Custom Controls in C# .NET

Embedding user controls in a Windows form is just like adding a simple button or text box that are already provided with .NET. These basic controls were written essentially like you code your own controls. Typically the controls you design are to be used in multiple forms or to modularize your code. These reasons help reduce the amount of code you have to type as well as make it easier for you to change your implementation. There should almost never be any reason to duplicate code because it leaves a lot of room for bugs. So, implementing functionality specific to your control in the control's source code is a good idea. This reduces code duplication as well as modularize your code, which is a good programming guideline.

UI Datepicker and web user controls



I have developed an application using the Master-Detail pattern described in this Matt Berseth article.

The only difference between Matt's article and me is that I am using a FormView object in place of a DetailsView.

Everything works fine except that the formview object, in my case it's inside a user control and I can't figure out how to use the jquery datepicker UI plugin.

I have tried to put the script block for the datepicker either in the aspx page as well as inside the user control but in both cases the calendar does not come up when the related textbox get the focus.

Any suggestion on how to work with the datepicker inside an ascx?

thanks in advance!

UI on the Fly: Use the .NET Framework to Generate and Execute Custom Controls at Run Time


Creating UI controls on the fly can be accomplished via run-time code generation. And there are lots of reasons to do so. Generating these controls once and then reusing them as needed is more efficient than generating the controls each time. Read on.

User Preferences: Manage User Settings in Your .NET App with a Custom Preferences API


There are plenty of options out there for managing user preferences including custom configuration files, the Windows registry, and the isolated storage. But each option has its pros and cons -- and a bad choice can make life difficult. In this article, the author evaluates various options and identifies the characteristics of a good preferences API. Based on those characteristics, he introduces an API that is specifically designed for preferences management, one that offers the best of all the options.

InfoPath: Turn User Input into XML with Custom Forms Using Office InfoPath 2003


Office InfoPath 2003 is a new Microsoft Office product that lets you design your own data collection forms that, when submitted, turn the user-entered data into XML for any XML-supporting process to use. With an InfoPath solution in place, you can convert all those commonly used paper forms into Microsoft Office-based forms and end the cycle of handwriting and reentering data into your systems. Today organizations are beginning to realize the value of the mountains of data they collect every day, how hard it is to access it, and are striving to mine it effectively. InfoPath will aid in the design of effective data collection systems. Here the author shows you how to get started.

Advanced Basics: Adding New Features with User Controls


In past versions of Visual Basic, there were rudimentary graphics controls. In Visual Basic .NET you have the GDI+ library, which enables you to draw lines, circles, and most anything else. But how can you use the functionality of GDI+ to create lines and other graphics that respond to user mouse clicks and events? Find out.

Windows Forms: Developing Compelling User Controls that Target Forms in the .NET Framework


In the beginning, writing controls meant dealing with Windows messages. Then came Visual Basic controls, which introduced methods, properties, and events. Later, ActiveX controls, which ran atop COM, became popular. While each innovation in control writing brought more flexibility, nothing has matched the versatility of the new .NET Windows Forms controls and Web Forms controls. This article, the first of a two-part series, introduces the reader to Windows Forms, beginning with their inheritance from one of the .NET CLR base classes, which makes control creation much faster than before. Control programming is illustrated through the development of a login control. The equally flexible Web Forms controls will be covered in Part 2.

How to add designing in Custom Controls ?


Hi ,

I am trying to create Custom control. I have created simple TextBox, Label, Buttons  etc. and added my own logic for their working,  but i want to add  some designing to that controls.I tried to add CSS file for that from the Add New Item, but there is no list for CSS. 

I added forcefully but it is not supporting CSS files.It seems that Custom controls does not support designing and layout through CSS.

Can you tell how can i polish my controls with beautiful designing and layouts ?

asynchronous loading user controls


I have 3 user controls that I have to load at the same time.  They each contain a gridview that pulls data from the database.  They are doing a "delay" load of the data so there is a progress bar template that shows that the data is loading however the first gridview fires and loads, then the second, then the third and I need them to all fire at the same time.  Any ideas? 

User Controls and Control Extenders


Two separate questions, but sufficiently intertwined that I'm going to try the two together....

Firstly - User Controls and Behaviours

I have a User Control which contains a few visual controls.  I am attaching some behaviours by using GetScriptDescriptors and am passing some JavaScript to the browser using GetScriptReferences.  That is all rock solid and working well.  However, when developing, I did discover that I couldn't attach the behaviours to the User Control itself - not surprising as rendering a User Control does not create a DOM element which represents the actual control.  So, I have attached my behaviours to a "random" TextBox within the User Control. 

So - first question, is there a better way to do that?  For example, should I always be rendering a SPAN as an element to surround the control?  Not sure what that would do to the robustness of the rendering.  What is the right way to attach a behaviour to a User Control.

Secondly - Accessing those same Behaviours later

Assume I have placed a User Control on the page.  That User Control exposes a Property (actually a Javascript Function of course) which does "something" to the control - for the sake of example we'll say that the function is set_Border(colour). 

Large document libraries with a custom user interface


We recently migrated our document management system to SharePoint (WSS 3.0) and I adapted my VB6 client application to search for and retrieve a list of documents from this new SharePoint library using the Lists web service. Although the total number of documents in this library is 90,000 at one site and over 145,000 at another, my VB6 application never retrieves more than 600-700 documents at a time. From reading white papers such as "Working with Large Lists in Office SharePoint Server 2007" (http://go.microsoft.com/fwlink/?LinkId=95450&clcid=0x409), it appears that if my custom user interface limits the number of items returned in a search of these large lists, that it may not be necessary to put these documents into folders. However, our current scanning software, KnowledgeLake Capture, by default places newly scanned documents into folders based on the year, month, day and hour, which means that these documents are placed in nested folders 4 levels deep.

There are also some 20 metadata fields on these document libraries that allow us to filter these document libraries so that search results will in most cases be limited to a few hundred items.

We acquired new servers (Windows Server 2008 with SQL Server 2008) to host our SharePoint libraries and we are running WSS 3.0 S
