How can I find all tags which have any attribute starting with some character?Something like ('TR[^a]) Here I am trying to find all TR which have any attribute starting with 'a'
View 2 Replies to directly get all elements in a form who contains a non html attribute ?
<input .... customAttribute="validateMe">
So I could find all input elements that will require validation.And use this in a loop to add validation to the input's found :
$('input').attr("customAttribute").val() == "validateMe"
I could also write every validation for each object separately, I have only a few elements who uses a required validation but it would be nice that I could do this in one shot instead of repeating the $("input").rules("add .....
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 have a fck editor in which the user enters some text. And in the code i want to strip the class,id attributes of the text posted. I know this can be done through regular expressions And i have written some code to do so but unfortunately it's not working.
private string RemoveScripts(string input)
{
string re1 = "(.*?"; // Non-greedy match on filler
string re2 = "(class)"; // Word 1
string re3 = "(=)"; // Any Single Character 1
string re4 = "(".*?"))"; // Double Quote String 1
string re5 = "(id)";
Regex regClass = new Regex(re1 + re2 + re3 + re4, RegexOptions.IgnoreCase | RegexOptions.Singleline);
Regex regID = new Regex(re1 + re5 + re3 + re4, RegexOptions.IgnoreCase | RegexOptions.Singleline);
input = regClass.Replace(input, new MatchEvaluator(ReplaceClassID));
input = regID.Replace(input, new MatchEvaluator(ReplaceID));
return input;
}
private string ReplaceClassID(Match m)
{ return ""; }
i have a long string dat can contain html tags. applying htmlencode will encode all the tags. but i want this method to leave some specific tags intact
View 3 RepliesI am trying to get the pixel color of a mouse click event. (meaning when the user clicks on the page I need to identify what color he just clicked on.) I believe the best way to go about this is to create a screen cap of the browser contents then use image.GetPixel sending the x,y locations. The only part of this that I am having issues with is creating the screen cap at "click-time." It would be easiest for calculations if i could get a screen cap of the entire contents of the browser, but I could also work with being able to screen cap a specific div element by ID.
I have experimented with this using an actual image on the page and i can get the correct values however, the page will not be an image so i need to create the screen cap...
If you have any information about how to do this or have a better way to get the color of the pixel clicked on by a user.
I'm currently using ASP.NET MVC 2 and the spark view engine. The main master page (application.spark) contains all of the CSS link tags that need to be present for all pages (global stuff). However, I have some content pages that have page specific CSS tags and currently I'm just sticking the link tag in the body as something like:
<content name="MainContent">
<!-- page specific csss -->
<link rel="stylesheet" href="/Content/css/page_specific.css" />
My problem is that when the page renders, this tag ends up in the which is not where it needs to be. Is there a solution for this?
I had was to check the controller in the Application.spark page and write out which page specific css file is required for that particular controller, however, that solution doesn't seem to scale well and I would imagine there is some way of creating the link in the child page and having it render where it's supposed to by the browser.
i'm trying to find all the anchor tags and appending the href value with a variable.
for example
<a href="/page.aspx">link</a> will become <a href="/page.aspx?id=2">
<A hRef='http://www.google.com'><img src='pic.jpg'></a> will become <A hRef='http://www.google.com?id=2'><img src='pic.jpg'></a>
I'm able to match all the anchor tags and href values using regex, then i manually replace the values using string.replace, however i dont think its the efficient way to do this.Is there a solution where i can use something like regex.replace(html,newurlvalue)
I'm currently writing a web app in ASP.NET MVC 1.0 (although I do have MVC 2.0 installed on my PC, so I'm not exactly restricted to 1.0) -- I've started with the standard MVC project which has your basic "Welcome to ASP.NET MVC" and shows both the [Home] tab and [About] tab in the upper-right corner. Pretty standard, right? I've added 4 new Controller classes, let's call them "Astronomer", "Biologist", "Chemist", and "Physicist". Attached to each new controller class is the [Authorize] attribute. For example, for the BiologistController.cs
[Authorize(Roles = "Biologist,Admin")]
public class BiologistController : Controller
{
public ActionResult Index() { return View(); }
}
These [Authorize] tags naturally limit which user can access different controllers depending on Roles, but I want to dynamically build a Menu at the top of my website in the Site.Master Page based on the Roles the user is a part of. So for example, if "JoeUser" was a member of Roles "Astronomer" and "Physicist", the navigation menu would say:
[Home] [Astronomer] [Physicist]
[About]
And naturally, it would not list links to "Biologist" or "Chemist" controller Index page. Or if "JohnAdmin" was a member of Role "Admin", links to all 4 controllers would show up in the navigation bar. Ok, you prolly get the idea... Now for the real question... Starting with the answer from this StackOverflow topic about Dynamic Menu building in ASP.NET, I'm trying to understand how I would fully implement this. (I'm a newbie and need a little more guidance, so please bare with me.) The answer proposes Extending the Controller class (call it "ExtController") and then have each new WhateverController inherit from ExtController.
My conclusion is that I would need to use Reflection in this ExtController Constructor to determine which Classes and Methods have [Authorize] attributes attached to them to determine the Roles. Then using a Static Dictionary, store the Roles and Controllers/Methods in key-value pairs. I imagine it something like this:
public class ExtController : Controller
{
protected static Dictionary<Type,List<string>> ControllerRolesDictionary;
protected override void OnActionExecuted(ActionExecutedContext filterContext)
{
// build list of menu items based on user's permissions, and add it to ViewData
IEnumerable<MenuItem> menu = BuildMenu();
ViewData["Menu"] = menu;
}
private IEnumerable<MenuItem> BuildMenu()
{
// Code to build a menu
SomeRoleProvider rp = new SomeRoleProvider();
foreach (var role in rp.GetRolesForUser(HttpContext.User.Identity.Name))
{
}
}
public ExtController()
{
// Use this.GetType() to determine if this Controller is already in the Dictionary
if (!ControllerRolesDictionary.ContainsKey(this.GetType()))
{
// If not, use Reflection to add List of Roles to Dictionary
// associating with Controller
}
}
}
Is this doable? If so, how do I perform Reflection in the ExtController constructor to discover the [Authorize] attribute and related Roles (if any) ALSO! Feel free to go out-of-scope on this question and suggest an alternate way of solving this "Dynamic Site.Master Menu based on Roles" problem. I'm the first to admit that this may not be the best approach.
I m using ASP.NET and access as back end. I want to fatch a record between two specific date for that i
private void btnsearch_Click(object sender, EventArgs e)
{

