Repeater control implements sample code for editing, updating, deleting, and so on

  How do I implement edit, update, and delete functions like the GridView control in a Repeater control? Here is a good example, interested friends can refer to, I hope to help you.

The code is as follows: protected void Page_Load (object sender, EventArgs e)   {  if (! Page.IsPostBack)   {  Bindgrid (); } }  private void Bindgrid ()   {  string strSQL = "SE Lect * FROM [User] ";  oledbconnection objconnection = new OleDbConnection (Getstrconnection ());  Objconnection.open ();  OleDbCommand objcommand = new OleDbCommand (strSQL, objconnection);  OleDbDataReader Reader = Objcommand.executereader (commandbehavior.closeconnection);  Rptuser.datasource = reader;  Rptuser.databind (); }  protected void Rptuser_itemdatabound (object sender, RepeaterItemEventArgs e)   {   if (E.item.itemtype = ListItemType.Item | | e.item.itemtype = = listitemtype.alternatingitem)   {  System . Data.Common.DbDataRecord record = (System.Data.Common.DbDataRecord) e.item.dataitem;  int userId = Int. Parse (record["UserId"). ToString ());  if (userId!= ID)   {  ((panel) E.item.findcontrol ("Plitem")). Visible = true;  (panel) E.item.findcontrol ("Pledit"). Visible = false; }  else  {  (panel) E.item.findcontrol ("Plitem")). Visible = false;  (panel) E.item.findcontrol ("Pledit"). Visible = true; } } }  protected void Rptuser_itemcommand (object source, RepeaterCommandEventArgs e)   {  if (e.commandname = = "Edit")   {  id = Int. Parse (E.commandargument.tostring ()); }  else if (E.commandname = "Cancel")   {  id = -1; }&nbs P else if (e.commandname = "Update")   {  String name = ((TextBox) This.rptuser.items[e.item.itemindex]. FindControl ("Txtname")). Text.trim ();  String email = ((TextBox) This.rptuser.items[e.item.itemindex]. FindControl ("Txtemail")). Text.trim ();  string qq = ((TextBox) This.rptuser.items[e.item.itemindex]. FindControl ("Txtqq")). Text.trim ();  string strSQL = "UPDATE [User] SET name= @Name, email= @Email, qq= @QQ WHERE userid= @UserId";  OleDbConnection objconnection = New OleDbConnection (Getstrconnection ());  OleDbCommand objcommand = new OleDbCommand (strSQL, objConnection);   OBJCOMMAND.PARAMETERS.ADD ("@Name", Oledbtype.varwchar);  objcommand.parameters["@Name"]. Value = name;  objCommand.Parameters.Add ("@Email", Oledbtype.varwchar);  objcommand.parameters["@Email"]. Value = email;  objCommand.Parameters.Add ("@QQ", Oledbtype.varwchar);  objcommand.parameters["@QQ"]. Value = qq;  objCommand.Parameters.Add ("@UserId", OleDbType.Integer);  objcommand.parameters["@UserId"]. Value = Int. Parse (E.commandargument.tostring ());  Objconnection.open ();  objcommand.executenonquery ();  Objconnection.close (); }  else if (e.commandname = = "Delete")   {  string strSQL = "Delete * FROM [ R] WHERE userid= @UserId ";  OleDbConnection objconnection = new OleDbConnection (Getstrconnection ());  OleDbCommand objcommand = new OleDbCommand (strSQL, objconnection);  objcommand.parameters.ADD ("@UserId", OleDbType.Integer);  objcommand.parameters["@UserId"]. Value = Int. Parse (E.commandargument.tostring ());  Objconnection.open ();  objcommand.executenonquery ();  Objconnection.close (); }  Bindgrid (); }  private String getstrconnection ()   {  return " Provider=Microsoft.Jet.OLEDB.4.0;Data source= "+ Server.MapPath (" ~/database/test.mdb "); }    < </code>form id= "Form1" runat= "Server" >  <</code>asp:repeater id= "Rptuser" runat= "Server" Onitemcommand= "Rptuser_itemcommand"   onitemdatabound= "Rptuser_itemdatabound" >  <</CODE> headertemplate>  <</code>table width= "960" align= "Center" cellpadding= "3" cellspacing= "1" style= " Background-color: #ccc; " >  <</code>thead style= "Background-color: #eee;" >  <</CODE>tr>  <</code>th width= "10%" >  user id  </</code>th >  <</CODE>TH>&NBSp User name   </</CODE>th>  <</code>th width= "22%" >  Mail   </</code>th >  <</code>th width= "20%" >  qq  </</CODE>th>  <</code>th Width= "15%" >  registration time   </</CODE>th>  <</code>th width= "12%" >  operation   </</CODE>th>  </</CODE>tr>  </</CODE>thead>  <</CODE> Tbody style= "Background-color: #fff;" >  </</CODE>HeaderTemplate>  <</CODE>ItemTemplate>  <</CODE> Asp:panel id= "Plitem" runat= "Server" >  <</code>tr style= "Text-align:center;" >  <</CODE>td>
