Javascript - Multiple Page_load When Using Script To Set Src Of Iframe?
Sep 7, 2011
I have a jQuery modal that pops up when a customer clicks on a link on one of my product pages (which is a classic asp store...) This modal contains an Iframe, Within this Iframe sits my .net vb form.
The src= for the Iframe is populated with script when the link is clicked.when the form is loaded within the Iframe I have a SQL insert on page_load..For some reason Im getting 3 inserts into the database instead of the one? when I debug my app locally it works perfectly. Can anyone help? Perhaps somone knows a better way of achieving what im trying to do? I want a sexy modal that pops up with my .net form in it from my classic asp page..
In an .aspx page with a VB.NET codebehind I am using an IFRAME which would be created inside the repeater control. Since I want to resize the IFRAME based on the content within the page I have been using the resize function obtained from here on the IFRAME onload as shown below.
I'm trying to convert an old ASP.Net 1.0 application to ASP.Net 3.5 and am running into trouble with a JavaScript function. The application passes in content into an within a table cell. The function is supposed to calculate the height of the content and size the table cell appropriately.
way of accomplishing this with the
JavaScript function
<script language="javascript" type="text/javascript"> <!-- function calcHeight() {
I have two ASMX web services consumed from javascript. The first service performs a long operation and updates a database table on its progress. The second service polls that same database table in order to report the progress to the end user via a progress bar.
My problem is that the long process seems to be blocking the polling service. When I log the activity of the javascript, it seems to be requesting the long service correctly, and then starts to request the polling service once a second asynchronously (note: the long process is asynch as well). Both request types either use setInterval or setTimeout which shouldn't halt the browser. Yet when I look at the activity of the javascript, none of the responses from the polling requests return until the long process completes. So it seems the long process is blocking the polling requests until it's done.
I've got an sql datareader that has a bunch of paths in it. I need to open up multiple pop up windows / multiple tabs on the browser.So I tried looping through my datareader and doing a ClientScript.RegisterStartupScript but after the code completes nothing opens up.
I have dynamic html table and every cell have one checkbox. I want to get the selected checkbox if the user select from multiple checkbox from different row.
function GetAllChecked() { var chkedshid = new Array(); var rows = new Array();
[Code]....
why why this function return just last selected checkbox for last row in loop? i need the all selected checkbox for all rows!
So here is the situation. I have a button on one of my extjs pages. This button opens a child window as a pop-up. This child window has a .method attribute as well as a .ref attribute, and also a .id. I need the functionality to open another window with the SAME template, everytime I click that button.I was thinking set the childwindow .method property to something like 'getWindow', and the .ref to something like 'newWindow' and then create a javascript function on the backend to look something like this:
var myArray = []; var count = 0; function getWindow() {
On the page being called, I'm using the following vb.net code to retrieve the querystring variables and write them to a database:Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
[Code]...
Each of the javascript blocks above worked locally as intended but failed in the same manner with multiple DB writes and Firebug "Aborted" status.If I call the url+querystring directly via the browser, everything works as expected. (Edit) Also tried using the full path url in the code above - no improvement.
I know how to call a simple old fashion asmx webservice webthod that returns a single value as a function return result. But what if I want to return multiple output params? My current approach is to separate the params by a dividing character and parse them on teh client. Is there a better way.
how to override the page_load or any other base page event every time in an application? I keep finding half examples and answers around the web. I want to fire this method every time a page is loaded.
I am upgrading a 1.1 web app to 4.0 and am running into an issue with the page_load of a custom user control firing twice, both being treated as non-postbacks (IsPostBack is false in the case). I have read around and it seems that there are 2 culprits to this, 1 being an img tag without something in the src part (which there are no images on this page at all) or 2 an issue with AutoEventWireup and Handles being used at the same time. I have looked through all my code and there are no Handles keywords in there at all and AutoEventWireUp is set to true on every page, yet I still get this issue.
have a look at my VB/ASP code and tell me if you can see what's wrong (I highlighted the important segments in red):

Basically, I'm trying to get the Page_Load subroutine to execute on the page load, but it doesn't seem to be called. I'm assuming that because I set my feedback label to "feedback" in the Page_Load subroutine, I should see it displayed on the page saying "feedback" on first loading the page and every time I refresh. But this doesn't happen. I'm lead to conclude that the Page_Load subroutine is not being called on the page load.
i have 1 master page with 5 pages that call it. now on the master page, I have few dropdowns and textboxes, and the calling pages only have a small article in the corner. I want to start a session on page_load event, so that if the user chooses to select a dropdown or put data in textbox, even if he clicks on the other 4 links of other pages, the data should stay.how can this be done?
