How to create custom action for list items using Client Object Model

Requirement – …You need to add custom action to list items using client object model. This user custom action menu item will be added to drop-down menu which is displayed for list items.

using Microsoft.SharePoint.Client;
string urlWebsite = “http://xxxxxxxx:9999/”;
ClientContext clientContext = new ClientContext(urlWebsite);
Web oWebsite = clientContext.Web;
List oList = oWebsite.Lists.GetByTitle(“TestList”);
UserCustomActionCollection collUserCustomAction = oList.UserCustomActions;
UserCustomAction oUserCustomAction = collUserCustomAction.Add();
oUserCustomAction.Location = “EditControlBlock”;
oUserCustomAction.Sequence = 100;
oUserCustomAction.Title = “How to in SharePoint”;
oUserCustomAction.Url = @”http://howtoinsharepoint.blogspot.in/”;
oUserCustomAction.Update();
clientContext.Load(oList,
list => list.UserCustomActions);
clientContext.ExecuteQuery();

 

Location property specifies EditControlBlock,
Sequence specifies an order of placement in relation to other user custom actions,
Url specifies an absolute path to a page that defines the action.

Hope this helps…Happy Coding!!!!
