In Gridview control, how to multi select the gridview items using mouse click-drag selection, like we select files/folders in windows explorer using mouse?

Like this Selection

If there is no mouse click-drag multi-selection available, please provide any code/idea of how to implement that myself.

What I have tried:

In Microsoft's docs, I could see only Single/Multiple/Extended selection, in which user has to click each Gridviewitem's checkbox to multi-select. i.e. I should tick the checkboxes in each GridViewitem, which takes more time if select more than 20 or 30 items. This seems an in-efficient way.

Haven't worked with UWP before, but looking at the docs, it seems like the drag and drop functionality is not supported by the regular GridView. In this case, you may need to build a custom control by extending the GridView control just like in this example: Extending GridView with Drag and Drop for Grouping and Variable Sized Items[^]

Looking back at the documentation, To do multiple selection, you have to use SHIFT or CTRL keys. Since a UWP app can target different devices including touch screens, they've designed it that way.

Also, I'm not sure if this will work for you: https://stackoverflow.com/questions/35890625/win-rt-xaml-gridview-drag-select-multiple-items
