I have a page showing the number of hits(or views) of any selected item. The hit counter procedure that is called at every page load i.e
if (Request.QueryString.HasKeys())
{
// get item id from icoming url e.g details.aspx?itemid=26
string itemid = Request.Params["itemid"];

In my web form, i have 2 drop downlist controls. eg. dropdown1 and dropdown2. I will change the dropdownlist1 item, consequently selectedindexchanged event fires and reloads the dropdownlist2 items. And i have another button also in order to get the result based on the dropdown1 and dropdown2. Lets say for example, i have a list of countries in dropdown1 and a list of states in dropdown2. I selected "India" in dropdown1 and correspondingly "Tamilnadu" in dropdown2. And then click a button which calls the dataset based on dropdown1 and dropdown2. The problem i face here is, whenever i click on the button to load the dataset, dropdown1 value remains the same as the dataset is not called again, whereas the dropdown2 value changes to the first one as it gets called automatically during postback. For your information, I have loaded both the lists in the page load using (!IsPostback) property.
My coding is as follows:
protected void Page_Load(object sender, EventArgs e)
{
try
{
if (Session["sesUserName"] == null)
{
Response.Redirect("sessionExpr.aspx", false);
}
else
{
lblStatus.Visible = false;
pnlEvaluate.Visible = false;
if (!IsPostBack)
{
fnLoadDropDown1();
fnLoadDropdown2();
}
}
}
catch (Exception ex)
{
throw ex;
}
}
public void fnLoadDropDown1()
{
dsLoadDD1 = objWebRef.fnLoadOnlineTest();
if (dsLoadDD1.Tables[0].Rows.Count > 0)
{
ddTestTitle.DataTextField = "vchTestTitle";
ddTestTitle.DataValueField = "intTestID";
ddTestTitle.DataSource = dsLoadDD1.Tables[0];
ddTestTitle.DataBind();
}
}
public void fnLoadDropDown2()
{
dsLoadDD2 = objWebRef.fnLoadOnlineTest();
if (dsLoadDD2.Tables[0].Rows.Count > 0)
{
ddUser.DataTextField = "vchUser";
ddUser.DataValueField = "intUserID";
ddUser.DataSource = dsLoadDD2.Tables[0];
ddUser.DataBind();
}
}
protected void ddTestTitle_SelectedIndexChanged(object sender, EventArgs e) ...................
I can't figure out why, but before my form is even displayed, the CheckChanged event fires. I don't even have a chance to check anything. Has anyone seen anything like this?
View 3 RepliesI have a script manager and 3 update panels on my page. I am not very familiar with AJAX but I would think anything in the contentTemplate would not cause a postback and page reload, but they all do, here is the outline of the SM and UpPanels

View 1 RepliesHow do I create a new event in a base page class that fires after all derived pages have fired their load events but before any controls fire their load events.
The following code fires the event before the derived page's load event. I want it to fire the event after the derived page's load event but before all control load events:
Base Class:
Public Event FirstLoad(ByVal sender As Object, ByVal e As System.EventArgs)
Private Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not IsPostBack Then
RaiseEvent FirstLoad(sender, e)
End If
End Sub
Derived Class:
Private Sub Page_FirstLoad(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.FirstLoad
'Stuff here happens before controls load but only on first page loads'
End Sub
I am embedding a popup extender inside a tab...simple enough - for some reason the content is visible when the page loads - it can be dismissed by selecting the button and then dismissing the popup. Everything works in compatability mode.
I can't tag the panel as visible=false as it is no longer rendered at all.
[Code]....
When I run the web application, I notice that Page_PreRender is fired twice. This only happens the first time in a new session. It does not happen if I refresh the page, or on postbacks. I use .NET framework 3.5 and the built in ajax functionality.
The problem is not related to img tag with empty src attribute (which I have seen other posts with similar problem has mentioned). I know this because I see this in both FireFox and IE. The posts I saw about this stated that this was not a problem in IE. I have also searched and found no img tags with empty src in the generated page source, so it should not be this. I have also made a simple test page where I have included some of the functionality, and this does not happen.
Note: It is the entire page cycle that is firing twice, not just render.
I downloaded Firefox 4 yesterday and when I try to open my site (ASP .Net 2.0 site using masterpages) it tries to open the file rather than display the page. The message in the popup is: "You have chosen to open contactus.aspx which is a: aspx File from: 'my site'. What should Firefox do with this file?"
I am sending the following content-type: <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> I also tried changing the charset to utf-8, same thing.
When I try to run the page through the w3 validator it gives me this message:
Warning Character Encoding mismatch!
The character encoding specified in the HTTP header (utf-8) is different from the value in the <meta> element (iso-8859-1). I will use the value from the HTTP header (utf-8) for this validation.
Is the server (IIS) somehow setting the default charset? Could this mismatch be the problem? What else can I look for? Also, one more thing, I have a mobile site running on the same server which uses "application/xhtml+xml; charset=utf-8" as the content-type and it works fine in FF4.
Edit: here is an example page from the site: [URL]
Edit 2: I think I have narrowed down the problem to the mobile detection. I am using 51 degrees mobile device detection from [URL]

