I am new to SharePoint development, I am using VS2010 and SharePoint2010.
I am wondering whether there is a restriction using a asp.net ListView in a SharePoint web part control. Because for some reason the intelliSense does not provide me ListView, just a GridView
Thanks
Web Parts in SharePoint are ASP.NET Web Parts. So you can freely use without any restrictions the ASP.NET Controls.
The Code Behind might use the SharePoint API but everything you can do is provided by ASP.NET.
Edit:
Are you missing an Reference for the ListView ? You need to add a reference to System.Web.Extensions in order to use the ListView
There is not such kind of restriction in SharePoint. You can use any kind of asp.net control in SharePoint.
For ListView intelliSense, you need to register system.web.extensions in your control or webpart before using ListView.
Please copy below code for register Library:
<%# Register Assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
Namespace="System.Web.UI.WebControls" TagPrefix="asp" %>

I have searched for days trying to find answers about how to configure AJAX Toolkit to work on my ASP.NET VB.NET site. I am having issues both with my development machine and on my hosing site. I cannot find a good reference on the settings for the web.config file, and the reference in my webpage that will allow the controls to work. Here is as much information that I have and I suspect most of it is wrong. If anyone is actually using AJAXToolkit that comes with Visual Studio 2015 and could provide some guidance I would greatly appreciate it. Here is the information I have.
My Configuration.
* Microsoft Visual Studio 2015 (64bit)
* Hosting with GoDaddy who says they support AJAX but does not say if that is AJAX TOOLKIT.
* ASP.NET AJAX Control Toolkit Version 1.0
* .NET FRAMEWORK 4.1.41102.0
* Development in ASP.NET VB.NET code behind pages.
* AJAX toolkit has been installed on my development workstation version 17.1.0.0
web.config file has not been modified to reference AJAXToolkit as I have not found a good example for this version of AJAXtoolkit.
I have added the following lines to my web.config file in the following areas.
<assemblies>
<add assembly="AjaxControlToolkit, Version=17.1.0.0, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e"/>
</assemblies>
<controls>
<add tagPrefix="ajaxToolkit" namespace="AjaxControlToolkit" assembly="AjaxControlToolkit, Version=17.1.0.0, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e"/>
</controls>
On my test page in the header section.
I am actually amazed at how confusing this is. It almost appears that Microsoft has abandoned or never actually adopted AJAX. One would think that simply dropping a component from the Tool Bar into your application should actually work. But I have discovered that is far from the truth.
I have ventured down many different paths to resolve a problem on my site and the AJAX Tools will resolve it if only I can get any one of them to work.
Your help again is greatly appreciated.

In all my pages I simply have this directive:
<%# Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="act" %> and have included AjaxControlToolkit in my project references
I have a "Data view web part" created from SharePoint Designer. I added the web part to my visual studio project as a "Web Part" . I want to know how to add the web part to an application page.
Hi i know its kind of late but, today i had to do the same thing, so i followed a great answer on sharepoint.stackexchange.com. But basically is like adding any other asp.net control on an APS.NET page.
First you need to define the prefix for that assembly
<%# Register tagprefix="prefix" namespace="NameSpaceOfTheWebPart" assembly="FullAssemblyName" %>
ex:
<%# Register tagprefix="csm" namespace="MySolution.VisualWebPart" assembly="MySolution Version=1.0.0.0, Culture=neutral, PublicKeyToken=335eef5f6f60e56b" %>
and then add the web part to the page (on the main place holder) using the required attributes by asp.net (ID and runat).
<prefix:WebPartClassName ID="ID" runat="server" />
The only thing is that you won't be able to edit the page and modify the Web Part through the browser, if you need to modify any other property of the Web Part you will have to do it from the html or code behind.
here is the url of the link i followed:
https://sharepoint.stackexchange.com/questions/26508/is-it-possible-to-add-web-parts-to-an-application-page
i hope it helps.
I am hoping someone can help me. I am trying to add Ajax controls to my VS 2010 project for the first time. I have previously gotten it to work when I used VS2008. I keep getting this exception:
Error 56 The type 'System.Web.UI.ExtenderControl' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.
Here’s what I did. I downloaded the ajax 4 toolkit and added a reference to the project. I also added a reference to system.web extension to my project. When I do this these lines get added to my web.config
<assemblies>
<add assembly="System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/></assemblies></compilation>
I added these lines to my aspx file.
