WPF DataGrid 的行数？

Question

How to count or return the last index of a DataGrid row? Apparently there's isn't a DataGrid.Count() property. I searched everywhere and I can't find an answer.

I could create a variable and use i++ as a counter for Row count, but doesn't a DataGrid has a built-in solution?

Answer 1

您可以使用DataGrid.Items.Count来获取项目的数字。

Answer 2

将计数存储在变量中

 int num=dataGrid.Items.Count

Answer 3

As TBohnen.jnr mentioned you should count the items in the bounded datasource. You can retrieve the datasource by casting dataGrid.DataContext to the appropriate Type (List, IEnumerable, or any other Type) and call .Count on that object. It shouldn't be very hard...

Answer 4

Items.Count returns 1 when you Datagrid is editable. This don't work for me.

Try this:

int num=dataGrid.ItemsSource.OfType<object>().Count()
