.net - HTML Input Not Working Correctly With AJAX Update Panels Used Else Where On Page?
May 20, 2010
I have some update panels on my page that do some asyncpostbacks to keep some dropdownlists correctly populated. My problem is that on my page i have an HTML input that is handling some file uploads. With the AJAX on the page with asyncpostbacks, and while i step through my code behind, the files arent being uploaded. Using a postbacktrigger (non-async) is not possible because of my layout.
When I put a breakpoint in at the declaration of service and then check the value of "files", the count is 0. I am expecting it to be 2 when i have one file uploaded.
Is it possibel to use update panels and update progress controls in windows application or is that reserved for web apps only. I am looking at applying some progress controls (like a spinning wheeel etc) when loading a crystal report that take about 30+ seconds.
This is a follow up to another question of mine. The solution I found worked great for every one of the test cases I threw at it, until a case showed up that eluded me the first time around.My goal is to reformat improperly formatted tag attributes using regex (I know, probably not a fool-proof method as I'm finding out, but bear with me).
My functions: Public Function ConvertMarkupAttributeQuoteType(ByVal html As String) As String Dim findTags As String = "</?w+((s+w+(s*=s*(?:"".*?""|'.*?'|[^'"">s]+))?)+s*|s*)/?>"
im trying to find a way of resizing a html document to fit inside my browser correctly.
I would like the width of the page to be the same width of the browser. I can scroll down for the rest. I have no idea on how to do this. Ive found some bits and pieces on the net but nothing is working for me.
Private Sub WebBrowser1_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
I use the following statement to position which row to update; Dim salonToUpdate = (From r In db.Salons _ Where r.StoreID = storeID _ Select r).Single() If fileDate = #1/1/1900# OrElse fileDate = Nothing Then SalonToUpdate.LastDownLoadDate = TableDate [Code] .....
I've double checked to make sure none of the dates are invalid or null, but when the bolded statement executes, the following sql runs through the trace: exec sp_executesql N'UPDATE [dbo].[Salons] SET [LastDownLoadDate] = @p0 WHERE 0 = 1',N'@p0 datetime',@p0='2008-01-04 00:00:00:000' Of course it's going to fail if LINQ is passing in where 0=1 every time. Shouldn't it be using some unique row identifier, (in my case, the salon id), to update the specific row?
I wrote a page Page method in my aspx page. in web service method I need to call FindControl method return textbox and get text box value. But my findControl will take MasterPage object to iterate.
see my code
<script type = "text/javascript"> function ShowCurrentDateTime() { $.ajax({
[Code]....
How to pass Master Page object or Page to Page method?. So I can use in Sared method.
Is there any way I can access Textbox value directly in Page method? I need access couple of controls in Page Method.
I use new WEBBrowser control (VS2005) in my program (WinForm) for open web site. (VB2005)After using method "navigate", in my webbrowser control I have HTML page from some website.This HTML page has some input button with events or input text control or other interactive control on it. I can click with mouse on that buttons or input text from keyboard or select value from combo box to send this page back. question:How I can execute this from my program code, using property and methods WebBrowser control?
The code below works "correctly" as far as sending the email address to the SaveEmail URL and it gets saved correctly each time I change the drop down. However it only outputs the "Successful" message once, no matter how many times I change the value in the drop down. The "data" that is returned is "Successful". I would like to show the message for a couple seconds, then fade it out. It works correctly the first time I change the drop down, after that the change happens and the value gets saved, but the "Successful" message doesn't display.
HTML code: <select ID='AgentEmails' runat='server'> <option value="test@test.com">TEST</option> </select><span id='SelectMsg'></span> What needs to be changed in my code to make this operate correctly?
I have a normal winform and I would like to know is there any possibility to generate a html page and to add a css file to the html page from the local folder.
I have a program that will use a lot of panels. The panels will all be on top of each other. Then if you clicked an option on one of the panels it would cause another panel to come up and so on. This is a game so it's not like the panels come up in a set order each time. Depending on what the use selects a different panel could come up in a different order.
z-order or hiding Z-order is supposedly a nicer way to do it instead of hiding so i was going to try that, but sometimes when a panel comes up it has info from another panel on it or the panel doesn't show at all and other things like that.Is there a way i could send all panels to back and bring only the panel i want to front other than doing something like..
We have two update panels on our webpage. Now first update panel is having button cancel. While second update panel is having a file upload control.Now if the user uploads a file that is going to upload in about 2 mins, and in between, say after 30 seconds the user clicks the cancel button, the upload taking place in update panel 2 should stop.
So I'm NOT trying to programmatically hide panels.
I have a LOT of panels within my program. I programmatically position and show/hide them based upon user input.
The problem is there are so many panels it's making it hard to work on them to add content, buttons, checkboxes, etc. I need a way to make them not show in the VB IDE.
I am using an update panel and when I click a button it will update all the panels. updapanel1.update() is very simple, but my data is not updating unless I hit the button twice. My gridviews shows data for a selected user, and then all the grids reflect that users data. works fine all the update panels work for the gridviews. Now for somereason when i try to do a row count and update the panel with the summary, it does not work, i get either the previous users summary or if i hit update again for the same user i get the correct data.
when i do this, i get the ACTION being called TWICE, what should i do about this?
if i call html.partial instead to just render the control, then i need to specify all the objects/values manually, which i shouldn't need to do this as the ACTION itself takes care of this stuff.
i maeks sense to have both these work together but they don't, what should i do?
