Could someone give me a small example how i can make reusable WebUserControl (.ascx) file.Basically i need to make a employee lookup utility where users enters employee id to get Emplyee information.Once the Emplyee information is available, it is used in various data entry tasks by the page that includes the control.
View 1 RepliesIn ASP.NET web forms we created few user controls (.ascx) which were used in almost all of the projects. I'm not sure how to achieve same in the MVC?
View 2 RepliesI'm trying to create reusable "zones" but am having trouble figuring out how to give them all unique ids.What I'd like is to be able to create a component which can be put on an mvc page using the usercontrol syntax or using RenderAction or RenderPartial. I want to be able to update these components' content using ajax, so I need someway to reference them by id. However, there is no mechanism in MVC that wraps anything in a div or something like that.
I've learned that if I extend ViewUserControl and put the controls on the page like so:
[Code]....
This way, I can pass the previous ID and put it in ViewData, in case I need it laterThen, I can even go through all my controls on page load event in the master page and get my unique ID and write somekind of register javascript function to the page so that I can do javascript stuff if I want when the page loads.
[Code]....
Is there a more elegant way to do this? I see similar stuff from 'Areas' but never seen an example where someone has put more than one area on a page and then needed to reference them via javascript. This also seems similar to custom templates, but I'm having trouble figuring out how that would work.
I want have a web application that I am putting together - but I have started to see that some of the things I am writing are repeated over and over, example -
GetDepartments() in the code behind has all the database connections and is linked to a stored procedure.All it does is return Department Names' and Ids', ie then bind them to a dropdownlist.My question is this I have seen Class files - I want to know if I can put this type of information in there and just call it whereever I need it in the site and then bind to whichever dropdownlist I need to?I have had a look around the net and even saw some examples by scott mitchell - but it used datasets (.xsd) files etc and dont want to be using them, plus it was a little over my head. Does anyone know of some good simple examples out there that I can follow, or maybe some examples on here?
I have a situation where I need to maintain a large number of related integer values in my ASP.Net 3.5 application. The SortedList seems perfect for this purpose. If this were a Windows app I'd just create a class and setup one method to Set values within the SortedList and another one to Get values out of it.
But being a web app, I'm not entirely sure of the best approach to use. Sure, I could just create one method for Set and another for Get but that doesn't seem very "clean".I thought about creating a UserControl without any visual elements but am not sure if that makes sense.How would you go about implementing such a SortedList in your web app?
I have been given the task to create a TAB control ( probably the Jquery tab control) as the company wants the Lazy loading of data.
The tab control should not have fixed items on it. It should be reusable in different projects . So I cannot fix the items in the tab control. Depending upon the project the tabs can change.
Need some great ideas on how I can achieve it.
Note: I am using MVC, VS 2008, C# for my development.
I am trying to write a simple library for MVC2 projects that takes care of user login, e-mail validation, password recovery, logging, etc. Since some of these steps involve user interaction, I need to have Views and Controllers in that project.In MVC2 Preview 2, one could do this by abusing areas (at least, it seems) since they were implemented as different projects. However, in the RC, creating a new area will merely create a subfolder. Since I want to share the base code between applications, that is not an option.I tried to brutally hack the AfterBuild steps into my project files, but that feels like the craziest hack ever.
View 10 RepliesI want to build a reusable library of User Controls.
I found this article:
[URL]
While it works for me, but I find it a bit cumbersome to implement, expecially for future maintenance.Also, I noticed that if you create the User Control with code in separate file, it will not work. In this case, you will not get any error, but, the page where the control in registerted will not show (you will get blank page).Why I am getting BLANK result when I develop the User Control with code in separate file ?I appreciate your recommendation on the best approach to implement a library of Reusable User Controls. Also, I did not like the method of Web Controls, becuase they are difficult to implement.
I want to build a reusable control which will enable e to perform add/edit/delete operations easily. All I want to do is give the control a datasource and it will handle the rest.
What controls should I use? I want it to be as user friendly as possible.
In .NET land what would be a good approach for quick prototyping of a concept (i.e. development just on my PC) that could then be extended out to product (users across LAN/WAN), BUT in a fashion that the model/business logic code and data access layer code can be used as is? One thought for example I had as to do:
(a) WinForms with business logic and Entity Framework layer to SQL Server Express on my PC, then
(b) Go then to ASP.net (using the business logic / data library) with SQL Server/IIS
Say you have a for loop which renders a bunch of the exact same control. This is probably done with RenderAction or RenderPartial.
What is a way to ensure that each of these controls in the list gets wrapped in a div with a unique ID?
I need to have a section in my website dedicated to viewing and printing reports.I've created a Reports Table (ReportID, ReportTitle, ReportDescription, ReportCategoryID), so I can display a list of Reports on a page.I also have a ReportCategory Table (ReportCategoryID, CategaoryName, Active).So i could have all the categories in a dropdown perhaps(not sure it's the best option)
Then once a selection is made I can display the reports under that category.Clicking on any of them will then display the report or save it to disk.My question is, should I create a Reports Class? if so, can I get a few pointers
I have implemented AJAX for calling server side function using client side function call i.e Calling server side function using javascript tag by using PageMethod in javascript.
I have few question regarding the same implementation.

