IE11 Incorrectly Rendering HTML5 Tags
Feb 22, 2015I have created a Default.aspx page using HTML5 tags such as header, nav, section, footer.
1. The content renders fine on my dev machine (running IE11).
2. However, it doesn't render on my network (live client) PC running IE11. But, it is fine rendering in Chrome!!!!
Here is an example:
Code:

Forms Data Controls :: Gridview Tags Not Rendering After Postback?
Dec 17, 2010I am having an issue with the gridview in ASP.NET. Everything works well when running from IDE in both debug and without debug. When I publish to IIS I have a gridview that I use in two places. It works fine in one place but not the other. In one instance I am using an IFRAME tag to display the page that uses this data grid. When I first load it it works fine, I can click on a row. But after clicking on that row after the first postback, I can no longer get it to postback again on future clicks. I used firefly and after clicking the first time on the grid, the tags for the table are not rendered though I can clearly see the grid. Confused... Here is the rendered code before clicking on it using firefly. (oh yea, this gridview is also inside of an updatePanel) (In the below I replaced actual data with xxxx)
[Code]....
Below is the code after clicking on the grid.
<div id="UpdatePanel1">
<div style="background-color: white; width: 818px; height: 405px; overflow: auto" onscroll="GetScroll()" id="divFill">
<div style="padding-bottom: 5px; background-color: buttonface; width: 818px; height: 20px; padding-top: 5px" id="NavFoot" align="right">
</div>
Also, if I did not provide enough information let me know.

Render - Server Control Emitting Server Side Tags?
Feb 19, 2010I'm new to writing custom ASP.NET server controls, and I'm encountering the following issue:
I have a control that inherits from System.Web.UI.HtmlControls.HtmlGenericControl. I override the control's Render method, use the HtmlTextWriter to emit some custom HTML (basically a TD tag with some custom attributes), and then call the case class' Render method.
Using the control:
<dc:Header id="header1" runat="Server" DataColumn="MemberNumber" Width="30%">Member Number</dc:Header >
The problem is that when I view my rendered HTML, the server tag is emitted to the client as well (right after the TD tag):
<dc:Header id="ctl00_ContentPlaceHolder_testData1_testData1_header1">Member Number</dc:Header>
How do I prevent this from happening?

View 2 RepliesC# - Forum Tags: Can Regex Be Modified To Grab Nested Tags?
Feb 24, 2011I am building a forum and I want to use forum-style tags to let the users format their posts in a limited fashion.Currently I am using Regex to do this.As per this question:How to use C# regular expressions to emulate forum tags. The problem with this,is that the regex does not distinguish between nested tags.Here is a sample of how I implemented this method:
public static string MyExtensionMethod(this string text){return TransformTags(text);}
private static string TransformTags(string input)
{string regex = @"[([^=]+)[=x22']*(S*?)['x22]*](.+?)[/(1)]";
MatchCollection matches = new Regex(regex).Matches(input);
for (int i = 0; i < matches.Count; i++)
var tag = matches[i].Groups[1].Value;
var optionalValue = matches[i].Groups[2].Value;
var content = matches[i].Groups[3].Value;
Now,if I submit something like [quote] This user posted [quote] blah [/quote] [/quote] it does not properly detect the nested quote.Instead it takes the first opening quote tag and puts it with the first closing quote tag.Do you guys recommend any solutions?Can the regex be modified to grab nested tags?Maybe I shouldn't use regex for this?

Feb 4, 2010I am outputting the entire HTML for my server control as follows:

myStringBuilder is a StringBuilder object that is manually built in a separate private method.Is this an efficient way to do it? Or is it better to pass the HtmlTextWriter to my private method and make multiple calls to HtmlTextWriter.Write()?

C# - Server Tags In Markup?
Feb 4, 2011Morning all I have frequently used the old
<asp:Label ID="lblWas" runat="server" Text='<%# XPath("FACEVALUE") %>'></asp:Label>
This type of thing. when I first came across it I loved it, i'm using it again today but not quite so simply. I have a number of extra things I would like to achieve.
Apply formatting to the value. Like Text='<%# string.Format(XPath("FACEVALUE"), "{0:c}") %>'>
<asp:LinkButton ID="lnkBook" runat="server" PostBackUrl='/THEATRE/' + XPath("FACEVALUE")>Book</asp:LinkButton>
For option number 2 the URL is not as I would expect, and for number 1 I cannot get the syntax correct if it's even possible.
I have not been able to find something suitable in google. Hopefully what I am trying to achieve is obvious from the example :)

How To Apply CSS Tags To <li> Tags When Using 4.0 Menu Control
Feb 1, 2011Is there a way to apply your own CSS tags to <li> tags when using ASP .NET 4.0 menu control? For example, say I have an external style sheet that has tags "class1", "class2", "class3", and etc. I want to apply "class1" to the first menu item. Then if menu item is selected, I want to apply "class2" and if it's not selected, "class3". I played with various 'Static' styles, but just can't get it work. I finally gave up and created my own menu control that extends ASP .NET menu control and provides my own custom rendering. This works, but I'm wondering if there is a way to get it work with built-in menu control.

Custom Rendering Logic On Server Side + MVC + Ajax?

Now what I do today is I just have a form below and I do a post and add the item and return the same view. My question is - how to do it with ajax? Should I create a control and return HTML a'la winforms? Is that sexy? How do you do something like that? Or should I drop it? Maybe duplicate the rendering logic with javascript?

Server Removes Spacing Between Head Tags
Jun 11, 2010I 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." />
<meta name="keywords" content="lawn cutting, lawn mowing, lawn care, fertilizing, aeration, mulching, shrub trimming, lawn mowing, edging, pruning, mulching, weed control, waukesha, Brookfield, Pewaukee, menomonee falls" />
<title>Lawn Care Waukesha — Cut My Lawn, Lawn Care Service</title>
<link rel="shortcut icon" type="image/x-icon" href="favicon.ico" />
HTML after being processed by the sever, with all the tags running together:
HTML Code:
<head><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!

MVC :: Whitespace Stripped Between Server Tags In View?
Jun 28, 2010I'm rendering a view for the text/plain part of an e-mail. But in some cases, the whitespace is removed between non-output server tags, and I can't figure out why. Can someone explain why the following is missing the line breaks before the final line of output?
[Code]....
But this works - whitespace is preserved between output tags:
[Code]....
This is on MVC 2. It may have been on MVC 1 (or even in Web Forms), but I didn't notice it until today when I went to add a new line to the e-mail, so not sure of the source. Does ASP.NET or MVC have some optimization to try not to output whitespace between server tags?

here is the code
protected string CreateSubSystem(string id, string roles, string AnonymousTemplateClass, string href, string rolesContentTemplateClass, string LoggedInTemplateClass)
{
StringBuilder sb = new StringBuilder();
sb.Append("<div class="SubSystemIconPlacement" id="");
sb.Append(id);

sb.Append(id);
sb.Append(""><AnonymousTemplate><div class="");
sb.Append(AnonymousTemplateClass);
sb.Append(""></div><asp:Label ID="lblDisabled");
sb.Append(id);
sb.Append("" runat="server" SkinID="OneColLabel" meta:resourcekey="lbl");