I have a grideview that displays rows that will be deleted across servers by the click of a delete button in the footer of the grid. This delete will take a long time so i want an updateprogress bar. I'm not really familiar with it so I don't know where to begin.
I'm amateur with asp and .net, but i need create a page to generate xml/json output response similar to java servlet.what is the best way to do ajax response with asp forms? Asp page form with [code]
I am trying save a value from an input tag in some HTML source code. The tag looks like so:
<input name="user_status" value="3" />
I have the page source in a variable (pageSourceCode), and need to work out some regex to get the value (3 in this example). I have this so far: [Code] Which works fine most of the time, however this code is used to process source code from multiple sites (that use the same platform), and sometimes there are other attributes included in the input tag, or they are in a different order, eg:
I have to submit a HTML form to a 3rd party website and one of the hidden fields is an XML string. The XML needs escaping before it is sent to the 3rd party.
However when I add the plain XML to the form field it semi-escapes it for me. So then when I use HTMLEncode myself part of the XML is double-escaped. How do I prevent the automatic escaping that appears to becoming from .NET.
Or even better how else can send the escaped XML via the hidden field.
I have admin module. This module have one master page which has the no of panels at left side. I have to make this panels visible and invisible with base control class which is constructed in VB language. I'm working with asp.net 2.0 with c# web site.
how do i construct this base control class and manage panels with Master Page on link button click event.
I'm trying to page and sort my DataGrid which is inside a ModalPopupExtender but I can't page it in any way, already tried with <Triggers>, put the UpdatePanel inside, outside, in the middle, and it does NOT work. Modal popup does not get closed but the grid just disappears. Code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Not Page.IsPostBack Then BindData() End If
I'm trying to use an ajax auto complete extender, but it's not working. I put a break point on the GetCompanyNames method in the web service, but it doesn't even hit the break point.
Here is my ajax autoextender <asp:TextBox TabIndex="1" ToolTip="* Required - enter the Company name" ID="txtCompanyName" runat="server"></asp:TextBox> <ajaxToolkit:AutoCompleteExtender runat="server" ID="acCompanyName" TargetControlID="txtCompanyName" ServiceMethod="GetCompanyNames" ServicePath="~/WebServices/AutoComplete.asmx" MinimumPrefixLength="1" EnableCaching="true"> [Code] .....
I am using jquery so using ajax to post data, but for some reason when i click on submit, the page doesnt go from aspx to aspx.vb on the back side.here's my code -
new_class is my webmethod in the vb.net side. Now if i put an alert in the btnsave onclick function, i see the firstname value in the alert. But the page does not call the new_class function after that.
For several days now I've been messing around with Ajax calls using different combinations of javascript, ASP controls, and regular controls. I've gotten a bit of understanding about what's going on, but using ASP controls still hides too much of the machinery, and I want to have a deeper understanding. With that aim, can anyone tell me why the following setup doesn't quite work?I have a file "Testy.aspx" with the following:[code].....
So, I hoped to make my .aspx file do double-duty both as the regular-page request handler as well as the Ajax request handler. However, when I click the button ("baroo") to generate the Ajax request, the result that ends up written back to the "testytext" div is the raw html for the entire page, as if under normal request conditions. Clearly, my attempt to override the page request by making the code-behind implement IHttpHandler and supplying an "Overrides Sub ProcessRequest" method is not working. The server is still treating the Ajax request as a normal request, and in fact my own "ProcessRequest" method is never even called.Is it possible to build a page/handler like this? How can I intercept the incoming request from the client and respond accordingly?This is how Ajax works, right? So it must be possible.Again, I'm deliberately doing this as an excercise to avoid the use of "magic" ASP controls like UpdatePanels,
I'm not sure what's wrong with the following setup. I have a View that lists a number of records, and each has a dropdown associated with it to change a value on that record. I had it all working without AJAX, but you had to change a bunch of the dropdowns then click a Submit button. I wanted to change it so that it would save the dropdown choice immediately.
My stripped down View (of type IEnumerable(Of MyTable)):
What I would like to happen is for the dropdown change to trigger the Update controller, but probably not return anything - just update the database and let the user move on. What's happening though is that a blank page is displayed with the Content value on it (i.e. "123: ABC"). It's the correct id/code combo, so the Update seems to be firing correctly, it's just choosing to wipe out the html.
I am using $.ajax call for download excel from .aspx page. But ajax throwing an error after Response.End. This is the code I used. Control is processing till Response.End() then alert(textStatus); giving parser error.

I have an asp.net gridview that is originally bound to a sqldatasource control, but when the user presses an external button, it instead gets the contents of a datatable rather than a SQLdatasource control. I therefore had to write code in the PageIndexChanging event of the gridview to allow for paging. My code is as follows:
Protected Sub gvEvents_PageIndexChanging(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewPageEventArgs) Handles gvEvents.PageIndexChanging
gvEvents.PageIndex = e.NewPageIndex
gvEvents.DataBind()
This worked beautifully until I added an AJAX update panel so the whole page wouldn't postback every time it paged, and paging stopped working. I debugged it and discovered that it is actually calling the PageIndexChanging event, but nothing is happening. I searched the web and found a few people with the same problem, but their solutions did not work for me. There was one on this site whose problem was solved by the following:
In PageIndexchanging event, where you bind data to grid, make sure, data is again fetched from the DB
I don't know what that means; my data was being bound as demonstrated above. I have "enable paging" set to true and EnableSortingAndPagingCallbacks set to false.
I am including my markup for the updatepanel below.
