Please take a look at the following click event...
Protected Sub btnDownloadEmpl_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnDownloadEmpl.Click
Dim emplTable As DataTable = SiteAccess.DownloadEmployee_H()
Dim d As String = Format(Date.Now, "d")
Dim ad() As String = d.Split("/")
Dim fd As String = ad(0) & ad(1)
Dim fn As String = "E_" & fd & ".csv"
Response.ContentType = "text/csv"
Response.AddHeader("Content-Disposition", "attachment; filename=" & fn)
CreateCSVFile(emplTable, Response.Output)
Response.Flush()
Response.End()
lblEmpl.Visible = True
End Sub
This code simply exports data from a datatable to a csv file. The problem here is lblEmpl.Visible=true never gets hit because this code doesnt cause a postback to the server. Even if I put the line of code lblEmpl.Visible=true at the top of the click event the line executes fine, but the page is never updated. How can I fix this?
I have been trying to figure out out to force a postback from an asp ajax extender. The closest post that I can find is
http://forums.asp.net/t/984558.aspx
However I am pretty sure this was at least one migration ago. Additionally I am using VB as my programming language so some of the conversion may be the problem.
I think I am pretty clear on what needs to be done.
If I am correct the steps are...
Create a new property in the extender to hold the postback command for each target control that is using the extender.
Then in the Onload populate that property (Use GetPostBackEventReference to get the ASP valid target ID ) so it can be called from the Clientbehavior.js
My problem is the syntax in the for-each loop that allows me to iterate through the target controls.
Protected Overloads Overrides Sub OnLoad(ByVal e As System.EventArgs)
I am aware that a FileUpload requires a full page postback. I read the article http://www.4guysfromrolla.com/articles/090209-1.aspx[^]I tried to install a PostBackTrigger programmatically to get a full postback only on the ImageButton1 control. All other postbacks must be partial. (GridView sorting, paging, ...)In code behind I do :
[Code]....
The above code does not seem to install a full postback only for the ImageButton1, so the file upload fails. How can I make this work ?
I'm trying to solve a problem and am open to any suggestions. Here's the situation:
I have a checkout page that has an iFrame that contains a credit card form. The credit card form resides on an external site that is PCI compliant (and it is a requirement that we are PCI compliant so having the credit card form on our domain is not an option). When the user submits the checkout form, I need a way to force the submission of the iFrame form on the server side. This is because I need to wait for the credit card form's site to send back a reply via a web service on my end, which will be passing a token that I save and use later on when the order is submitted. I also will display any validation errors that are reported from the credit card form site, also via the web service.
This all worked just fine in a simulation, but I'm getting permission errors trying to access the form in the iFrame across domains (and after researching this, apparently it's not possible to access an iFrame's document across domains). I need a way to force the submit of the iFrame form on the server side without having access to the form itself. Can this be done? Can anyone suggest an alternative to what I'm trying to accomplish?
Hoping I have placed my question in the correct forum.
I am writing an application that simply updates a text box (contained in a AJAX UpdatePanel) via a thread. the eventual idea being that the textbox will be placed in the master page, and a thread will poll a table to check for status messages. 90% of the code works as it should, the only side that is not working, is physically updating the textbox. The value of the textbox is being updated, but it is not being reflected on the screen. When the text is updated in the textbox, the OnChange event is not firing (as it shouldn't), but I still need the textbox to be updated. The textbox is being updated prgramatically, and not by the user.
When the thread triggers, it just fires an event, which right now just updates the textbox with the current date time. I've tried a million and one different ways, but still no luck :( Anyone know where I am going wrong?
I am having a problem editing VB.NET .aspx pages in Visual Studio 2008. If I edit a line that is flush against the left margin, Studio automatically indents it 4 spaces, and there is no way to undo it! I am forced to save the file with that 1 line I edited indented differently than all the other lines!
I have a textbox that the user is supposed to enter "City, State". I also have a geoIP lookup that enters that information in for them. If that fails, they would enter it in, and autocomplete will suggest the city and state.The problem:
I'm trying to keep track of employees in my database. I have two tables, Employees and Departments. The Employees table contains a foreign key relationship with Departments through a column named DepartmentID.
Here's my entity:
[code]....
I have a page that contains a form to add an employee. I'm passing the entity to my view page, and calling <%: Html.EditorForModel() %>
The problem is that the view creates a textbox for the DepartmentID.
How can I force the view to display a dropdown for DepartmentID that contains all the Departments in my database as the dropdown's list items? Is there a way to do this by just adding a metadata attribute to the property in my entity?
I have a problem at the moment that I cannot figure out how to solve. I have an asp:Wizard control on my page, which contains a google map. Now, for google maps, you need to specify what html will be put into the info windows (the little bubble that comes up when a marker is clicked).
What I want is for my info window to have a 'Select and Continue' button in it, which would act the same way as if the user clicked the next button on the Wizard at that time.
So when I create the html for the info window, I have the following:-
[Code]....
However, the page just seems to reload, and the wizard doesn't move on to the next step.
I might be wrong about what is actually happening here but i have 3 Html.dropdownlists. And im using jquery to handle filtering which does actually work. However, there is some odd behaviour which i think might be because data isnt finished loading before the next function is called. For instance: Some background. Company: Owns several field offices Field Office: Owns several facilties So logically, when you change company, field offices should change, which then changes facilities.
