Hey,
Today I'm planning to present "How to do a webpart using client object model, which is capable of replicating multiple time within a same page". Most of Sharepoint developers developing webparts using client object model with ECMA scripting. However duplicate webparts cant included in a same page.
But below is a nice approach on solving above issue.
1.Create a visual webpart which is inheriting from System.Web.UI.WebControls.WebParts.WebPart
2.In the .cs file just add hidden property with webpart's clienID and
3.Read that client id to commit any changes.
I have attached a sample project consisting this solution. Open the solution from VS 2010.
File structure:
BlogViewer.cs - holding one webpart property, saving the property value to a hidden field, registering the js file, register main function of js - which is having the webpart client id to refer the control/s.
comscript.js - get the webpart client id, access webpart property value - which is already write to the hidden field, then populate the html file inside the webpart div.
control.htm - holding the markup of the webpart
