There's a small snippet to check if current user permissions are enough to save list items. It can be used in SPFX webparts with PNP JS.

There are a lot of cases when you need to get the items by the author. For me the only correct way to get the SharePoint list items by user with CAML is like this:

<Where><Eq><FieldRef Name='Author' LookupId='TRUE' /><Value Type='Integer'>123</Value></Eq></Where>

You can delete timer job only with PowerShell. Why? I guess you know why 🙂 The most popular reason is the duplicating of timer jobs. To delete a timer job, you need to know the ID. And you can get it also with PowerShell or with GUI.

Below you can find a PowerShell script to copy items from one SharePoint list at one site to another SharePoint list in another site. I use it with several modifications to work with the data in test environments.

I had a SharePoint online list and I added a new column into it. And then I wanted to work with a data, which is close to be real. So I needed to generate the data and insert it into the list. For the tasks like this I like to use division by module to create semi-random data.

While writing the script to create lists for my solution for SharePoint Online I had to rename Title field in a list. It's not so obviously as just to create a new field.

I used EventCalendar component with resources and timeline view, the default interval is 1 month, I also add week numbers to the header. I wanted to fit the calendar to the page without horizontal scroll.

Many times I told myself not to work with SharePoint, but it's forever with me 🙂
My colleague asked to help him with a problem with modern lists. There some simple fields, without lookups. But there's an error in displaying items. I spent about an hour to determine the problem - created a copy of the list, removed all items, added items with only 1 filled field. It worked in classic view, but not in modern.

Once I tried to make the application to migrate a custom data source from SharePoint 2010 to SharePoint 2019 on-premise. To make it easier, I decided to make to separate solutions – the first one to export the data from SharePoint 2010 from the list to JSON and attachments to local folder(CSOM for SharePoint 2010 sucks) and the utility to import data to SharePoint 2019 via REST.

With SharePoint 2010 you can disable usage of modal windows in List settings. But if you use calendar view, it does not matter what you have installed in the settings – all the list forms will be opened in modal windows. How to disable them?
