SharePoint 2010 Simple Web parts

Simple Web partsWhat are web parts?• Web Part is also called a Web Widget, is an ASP.NET

server control which is added to a Web Part Zone on Web Part Pages by users at run time. It enable end users to modify the content, appearance, and behavior of Web pages directly from a browser.

Possible scopes• Site Level.

Simple Web partsTwo types of web parts

• Pure ASP.Net based web parts Derived from:- System.Web.UI.WebControls.WebParts.WebPart

– Generic web parts, that can be used in SharePoint and outside the SharePoint domain.

• SharePoint based web parts Derived from:- Microsoft.SharePoint.WebPartPages.WebPart

– Only used in the SharePoint domain.

Simple Web partsFurther Categorization in Web parts

• Web parts - A class derived from “Webparts” class

• Visual web parts - A class derived from “Webparts” but also contains a user control in this web part. - Can’t be used in sandboxed solutions.

Define properties in web parts

The WebBrowseable attribute specifies that the decorated property should appear in the editor component of the web part. It only allows the end user to modify the property and does nothing about persistence.

The Personalizable attribute specifies that the value of the decorated property must be persisted in the SharePoint backend, either in the user store (by default) or in the shared store (if the Shared scope is specified). It only cares about persistence and does nothing about the property presence in the editor component.

So, if you decorate a property with [WebBrowsable] and not [Personalizable], the end user will be able to modify it in the editor component but its new value won't be persisted.

Conversely, if you decorate a property with [Personalizable] and not [WebBrowsable], its value will be persisted but the end user won't be allowed to modify it.

SharePoint 2010 Advance Level Web parts

Advance Level Web partsAdvance Level web parts?• Web part which contains toolpart, or we add

some custom controls in Web part Editor Tool part section.

Advance Level Web partsAdvance Level web parts?• Web part which contains Custom Webpart Editor Section

• Two ways to create Custom Editor Part / Toolpart of Web part– By inheriting class from

“Microsoft.SharePoint.WebPartPages.ToolPart”

– By Implementing Interface “IWebEditable” on Toolpart class

• Layout – Visible on Page – Direction– Zone– Part Order

• Advanced – Allow Minimize – Allow Close – Allow Zone Change– Allow Export Sensitive Properties – Detail Link – Description – Help Link – Icon File (Large) – Icon File (Small) – Missing Assembly Error – Target Audiences

Advance Level Web parts using Toolpart class

CustomPropertyToolPart

An additional ToolPart that is added when custom properties are added to the WebPart programmatically.

Example:- First Name, Last Name

Advance Level Web parts using Toolpart class

CustomToolPart

A toolpart which you have programmatically created and want to add in web part editor part.

Example:- Derived Classes from “Microsoft.SharePoint.WebPartPages.ToolPart” wants to add in the Web part’s Editor section.

Advance Level Web parts using Toolpart class

public override Microsoft.SharePoint.WebPartPages.ToolPart[] GetToolParts(){ PersonDetailsToolPart CustomToolPart_ = new PersonDetailsToolPart(); CustomToolPart_.Title = "Company Details";

Microsoft.SharePoint.WebPartPages.ToolPart[] toolParts = new Microsoft.SharePoint.WebPartPages.ToolPart[3]; toolParts[0] = new Microsoft.SharePoint.WebPartPages.WebPartToolPart(); toolParts[1] = new Microsoft.SharePoint.WebPartPages.CustomPropertyToolPart(); toolParts[2] = CustomToolPart_;

return toolParts;}

Override the “GetToolParts()” method in order to add the custom toolpart in to your web part editor part section.

Common Webpart Propertiesthis.AllowMinimize = true/falsethis.AllowHide = true/false;this.AllowClose = false;this.ChromeType = PartChromeType.None; (if user wants to remove the border of the web part )

Advance Level Web parts using IWebEditable Interface

Steps

- The web part which has the Custom Editor Part must implement the “IWebEditable “interface.

#region IWebEditable Members

EditorPartCollection IWebEditable.CreateEditorParts(){ // Adding your custom web part editor part (Example:- CustomEditor) List<EditorPart> editors = new List<EditorPart>(); editors.Add(new CustomEditor()); return new EditorPartCollection(editors);}

object IWebEditable.WebBrowsableObject{ get { return this; } // what is being edited :- Returning the Web part itself.} #endregion

Advance Level Web parts using IWebEditable Interface

Steps- The Custom Editor Webpart must be inherited

from “EditorPart” class.- It must overrides two methods. 1- ApplyChanges Used for copy content from Editor Part to Web part. 2- SyncChanges Used for Copy content from Web part to Editor Part.
