C# 删除记录前的密码窗口

我正在使用以下代码从数据库中删除记录

protected void lnkDelete_Click(object sender, EventArgs e)
{
    string id = ((sender as LinkButton).CommandArgument).ToString();
    string constr = ConfigurationManager.ConnectionStrings["..."].ConnectionString;

    using (SqlConnection con = new SqlConnection(constr))
    {
        using (SqlCommand cmd = new SqlCommand())
        {
            cmd.CommandText = "Delete from UploadedFile where FileID=@FileID";
            cmd.Parameters.AddWithValue("@FileID", id);
            cmd.Connection = con;
            con.Open();
            cmd.ExecuteNonQuery();
            con.Close();
        }
    }
    Response.Redirect(Request.Url.AbsoluteUri);
}

“删除链接”按钮将删除记录。我想添加一个弹出窗口，当用户点击删除按钮，并要求他们输入密码，如果密码正确，然后删除发生，否则他们无法删除记录。如何使用JavaScript或代码隐藏来实现这一点？

在asp按钮中添加属性OnClientClick

ASP代码

<asp:button id="Button1" usesubmitbehavior="true" text="Delete" onclientclick="Confirm()" runat="server" onclick="Button1_Click" />

创建一个运行delete命令的函数

public void DeleteRecord(object _deleteObject){

    string id = ((_deleteObject as LinkButton).CommandArgument).ToString();
    string constr = ConfigurationManager.ConnectionStrings["..."].ConnectionString;

    using (SqlConnection con = new SqlConnection(constr))
    {
        using (SqlCommand cmd = new SqlCommand())
        {
            cmd.CommandText = "Delete from UploadedFile where FileID=@FileID";
            cmd.Parameters.AddWithValue("@FileID", id);
            cmd.Connection = con;
            con.Open();
            cmd.ExecuteNonQuery();
            con.Close();
        }
    }
    Response.Redirect(Request.Url.AbsoluteUri);    
  }

创建全局变量名DeleteObject

 //Global Linkbutton object set here
 private object DeleteObject = null;

将“删除”按钮替换到此位置

protected void lnkDelete_Click(object sender, EventArgs e)
{
   this.DeleteObject = sender;
   Auth.style.remove("visibility");       
}

您是否有可能在客户端代码上使用JQuery.UI？您可以创建一个带有用户名和密码框的自定义对话框。@Mmcgowa3，不，我不使用Jquery.ui可能重复的

public void DeleteRecord(object _deleteObject){

    string id = ((_deleteObject as LinkButton).CommandArgument).ToString();
    string constr = ConfigurationManager.ConnectionStrings["..."].ConnectionString;

    using (SqlConnection con = new SqlConnection(constr))
    {
        using (SqlCommand cmd = new SqlCommand())
        {
            cmd.CommandText = "Delete from UploadedFile where FileID=@FileID";
            cmd.Parameters.AddWithValue("@FileID", id);
            cmd.Connection = con;
            con.Open();
            cmd.ExecuteNonQuery();
            con.Close();
        }
    }
    Response.Redirect(Request.Url.AbsoluteUri);    
  }

 //Global Linkbutton object set here
 private object DeleteObject = null;

protected void lnkDelete_Click(object sender, EventArgs e)
{
   this.DeleteObject = sender;
   Auth.style.remove("visibility");       
}