<%# Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="cc1" %>
And
<cc1:CalendarExtender runat="server" Id="txtDateOfBirth_CalendarExtender" TargetControlID="txtDateOfBirth"></cc1:CalendarExtender>
Etc.
I also backed off and tried ajax 3.5, this didn’t help. I did notice that the ajax dll is 4.1 while the 'System.Web.Extensions is 4.0. I don’t know if this matters but I cannot find ajax 4.0 or 'System.Web.Extensions 4.1.
Thank once again in advance.
This is not a solution but a recommendation: stay away from the Ajax toolkit or you are asking for trouble; use jquery instead (seriously, I have been down this road).
I have a classlibrary. This library contains widget.ascx control. How to load this webusercontrol from web. I know "LoadControl". But this not applicable.
How can i load web usercontrol from library?
2009.09.24
My main goal is i'm creating addon based web application. Every addon will be widget of web application.
I need dynamically load web usercontrol from library
You need to add a reference of the library to your web project.
Then instantiate it as you would with any other control, either programatically or in an #Register directive.
Kindness,
Dan
In addition to obviously adding the DLL to your project references, you also need to register the control. You can do this on each page that will use the control, but I usually prefer to do it in web.config. As a quick example, here's the line I used to register the Infragistics UltraWebGrid control in my app.
<pages>
<controls>
<add tagPrefix="ig" namespace="Infragistics.WebUI.UltraWebGrid" assembly="Infragistics35.WebUI.UltraWebGrid.v8.2, Version=8.2.20082.1000, Culture=neutral, PublicKeyToken=7DD5C3163F2CD0CB"/>
</controls>
</pages>
TagPrefix works kind of like an in-page namespace, so if I had a bunch of controls I was importing from one DLL, they'd probably all have the same TagPrefix. In the page, I'd simply reference my control as follows:
<ig:UltraWebGrid runat="server" SetSomeOtherPropertiesToo="blah" />
I am not sure how the .ascx file is added to your class library. Normally user controls are loaded using LoadControl which requires an existing file. In case the user control is compiled as embedded resource in your class library you could use GetManifestResourceStream() to read the user controls' contents and then ParseControl to create a control from the string read using GetManifestResourceStream.
I tried to bring a previously done webform made in vb.net to an IronPython asp.net website with no luck. After seeing it didnt work, I tried to write the simplest codebehind vb.net webform to see if there was a problem with vb.net in an IronPython website and I got the following usual error
"be sure that the defined class in this file matchs with the one in the attribute inherits and that it extends the right base page (page or control)" (sorry if the translation isnt the most accurate I get that message in spanish)
but if I create a vb.net webform in the same website, with the sourcecode in the same file (with the vb.net code between script runat="server" tags in the same page) I get no problem.
Do I have to configure something for both kind of sourcecode languages to run in such way in the same IronPython website, like configuring something in the webconfig file or is there some compatibility issue for doing that which can't be resolved?
The code between <script /> tags is compiled dynamically when the page is first run. This enables you to mix languages. However, the classes in your code-behind files are statically compiled into an assembly by VS.NET ... and a VS.NET project can only support one language at a time.
One solution is to put your VB.NET code-behinds in a separate assembly. For example:
Add a new VB Class Library project to your existing solution
Add a reference to System.Web
Create your VB.NET code-behinds. They should be normal classes inheriting from System.Web.UI.Page.
In your ASP.NET website project, add a reference to the new project
Edit the # Page directives in your *.aspx files to inherit the classes in the new project
e.g. <%# Page Inherits="YourNewVBClassLibraryProject.MyVBCodeBehinds" ... /> where the Inherits attribute contains the relevant namespace-qualified class name
Thanks for the reply Serilla. Your information was interesting but I simply solved it by creating the app_folder and adding the vb files there. Do you think I could have some future problem for doing so?
The problem with the vb files was when these lines in the web.config were enabled for Ironpython to work
<pages compilationMode="Auto" pageParserFilterType="Microsoft.Web.Scripting.UI.NoCompileCodePageParserFilter" pageBaseType="Microsoft.Web.Scripting.UI.ScriptPage" userControlBaseType="Microsoft.Web.Scripting.UI.ScriptUserControl">
<controls>
<add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
</controls>
</pages>
when I removed them, vb code behind files worked but ironpython didnt. When the lines were there, Ironpython code behind files worked but vb ones didnt
