The Syncfusion Xamarin.Forms platform includes the popular Charts and DataGrid controls as well as unique file-format libraries for manipulating ExcelWordPDF, and PowerPoint files. Recently, we published our fourth major release of 2021 with exciting new features.

Let’s see the new feature updates included in our Xamarin.Forms controls in this Essential Studio 2021 Volume 4 release.

Refer to the following code for how to get the unique ID of a selected shape in the code behind.

private void Editor_ItemSelected(object sender, ItemSelectedEventArgs args)