string str = "select Date1,Item,Rs,Payment from Books where Date1 BETWEEN '" + dateTimePicker1.Text + "' AND '" + dateTimePicker2.Text + "'";
cm = new System.Data.OleDb.OleDbCommand(str, cn);
System.Data.OleDb.OleDbDataReader r1;
r1 = cm.ExecuteReader();
while (r1.Read())
{
dataGridView1.Rows.Add();
dataGridView1.Rows[i].Cells[0].Value = r1[0].ToString();
dataGridView1.Rows[i].Cells[1].Value = r1[1].ToString();
dataGridView1.Rows[i].Cells[2].Value = r1[2].ToString();
dataGridView1.Rows[i].Cells[3].Value = r1[3].ToString();
i++;
}
cn.Close();
}
but it gives error Data type mismatch in criteria expression. table name is "book" fields are date1,item,rs,payment

I am accessing this xml file by using LINQ to XML in asp.net by using C#. I am able to access all the attributes of an XML node by explicitly specifying the name of the attribute. I want to write query on this xml file which reads all the attribute values of the xml node (In our example the node is SERVER) dynamically means I want to write the query which can read the read the value of the attribute Name & ID from first node, only name from second row, Name, ID & Parent from the third row , Name & ID from the fourth row, Name, Parent & Value from the fifth row & only Name from the sixth row without modifying the existing code every time. Once I add one of the attribute ( for example if I add the attribute ID in the sixth row ) in the above xml file then I dont need to modify my LINQ to XML query. My query should dynamically fetch the total number of attributes & display their values. Is their any way to do this ?

I want to implement readmore/less feature. i.e I will be having html content and I am going to show first few characters from that content and there will be a read more link in front of it. I am currently using this code :
var txtToHide= input.substring(length);
var textToShow= input.substring(0, length);
var html = textToShow+ '<span class="readmore"> … </span>'
+ ('<span class="readmore">' + txtToHide+ '</span>');
html = html + '<a id="read-more" title="More" href="#">More</a>';
Above input is the input string and length is the length of string to be displayed initially. There is an issue with this code, suppose if I want to strip 20 characters from this string:
"Hello <a href='#'>test</a> output", the html tags are coming between and it will mess up the page if strip it partially. What I want here is that if html tags are falling between the range it should cover the full tag i.e I need the output here to be "Hello <a href='#'>test</a>" . How can I do this?
Existed MyControl1.Controls.OfType<RadioButton>() searches only thru initial collection and do not enters to children.

I have a gridview with a nested placeholder in each rows. I nested some checkboxes in each placeholders in each rows dynamically, so their ServerIDs are not the same (I dont want to use nested gridview). at the end in a button event I want to count checked checkboxes in gridview while I can not use findcontrol() method in each rows to find checkboxes due to their different ServerIDs.

View 2 RepliesI 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?
i designed a gridview and innergridview. design seems below
Master Data

i have some hidden control in the master record, in child row when i click an link button then i want to read that hdden value so, i use below code var data1 = closestTR.find('input:hidden[id$=hdnData1]').val(); but its not working , the same code is working with the event from Master Record. may i know how to read that master row record from the child row using jquery.? for this master and child row concepts i used below syntax
<gridview>
<HeaderTemplate>
<table>
<tr><td>This is for Master Row Header</td></tr>
</table>
</HeaderTemplate>
<ItemTemplate>
