Web Forms :: Why Page Load Event Is Marked As Protected

May 10, 2013

Usually when we create an aspx page and then open the aspx.cs page we can see a protected void page_load().So my question is why that should be protected in default.Can we give other access modifiers.

How To Create A Base Page Event That Fires After The Derived Page's Load Event

Jun 30, 2010

How 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

How To Load IFrame With Hidden Fields After The Page Load Event

Jun 21, 2011

I am using a third party gateway. The third party gateway does not support query-string , so i will need to post the form to pass the values to the given URL and another thing is that they don't expose the web-services so we need to use their page and that means we need to host it in an iframe in asp.net

so what i did is that i have hidden fields that will be used as parameters as depicted below

Code:
<input type="hidden" name="p1" value='4635' />
<input type="hidden" name="p2" value='Reference_test' />
<input type="hidden" name="p3" value='Purchase credits' />

[Code]..

Now the purpose of this , is to load the iframe after the page load event of the asp.net gets fired.

Now my problem here is that when the iframe loads , it does not pass the parameters to the url that is being set in the iframe.

I have attached the example, project. (2kb)

When you run the project you will notice when the iframe loads there is an Error

"NO VCS ID"

now this means that the parameters were not passed when the Iframe loads , i can understand because it seems like iframe does not do a full form post. so to demonstrate what i want, click the proceed button and you will notice it will give you a page with no errors and it will be a page where credit card details are required , i want to iframe to load that the first time.

Web Forms :: Button Click Event Is Called Before Page Load?

Oct 8, 2010

I just discover why some validation is working bad on some of my forms: the button click event is being called before page load.

What I need for good is (I consider this is a normal cycle of events):

The user press a buttonSome validation occurs at client side (js function returns true if success)Some validation occurs at server sideThe page loads again showing the results
But this is what I get (BAD):

The user press a buttonSome validation occurs at client side (js function returns true if success)The page loads showing no results, because server validation hasnt happened yet Some validation occurs at server sideThe page doesn´t loads again and I cant see the results, so my client cant know what happened on the server side

This is how I tried to implement this:

Web Forms :: Displaying 2 Alternating Db Records With Each New Page Load Event?

Oct 14, 2010

I have a webpage which displays content drawn from a single record in a database table. I've been asked to change this so that the content displayed alternates between 2 records each time the page is requested by a browser (I guess this would equate to each PageLoad event).

The records to be displayed are chosen on the basis of two dates, a beginning date and and ending date, that define a time period in which the record is to be active. The table containing these records has 2 columns containing these dates (begin date is contained in "dtDisplay" and end date is "lastDisplay."

I'm not sure how to amend the existing code behind to make this happen. Here is the c# that I inherited from a developer who is no longer available.

Web Forms :: Master Page Load Event Firing Multiple Times

Jan 27, 2010

am using a master page, with children pages.

I am using forms authentication, and a session object to hold user information once the user is authenticated.

I am able to login and log out. I am able to log in and use the "remember me" functionality of the forms authentication.

When attempting to test the "remember me" functionality, the master page load event contains code to check the forms authentication & remember me, and retrieve user info from the database to automatically log the user in. This fires correctly, and the screens all load with the user successfuly logged in, and the users info is successfully stored in a session object.

Without touching anything on the screen, a moment passes and then the master page load event spontaneously fires again, Page.User.Identity.Name still contains the user name, however the session variable is now null, and throws an error.If I tell it to run past this error, it does, and the application continues to function normally, withthe session variables set correctly.

Its almost as if that second firing is ina different session, or something.

I have no problem posting code, but I have a profile class holding / handling the session communication, etc so it is a bit cumbersome.

Web Forms :: User Control Accessing The Parent Page Load Event?

Mar 4, 2010

I have an EDIT.ASPX page and on that page I have some labels and textboxes and a user control. I listed all the related codes you can have a clear picture - not all of the codes are given me a problem. ONLY ONE.

HELP ---> On the Uer control (SiteTemplate2.ascx) I have a DataList that is being populated by the database and that works fine. I have a
CHECKBOX on the user control page each time the user check the CHECKBOX the user control content totally disappears from the EDIT.ASPX page. There is no error message -- I believe this is a post back error but I don't know how to fix it.

Goal: Each time the checkbox called (CHKBSideBar) is clicked on the user control page all of the page content should stay in place that include

EDIT.ASPX Page and the refeneced USER CONTROL. I should be implement a CheckedChanged Function without either of the pages lossing DATA. I need to be able to access post back event from the user control of the Edit.aspx page. When the user click a box on the user control page how do I keep the same Page_Load event on the edit page. I need to reference the Edit page from the user control.

Note: The edit page loads the user control (SiteTemplate2.ascx)SEE CODES BELOW

I know this is a lot and thank you in advanced for your help. I tried to include all the pages that are key players. I must user the user control bacuase the user can select different template so eliminating the user control is not an option.

'*******************************************************************

The user control is being referenced from the web.config file ** Works find! **

Dropdown Selected Index Page Event Fires On Page Load

Mar 26, 2010

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) ...................
