There are some syntax errors that are shown on IE8, on the error window, it shows line : 'some number' , code : 0 , char : 1 when I go to that Line via "View Source" I see nothing wrong there. it might be that error exists on the other place. How can I find the right error place?
View 5 RepliesOn my site I put things in Web user controls. For example, I will have a NewsItem Control, an Article Control, a ContactForm control.These will appear in various places on my site.
What I'm looking for is a way for these controls to pass messages up to the Page that they exist on.
I don't want to tightly couple them, so I think I will have to do this with Events/Delegates. I'm a little unclear as to how I would implement this, though.
A couple of examples:
1: A contact form is submitted. After it's submitted, instead of replacing itself with a "Your mail has been sent" which limits the placement of that message, I'd like to just notify the page that the control is on with a Status message and perhaps a suggested behaviour. So, a message would include the text to render as well as an enum like DisplayAs.Popup or DisplayAs.Success
2: An Article Control queries the database for an Article object. Database returns an Exception. Custom Exception is passed to the page along with the DisplayAs.Error enum. The page handles this error and displays it wherever the errors go.
I'm trying to accomplish something similar to the ValidationSummary Control, except that I want the page to be able to display the messages as the enum feels fit.
Again, I don't want to tightly bind or rely a control existing on the Page. I want the controls to raise these events, but the page can ignore them if it wants.I'd love a code sample just to get me started.
I know this is a more involved question, so I'll wait longer before voting/choosing the answers.

View 2 RepliesI am developing a web application in which I am suddenly facing an issue. I have a webpage which contains many controls, one of the control is JQuery color picker. Now, I am upgrading my system with telerik controls. As part of this process, I replaced textbox(txtcolor) with radcolorpicker with a different id(colorPicker). Suddenly, my code behind file is not throwing any errors like 'unable to find txtColor'. It is running successfully without build errors. But, when I open the page, system is throwing runtime exception(txtColor not found) which is correct.
I tried to change other controls with asp.net controls, still the problem persists. So, I dont think it is anything to do with telerik.

The following CLR syntax works fine in my aspx page:
<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="Website.MyBasePage`1[HomePageViewModel]" %>
But this C# syntax does not:
<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="Website.MyBasePage<HomePageViewModel>" %>
Note, I am not using ASP.NET MVC, but this works fine if using System.Web.Mvc.ViewPage<> from ASP.NET MVC.
My MyBasePage looks like this:
public class MyBasePage<TModel> : Page where TModel : class {
public TModel Model
{
get { return (TModel)HttpContext.Current.Items["model"]; }
}
}

For reporting we used report RDLCs and displayed using an ASPX form. We implemented using the route as shown below. This resulted in forcing us to use the page route below and also to use the hyperlink instead of the normal Action Link. The question is how do we convert the asp:hyperlink ASPX syntax to Razor syntax.
//Custom route for reports routes.MapPageRoute( "ReportRoute", // Route name "Reports/{reportname}", // URL "~/Reports/{reportname}.aspx" // File );
<li><asp:HyperLink ID="hypReport" runat="server" NavigateUrl="<%$RouteUrl:routename=ReportRoute,reportname=StaffRpt%>">Staff Report</asp:HyperLink></li>
With the following code I create a combobox in a panel which is in the pane of an accordion panel.

Now when I click on the arrow of the combobox, the list is show somewhere else on the page and not where it should be.
It seems the list is not positioned relative to the textbox.
I want to place two datalist controls at the same (x,y) position. When the first is visible, second should be invisible.
How would I go about implementing this?
