can i set such property in the markup of ASP.NET page? and how?
i mean something like <uc1:CustomControl Parameters="?"
Is there a way that I can extend asp.net to accept the markup
<c:MyControl runat="server" MyList="1,2,6,7,22" />
Where MyList is a List<int> or List<string> or even List<someEnum>?
So I want asp.net to parse automatically all lists (that can be parsed) generically.
I know I could take the way around it and make MyList a string, then parse that into a list, but then I just end up with more properties than I want tbh.
I've seen various controls in ASP.NET with "collections" of objects, which you can use markup to define. For example:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<Triggers>
<asp
/Triggers>
</asp:UpdatePanel>
In the above example, you can add any number of triggers, and they can be of any type that extends UpdatePanelTrigger. I'd like to do something similar, but with only a single item instead of a collection
I have a CheckBoxList in my page, with the DataTextField and DataValueField attributes set, is there an attribute that I can use to specify a property that indicates if it should be checked?
I'm hoping to just set the datasource, and not have to have any code behind to set the checked property. Possible?
I'm new to ASP.NET and can't figure out how to accomplish this...My code (that needs fixing):
<asp:HyperLink runat="server"
NavigateUrl="~/EditReport.aspx?featureId=<%= featureId %>" />
featureId gets defined as an integer in the backing code. I want href's like...
/EditReport.aspx?featureId=2224
...but instead I am getting...
/EditReport.aspx?featureId=<%= featureId %>
I have an ASCX that inherits from a WebControl that has a 'CustomConfiguration' property of type CollectionConfigurationItem. This configuration gets set elsewhere in the code, so by the time it gets to the ASCX it is set up to how I wish to use the data. At this point I'd like to render out another control using this configuration, like so:
<modules:DataModule runat="server" CustomConfiguration="<%# Model.CategoryListConfiguration %>" />
However, breaking into DataModule always results in 'CustomConfiguration' being null, which is the default value for the property. I've tried adding a Bindable attribute to the property but to no avail, and when I set an EventHandler for the DataBinding event on the DataModule it doesn't even get called.
How can I set this custom-class-typed property from the markup or, failing that what's the second-best method of getting this to work?
I have an asp.net repeater control with a series of asp:hyperlink's
<asp:HyperLink runat="server" ID="name" NavigationUrl="~/Pages/display.aspx?fileid={0}&user={1}" />
and then on the OnItemDataBound method:
fullname.NavigationUrl=string.Format(name.NavigationUrl, user.fileid, user.userid);
So that gives me a series of URLs in the repeater:
[URL]
OK, so with a simple proxy tool someone can replace either of the parameters with some OTHER number to get access to what they shouldn't see.
server-side validation and authentication aside, is there a better method other than passing parameters when trying to create a dynamic URL within a repeater?
I created a UserControl and added a public DateTime property. I want to set this property in Markup (ie. <cc1:MyControl runat="server" id="MyControl1" DateTimeProp="1/1/2010" /> ) however I live in a place with a dd/mm/yyyy date format so it complains if I set something like "20/1/2010". Is there a way to set markup in my local datetime format or do I have to conform to "mm/dd/yyyy"?
View 2 RepliesI have a web application with a Master Page, two pages in my project needed to be out of the master page template and display different styles so I indicated the folder that contains the style sheets for each one of my pages like this:
<%@ Page Language="vb" AutoEventWireup="false"MasterPageFile="~/Site1.Master" CodeBehind="Welcome.aspx.vb"
Inherits="B0_1.Welcome" StylesheetTheme="Default" %>
(or StylesheetTheme="Print" accordingly) [code]...
App_Themes directory contained only Default
The application runs ok but every time I want to modified something the first time I open the page in the design view shows me the following error:The page contains markup that is not valid when attached to a Master Page correct the problem in the code view
Then I click view code and it is highlighted the wrong section that is always all what is in the ContentPlaceHolderID="head".If I cut this bit, go to the design mode and then go back to the code mode and paste the bit of code again I can see the design mode without problems and switch to the code view as well without problems. It is very anoying and I don't know if it will affect
me in other ways.
So what I'm trying to accomplish is this
[Code]....
The user control has public properties named accordingly and the page has protected properties accordingly which I've verified have the desired values.
For some reason the values are always empty strings or 0s in the usercontrol, no matter what the page property is.
The page markup:
<table style="display: none" id="myTable" runat="server">
<tr>
<td>First Name</td>
<td><asp:TextBox ID="TextBox1" runat="server"></asp:TextBox></td>
</tr>
<tr>
<td>Last Name</td>
<td><asp:TextBox ID="TextBox2" runat="server"></asp:TextBox></td>
</tr>.....
Can we write property in property?IN the page load event we have page property and we can find another page property in that page property.Pls let me know how this is happening

This is as I would expect yet the favicon does not appear. It appears fine on any basic html pages but simply won't on any pages that are based on the master page.

