I'm working with PrintPreviewDialog and want to tweak its initial presentation from the default. So far, I've done this:
我正在使用PrintPreviewDialog，并希望从默认情况调整其初始演示文稿。到目前为止，我已经这样做了：
PrintPreviewDialog dlg = new PrintPreviewDialog();
dlg.WindowState = FormWindowState.Maximized;
dlg.PrintPreviewControl.Zoom = 1.0;
...which gives me the presentation I want, but when the dialog is opened, the zoom control has the "Auto" choice selected, not 100% as would correspond to the zoom value of 1.0. How can I get at the zoom control to show 100% as the currently selected zoom setting so as not to confuse the user?
...它给了我想要的演示文稿，但是当打开对话框时，缩放控件选择了“自动”选项，而不是100％，与缩放值1.0相对应。如何在变焦控制中显示100％作为当前选择的缩放设置，以免混淆用户？
BTW, this is VS 2010 .NET 4
顺便说一句，这是VS 2010 .NET 4

Maybe setting AutoZoom = false will help:
也许设置AutoZoom = false会有所帮助：
dlg.PrintPreviewControl.AutoZoom = false;
The PrintPreviewControl should reflect the value of AutoZoom and Zoom but it doesn't. That's a strange thing in its design. However after a search on this control, I've found that we can access to the ToolStrip of the PrintPreviewDialog. This dialog has 2 child controls by default. The first is the PrintPreviewControl which is exposed via the property PrintPreviewControl, the second is the ToolStrip. By looping through the Items, you can find the exact ToolStripSplitButton (the Zoom button) and by looping through the DropDownItems of that splitbutton, we can find the exact 100% toolstripdropdownitem and call PerformClick to check it. However by default, I think we know the index of the item beforehand and the following code would work:

ToolStripSplitButton zoomButton = ((ToolStrip)dlg.Controls[1]).Items[1] as ToolStripSplitButton;
zoomButton.DropDownItems[4].PerformClick();//Check the 100% item in the zoom list