I initially tried just making them a page method but that didn't work at all (My guess is ServicePath can't read .Master instead of .aspx properly)

I have an ASP.NET page using the AJAX library. There is a dropdownlist inside an UpdatePanel, which on index changing is supposed to update a different UpdatePanel to modify a grid control.But after the page first comes up, and you adjust the ddl, the entire page postbacks, followed by a (correct) partial postback. After this one time, every other usage of the ddl performs correctly, trigger partial postbacks.
Both the panel and the ddl are being added from code. The UP is Conditional updates and ChildrenAsTriggers = true. The dropdownlist is AutoPostBack true and has an event set up on SelectedIndexChanged.So what is going on? I've tried adjusting every setting I can think of and still the page completely refreshes once, then works fine after that.
I have a page which contains linkbuttons and panels. all panels have DetalilView and gridView controls. On click of linkbutton, panel's visibility is set. everything works fine on my local server. But on production server, no events of Button, DetailsView and GridView fires.
View 5 RepliesI have an update panel which contains a number of controls. The update panel is triggered by the OnSelectedIndexChanged event of a dropdownlist called: ddlUSCitizenshipStatus. It works as expected when I selected a new item.
However, if I leave ddlUSCitizenshipStatus with the default value, and then click "submit" button on the page, the requiredfieldvalidators say there is an error on ddlUSCitizenshipStatus (which it should, as I never selected a value). So I then choose a value, the error message goes away on ddlUSCitizenshipStatus, however the updatepanel does not refresh. I've debugged this locally and the OnSelectedIndexChanged event for ddlUSCitizenshipStatus does not fire.
If I choose an item in the ddlUSCitizenshipStatus list a second time, the OnSelectedIndexChanged server event fires and the update panel refreshes and works as expected.The issue is, I have to select an item in ddlUSCitizenshipStatus twice, after failed validation, before the updatepanel it's sitting in updates.The submit button on the page looks like this:
[Code]....
If I remove my custom OnClientClick script, making the submit button look like this:
[Code]....
The dropdownlist, update panel, and reguiredfieldvalidator all work as expected. However, I need to run that custom "ValidatePage()" script when the button is clicked.Below is what my ValidatePage script looks like. I've been troubleshooting this for more hours than I can count.... I hope someone is able to help me. Please let me know if you can figure out why ddlUSCitizenshipStatus doesn't update the updatepanel until the second click after a failed validation.

View 3 RepliesI have a modal popup and the CSS prevents anything from being entered on the main page.
However, when I hit enter while the modal popup is displayed, a button on the main page is fired.
It seems to only happen if the button on the main part of the page is pushed down out of view so it is not currently on the screen.
How can I prevent a button on the main page from firing when the user hits enter?

we are creating a custom content management and out portal page is bit bulky it is about 60Kb without images.
and during loading the page in some browser we can see some parts of site load faster than the other parts of the site where as we want to indicate (or instruct the web server) to load some of the areas first then load rest of the page.
is there any particular setting in IIS for is there any particular method in classic asp for doing that?

I'm developing my first Facebook application in ASP.NET 2.0 and doing a simplest thing, that is, to show a navigation on top with four hyperlinks where each link targets to another .aspx page. How can I do this using FBML in ASP.NET 2.0?
Otherwise coming to my question, where I'm struck after trying above thing at myself and failed then had to go around the Ajax way of doing this. Now I'm using Ajax call over the onclick event of each hyperlink from top navigation and it's succesfully loading external .aspx pages (for example,[URL]. The problem is when user comes on the application on first time, it only shows the .aspx page which has a navigation and a Ajax content place holder which is programmed to be filled with contents on click event.
How to load Ajax contents into the Ajax content place holder on page load without a click event?
