DataGrid: ItemSize by DataGridDisplayMode.Table

[alsoftera]

ItemSize is ignored by active DisplayMode="DataGridDisplayMode.Table"

ItemSize is a parameter only used in combination with Virtualize parameter. Internally the DataGrid uses the standard Blazor Virtualize component and we use our parameter to pass it's value to the Virtualize component.

Yes, I am using virtualization for the grid. Normally, ItemSize works as expected. However, when using multiline text and attempting to display a scrollbar, this parameter does not function correctly. The row height adjusts to fit the content, making the scrollbars ineffective. I want to set a constant maximum height for table rows. This issue may be related to setting the height after loading data with multiline text.

That is to be expected. Multiline makes each row fit its content. Ech row can have a different height and that does not work together with Virtualize where each row must be the same size (height)

Thanks for the quick response! I found a solution by using a TemplateColumn and wrapping the text in a div, which works well. However, is there a better alternative? Specifically, is it possible to wrap the content of the PropertyColumn in a div without relying on a TemplateColumn?

No, a PropertyColumn always just outputs the property. For changing that you have the TemplateColumn