I am trying to set the class attribute of a list item on page load. Dim liItem As HtmlGenericControl = DirectCast(Page.FindControl("default"),HtmlGenericControl)liItem.Attributes.Add("class", "active")
This code doesn't work, not quite sure why.This is the error it is generating "NullReferenceException: Object reference not set to an instance of an object"
sub Page_Load //Get data form databse and show it end sub sud deletsome(Source As Object, e As EventArgs) //delete one record when user click on submit button end sub
When I click the button, the page reload, all the data have no change, I must re-enter the page again, the record I have delete disappear. Can you show me why? The full code here:
i have a question ( i am learning VB) is there is a way in vb.net to make the Me.LoadComplete loads after the client side , i develop this simple code to make it easy to understand my question
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.LoadComplete MsgBox(myhiddenField.Value) End Sub
[Code]...
when the page loads , the MsgBox will be empty but when you click the link button the MsgBox has the value you set in the javascript , so i assume that the page_load function gets excuted first the question is how can i load the client content before the page_load ?
I'm just starting out looking at asp.net. I've got this code that works in VB, but not in asp.
I've put this in the page_load:
Dim db_con As SqlConnection, ssql As String, db_cmd As SqlCommand, rdr As SqlDataReader db_con = New SqlConnection("Data Source=myServer;Initial Catalog=processes;User Id=usrID;Password=mypwd;")
[Code]....
why this wouldn't work in asp.net? The issue is that the label is blank. In vb.net as soon as the form is shown, the lable says "It connected".
I have a problem with running code in the right order. What I am trying to do is updating a session state variable when I press a button. When I run my code it always runs the event handler for the button after my page_load function.The reason why I need to run it after page_load is that, thatI add a line to the textList. Which the loadGui() should add to a table. The table has a remove button for all lines so the loadGui() function can not be added later becuase then the event handler of the remove buttons wont work.
User press the add button which add a row in the TempResponse Session(TempResponse) gets updated loadGui() runs and includes the newly added row Sub Page_Load()
I have an default.aspx page that I'm trying to have redirect the user to a different page depending on whether or not their deviceId is stored in the SQL Server database. It should direct the user to the login.aspx if the record for the user is found or to the newdevice.aspx page if there was no record found. I want this to occur on Page_Load but have not been able to figure it out so far.
I am populating the DropDownList ddlItems in the Page_Load event. I am then changing the current selection of the DropDownList in the Page_Load event but the dropdownlistbox.SelectedItems aren't firing up. Can anyone please help me? The dropdownlist keeps on repopulating and I cannot stick with one value that I have selected.Here's a screenshot of the problem.I want to have the value LK00260 selected when I PostBack.Instead of having to see "Add New Item" everytime I postback OVER AN OVER AGAIN.
[code]...
I don't want 'Add New Item' to show up everytime I repopulate the box. Instead, I want a value that I have selected such as 'LK00260'. Can anybody please help? I have AutoPostBack set to true already.

If Request.QueryString("ID") = "" Then folderDirectory = Global.FileUpload.GetFolderDirectory(Request.QueryString("TFID")) If Not File.Exists(folderDirectory + fileName) Then If Not Directory.Exists(folderDirectory) Then Directory.CreateDirectory(folderDirectory)
Im making a site in Visual Studio using vb and I have a variable in page_load but need its value in the event handler of a button for passing on session.
I'm fiddling with sessions in asp.net in a http module.The problem:
session("whatever") = "something"
is set on page_load I need an event in the http-module which is executed after page_load, and in which I have access to the session in System.Web.HttpContext.Current.Session I was looking at this HTTPModule Event Execution Order? but I can only get the session in PostAcquireRequestState, which obviously comes before page_load...
I have two radio button on my asp.net page, with AutoPostBack = True When I click on either of those, they each set a flag SaveData=False However, when I click on them, the page_load event occurs first, so the page_load event saves the data, then the radiobutton_OnCheckedChanged event is triggered. How can I trigger the OnCheckedChanged before the page_load event?
