understand what is going on in the code line below:
Table t = (Table)Page.FindControl("Panel1").FindControl("tbl");
I understand Page.FindControl("Panel1").FindControl("tbl");
Why is there a (Table) before the Page.FindControl?

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>
For example, i am using forms authentication... and i notice there is a system.web and then it closed /system.web and then below configuration there are additional location tags.here is an example, if you ntoice there is an authentication mode=forms with authorization i presume this is the ROOT....... It is also self contained within a system.web .... Below this there are more location= with system.web tags....I have never really understand what i am actually doing.. I have tried checkign the MSDN documentation but still i don't fully understand up....
If you notice with my example.... everything is stored in 1 web.config... i thought the standard waas create a standard web.config and then create another web.config in the directory where i wish to protect it..???
<configuration>
<system.web>
<compilation debug="true" strict="false" explicit="true" targetFramework="4.0" />[code]....

I am working on a project for my company, and while tracing previously written code I came upon this:
<value>A payment authorization for {0:C} has been received.</value>
What does {0:C} mean? I have been trying to find out and am having no luck.
Special symbols are a real pain to learn about because you can't Google for them (try doing a Google search for "<%#" and you's get nothing).
I've been a programmer for many years, and I'm trying to get my head around ASP.net, and especially the "special symbols"; what they mean, where to find out more information about them. Because they're impossible to search for, it'd be wonderful if there were special resources in place to help newbies learn about these.
Specifically, I'm looking for detailed instructions on the porpose for, and use, of the following constructs:
<%@ %>
<%$ %>
<%# %>
<%= %>
What is expected in each, what is allowable in each, and what "gotchas" would a newbie have to be careful for when employing each.
For example, I want to do some coding in a <%# %> block, like:
Text="<%# if (Eval("InUse")) {Eval("ProductName")} else {"Not In Use"} %>"
-- would this be allowable, and if not, what are reasonable alternatives?
your posts and answers are very informative and helpful in my own devolopment and understanding the nature of the beast. Im running vs2010 on a 64bit windows 7 devolopment machine. For days I have been trying to get a Microsoft Reportview to render in a popup. ( i have done this in vs2008 ). I have tried applying the same code from vs2008 to Vs2010, but am comming up with page erros. When loading the default.aspx ( testpage ) I get 'Done but with errors'. If I click on button 1 which shows the popup, I get the report viewer, but it just sits there 'loading'. From advice givenm on this forum, I have used the IE view source code to try and loacate the problem... but to be honest, I dont understand why the page complies ok, but i get errors when it is run, or indeed how to rectify the problem. I have highlighted the two errors.Ie view source code:

I am new to ASP.NET MVC 2 and I am having a very hard time figuring out how to do even the most simple things. I have a couple of books on ASP.NET MVC as reference but I cannot find any answer to my question. Here is what I basicalyl have and need:
I am trying to create a page that shows me a table that contains some Product Statistics with columns such as Date, ProductCount, PriceCount. On the same page I want to add some filters such as "Product category" (dropdown) and a date from and date to (jquery ui datepicker). When a user clicks on "Filter" it should reload the page and in the Product Statistics it should show the statistics filtered by "Product Category" and the date range. At the same time I want to make sure that the selected Product Category from the dropdown list does not get lost, the same for the date pickers.
I have a GlobalReportController with two actions: "Index" and "Filter". I have also a GlobalReportIndexViewModel and a ReportFilter. In the "Index" action, I retrieve the complete list of statistics and product categories and fill up the ProductStatisticsIndexViewModel.
I am having a whole lot of problems trying to grasp how the ASP.NET MVC paradigm works exactly.
I'm trying to build up some regular expressions to validate some textbox controls. I have done some research and testing but cannot get this one working. Examples of what i am trying to create regular expressions for are as follows:
Range 0-45, 0 decimal places
Range 0-20, 2 decimal places
Range 16-65, 0 decimal places
Range 0-99, 2 decimal places
Range 0-1500000, 0 decimal places
Range 0-200, 1 decimal place
For 1 and 5 respectively, I have used
([0-9]|[0-9]d|45)$
([0-9]|[0-9]d|1500000)$
The first one I am having problems for is an age range of 16-65 (inclusive), where I want no decimal places. After a post on here (Regular expression to allow numbers between -90.0 and +90.0) I thought I could use the logic and get it sussed, but can't! The expression I got to was:
(d|([1-6][6-4]))|65
I am building a medium to large application with ASP.NET MVC 1.0 (we'll upgrade to the latest after we meet some schedule commitments). The application contains a number of workflows, with a separate controller for each workflow, and the home controller owning the main page of the application. So, I end up with the home page, on which the user makes selections and then clicks one of a number of action buttons to proceed down a given workflow. For a given workflow, I seem to have the following flow between controllers:
homeController (home view) --> action-button --> workflowController --> homeController (completion view)
I figure the action-button does a post to the home controller, which the selections the user made are saved to session state in the appropriate model. The workflowController will handle things as the user moves through one or more views specific to the workflow, but then things end on a common completion page.My question(s):1 - Is this a reasonable way to break up responsibilities amoung multiple controllers?2 - How do I actual accomplish the hand-off to the workflow specific controller? I'd really like to avoid a redirect and the attendent round trip to the browser since controller structure is really an internal implementation issue and shouldn't impose a performance penalty on the user.3 - Is it possible to pass a model from the originating controller to the destination controller, or do I have to exclusively depend on persistent state to pass things to the "next" controller?
If I create a new project, start this project and look at the source code, I see that there are some additions to the original code. The first this, what is "ViewState" and what does the hash mean? Why is the input control hidden?Here an example:
[code]....
I have an ajax form that has a simple click event. Inside the click event, at the end of the method, I have a Response.Redirect back to the same page. For the purpose of this thread, I will leave out the reasoning of this (it is just something that I had to do). Once the ajax call is complete and the redirect takes place, all of my default control viewstates get wiped out. The thing that doesn't make sense, is that if I define my own ViewState right before the Response.Redirect, these ViewStates also get wipedout. So, my question is, do ViewStates only hold their values after one postback/refresh? And, is there a way to use ViewState with the method described above? I am being forced to use the querystring to pass parameters.