$(function () { $(document).ready(function () { var cid = $("#CompanyId").val(); $.post("/ManifestSearch/GetFilteredFieldOffices", { id: cid }, function (data) { $("#FieldOfficeId").loadSelect(data); }); var fid = $("#FieldOfficeId").val(); $.post("/ManifestSearch/GetFilteredFacilities", { id: fid }, function (data) { $("#FacilityId").loadSelect(data); }); }); }); Now, when the page loads, everything looks fine. All the dropdownlists have the correct data. When i change company, this calls. $(function () { $('#CompanyId').change(function () { var cid = $(this).val(); $.post("/ManifestSearch/GetFilteredFieldOffices", { id: cid }, function (data) { $("#FieldOfficeId").loadSelect(data); }); var fid = $("#FieldOfficeId").val(); $.post("/ManifestSearch/GetFilteredFacilities", { id: fid }, function (data) { $("#FacilityId").loadSelect(data); }); }); });
This changes the field offices to the correct list, however facilities changes to whatever field offices was set to before the company change occured. I dont know enough about jquery to figure out exactly what is going on, but my instinct tells me that the two posts are happening at the same time, and the second post happens before the first one is finished.
I'm working on a questionnaire type application in which questions are stored in a database. Therefore, I create my controls dynamically on every Page.OnLoad.This works like a charm and ViewState is persisted between postbacks because I ensure that my dynamic controls always have the same generated Control.ID.
In addition to the user control that dynamically populates the questions, my questionnaire page also contains a 'Status' section (also encapsulated by a user control) which represents the status of the questionnaire (choices are 'Complete', 'Started' or 'In Progress'). If the user changes the status of questionnaire (i.e. from 'In Progress' to 'Complete'), I need to postback to the server because the contents of the dynamic portion of the questionnaire depend on the selected status.
Some questions are always present regardless of status, and yet others may not be present at all for the selected status. The point is, when the status changes, I have to postback to the page and render the right set of questions. Additionally, I need to preserve any user entered values for those questions which are 'always available'.
However, due to the page life cycle in ASP.NET, the 'Status' user control's OnLoad, which contains the correct status needed to load the right questions from the DB, doesn't get executed until after the 'dynamic questions' user control has already been populated (with the wrong/stale values).
To get around this, I raise an event from my 'Status' user control to the main page to indicate that the Status has changed. The main page then raises an event on the 'dynamic questions' user control. Since by the time this event bubbles up, the 'dynamic questions' user control has already loaded the 'wrong' questions from the DB, it first calls Controls.Clear. It then happily uses the new status to query the database for the 'correct' questions and does a Control.Add() on each. FYI, Control.IDs are consistent across postbacks.
This solution works...sorta. The correct set of questions for the selected status do get rendered; however ViewState is getting lost for those 'always available' questions. I'm guessing this is because the 'dynamic questions' user control calls Controls.Clear when responding to the status changed event. This must somehow kill the association between ViewState and my dynamic controls, even though the Control.IDs are consistent.
This seems like such a common requirement, I'm virtually certain there is a better, cleaner and less error prone approach to accomplish this. In case its not plainly obvious, I haven't been able to grok the ASP.NET page life-cycle despite working with it for the last year.
I have a MaskedEditExtender set for a TextBox that will receive a fee amount. I want the user to be able to type the "." decimal when the amount contains a decimal value (123.45). But if the amount has not decimals (123) I want the mask to automatically fill the 2 decimal with zeroes and also enter the "." decimal point (123.00).With the following mask I'm able to enter a full number (999) and get the zeroes but when user enters 85.85 it will be 850.85 so I change the direction RightToLeft but I'm not even able to type the first character.
I have some issues regarding listing images from inside a directory. What I want to do is to create a Default.aspx page that will search and list the images located inside a folder of my website (where I simply drop them in it). I tried with a treeview, DirectoryInfo and both worked when I compiled my website with visual studio, but when I access them via another computer, I get a 404 for the page. My bet is that iis7 is blocking my code from accessing the folder containing the images. Any idea of how to fix this and make it work ?the code I use to browse in my image folder
string path = AppDomain.CurrentDomain.BaseDirectory; DirectoryInfo diFiles = new DirectoryInfo(AppDomain.CurrentDomain.BaseDirectory + @"contentmiscimages"); foreach (var f in diFiles.GetFiles("*.jpg")) { Lit.Text += "<a href="" + f + ""rel="lightbox[img]" title=" + f + ">" + f + "</a>" + "<br />"; //I format the image as an url inside a literal }
writing code for Session_Start() and Session_End() such that whenever a user closes the browser without logging out he is automatically forcely logged out......And too when a user logs out normally he is re-directed to the LogOn page....
http://mysite.com -> https://www.mysite.com OK http://www.mysite.com -> https://www.mysite.com NOT WORKING
I guess the condition is not being satisfied when I enter www.mysite.com in the browser, so there's no redirect and the page serves as HTTP instead of HTTPS.
I think I just need to modify the condition pattern, but I have almost nothing regex knowledge and I need this asap.
How can I set up my page load event in my code behind to redirect to an url that has an https prefix? I would need it to work with urls that have query strings attached too.It's one thing to construct a link that goes straight to the https page, but I don't want the user to be able to manually change it to an http page.Also I don't want to do it with javascript because it might be turned off.
I have 2 textboxes and a submit button inside a .net composite server control. I tried to only postback when submit button is clicked. I set autopostback = false for both textboxes. But either one still trigger submit button's onclick event by hitting "Enter" inside textbox. How can I stop postback by enter key?
When an asynchronous postback happened inside update panel, another postback happens also for MasterPagenot only update panel embedded page .I want to prevent this MasterPage postback . is this possible ?think like i have a MasterPage and another page which is test.aspx which is content page of MasterPagei have update panel at test.aspxwhen asynchronous postback happens at this test.aspx update panel it also loads MasterPage Page_Loadi want to prevent this (it should not also load MasterPage Page_Load)
