need a checkbox result table with a bit field?
I'm not sure which way I should go with this. Just asking for a direction in how I can do this.
i am thinking to capture which button has caused a postback in the web pages.
Is it possible to do so?
I have orders page. When user submit Order, I need to disable the button to avoid multiple transactions. I also have few validation controls on the page, so button should not be disabled untill page is about to be posted. I dont have any custom javascript for validation. It is just these asp.net validation controls. What is the best way to achieve that? I have spend about 2 hours on google and found various solutions, but nothing seems to work. Each has some issue. On button I add OnClientClick="return btnOnClick this, 'Payment');" Below is what gets called. Unfortunately if I disable button, it cancels post back. So I am calling dopostback and also adding few lines on server side to see which button caused postback. It works fine in IE8 and Chrome. But for Firefox on server side arg comes null. Any ideas what is wrong with my code? Or any other suggestions to do it in a better way?
C# Server side
string arg = this.Request.Params.Get("__EVENTTARGET");
if (arg == "Payment") { this.ProcessPayment(); }
Button
<asp:Button ID="btnSubmitPO" OnClientClick="return btnOnClick(this, 'Payment');" runat="server" Text="Submit Order" ValidationGroup="G" />
alert(group);
