SharePoitn Custom ListDefinition Validate Tag

Posted By:      Posted Date: October 27, 2010    Points: 0   Category :SharePoint


I am creating a custom calendar ListDefinition in SharePoint 2010.  I have the usual two calendar fields that comes as default which are



What I noticed is that the default calendar contains an inbuilt validation so that when the user enters an EndDate greater than the EventDate you get an error.

My questions on this are

1. How do I get this same logic into my custom schema.xml file.  I tried looking at the manifst.xml file after saving the list (default calendar instance) as a template but still could not find a logic.

2. I tried to introduce the following under the <MetaData> tag in the schema.xml

<Validation Message="Start Time has to be greater than End Time.">=EventDate&lt;=EndDate</Validation>

Still this did not work.

Any ideas anyone?

Custom Form with Lookup Field does not validate when it's set to require.


I have a lookup field in my custom new form and it's suppose to pull an id.  However, I have nothing to relate to this, so shouldn't the required validation trigger?

Is there a workaround for this or do I need to take this a step forward and write some custom code?


Thanks in advance!


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.

Writing custom MembershipProvider

ASP.NET Membership mechanism allows to use the build-in server tables to store and retrieve user data. By default, this mechanism can only be used with SQL Server database to which Microsoft provides suitable MembershipProvider class.
Inheriting from this abstract class, developer can use his own table(-es) from any database and use any database engine other than SQL Server, like Oracle, DB2 etc.

Custom Editing Behavior for DataGridView TextBox Columns

For various reasons I'm using a DataGridView instead of a ListView, and while configuring the DataGridView to look like a ListView wasn't much of a problem, there's one thing that got on my nerves, which is the behavior of textbox cells in edit mode: It is much too easy to leave the edit mode accidentally, simply by pressing the cursor keys at the wrong time. For example when the text caret is positioned behind the last character of the textbox cell content, and you press the right arrow key

Write Custom WebParts for SharePoint 2007

The popularity of SharePoint Portal Server 2003 led Microsoft to tightly integrate the next SharePoint version, Microsoft Office SharePoint Server (MOSS) 2007, with its ASP.NET 2.0 WebPart framework. This tight integration enables the ASP.NET and SharePoint developer to do a number of things that previously weren't possible

JQuery Validate plugin to validate a ASP.NET Form

The first time I used the JQuery Validate plugin, it did not work at all, see JQuery Validate odd behaviour with the ASP.NET Script Manager for reason, but perseverance and stubbornness prevailed and I finally created my first JQuery validated ASP.NET Forms contact form.

Writing Custom Web Parts for SharePoint 2007

As I mentioned in an earlier blog post, SharePoint 2007 is built on top of ASP.NET 2.0, which means you can now use ASP.NET 2.0 features (Forms Authentication, Master Pages, Membership, Site Navigation, New Data Controls, etc) when building SharePoint sites. This is true for both the new Windows SharePoint Services 3.0 version (which will be a free download) as well as Microsoft Office SharePoint Server 2007 (which costs money).

How to implement custom HttpContext for each request under class that implements IHTTPHandler


Hello All,

I created an application and implemented IHTTPHandler for all incoming request ending with ".aspx" extension.

Under "ProcessRequest" module, I am creating an instance of HttpContext (with URL attributes different from my application's URL i.e. if I am working on localhost then speciying Yahoo.com as its URL) and assigning it to "context" which comes as method argument.

After redirection, an error is generated. Also, the custom HTTPContext is not passed to the requested page (default.aspx, in my case.)

Code is as follows.

    Public Sub ProcessRequest(ByVal context As System.Web.HttpContext) Implements System.Web.IHttpHandler.ProcessRequest
            Dim requestedUrl As String
            Dim targetUrl As String
            Dim urlLength As Integer
            'Save settings which will be used while redirecting to appropriate page
            requestedUrl = context.Request.RawUrl
            If requestedUrl.IndexOf("?") >= 0 Then
                targetUrl = requestedUrl.Substring(0, requestedUrl.IndexOf("?"))
                targetUrl = requestedUrl
            End If
            If targetUrl = Nothing Or targetUrl.Length = 0 Then
                targetUrl = requestedUrl
            End If

Custom Control Design-Time SiteMap Provider Error


Greetings - I was referred here by MSDN forums hope this is the right place -  

I have a custom control (:WebControl) that renders web.sitemap in a specific way. While it runs error free and produces the expected result, at Design-Time it complains

Error Creating Control - MyControl  The provider 'AspNetXmlSiteMapProvider' specified for the defaultProvider does not exist in the providers collection.

I have discovered that the error is cause by this line of code:

string div = string.Format("<div class='{0}' id='{1}'>{2}</div>", this.CssClass, this.ID.ToString(), EnumerateNodesRecursive(SiteMap.RootNode, level));

or more specifically, by the reference to SiteMap.RootNode - I am not clear what is missing thoough because I have configured the SiteMapProvider in web.config as this:

        <add name="AspNetXmlSiteMapProvider" 
             type="System.Web.XmlSiteMapProvider, System.Web, Version=2.0.3600.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"

Custom Server Control Property not maintaining state


I have created a server control consisting of a TextArea and a div under it.  My goal is to create my own asp:TextArea type control.  the div is for a Character count of the text area and seems to work ok but i added a CharacterCountVisible property to the control that is always returning true.  See Proptery definition below


<Bindable(False), Category("Appearance"), DefaultValue("True"), Localizable(True)> Property CharacterCountVisible() As Boolean
        Return _CountBoxVisible
    End Get
    Set(ByVal value As Boolean)
        _CountBoxVisible = value
    End Set
End Property

Note the _CountBoxVisible variable is define inside the class as :

Dim _CountBoxVisible as Boolean = True

What I am trying to do is give the user/coder the option to show/utilize the char count feature.  Can make it disappear with textarea1.CharacterCountVisible = False but setting it to true will not make it display.


What am i missing
