[英]Insert the rating after clicking the submit button using asp.net c#
我正在尝试根据单击提交表单按钮将我的评级表单插入数据库，但出现以下错误。
编译器错误消息：CS0123：“sendbtnSubmit”没有重载匹配委托“System.EventHandler”

cmd.CommandType = CommandType.Text;
cmd.Connection = connection;
cmd.Parameters.AddWithValue("@Name", name.Text);
cmd.Parameters.AddWithValue("@Emailid", email.Text);
cmd.Parameters.AddWithValue("@Category", cate.Text);

我想在使用 asp.net C# 单击提交表单后将评级存储到数据库中。
改变这一行：
protected void sendbtnSubmit(object sender,AjaxControlToolkit.RatingEventArgs e)
到：
protected void sendbtnSubmit(object sender,EventArgs e)
编辑：
对于您在评论中所说的第二个问题，您有两个选择：
1- 在 Rating1_Changed 事件中使用数据库。（不推荐）
2-在sendbtnSubmit事件，而不是使用e.Value.ToString()使用此myabe Rating1.CurrentRating.ToString()
编写您的代码如下：
您没有在代码中使用 AjaxControlToolkit.RatingEventArgs，因此不清楚它的来源。
protected void sendbtnSubmit(object sender,EventArgs e)
{
string connectionString = "Server=KSRSAC-G2G\\SQLEXPRESS;Database=Registration;Uid=sa;Pwd=SA#123;";
using (SqlConnection connection = new SqlConnection(connectionString))
{
SqlCommand cmd = new SqlCommand("INSERT INTO [Registration].[dbo].[FeedBack] (Name,Emailid,Category,Feedback,Area,Rate) VALUES (@Name, @Emailid,@Category,@Feedback,@Area,@Rate)");
cmd.CommandType = CommandType.Text;
cmd.Connection = connection;
cmd.Parameters.AddWithValue("@Name", name.Text);
cmd.Parameters.AddWithValue("@Emailid", email.Text);
cmd.Parameters.AddWithValue("@Category", cate.Text);
cmd.Parameters.AddWithValue("@Feedback", msg.Text);
cmd.Parameters.AddWithValue("@Area", ddlfields.Text);
cmd.Parameters.AddWithValue("@Rate", e.Value.ToString());
connection.Open();
cmd.ExecuteNonQuery();
}
}
protected void Rating1_Changed(object sender, EventArgs e)
{
lbl_point.Text = "You rated " + e.Value.ToString();
}
}
