'value does not fall in expected range' When assigning SPUser to ListItem

If you try to assign,
ListItem["UserField"]=SPContext.Web.CurrentUser
And you get th Error  " value does not fall in expected range"
Cause:  ListItem is in different Sitecollection
So Directly You can not assign current user.
Resolution:
SPUser differntSiteCollectionUser = differentWeb.SiteUsers.GetByEmail(currentUserMailId);-->GetmailID with SPFieldUserValue

allowMaximize: true,

showClose: true,

dialogReturnValueCallback: refreshCallback

};

function open() { SP.UI.ModalDialog.showModalDialog(options); }

function silentCallback(dialogResult, returnValue) {

}

function refreshCallback(dialogResult, returnValue) {

SP.UI.Notify.addNotification('Successful!');

SP.UI.ModalDialog.RefreshPage(SP.UI.DialogResult.OK);

SPDispose Check Results

- I have noticed that objects(SPWeb) created inside for loops are not being disposed. These objects need to be disposed eventhough you main block of code is "Using".

- Also when you use following snippet it will not dispose SPSite object:

using(SPWeb oWeb=new SPSite("http://abc").openWeb())

{

-------

}
Here SPSite object is not disposed so follow below style in case of such scenerios:

using(SPSite oSite=new SPSite("url"))

{

using(SPWeb oWeb=oSite.OpenWeb())

{

------

}

}

This will solve the problem of disposing.
- Do not use "Using" when you work with SPContext. As SPContext are disposed automatically and if you use withing Using block than it will dispose SPWeb object and page will not work.

SharePoint Manger 2007 For Adding Customized content Type

Hello All,

First let me explain, what is content Type? Its FAQ and very important to understand,
A content type is a reusable collection of settings you want to apply to a certain category of content. Content types enable you to manage the metadata and behaviors of a document or item type in a centralized, reusable way.
for the exact definition visit

For Customizing the New\Edit\Display Forms of Custom List
use SharePoint Manager which can be downloaded at codeplex
its a great tool for customizing content Types
Find more links on google for how to do it