I'm working to move my simple asp.net website to a three layer architecture. Currently I have Linq queries like the one below in my code-behind files. Basically this code snippet retrieves a collection of customer data from the database and then binds it to a grid control.
I'm wondering if someone can guide me on how to rewrite this in order to move it to my newly-created data access layer. I'm thinking I will turn it into a class (e.g. GetUserBoxesByStatus()) that can be reused throughout the site.
var boxes = from p in sbm.Packages
where p.UserID == CurrentUserId && p.StatusID > 1 && p.StatusID < 3
select new { p.PackageTag, p.PackageName, p.DateReceived, p.DateShipped }; [code]....
Some of the options that I've investigated but have not had success implementing are the following:
DataTable --- returning a DataTable seems like the best solution but it also appears to require a lot of potentially unecessarry code to define a table (isn't the data source already mapped in my Linq 2 Entities dbml?)
IEneuerable --- I think I could pass an IEnumerable list between the layers but after reading many tutorials about Linq I'm still a little lost DTO --- Conceptually I think I understand what a DTO is but I am not clear on how to begin implementing this approach POCO --- Again, the concept seems logical enough but I don't know how to put this into practice
how they would tackle this using one of the above or some other solution.
I want to build my navigation so I can use it on multiple views. How do I do this? Nested views? Whats the best practice and show me a quick example?
View 1 RepliesI want to create a reusable user control which contains a date time picker in asp.net.

Also want to know, How to add this component in to the toolbox?
View 2 RepliesIn the project I have some custom WebUserControls for form elements (they encapsulate some standard validators and other system specific functions). My user controls are "DropDownListField" and "TextBoxField". In the code behind of a page I have this code:
string parameterValue = null;
foreach (object control in myMultiView.Views[myMultiView.ActiveViewIndex].Controls)
{
if (control.GetType() == typeof(DropDownListField))
parameterValue = ((DropDownListField)control).Value;
if (control.GetType() == typeof(TextBoxField))
parameterValue = ((TextBoxField)control).Value;
}
For some reason the "if" statements always return false even when I step through the code and see that "control" is getting assigned my web user control. This code is in another place in the project exactly the same except in the other location the standard .net controls "TextBox" and "DropDownList" are used and in the other location the code works. why this wouldn't work with web user controls?
UPDATE: Hmm so in debugging I found this:
?control.GetType();
BaseType: {Name = "DropDownListField" FullName = "WebUI.UserControls.Fields.DropDownListField"}
?typeof(DropDownListField);
BaseType: {Name = "UserControl" FullName = "System.Web.UI.UserControl"}
So typeof is just recognizing they are user controls not the full type it seems. how I would check for a specific user control type?
I want to add a webusercontol which contains a textbox and a label to the gridview control. I am binding a gridview with a datatable dynamically.
Here is my code:
@ Register Src="CompareBox.ascx" TagName="CompareBox" TagPrefix="objCompareBox" %><br>
<asp:GridView ID="grdfoneBoxContainer" runat="server">
<Columns><br>
<asp:TemplateField HeaderText="User control"> <br>
<ItemTemplate><br>
<objCompareBox:CompareBox ID="CompareBoxCol1" runat="server"/><br>.......
txt & lbl are two properties that are declared in WebUserControl but it's giving object reference error .

I put debugger into LinkButton1_Click event of user control but it never goes there.
I had this problem: I created a WebUserControl that used som Ajax stuff - hence it needed a ScriptManager.
The problem was that I couldn't add it to the WebUserControls html code (the .ascx file) since the WebUserControl sometimes was placed into a parent page that already had a ScriptManager, and I couldn't add a ScriptManagerProxy since the parent page sometimes didn't had a ScriptManager.
Alot of people just use a ScriptManager on the MasterPage, but this fails if: one doesn't use a MasterPage or one uses iFrames etc. that uses stand alone aspx pages, like Thickbox might do...
Here's the solution:
in the WebUserControls code behind (.cs file), put this:
protected override void OnInit(EventArgs e)
i was made 'webusercontrol'
and i use this:
event 'msgok' :when btnOk clicked
event ''msgcancel' : when btnCnl clicked
sub 'show' : show this dailog
problem : when i add my 'webusercontrol' to a page,
i can add events(msgok,msgcancel) to page codebehind,
but i cant add this to updatepanel tiggers.
make update panel able to add my 'webusercontrol' events ??
