WPF打印中的字體大小更改
[英]Font size changes in print wpf
問題描述
我有一個非常基本的WPF表格，我想打印
<Grid x:Name="grid">
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<TextBlock Text="Name" FontSize="20" HorizontalAlignment="Center" VerticalAlignment="Center" Grid.Column="0" Grid.Row="0"/>
<TextBox Text="Name" FontSize="20" HorizontalAlignment="Center" VerticalAlignment="Center" Grid.Column="1" Grid.Row="0" Height="60" x:Name="NameTb" Width="200" ScrollViewer.HorizontalScrollBarVisibility="Auto" ScrollViewer.VerticalScrollBarVisibility="Auto"/>
<TextBlock Text="ID" FontSize="20" HorizontalAlignment="Center" VerticalAlignment="Center" Grid.Column="0" Grid.Row="1"/>
<TextBox Text="ID" FontSize="20" HorizontalAlignment="Center" VerticalAlignment="Center" Grid.Column="1" Grid.Row="1" x:Name="IdTb" Height="60" Width="200" ScrollViewer.HorizontalScrollBarVisibility="Auto" ScrollViewer.VerticalScrollBarVisibility="Auto"/>
<TextBlock Text="Description" FontSize="20" HorizontalAlignment="Center" VerticalAlignment="Center" Grid.Column="0" Grid.Row="2"/>
<TextBox Text="Description" FontSize="20" HorizontalAlignment="Center" VerticalAlignment="Center" Grid.Column="1" Grid.Row="2" x:Name="DscTb" Height="60" Width="200" ScrollViewer.HorizontalScrollBarVisibility="Auto" ScrollViewer.VerticalScrollBarVisibility="Auto"/>
<Button Content="Print" Grid.Column="1" Grid.Row="3" Width="150" Height="30" Click="Print_Click"/>
</Grid>
后面的代碼是：
private void Print_Click(object sender,RoutedEventArgs e)
{
WebBrowser wb = new WebBrowser();
bool PrintFired = true;
StringBuilder printString = new StringBuilder("<head><meta http-equiv='Content-Type' content='text/html;charset=UTF-8'></head>");
printString.Append("<table border='0' margin-right ='20'><tr><td><b><font size='3'>" +"Name" + "</font>></b></td><td> </td><td>");
//printString.Append(explanation.EngagementName);
printString.Append("<font size='3'>" + NameTb.Text + "</font>");
printString.Append("</td></tr><tr><td></td></tr>");
printString.Append("<tr><td><b><font size='3'>" + "ID" + "</font></b></td><td> </td><td>");
printString.Append("<font size='3'>" + IdTb.Text + "</font>");
printString.Append("</td></tr><tr><td></td></tr>");
printString.Append("<tr><td valign ='top'><b><font size='3'>" + "Description" + "</font></b></td><td> </td><td>");
printString.Append("<font size='3'>" + DscTb.Text + "</font>");
printString.Append("</td></tr></table>");
wb.NavigateToString(printString.ToString());
var d = new System.Windows.Threading.DispatcherTimer();
d.Interval = TimeSpan.FromMilliseconds(250);
d.Tick += new EventHandler((sender1, args) =>
{
if (PrintFired == true && ((mshtml.IHTMLDocument2)(wb.Document)).readyState != "loading")
{
PrintFired = false;
mshtml.IHTMLDocument2 doc = wb.Document as mshtml.IHTMLDocument2;
doc.execCommand("Print", true, null);
d.Stop();
}
});
d.Start();
}
問題是當我在描述字段（或任何其他字段）中輸入大量文本時，字體大小會在打印時減小。
PS-您不必打印此文件，可以將其另存為PDF。

字體大小的更改是由縮放以適合頁面大小引起的。 如果要顯示如此長的字母序列，則需要包裝單元格的內容。
嘗試通過以下方式修改html：
"<table border='0' style=\"table-layout: fixed; width: 100%;\" margin-right='20'>"
.....
"<td style=\"word-wrap: break-word\" ><font size='3'>" + DscTb.Text + "</font></td>"
結果：
WPF字體大小不變
