'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

Modal Popup and The Notification Area

Here I am covering
        1)Passing Url to Modal Popup from Server code in .cs file
          i)add the hiddenfield control to .aspx page          

and set value in cs file

hdnUrl.Value = "../Lists/ListName/NewForm.aspx?RootFolder=&";



        2)On Click of Ok button of Modal Popup Displaying the message in notification area which is part of sp2010 framework
Add following in Javascript tags
var url = document.getElementById('').value;

var options = {

url: url

title: "title",

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);

}


Invoke the function

asp:Label runat="server" ID ="lblr" Text ="Open Popup">

A Method To Get Selected Value in spuc:PeopleEditor control (Quickly)

-- Add Control in ascx

AllowEmpty="true" MultiSelect="false" SelectionSet="User" />

 

-- Get User value in ascx.cs

public SPUser GetUser(PeopleEditor p)

{

PickerEntity entPropMgr = (PickerEntity)p.ResolvedEntities[0];

SPFieldUserValue Proposalmgrvalue = new SPFieldUserValue(SPContext.Current.Web, Convert.ToInt16(entPropMgr.EntityData[PeopleEditorEntityDataKeys.UserId]), entPropMgr.Description);

if (Proposalmgrvalue != null)

return Proposalmgrvalue.User;

else

return SPContext.Current.Web.CurrentUser;



}

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.
