How to enable/disable buttons in ribbon conditionally?

By Gaurav Goyal - June 14, 2011

In this article I will cover how we can enable and disable the controls from ribbon based on any specific column value. For an instance I have a list column "State", if selected row is having status "active" then and then button should be enable in Ribbon, otherwise ribbon button should remain disable. For how to write Ribbon declaration please refer my previous articles. In above image you can see we have one button "New" in ribbon within group "Console". Please refer the source code for Ribbon's declaration. We are going to use delegate control for injecting ECMA script on fly for desired list. Below are the events causes ribbons to refresh so button can be turned enable/disable.

Opening a SharePoint 2010 dialog box for list form

By Gaurav Goyal - April 13, 2011

If you want to open a window in a dialog from clicking a link then simply use the following JavaScript as the href property. javascript: var options = {url: '/Lists/MyList/NewForm.aspx?IsDlg=1&ContentTypeId=0x001989BCF16D8914CAF8862B0C6C89E091E' , title: 'Showing List' }; void(SP.UI.ModalDialog.showModalDialog(options)) As you can see this is simply taking the script you would usually call and adapting it to work in the href of a hyperlink anchor. It needs to be all on one line and return void when called. So why might you want to do this? Many reasons. Perhaps you have a list with multiple content types and you wish to open the new item form in a dialog AND change the title from the default “[List Title] – New Item” depending on which content type the item is being created from. The snippet above illustrates this. Or perhaps you wish to open a document library in a dialog. Or even an external site. Also you can use following script in your code : p

Useful JavaScript global variables in SharePoint

By Gaurav Goyal - February 13, 2011

If you’re using custom JavaScripts with SharePoint 2010 some global JavaScript variables may come in handy. These variables work if you’re using SharePoint’s default or any other custom master page. L_Menu_BaseUrl – the base URL of the site / subsite. Very useful when you need to determine the absolute path of the site in JavaScript. Example: document.location = L_Menu_BaseUrl + ‘lists/calendar/allitems.aspx’ //redirects to Calendar list L_Menu_LCID – the LCID of the site you’re in. Useful if you need to determine the language of the site. The list of Locale IDs can be found here . _spUserId – the ID of the logged in user.
