I have two repeaters bound to object collections. They both work fine. But when I move repeater B to repeater A's FooterTemplate the serverside declaration of repeater B disappear.This is not a parent/child relation.
Update:<asp:Repeater ID="myOuterRepeater" runat="server">
<ItemTemplate>

I have been developing in C# for a while. But I have never had the need to develop a web application now I have the need.
I have opened a project with asp.net webapplication and created the first form which I can get to display in my explorer.
Now I need to be able to click on a button, close the current form and move to the next form I will move data between the forms once I can get the form open.my normal c# code would be something similar to this.hide(); newform _newform = new newform();_newform.show();
How do I do this in a webpage (using asp.net).
Having an issue with some form validation. Everything works great right up untill I add a postbackurl to my button. Any ideas on how I can make my form check validation before the postbackurl is used?
The page has three "forms" on it (not form tags though), this is an example of one of them (not tidy yet as I do that when it works!)

What am I missing here?I get the error Declaration Expected @ myPostData=
[Code]....
Dim encoding As New ASCIIEncoding()
Dim RateXML
As
String =
"123"
'Format the Data
Dim myPostData
As
Byte()
myPostData = encoding.GetBytes(RateXML)

I am using a "Detail View" to edit the data in my "Customer" table. The fields are "CompanyName", "ContactPerson", "StreetAddress", and "City". If I type data into the first field ("CompanyName") and then press the "tab" key, control moves to the second field "ContactPerson". However, if I type data into the first field ("CompanyName") and then press the "Enter" key, instead of control moving to the second field ("ContactPerson") the program closes the form.
Is there someway that I can control the action of the "Enter" key so that this will not happen?
Also, is there any way that I can have control move from the first field ("CompanyName") to a field other than the seconc field ("ContactPerson") if the content of the "CompanyName" field contains the value "Internal"?
If I have something like:
lbl1.Text = "lbl7.Text = "Blah blah text <A href="long URL">here</a>.""
Then it comes up with an error. I tried escaping the quotes but still doesn't work so what do I do?
I have an AJAX NumericUpDown Control that takes a decimal. If I put in 1.30, it removes the zero. I do not want to remove the zero, it must remain at 1.30.
A demo of this can be found here: [URL]
For example, enter 1.30 in the text box then tab out or click somewhere else. The zero is removed.
I have an ASHX handler or an ASPX page (the problem happens in both cases).
The web client sends a request containing If-None-Match and/or If-Modified-Since headers but context.Request.Headers.Get("If-None-Match") or context.Request.Headers.Get("If-Modified-Since") is null in the handler.
The same script works in my local development machine but it doesn't work in the online machine (both are running IIS7 on Win 2008, .NET 3.5)
I have some weird problem. We're using Windows Server 2008 R2 x64 (8 Cores and
8 GB RAM) with IIS 7.5 and ASP.NET MVC 2.
I always cache (simple) stuff via the context cache and it seems like 9 out of 10 immediate page refreshs the Cache["MyKey"] is always null, even though there's no memory limit set on the pool and the server has lots of free memory.
I add expiring data via:
[Code]....
When just doing: Cache.Insert("MyKey", myObject); or Cache["MyKey"] = myObject; I get the same result (cache is almost always null for that key).
As you can see I added a callback, which writes the CacheItemRemovedReason to a text file, and the text file says CacheItemRemovedReason.Removed for MyKey. The doc for CacheItemRemovedReason.Removed says, that I call Remove/Insert on it, even though in my whole project there's no "Remove"-calls, just simple if(Cache["MyKey"] == null) {Cache["MyKey"] = ...} stuff.
I tried adding:
<caching><cache disableMemoryCollection = "true" disableExpiration = "true" privateBytesLimit="0" percentagePhysicalMemoryUsedLimit="90" privateBytesPollTime="00:02:00" /></caching>
to my web.config file in the System.Web-section but nothing changed :(
why Cache["MyKey"] is almost always null?
What is a Generic Class Declaration? and when should it be used?
View 2 RepliesI am working on a existing web application which I load from a folder. I mean application semms it is not created as website application from visual studio.
The controls defined in aspx are not having member declarations in .aspx.cs file and no designer.cs files were created. I mean nowhere controls are defined, but simply the controls defined in aspx are accessble in corresponding aspx.cs file wich same id of the control tag. those are being reconized even in intelligense.
How is it possible? is there any special configuration needed to make aspx controls declared automatically for aspx.cs file use.
How do I allow nullable string to my declaration?

