这是telerik给我的:
使用默认的 MergeFields,无法更改字段的显示名称片段以获得更友好的外观。如果您通过从 MergeField 类派生来实现自定义 MergeField,这应该是可能的。这是一个示例实现,展示了如何做到这一点:
public class CustomMergeField : MergeField
{
private const string CustomFieldName = "CustomField";
static CustomMergeField()
{
CodeBasedFieldFactory.RegisterFieldType(CustomMergeField.CustomFieldName, () => { return new CustomMergeField(); });
}
public override string FieldTypeName
{
get
{
return CustomMergeField.CustomFieldName;
}
}
public override Field CreateInstance()
{
return new CustomMergeField();
}
protected override DocumentFragment GetDisplayNameFragment()
{
return base.CreateFragmentFromText(string.Format(Field.DisplayNameFragmentFormat, this.GetFriendlyFieldName(this.PropertyPath)));
}
private string GetFriendlyFieldName(string fieldName)
{
int lettersInEnglishAlphabet = 26;
List<char> separators = new List<char>(lettersInEnglishAlphabet);
for (int i = 0; i < lettersInEnglishAlphabet; i++)
{
separators.Add((char)('A' + i));
}
StringBuilder newFieldName = new StringBuilder();
int previousIndex = 0;
for (int i = 1; i < fieldName.Length; i++)
{
if (separators.Contains(fieldName[i]))
{
if (previousIndex > 0)
{
newFieldName.Append(" ");
}
newFieldName.Append(fieldName.Substring(previousIndex, i - previousIndex));
previousIndex = i;
}
}
newFieldName.Append(" " + fieldName.Substring(previousIndex));
return newFieldName.ToString();
}
}
请注意,当 DisplayMode 为 Code 时显示的片段无法更改。
至于您的其他问题,您可以更改下拉按钮的内容以显示字段的友好名称并以下列方式包含滚动条: 1. 首先,从 XAML 中删除按钮与 InsertMergeFieldEmptyCommand 的绑定并给出它是一个名称(例如 insertMergeField)。2. 接下来,在代码隐藏中添加以下代码:
AddMergeFieldsInDropDownContent(this.insertMergeFieldButton);
private void AddMergeFieldsInDropDownContent(RadRibbonDropDownButton radRibbonDropDownButton)
{ 网格网格 = 新网格();grid.RowDefinitions.Add(new RowDefinition() { Height = new GridLength(100, GridUnitType.Pixel) });
ScrollViewer scrollViewer = new ScrollViewer();
scrollViewer.VerticalScrollBarVisibility = ScrollBarVisibility.Auto;
StackPanel stackPanel = new StackPanel();
foreach (string fieldName in this.editor.Document.MailMergeDataSource.GetColumnNames())
{
RadRibbonButton fieldButton = new RadRibbonButton()
{
Text = this.GetFriendlyFieldName(fieldName),
Size = ButtonSize.Medium,
HorizontalAlignment = HorizontalAlignment.Stretch,
HorizontalContentAlignment = HorizontalAlignment.Left
};
fieldButton.Command = this.editor.Commands.InsertFieldCommand;
fieldButton.CommandParameter = new MergeField() { PropertyPath = fieldName };
//or
//fieldButton.CommandParameter = new CustomMergeField() { PropertyPath = fieldName };
stackPanel.Children.Add(fieldButton);
}
stackPanel.HorizontalAlignment = System.Windows.HorizontalAlignment.Stretch;
scrollViewer.Content = stackPanel;
grid.Children.Add(scrollViewer);
radRibbonDropDownButton.DropDownContent = grid;
}
当然,您可以优化 GetFriendlyName 方法的代码并以两种类都可用的方式添加它。
