back-end code：
private void OnSizeChanged(object? sender, SizeChangedEventArgs e)
{
var newWidth = e.NewSize.Width;
if (GridContentColumn==null)
return;
if (newWidth <= ScreenSize.Md)
{
GridContentColumn.Columns = 3;
}
else if (newWidth <= ScreenSize.Lg)
{
GridContentColumn.Columns = 4;
}
else if (newWidth <= ScreenSize.Xl)
{
GridContentColumn.Columns = 6;
}
else
{
GridContentColumn.Columns = 8;
}
}
The GridContentColumn is always null.
I roughly understand that the components generated by ItemsControl do not include UniformGrid, so how should I obtain the UniformGrid component?
