Web Forms :: Create User Control Class That Extend Panel?

Aug 31, 2010

I'm trying to create a user control class that extends Panel. Essentially, what I want to do is to have a panel that fires off an event whenever it's clicked upon.

So, I create something like this:

[Code]....

And then, in the ClickPanel.ascx.cs file:

[Code]....

I'm not exactly sure whether this would work as I haven't had the opportunity to test it yet.

The problem is that I can't have a class inherit from Panel. Creating a user control class requires that my class extend User Control - at least that's what the error messages have been saying up until now. The problem is that if I do extend it from the base class of UserControl then I lose all the functionality of the Panel itself and the entire thing is rendered pointless.

Get The Functionality Of Namespaces Inside A Class?

May 1, 2010

I have the following code:

[Code]....

I would like the functionality of namespaces inside of a class, as in something that would let me call Step2.Execute() instead of having to put Step2_ in front of a whole bunch of functions. I don't want to have to create separate classes / modules for step1, step2, etc.

Is there a way that I can accomplish namespace functionality from inside a class?

Asp.net - Moving Functionality To A Class Library Project ?

Mar 30, 2011

I have a .net project whose part of the functionality is xls transformation. I now want to move that functionality away from the main project to a separate class library project.

I have no problems moving classes and accessing them, but part of the resources that I wanted to move were xslt files that define the transformations. Those files were originally located in the special asp.net folder: App_Data and then accessed using Server.MapPath(~/App_Data/XSLT/anXsltFile.xslt)

I wanted to move those files to that separate library as well, but not sure how to approach it, and how to access those files within the class library.

Forms Data Controls :: Create List View To Provide Functionality

Apr 26, 2010

I am trying to create a list view to provide functionality similiar to the pages in this article(will end up being much simpler in my case)

[URL]

Basically I need three columns. Column 1 will be populated on page load with a list of user names and some data. Clicking on a user from column 1 will query for data regarding that user and bring back multiple rows to be displayed in Column 2. Clicking on data from a row in column 2 will return rows to be displayed in column 3. I am just curious as to how some of you guys would approach this. Ive looked at grouping templates and some articles regarding listviews with multiple rows but. Would it be easier to use 3 seperate listviews? Any ideas or articles to point me in the right direction?

Trying To Re-create The Functionality Seen On 43things.com?

Aug 10, 2010

I am trying to re-create the functionality seen on 43things.com, where you enter a text and it gets added to the list below and also brings up "123 people want to do this". This entry seems to be permanently stored when you are visiting the site from your machine. I am just wondering how this works? Is it just a cookie placed on the user's machine? I also wanted to know how I could do the text addition in Ajax rather than having to postback? For ex. I just want an entry to be made and the "xxx want to do this" displayed as soon as the text has been submitted, like how it works with Facebook comments. Is there a component in AJAX control toolkit for ASP.net for this - I couldn't seem to find one?

C# - What's Functionality And Methods To Add "BasePage" Class

Apr 4, 2011

What cool functionality and methods do you add to your ASP.net BasePage : System.Web.UI.Page classes? Here's something I use for authentication, and I'd like to hear your opinions on this:

protected override void OnPreInit(EventArgs e)
{
base.OnPreInit(e);
// Authentication code omitted... Essentially same as below.
if (_RequiresAuthentication && !(IsAuthorized))
{
RespondForbidden("You do not have permissions to view this page.", UnauthorizedRedirect);
return;
}
}
// This function is overridden in each page subclass and fitted to each page's
// own authorization requirements.
// This also allows cascading authorization checks,
// e.g: User has permission to view page? No - base.IsAuthorized - Is user an admin?
protected virtual bool IsAuthorized
{
get { return true; }
}

My BasePage class contains an instance of this class:

public class StatusCodeResponse {
public StatusCodeResponse(HttpContext context) {
this._context = context;
}
/// <summary>
/// Responds with a specified status code, and if specified - transfers to a page.
/// </summary>
private void RespondStatusCode(HttpContext context, System.Net.HttpStatusCode status, string message, string transfer)
{
if (string.IsNullOrEmpty(transfer))
{
throw new HttpException((int)status, message);
}
context.Response.StatusCode = (int)status;
context.Response.StatusDescription = message;
context.Server.Transfer(transfer);
}
public void RespondForbidden(string message, string transfer)
{
RespondStatusCode(this._context, System.Net.HttpStatusCode.Forbidden, message, transfer);
}
// And a few more like these...
}

As a side note, this could be accomplished using extension methods for the HttpResponse object. And another method I find quite handy for parsing querystring int arguments:

public bool ParseId(string field, out int result)
{
return (int.TryParse(Request.QueryString[field], out result) && result > 0);
}

Forms Data Controls :: Caching DataTable - Create/cache Multiple DataTables?

Jul 23, 2010

Among the many aspects of asp.net that I haven't focused my development on yet is caching. I have a perfect application for it now, I think, with a GridView that sits inside a repeater, and is bound in the Repeater ItemDataBound event. The contents of the GridView will remain static for each Repeater data item for each Client. The nature of the data in the GridView is that it can change from day to day per Client, but wouldn't need to be refreshed more frequently than that. The Page istelf only deals with one at a time Client based on a QueryStringParameter. My questions are a) how do I cache the DataTable so that a call to the DataBase isn't made each time Repeater item is bound and b) can I create/cache multiple DataTables (one for each Client) and let them live for day, checking for existence before calling the SQL stored procedure to regenerate the data?

Web Forms :: How To Create Css Class At Runtime

I am unable to use the traditional method of doing so as one of the attributes need to be loaded at runtime.

As I am using the Coolite Toolkit, whenever i need to use a custom image onto one of the controls, the custom image path needs to be loaded in via a stylesheet class.