I have added one div in aspx page and i want to take the Id of that div in code behind file by using webcontrol.
View 1 RepliesI haven't been able to find relevant information through searches. I'm very green when it comes to sever side scripting. I have an ASPX page with a standard form. In the head I have meta tags, the title tag, and a link tag neatly ordered on their own lines. However, when viewing the source code after publishing to the server, the spacing between the tags is removed and it looks quite messy. (There are also <style> and <script> tags that follow, but they remain unaffected.)
I realize this has no practical effect on the site itself (in an SEO sense or otherwise). My project manager shows the source code to our clients to educate them on meta tags and page titles. It would help if it wouldn't become jumbled like this. I wonder if this is a common issue and if it's possible to prevent through better coding practices. HTML as authored, with tags separated on their own lines:
HTML Code:
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta name="description" content="Welcome to Lawn Care Waukesha - Cut My Lawn. Cut My Lawn - Lawn Care Services has offered quality lawn cutting, fertilizing, aerating, and much more at affordable pricing since 2002! We currently offer lawn care service to Waukesha, Brookfield, Pewaukee, Menomonee Falls, and surrounding communities." />

I'm not sure it's relevant, but here's the script used to send the form (which I didn't write, by the way). It's the final tag inside the page head:

How to make a build in VS 2010 within an ASP.NET MVC application that would remove all of the source code (CS and VB) files? When I build a website or web app I usually copy the contents of the entire solution to the hosting server. Mostly clients get the source but sometimes I do not want to expose the source to the hosting server thus only the Public (or Content) folder, views, masters and the built DLL should be copied.
Manual solutions are not applicable. What do you guys use?
What I'm interested in is a regular expression that will accept HTML input and remove all attributes inside the tag while leaving the tag intact. For example I want this...
<p class="test" id="TestParagraph">This is some test text right here.</p>
To become this...
<p>This is some test text right here.</p>
I face this weird problem when I was trying to add multilanguage support to my website.The main login page contains user control and I am also using Master page. I added a linkbutton to master page so I can switch to other language from any page. So, whenever I want to switch langauage, I check this linkbutton text value. so I use this code
LinkButton lb = (LinkButton)Master.FindControl("languageLinkButton");
(Note: this code written inside protected override void InitializeCulture() in mainpagelogin.aspx)move the above line everything run normally.
am using this function to remove whitespaces at html output. i had to put if else otherwise page was giving error afterasynchronous postbacks. now it works fine.is it possible to make it work also after asynchronous postbacks ?also is it possible to make this regex function also removes new lines ?like how google doesthere is no line at their source codes

As pointed out in the question:
EmptyDataTemplate and EmptyDataText not working in GridView
using CSS-Friendly Control Adapters removes the data that would would be populated by EmptyDataTemplate or specified in EmptyDataText in GridView. One of the solutions is to disable the addapters for GridView components as specified in this answer Is there a solution, that would allow to keep the use of CSS-Friendly Control Adapters for GridView and still take advantage of EmptyDataTemplate functionality?
I am creating an HTML document using HTML agility pack. I load a template file then append content to it. All of this works, but when I view the output file it has removed the closing tag from my <br/> tags to look like this <br>. What is causing this?
Dim doc As New HtmlDocument()
doc.Load(Server.MapPath("Template.htm"))
Dim title As HtmlNode = doc.DocumentNode.SelectSingleNode("//title")
title.InnerHtml = title.InnerHtml & "CEU Classes"
Dim topContent As HtmlAgilityPack.HtmlNode = doc.GetElementbyId("topContent")
topContent.InnerHtml = html.ToString
doc.OptionWriteEmptyNodes = True
doc.Save(outputFileName, Encoding.UTF8)
More info:
It was removing my closing image tags, after I added doc.OptionWriteEmptyNodes = True, it quite doing that.
I tend to use a lot of commenting in my code. All these comments slow down the page rendering.
What I'm looking for is a script of some sort that goes through all aspx and cs pages in my web project and removes the commenting.
Note
In aspx pages I use commenting like this:
<%--
and
<!--
in cs pages I use
//
sometimes this
/*
Hope to get some easy and nice tips/scripts.
I have an updatepanel in my content page with a timer which re-renders the updatepanel every 5 seconds.I also have a textbox outside of this updatepanel in my masterpage.Whenever the timer ticks, focus is lost from my textbox. What possible reasons are there for this happening?
