Hello Alex,
Thank you for writing back.
There is no way to preview the changes without actually applying them to the document. I can suggest adding
your save logic at the end of the
OnShowPrintSettingsDialog method. This way it will be always in sync with the printed or previewed document. Additionally, you may also consider adding the button in the command bar as I suggested in my second post.
In case that does not fit your project and you insist on using the separate button you can apply and save the changes this way:
public class MyRadPrintPreviewDialog : RadPrintPreviewDialog
{
Form dialog;
protected override void OnShowPrintSettingsDialog()
{
if (this.Document == null)
{
return;
}
dialog = this.Document.AssociatedObject.GetSettingsDialog(this.Document);
RadForm radDialog = dialog as RadForm;
RadButton print = radDialog.Controls["buttonPrint"] as RadButton;
RadButton saveBtn = new RadButton() { Text = "MyBtn" };
saveBtn.Parent = radDialog;
saveBtn.Size = print.Size;
saveBtn.Location = new Point(print.Location.X - print.Size.Width - 6, print.Location.Y);
saveBtn.Click += saveBtn_Click;
if (radDialog != null)
{
radDialog.ThemeName = this.ThemeName;
}
if (dialog.ShowDialog() == DialogResult.OK)
{
this.Document.PrinterSettings.PrintRange = System.Drawing.Printing.PrintRange.AllPages;
this.printPreviewControl.InvalidatePreview();
this.GetType().BaseType.GetMethod("UpdatePageCount", BindingFlags.Instance | BindingFlags.NonPublic).Invoke(this, new object[] { });
}
}
private void saveBtn_Click(object sender, EventArgs e)
{
typeof(PrintSettingsDialog).GetMethod("ApplySettings", BindingFlags.Instance | BindingFlags.NonPublic).Invoke(dialog, new object[] { });
this.Document.PrinterSettings.PrintRange = System.Drawing.Printing.PrintRange.AllPages;
this.printPreviewControl.InvalidatePreview();
this.GetType().BaseType.GetMethod("UpdatePageCount", BindingFlags.Instance | BindingFlags.NonPublic).Invoke(this, new object[] { });
//Execute your logic for saving the settings
dialog.Close();
}
}
I hope this helps. Please let me know if you need further assistance.
