Using PowerShell Command for Visual Upgrade

Upgrade Visual from SharePoint 2007 to SharePoint 2010 after restoring Content Database on SharePoint 2010 Server.

When we restore content database in SharePoint 2010 from SharePoint 2007, it required to upgrade the Visual to Version 4. Following command will update all the site and sub-sites for provided content database.

$ContentDatabaseName = Get-SPContentDatabase WSS_Content_SharePoint_Database_Restore

$ContentDatabaseName.Sites | Get-SPWeb -limit all | ForEach-Object {$_.UIversion = 4; $_.UIVersionConfigurationEnabled = $false; $_.update()}

SPLongOperation error for ItemAdding Event In SharePoint 2010

We recently upgrade one of our project from SharePoint 2007 to SharePoint 210. In that project we user event handler for list. In ItemAdding event we use to create new site which takes times for creation. So we use SPLongOperation to handle it  but in SharePoint 2010 its same code gives error for "Object reference null" for SPLongOperation being statement.
So we had following workaround for this problem.

Create Web Part with following Code and add this web part to publishing Page

protected override void CreateChildControls(){
 if (this.Page.Request.QueryString["Processid"] != null)
            {           

                using (SPLongOperation ctx = new SPLongOperation(this.Page))
                {
                    try
                    {
                        ctx.LeadingHTML = "Please wait while your operation is being executed.";
                        ctx.TrailingHTML = "Site is being created. Please wait....";
                        ctx.Begin();

                        System.Threading.Thread.Sleep(5000);
                        string eid = this.Page.Request.QueryString["Processid"].ToString();
                        int count = 1;
                        while (true)
                        {
                            using (SPWeb web = SPContext.Current.Site.OpenWeb(SPContext.Current.Web.ID))
                            {
                                if (web.Properties[eid].ToString() != "Completed" && count < 18)
                                {

                                    System.Threading.Thread.Sleep(5000);
                                    count++;
                                }
                                else
                                    break;
                            }
                        }
                        ctx.End(this.Page.Request.QueryString["h"].ToString());
                    }
                    catch (Exception ex)
                    {
                        this.lbl.Text = ex.Message.ToString() + Environment.NewLine + ex.StackTrace.ToString() ;
                    }
                }
            }
}

In event handler modify ItemAdding event as follows

 public override void ItemAdding(SPItemEventProperties properties)
        {
            base.ItemAdding(properties);
            string guid
                = string.Format("ProcessId{0}_{1}", DateTime.Now.ToString("MMddyyyy"), Guid.NewGuid().ToString());
            Thread thread = new Thread(() => FunctionName(properties,guid));
            thread .Start();

            properties.Status = SPEventReceiverStatus.CancelNoError;
            properties.Cancel = true;
            SPUtility.Redirect({Url of page on which out put above webpart}, SPRedirectFlags.Default, _currentContext,string.Format ("Processid={0}&h={1}",guid , properties.RelativeWebUrl));
        }

Hope this work for you also

How to open hyperlinks into modal dialog box in SharePoint 2010

SharePoint 2010 provides new feature "Modal dialog box". In this blog we shows how to open hyperlinks in modal dialog box using simple jquery selector.

Declaration syntax for modal dialog box is as follows

//Using the DialogOptions class.
var options = SP.UI.$create_DialogOptions();

options.title = "Dialog box title";
options.width = 300;
options.height = 500;
options.url = "PageUrl";

SP.UI.ModalDialog.showModalDialog(options);


//Using a generic object.
var options = {
    title: "Dialog box title",
    width: 300,
    height: 500,
    url: "PageUrl" };
SP.UI.ModalDialog.showModalDialog(options);


Now we put above modal dialog syntax in jquery selector

$("[href(selection attributes)'Condition']").click ( function () {
                                                                   var options = {
                                                                   title: "Dialog box title",
                                                                   width: 300,
                                                                   height: 500,
                                                                   url: $(this).attr('href')
                                                                 };
                                                                   return false;// required to override default behavior of hyperlink tag
                                                                });

We have to open link which contains the query string parameters "ShowInDialog=1", then selection condition for it
$("[href*='ShowInDialog=1']")

Attribute for selection 
!= is not equal
^= is starts with
$= is ends with
*= is contains



Example for selecting hyper links which contains query string parameter "ShowInDialog=1" 
$("[href*='ShowInDialog=1']").click ( function () {

                                                                   var options = {
                                                                   title: "Dialog box title",
                                                                   width: 300,
                                                                   height: 500,
                                                                   url: $(this).attr('href')
                                                                 };
                                                                   return false;// required to override default behavior of hyperlink tag
                                                                });

Access Business Connectivity Services object using Client Application

Business Connectivity Service (BCS), enables users to read and write data from external systems - from web services, database, and Microsoft .NET Framework.
Following code snippet shows, how to access BCS object using Client Object Model

We already have BCS list named "Customer", contains columns Name, Address


// Specify your SharePoint Web Url

 ClientContext clientContext = new ClientContext("http://contoso:3434");
             
// Specify SharePoint list name
                List list = clientContext.Web.Lists.GetByTitle("Customer");

                CamlQuery query = new CamlQuery();
             
                query.ViewXml =
                    @"  <View>
                            <ViewFields>
                                <FieldRef Name='Name'/>
                                <FieldRef Name='Address'/>
                            </ViewFields>
                            <Query>
                                <Where>
                                <Eq>
                                <FieldRef Name='Name'/>
                                <Value Type='Text'>Jhon</Value>
                                </Eq>
                                </Where>
                            </Query>
                            <RowLimit>100</RowLimit>
                        </View>";

                ListItemCollection listItems = list.GetItems(query);

// Specify which field required to include in list object other wise it throws exception
                clientContext.Load(
                listItems, items => items.Include(
                 item => item["Name"], item => item["Address"]));


                clientContext.ExecuteQuery();

                foreach (ListItem listItem in listItems.ToList())
                {
                    Console.WriteLine("{0} ==> {1}", listItem["Name"].ToString(), listItem["Address"].ToString());
                }
