前些时候写DataGrid合并行效果，在网上偶然必然了这个接口的实现。
Itemplate例子Msdn
1using System; 2using System.Web; 3using System.Web.UI; 4 5namespace TemplateControlSamples { 6 7 public class TemplateItem : Control, INamingContainer { 8 private String _message = null; 910 public TemplateItem(String message) {11 _message = message;12 }1314 public String Message {1516 get {17 return _message;18 }19 set {20 _message = value;21 }22 }23 }2425 [System.Security.Permissions.PermissionSet(System.Security.Permissions.SecurityAction.Demand, Name="FullTrust")]26 [ParseChildren(true)]27 public class Template1 : Control, INamingContainer {2829 private ITemplate _messageTemplate = null;30 private String _message = null;3132 public String Message {3334 get {35 return _message;36 }37 set {38 _message = value;39 }40 }4142 [43 PersistenceMode(PersistenceMode.InnerProperty),44 TemplateContainer(typeof(TemplateItem))45 ]46 public ITemplate MessageTemplate {47 get {48 return _messageTemplate;49 }50 set {51 _messageTemplate = value;52 }53 }5455 protected override void CreateChildControls() {5657 // If a template has been specified, use it to create children.58 // Otherwise, create a single LiteralControl with the message value.5960 if (MessageTemplate != null) {61 Controls.Clear();62 TemplateItem i = new TemplateItem(this.Message);63 MessageTemplate.InstantiateIn(i);64 Controls.Add(i);65 }66 else {67 this.Controls.Add(new LiteralControl(this.Message));68 }69 }70 }71}
感觉挺有意思，不过还没有时间仔细的研究。。先做个标记，回头有时候或有必要的时候在研究下。。。
