代码落后......

code behind...

protected void Page_Load(object sender, EventArgs e)
      {
          Bind();
      }
      public void Bind()
      {
          try
          {
              CTeam cTeam = new CTeam();
              GridviewTeams.DataSource = cTeam.GetAllTeams();
              GridviewTeams.DataBind();
          }
          catch (Exception err)
          {
              Response.Write(err.Message);
          }
      }
      protected void BtnAdd_Click(object sender, EventArgs e)
      {
          CTeam cteam = new CTeam();
          cteam.AddTeams(tbxTeamName.Text,tbxTeamEmail.Text);
          Bind();
      }
      protected void GV_RowDeleting(object sender, GridViewDeleteEventArgs e)
      {
          CTeam cteam = new CTeam();
          int indexrow = e.RowIndex;
          short tid = short.Parse(((Label)GridviewTeams.Rows[indexrow].FindControl("GV_lblTeamID")).Text);
          cteam.DeleteTeams(tid);
          Bind();
      }
      protected void GV_RowEditing(object sender, GridViewEditEventArgs e)
      {
          GridviewTeams.EditIndex = e.NewEditIndex;
          Bind();
      }
      protected void GV_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)

谢谢你。

Hi...
For insert,edit,update and delete data in gridview using asp.net.
http://www.aspdotnet-suresh.com/2011/02/how-to-inserteditupdate-and-delete-data.html[^]
Thank u.

亲爱的你的代码是完美的但是你用你的代码犯了一些小错误首先只是添加Text ='<％＃Bind（ teamID）％>'到EditItemTemplate内的每个文本框，因为当你点击编辑时，现有文字会显示在文本框上。



第二个是你必须添加找到控制语句如下：



TextBox tname =（TextBox）GridviewTeams.Rows [e.RowIndex] .FindControl（tbx EditTeamName）;

TextBox temail =（TextBox）GridviewTeams.Rows [e.RowIndex] .FindControl（tbxEditTeamEmail）;





我希望它对你有帮助.......： - ）

Dear your code is perfect but you make some small mistakes over their with your code first one is firstly just add Text='<%# Bind("teamID") %>' to every textbox inside of EditItemTemplate because when you click on edit existing text will display on textbox.

Second one is you have to add find control statement as like:

TextBox tname = (TextBox)GridviewTeams.Rows[e.RowIndex].FindControl("tbxEditTeamName");
TextBox temail = (TextBox)GridviewTeams.Rows[e.RowIndex].FindControl("tbxEditTeamEmail");


I hope it's helping to you.......:-)
