    protected void gv_RowEditing(object sender, GridViewEditEventArgs e)

    {

        gv.EditIndex=e.NewEditIndex;

        BindData();

    }

--------------------编程问答-------------------- 请问你是在rowcommand事件里做的吗？
还是用控件自带的编辑？
--------------------编程问答-------------------- <EditItemTemplate >
<asp:TextBox id="txt" MaxLength="100" runat="server" Text='<%# Eval("NAME") %>' Width="86%">
</asp:TextBox>
</EditItemTemplate>
protected void gv_RowEditing(object sender, GridViewEditEventArgs e)
  {
  this.gv.EditIndex = e.NewEditIndex;
  BindData();
  }

  protected void gv_RowUpdating(object sender, GridViewUpdateEventArgs e)
  {
  this.gv.EditIndex = e.RowIndex;
  int id = int.Parse(this.gv.DataKeys[e.RowIndex].Value.ToString());
  string str = ((TextBox)this.gvTarget.Rows[e.RowIndex].FindControl("txt")).Text.Trim();

  this.gv.EditIndex = -1;
  BindData();
  }
  <asp:LinkButton ID="LinkButton1" runat="server" CommandName="edit" CausesValidation="false" OnClientClick="return confirm('确认要编辑吗？');">编辑</asp:LinkButton> --------------------编程问答-------------------- 能不能详细描述一下事发现场以及事发过程
