I need to develop a custom Web Part in C# to show the name and url of the list marching the specified type.
The idea being that the user will choose the ‘list type’ from a ‘checkbox list’ to select. The checkbox list contain ‘Event’, ‘Task’ and ‘Custom List’.
Since this is a checkbox list, the user will be able to select more than 1 list type. So for example, if the user selects ‘Event’ and ‘Custom List’, I am supposed to show them the name of all the Custom & Event List’s that are in the site, regardless of whether the list’s contain any item. For each list I need to supply a link (url) to the matching lists.
Any ideas on how to do this?
Thanks for the question. First and foremost I’d like to bring up the idea of not using C# for your webpart. Farm Solutions are no longer the “best practice” way to be building webparts in your SharePoint environment. For more information click here .
If you really need a webpart, I would look into the SharePoint-Add In Model and use JavaScript to do this. However, you should should use the REST APIs to do all of this work (whether in C# or JavaScript).
Please see the MSDN Rest API . In there you will see how to interact with the lists (the returned queries will have the template type).
Now, if you wish to go a different way… you would use SharePoint Search (Content Search Webpart (if you have licensing)). You could easily query ALL of the lists in your site using a simple REST Query using the Search API found here. You can find examples of using “Content_Class” to query your lists and by your templates here.