I have created a web user control called Activity. I have defined a public-facing event on that web user control called OnActivityDelete. There is a delete button in the Activity control. When the delete button is clicked, the Activity control fires the OnActivityDelete event. I am using this web user control in a repeater. I assign an event handler to the OnActivityDelete event on the repeater's item data bound event. When I click the delete button for the Activity control, the event fires from the Activity control, but it never hits the event handler in the page that's using the control. (I have stepped into the code with the debugger and confirmed this behavior).
My suspicion is that this behavior has something to do with the fact that the event handlers are added in code behind when I bind the repeater to a datasource, which I only do if the page is not posting back.Is it possible to define the event handler for the Activity control in the markup of the aspx page? If so, will this solve my problem?If not, do I have to bind the repeater and hook up to the events every page load in order to solve my problem (this works, I just tested it), or is there some viewstate trick to getting the events to persist? Markup of Repeater on page:
<asp:Repeater ID="rptrActivites" runat="server" EnableViewState="true">
<ItemTemplate>
<div class="activity">[code]...

If Not Page.IsPostBack Then

I was having a discussion with a co worker about some controls I implemented. He objected to my use of dynamicly instantiating controls in the code behind, because it will be slower than specifying the control in the markup. I thought he was talking about output cacheing which to my understanding only caches the rendered output of a page not the instantiated Page object. He said no its a different type of caching. Unfortunately he was unable to give me any documentation to backup the claim so I am wondering if anyone here has ever hear of any such type of caching, and if so is there any documentation on it that I can refer to.
View 5 RepliesIs it possible to use a session variable in the markup aspx page ?
Cause I have a gridview that use an sqldatasource and in the UpdateCommand I want to include a the session variable : session("username").
Ex :
UpdateCommand="UPDATE departments SET DEP_name = @DEP_name, DEP_active = @DEP_active, DEP_date_stamp = CONVERT (CHAR(8), GETDATE(), 112) + ' ' + CONVERT (VARCHAR(8), GETDATE(), 108),
DEP_user_stamp = <% session("username") %> WHERE (DEP_mnc = @original_DEP_mnc)">
This give me an error :
Server tags cannot contain <% .... %> constructs.
Suppose I'm building a StackOverflow clone using webforms ASP.NET and jQuery. The Question page has a question, several answers, and comments under each. Requirements:Users can post new answers and comments, and edit existing ones, without postbacks. No UpdatePanels; the AJAX calls retrieve just the JSON they need, not HTML fragments. The page loads with all existing answers and comments in place (no javascript needs to run to read the page).
What I'm trying to figure out is how to do this without having to maintain two sets of markup (one that's bound on the client using some form of jQuery templating, and one that's bound on the server using traditional WebForms).
I want to know how the server will process my page that contain:
1- ASP.NET markup mixed with HTML elements.
2- Code behinde.
Will it read the ASP.NET markup line by line and even HTML elements? And then reads the code behind? or what exactly?
to whom it may concern,
I wish to access a public property in a master page from a nested content page
is there anyway to do that without using "master type"
i found this link
http://www.velocityreviews.com/forums/t110057-accessing-properties-from-nested-master-pages.html
but i dont understand what "companywide" is
((CompanyWide)this.Master.Page.Master).HtmlTitle = "now it is working";
i dont want to use "MasterType" i would rather cast..
I have a web page (Orders.aspx) that gets some orders and show them in a Gridview .The orders list I get from DB is depend on a field named Status. The page has a master page that contains a Tab user control. The user control has several tabs and every tab has a different Status. Therefor, when the user clicks on every tab, I want to pass a value as status to my content page (Orders.aspx) and then select the orders from DB based on status.
View 1 RepliesI have user control in the master page. user control code behind page having public property called SetValue.
Now I want to set the value from content page .
In a webforms app, I used to be able to access the master page to hide a link as follows through a property...
protected void Page_Load(object sender, EventArgs e)
{
HeaderFooter m = Master as HeaderFooter;
m.ShowHomePageLink = true;
}
However, when I try this in my MVC View, I can access the property but it doesn't hide the link as expected. It's as if the View is already rendered.
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
<%
MyApp.MasterPages.HeaderFooter m = Master as MyApp.MasterPages.HeaderFooter;
m.ShowHomePageLink = true;
%>
...
</asp:Content>
FROM BOOK: To reference public properties in a master page, we add the @MasterType declaration to the content page and reference the property using Master.<PropertyName>.
QUESTION: But what happens internally? Does all of the master's and content page's properties, function gets complied into one class? Or something else?
I have create a list of public properties in our custom page. However, when I want to assign the property on any aspx file, it does not show in intellisense and when I use it it said it is a invalid attribute of element "Page".So, 2 question.How do I make it such that it shows up in intellisense?Can I set any localize variable as a value of the property in the page directive?here is the property on my base page:
