initially set it to 0
and reset it after ppd.ShowDialog();
ppd.ShowDialog();
border = 0;
UPDATE
Looks like PrintPreviewDialog
doesn't support much as you (and many others expect), it's up to the user (not to programmer). You can try this a little hacky stuff:
//code in your button5_Click
ToolStripButton onePageButton = ((ToolStrip)ppd.Controls[1]).Items[3] as ToolStripButton;
BeginInvoke((Action)(() => onePageButton.PerformClick()));
ppd.ShowDialog();
UPDATE
To intercept the Clicking
on the Print button
, you have to add a little much more code. You have to detect the click before the Click
is fired on the item (print button), show the message box asking for confirmation and re-click
the item if user agrees. Here is the code for you:
//Use this class to add message interceptor into your ToolStrip message loop
public class NativeToolStrip : NativeWindow {
ToolStrip ts;
bool letClicked;
protected override void OnHandleChange() {
base.OnHandleChange();
Control c = Control.FromHandle(Handle);
ts = c as ToolStrip;
}
protected override void WndProc(ref Message m) {
if (m.Msg == 0x202&&!letClicked) {//WM_LBUTTONUP = 0x202
int x = m.LParam.ToInt32() & 0x00ff;
int y = m.LParam.ToInt32() >> 16;
ToolStripItem item = ts.GetItemAt(new Point(x, y));
//check if the first item (the Print Button) is clicked
if (item != null && ts.Items.IndexOf(item) == 0) {
if (MessageBox.Show("Do you want to print?", "Print confirmation", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.No)
return;//discard message
else {
letClicked = true;
item.PerformClick();
}
}
}
base.WndProc(ref m);
if (letClicked) letClicked = false;
}
}
//This code should be done somewhere like in your form constructor
//BUT your PrintPreviewDialog should also be declared once in the form scope
//You can also place this in your button5_Click BUT it's not recommended
ToolStrip ts = (ToolStrip)ppd.Controls[1];
new NativeToolStrip().AssignHandle(ts.Handle);
