[SharePoint 2010] 自定义字段类型开发(二)

jxh1230

　　在SharePoint 2010中实现View Action Button效果。
　　http://www.sharepointblogs.be/blogs/vandest/archive/2008/06/20/view-action-button.aspx
　　1. 创建自定义字段类ViewActionButton 继承自 SPTextField





    public class ViewActionButton : SPField
{
#region Constructors
public ViewActionButton(SPFieldCollection fields, string fieldName)
: base(fields, fieldName) { }
public ViewActionButton(SPFieldCollection fields, string typeName, string displayName)
: base(fields, typeName, displayName) { }
#endregion
#region Reimplementation of Get/Set Custom Property
public new void SetCustomProperty(string propertyName, object propertyValue)
{
Type type = typeof(SPField);
MethodInfo setField = type.GetMethod("SetFieldAttributeValue", BindingFlags.NonPublic | BindingFlags.Instance);
object o = setField.Invoke(this, new object[] { propertyName, propertyValue.ToString() });
}
public new string GetCustomProperty(string propertyName)
{
Type type = typeof(SPField);
MethodInfo getField = type.GetMethod("GetFieldAttributeValue", BindingFlags.NonPublic | BindingFlags.Instance, null, new Type[] { typeof(String) }, null);
object o = getField.Invoke(this, new object[] { propertyName });
return o as String;
}
#endregion
}

View Code 　　由于在SharePoint 2010中已经不推荐使用RenderPattern方式来呈现字段，需要将“CAMLRendering”设置成True，否则需要通过自定义XSLT来实现。



<Field Name="CAMLRendering">TRUE</Field>
　　请根据实际情况修改下列内容：



<Field Name="FieldTypeClass">CustomFieldProject.CustomFieldTypes.ViewActionButton, $SharePoint.Project.AssemblyFullName$</Field>
　　4. 创建自定义XSLT样式文件
　　如果已经CAMLRendering设置成True，则不必自定义XSLT样式。
　　目前仍然没有找到方法能够在XSLT中读取字段的自定义属性。
