Choosing Between a User Control or Web Part for SharePoint

Posted By: Amit Mehra     Posted Date: January 22, 2010    Points: 2   Category :SharePoint
SharePoint will only display Web Parts on a page. However, there are publicly available shims that allow you to write user controls and have them be displayed as a Web Part. From SharePoint's point of view, the shim is a Web Part. From the point of view of the user control, the shim is simply a control in .NET that is including the user control

Ajax, Smart Parts(web part w/ ajax support), User Control, and a GridView


So I am playing around with a user control that I created that adds some functionality to a SPList. I have scoured the web looking for a way to get a web part that had a gridview with custom buttons that is bound to certain Items in a sharepoint list. I found Smart Parts and created an Ajax enabled User Control. the problem is that the label is updating but the gridview is not. and on a site note how can I format the Time on Board column to not include milliseconds(the fields are showing up like '1.02:48:31.8633636') i just want 1.02:48 and maybe the 31:

here is my ascx:

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="AlertControlWebPart.ascx.cs"
  Inherits="AlertControlWebPart.AlertControlWebPart, AlertControlWebPart, Version=, Culture=neutral, PublicKeyToke

Get context to a control in web part from visual user control


I have a Visual Web Part (lets call it "ABCWebPart").

I'm attempting to create a connection to another web part which means I have to create the ConnectionProvider in the WebPart class (ABCWebPart.cs).

The value I want to set in my AJAX provider interface is a control I created in my visual user control (ABCWebPartUserControl.ascx).

How do I get the context of the TextBox control from my Visual user Control in order to assign it's value into the AJAX provider interface?


Thanks in advance,

Visual Web part with embedded User Control, fields are null


I have a legacy ASP.Net application that consisted of a series of ascx user controls which I am attempting to convert into visual web parts.  

I have wrapped each ascx in its own visual webpart and deployed to my site. Within my site I am able to add some of these to my pages and they render properly.

The ones that I am having difficulty with are those ascx user controls that have a child reference to other custom user controls.

For example I have CustomerinfoUserControl.ascx that has many fields within the control, but one is also a custom user control to select the date called DatePicker2UserControl.asx

Here is the declaration within CustomerInfoUserControl  and usage …



Deploying ASP.NET User Control into Sharepoint WebPart


The problem seems simple, but I cant figure out a way.

I have a asp.net user control "ucFetchDataWS.ascx" and want to deploy in one of the page in Sharepoint using a Web Part.
Is there any Out of the box webpart that can be used? IF not, what could be the custom approach?

Also if i want to pass some parameter into that UC, how is that possible?

Any help for the same?

SharePoint Application and Site Pages - Part 1 of 2

In this first part of the two part series, Steven covers the differences between Site and Application pages in SharePoint 2007, why each may be used in various circumstances, and prepares for the construction of a menu located application page. After a brief introduction he examines the concept of Site Pages and Application Pages separately in detail with supported screenshots.

SharePoint Application and Site Pages - Part 2 of 2

As the second article in a two part series, Steven examines the attributes and details of a SharePoint 2007 application page, including the construction and feature deployment of the same page based project. Since this is a WSS level objective, as opposed to MOSS, you will not need MOSS to work with the code included in this project. Windows Server 2003, WSS, and Visual Studio 2005 are all that is needed, with no additional add-ons. He provides a detailed analysis of each step involved in the creation and deployment of the project.

ASP.NET DropDownList Web Control, Part 1

Anybody with much experience in ASP has written an include file function for populating the contents of a SELECT dropdown list with entries from a database. Some of the more advanced users have even gone so far as to add caching to their function to reduce database hits for these rarely changing menu options. Naturally, these same techniques are going to be used with ASP.NET, but with a new programming object model. ASP.NET provides a web control, the DropDownList, which can be used for the same purposes as our custom built SELECT tag from Classic ASP.

Creating Sites/Lists/List Items under Current User Context in SharePoint By Using SPUserToken

Usually we do this by performing the action under RunWithElevatedPrivileges method and updating the listitem using SPListItem.SystemUpdate() method (see here). but this approach has its own flaws like (RunWithElevatedPrivileges will run under system account, we cannot use SystemUpdate for SPSite,SPWeb,SPList, since it runs under system we will "CreatedBy" by as SystemAccount).

How to track the changes of user contacts(colleagues) by using SharePoint API
