I would like to change the link that has been clicked, to class="active". I would like to add a class to the div if the page above is clicked too.
If (Len(Request.QueryString("pageid")) <> 0 and Request.QueryString("pageid") = 4) Then
menu & Request.QueryString("pageid") & .Attributes.Add("class", "active")
link & Request.QueryString("pageid") & .Attributes.Add("class", "activelink")
end if
I have a menu in a user control with a sql database datasource. From what I have read online, the staticselectedstyle will only work if the menu control has a datasourceid defined. Here's what I have so far:
Using VS 2010 RC, VB, I have a label on a masterpage that is hidden. I want to make it visible from a content page when needed, and have the text change on the label as well from the master page.
I am using the following to access the label, but the text and other properties don't change for some reason.
Dim lblErrorMessage As Label lblErrorMessage = CType(Master.FindControl("lblErrorMessage1"), Label) lblErrorMessage.Style.Add("display", "inline") lblErrorMessage.Text = "LoginID ALREADY EXISTS!!! Please choose a different ID"
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 ?
In my aspx page, I have a number of drop down controls. I would like to update an attribute on each of the controls with "class=leftColumn" with the following line: propertyID.Attributes["nameOfAttribute"] = "false"; But instead of manually writing out each controlID and setting its attribute with the line above, I had hoped there was a way to go through and set the attribute on each control ID if it had class=leftcolumn. This is something I know is very easy with JQuery, BUT I need to do it with the code behind (C#) I was told this is not possible (i.e. to acquire a list of all the controls and then iterate through the list and give it the attribute or any other way. That manually setting each control like the above example is the only way in ASP.NET.
have some code which dynamically generates a number of drop down lists to provide the user with different options. The items in these drop downlists contain a value which is a unique id for that particular combination of options and a text component which just plain text but not neccessarily unique. I then have assigned a handler to these dropdownlists which is called on selected index changed to perform the relevant actions based on what options are selected. The problem is to make the system perform the correct action I need the unique ID from selectedValue of the drop down box but when it posts back it appears the selectedValue has been replaced to match the text of the item.
Dim dynDdl = New DropDownList() dynDdl.ID = "ddlOpts" & i dynDdl.AutoPostBack = True AddHandler dynDdl.SelectedIndexChanged, AddressOf dynDdl_selectedIndexChanged [code]...
I am thinking that it would be better to use multipe CSS files and change them within the master page dynamically than it would be to use multiple master pages (basically one master page for each page, which defeats the purpose of the master page).
However, I do not know how to make a change to the master page before a standard apsx page that is derived from it is loaded.
i want to add items to a gridview in asp.net from a custom class. The class has Properties X and Y. Does anyone know if im able to add special attributes to these properties so i can just add the class and not have to muck around?eg..
I have a gridview, and I want to change the backcolor of any row that has the column checkedin = false.
I have this working fine, except that it will not change the backcolor of the first row and only the first row. Matter a fact if I sort the columns by clicking on the header rows the order changes and the backcolor highlights the row that was the first row before it was sorted so long as it is not the first row. I actually removed all formatting from my gridview and still the same issue.
I know this is kind of obsessive, but is there a way to control the order that the TagBuilder class renders the attributes of an HTML tag when you call ToString()?
i.e. so that
var tb = new TagBuilder("meta"); tb.Attributes.Add("http-equiv", "Content-Type"); tb.Attributes.Add("content", "text/html; charset=utf-8"); tb.ToString(TagRenderMode.SelfClosing)
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 am using master pages standard theme is vs 2010, have few tabs and they all open different pages. wondering if any body knows how to change the colour of tab after the tab is clicked. will be useful to identify page for user.
I've tried setting the <pages pageBaseType="DynamicWebPage" /> value in web.config, but when I response.write out the page type, I'm still getting Microsoft.WebPages.WebPage.
I'm simply trying to sub-class WebPage and add some additional functionality such as a dynamic PageData dictionary similar to Phil Haack's dynamic ViewData dictionary.
I have been trying to add validation attributes dynamically at runtime and all works ok. I next tried to add a DisplayAttribute at runtime hooking into the same
I have found hints that MVC 2 recognises the 'buddy class' type of property metadata, where data annotation attributes are applied to a 'buddy' metadata class, and the MetadataType on the actual entity class points to that buddy class, as below. However, as below, it seems the only attribute that makes any difference to the rendered UI is DisplayName. Why are the other attributes like DataType, Required, and ReadOnly not working? I.e. why can I enter text in a read only field? Why do I not get an error when a required field is empty? Why does the DataType attribute have no apparent effect? Why does EditorForModel not include validation messages?
[MetadataType(typeof(CustomerMetadata))] public partial class Customer { public class CustomerMetadata { [ScaffoldColumn(false)] public object CustomerId { get; set; } [DisplayName("CustomerNo.")] [ReadOnly(true)] [Required(AllowEmptyStrings = false, ErrorMessage = "Customer No. is required.")] public object CustomerNo { get; set; } } }
I find behaviour the same whether I use an explicit LabelFor and TextBoxFor for each model property, or a single EditorForModel for the whole model.
Im trying to create a "user control menu" where links to a page's usercontrols are placed at the top of the page. This will allow me to put several usercontrols on a page and allow the user to jump to that section of the page without scrolling so much. In order to do this, I put each usercontrol in a folder (usercontrols) and gave each control a Description property (<%@ Control Language="C#" Description = "Vehicles" .... %>).
My question is how can I access this description dynamically? I want to use this description as the link in my menu. So far, I have a foreach on my page that looks in the ControlCollection for a control that is of the ASP.usercontrols type. If it is I would assume that I could access its attributes and grab that description property. How can I do this? (Im also open to a better way to achieve my "user control menu", but maybe thats another question.) Should I use ((System.Web.UI.UserControl)mydynamiccontrol).Attributes.Keys?
Using VS 2010, RC, VB, how do I change the subfolder attributes. When I publish and choose to delete all the files and folders, I have to recreate the security levels for them manually. I assume that I can have Web Config do that for me.
I have a label, let's call it LblA. I have a SqlDataSource, let's call it sds. Now, I have selected out and managed to get specific values using the select function. I want to set LblA's text to the value selected out of sds. I need this to occur every 5 (or as many as I specify really) seconds. I orignally used a timer object, however, for any of you who have used the timer object before, it likes to refresh the page, this makes it very hard to navigate off of the page; not only that, it's sloppy. Does anybody know a way to easilly update LblA's text from sds without refreshing the actual page.
I've read around and came to the conclusion that I need to use ajax, err... jQuery. However, I really don't know anything about the two except that they are both Javascript libraries?
