当点击确认按钮

Question

我有一个项目，该项目是文件同治系统在这itry到apporve /拒绝文件和FR这 我创造批准和拒绝文档

ALTER procedure [dbo].[sprejectapprove] 
     @UserID int, 
     @DocID int, 
     @ApproveType nvarchar(50) 
as 
    Insert into Approval(UserID,DocID,ApproveType) 
    values(@UserID,@DocID,@ApproveType) 

SP批准无响应：

ALTER procedure [dbo].[spinsertapprove] 
    @UserID int, 
    @DocID int, 
    @ApproveType nvarchar(50) 
as 
    Insert into Approval(UserID,DocID,ApproveType) 
    values(@UserID,@DocID,@ApproveType) 

和代码是

protected void GrdFileApprove_RowCommand(object sender, GridViewCommandEventArgs e) 
{ 
    if (e.CommandName == "_Approve") 
    { 
     //using (SqlConnection con = DataAccess.GetConnected()) 
     using (SqlConnection con = 
       new SqlConnection(ConfigurationManager.ConnectionStrings["mydms"].ConnectionString)) 
     { 
      try 
      { 
       int rowindex = Convert.ToInt32(e.CommandArgument); 
       GridViewRow row = (GridViewRow)  

      ((Control)e.CommandSource).NamingContainer; 
       LinkButton Prove_Button = 
       (LinkButton)row.FindControl("BtnApprove"); 
       SqlCommand cmd = new SqlCommand("spinsertapprove", con); 
       cmd.CommandType = CommandType.StoredProcedure; 
       int result = cmd.ExecuteNonQuery(); 
       if (result != 0) 
       { 
        GrdFileApprove.DataBind(); 
       } 
      } 

      catch 
      { 
       apfi.Text = "Not Approve"; 
      } 
      finally 
      { 
       con.Close(); 
      } 
     } 
    } 


    else if (e.CommandName == "_Reject") 
    { 
     using (SqlConnection con = 
        new SqlConnection(ConfigurationManager.ConnectionStrings["mydms"].ConnectionString)) 
     { 
      try 
      { 
       int rowindex = Convert.ToInt32(e.CommandArgument); 
       GridViewRow row = (GridViewRow) 
       ((Control)e.CommandSource).NamingContainer; 
       LinkButton Prove_Button = (LinkButton)row.FindControl("Button1"); 
       SqlCommand cmd = new SqlCommand("sprejectapprove", con); 
       cmd.CommandType = CommandType.StoredProcedure; 
       int result = cmd.ExecuteNonQuery(); 
       if (result != 0) 
       { 
        GrdFileApprove.DataBind(); 
       } 
      } 

      catch 
      { 
       apfi.Text = "Rejct"; 
      } 
      finally 
      { 
       con.Close(); 
      } 
     } 
    } 
} 

当我得不克码并点击批准或拒绝按钮，它无法继续进行，也没有给我任何错误

你不加入任何参数值，以您的SQL调用，因此存储过程可能根本不会被调用，因为您没有定义任何默认值。

你需要调用之前添加每个参数如下：

myCommand.Parameters.AddWithValue("@UserID", userId); 
myCommand.Parameters.AddWithValue("@DocID", docId); 
myCommand.Parameters.AddWithValue("@ApproveType", "Approve"); 

与最后一个是：

myCommand.Parameters.AddWithValue("@ApproveType", "Reject"); 

为拒绝的情况。

这些值需要从存储的地方读取，而不是被硬编码。