I have a web site that uses the App_Code folder. There are several CS files and classes in that folder. All of this works fine up to this point. However, I wrote an extension method with its own class and file. This fails with the following ambigous reference error (the app is in C#):
Compiler Error Message: CS0121: The call is ambiguous between the following methods or properties: 'GSGeneral.ExtensionMethods.IsNumeric(string)' and ''GSGeneral.ExtensionMethods.IsNumeric(string)'
If I change the extension to a plain static class, there are no problems with it. Based on that, it seems like this is related to it being an extension method.Now I know a work around is to move the file out of the App_Code folder - I've tried it and it works. My question is why does this have issues when all of the other items in the App_Code folder do not.
Asp.net 3.5 using code behind I am using a repeater control. My datasource appears in code behind. I decided to NOT have my listitems populate from the database. I want the user to select a value, send it to the database via an update statement, and then when the user returns to the page (on pageload), have the user's previous selections appear on the screen. note the following:
When I use textboxes and labels, ALL of my data appears within the table of the repeater control. However, when I replaced one of the text boxes (originally used for testing purposes only) with a dropdownlist, I get the following error message'ddlDDuring' has a SelectedValue which is invalid because it does not exist in the list of items.Parameter name: value My Repeater1_ItemCommandI updates the data within the repeater perfectly. On page load, I want the data from the database to display as the dropdownlist's selected value (or selected item.text). Here is my Asp code
<asp:Repeater ID="Repeater1" runat="server"
onitemcommand="Repeater1_ItemCommand">
---
<
td><asp:Dropdownlist ID="ddlDDuring" runat=server SelectedValue ='<%#Bind("DueDuring")%>' >
<asp:ListItem Value="-select-" Text="-select-" />
<asp:ListItem Value="1st half" Text="1st half" />
<asp:ListItem Value="2nd half" Text="2nd half" />
<asp:ListItem Value="Split" Text="Split" />
</asp:Dropdownlist> </td>

I tried the following code changes on asp page: I changed "SelectedValue" to "Text" and still get the same error message I changed "SelectedValue" to "SelectedItem" and don't get the error message, but dropdown is not populated I set AppendDataBoundItems = true Set first list item value = "" Verified that every field in the table column matched the items in the dropdown list. There were NO null fields in the database.
I just want to understand this error message, as I have exhausted all that I am doing. I also made an attempt to bind the dropdown list, but sine this can only be done within the loop of finding the repeater control, I would either get an error message, or it just would not work.
It was doing exactly what I expected until I added more than 1 property to it. It seems if I set the value of a property this, in turn, sets every property in the handler to the same value.
I figured it had something to do with the "shared" but if it's not shared then I would have to declare an instance on my page which would kinda ruin the state of my variables (otherwise, I'd just put them all in my class), right??
[Code]....
public class OneControl
{
...
public OneControl Content(Action value) {
ContentProperty = value;
return this;
}
public void Render()
{
ContentProperty();
}
...
}
Then I got this in my view :
<div id="pleaseHelpMe">
<% OneControlInstance.Content(() => { %>
Some Mixed Stuff <%= Example%> Euros
<% }).Render() %>
</div>
I would like to use this syntax in my UI library, I know how to implement this but I don't know HOW it actually works! I understand that somewhere and somewhat a delegate is created and provided as an argument of the method Content, but can't find any information about this mecanism or technic. Assumed current correct answer : The compiler translates the aspx code below into (symbolic translation for comprehension):
<div id="pleaseHelpMe">
<% OneControlInstance.Content(() => {
ViewPageInstance.Response.Write("Some Mixed Stuff ");
ViewPageInstance.Response.Write(Example);
ViewPageInstance.Response.Write(" Euros");
}).Render() %>
</div>
I am working with a sql server database with about 50 stored procedures. The database and stored procedureswere not created by me. The stored procedures all begin with a number in their name.
Example: 17P_Comsetter
The problem I am having is that if I try and execute the stored procedure at the command line in Query Analyzer,the query analyzer appears not to like that the stored procedure begins with a number. For example:
If I try an run the stored procedure as follows:
EXEC 17P_Comsetter
Then I get the following error message:
