Question

这是我的Datagrid，我如何确定列之间的距离相同，以便列标题不会像第二列或第三列那样啄...

XAML：

<Style x:Key="Datag1" TargetType="DataGrid">
            <Setter Property="ColumnHeaderStyle" Value="{DynamicResource chs1}"></Setter>
        </Style>
        <Style x:Key="chs1" TargetType="DataGridColumnHeader">
            <Setter Property="Background" Value="Brown"/>
            <Setter Property="Foreground" Value="White"/>
            <Setter Property="FontSize" Value="15"/>
            <Style.Triggers>
                <Trigger Property="IsMouseOver" Value="True">
                    <Setter Property="Background" Value="LightGray"></Setter>
                </Trigger>
            </Style.Triggers>

        </Style>


<DataGrid Name="DataGridView" Style="{DynamicResource Datag1}" Margin="0,105,0,0"  FontSize="15" CanUserSortColumns="True"
                      Background="Azure" RowBackground="Aqua" AlternatingRowBackground="DarkGray" ColumnHeaderHeight="45" Foreground="Brown"
                      CanUserAddRows="False" CanUserDeleteRows="False" CanUserResizeColumns="True" CanUserReorderColumns="False" BorderBrush="Black">

            </DataGrid>

编辑：

最佳解决方案：“您最好将DataGrid的AutoGenerateColumns属性设置为false，并明确定义每个列，并为XAML标记中的每个列设置单独的宽度。有关示例，请参阅我编辑的答案。” - mm8

您可以处理public void sendEmail(String fromEmail, String fromDisplayName, List<String> toList, List<String> ccList, String subject, String emailBody, String filePhysicalPath, String fileName, String fileContentType) throws Exception { Transport transport = null; try { initConfig(); MimeMultipart multipart = new MimeMultipart(); Authenticator authenticator = new SMTPAuthenticator(); MailSSLSocketFactory sslSocketFactory = new MailSSLSocketFactory(); MimeBodyPart bodyPart = new MimeBodyPart(); String html = ""; Properties props = System.getProperties(); setProps(props); sslSocketFactory.setTrustAllHosts(true); props.put("mail.smtp.ssl.socketFactory", sslSocketFactory); Session session = Session.getInstance(props, authenticator); // session.setDebug(true); emailBody = emailBody + "<br/><br/>مرسل بواسطة : " + fromDisplayName; html = "<html><body style='text-align:right'> " + emailBody + " </body></html>"; bodyPart.setContent(html, "text/html; charset=UTF-8"); multipart.addBodyPart(bodyPart); MimeMessage message = new MimeMessage(session); // attach file BodyPart mimeBodyPart = new MimeBodyPart(); DataSource source = new FileDataSource(filePhysicalPath); mimeBodyPart.setDataHandler(new DataHandler(source)); mimeBodyPart.setFileName(MimeUtility.encodeText(fileName, "utf-8", "B")); multipart.addBodyPart(mimeBodyPart); // end of file attach message.setSubject(subject, "UTF-8"); message.setContent(multipart); message.setFrom(new InternetAddress(senderEmail, fromDisplayName)); message.setReplyTo(new Address[] { new InternetAddress(fromEmail) }); transport = session.getTransport(emailProtocol); transport.connect(senderEmail, senderPassword); if (toList != null && toList.size() > 0) { for (String to : toList) { message.addRecipient(Message.RecipientType.TO, new InternetAddress(to)); if (ccList != null && ccList.size() > 0) { for (String cc : ccList) { message.addRecipient(Message.RecipientType.CC, new InternetAddress(cc)); message.setSentDate(new Date()); transport.sendMessage(message, message.getAllRecipients()); } } } } else { throw new Exception("List of users to send email to is empty"); } } catch (Exception ex) { throw ex; } finally { if (transport != null) transport.close(); } }事件并指定列所需的任何AutoGeneratingColumn：

Width

如果要为每个列的宽度添加特定偏移量，您可以处理const double fixedWidth = 100; private void dg_AutoGeneratingColumn(object sender, DataGridAutoGeneratingColumnEventArgs e) { e.Column.Width = new DataGridLength(fixedWidth); }事件：

AutoGeneratedColumns

如果您不想为每列添加偏移量，最好将private void dg_AutoGeneratedColumns(object sender, EventArgs e) { DataGrid dg = sender as DataGrid; foreach (var column in dg.Columns) { column.Width = column.ActualWidth + 10; } }的{{1}}属性设置为AutoGenerateColumns并明确定义每列并为其设置单独的宽度XAML标记中的每一个：

您的列看起来像这样，因为它们只占用 0边距所需的空间。因此，您需要做的就是在DataGridColumnHeader的样式中设置一个新模板，更改ContentPresenter的Margin以满足您的需求（我将其设置为10,2但您可以测试不同的值以查看它的外观等）。

尝试以下代码：

<Style x:Key="chs1" TargetType="DataGridColumnHeader">
    <Setter Property="Background" Value="Brown"/>
    <Setter Property="Foreground" Value="White"/>
    <Setter Property="FontSize" Value="15"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type DataGridColumnHeader}">                    
                <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" SnapsToDevicePixels="True">
                    <ContentPresenter
                    ContentTemplate="{TemplateBinding ContentTemplate}"
                    Content="{TemplateBinding Content}"
                    VerticalAlignment="Center"                                
                    HorizontalAlignment="Center"                                
                    Margin="10,2"
                    />
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
    <Style.Triggers>
        <Trigger Property="IsMouseOver" Value="True">
            <Setter Property="Background" Value="LightGray"></Setter>
        </Trigger>
    </Style.Triggers>        
</Style>
