我需要在aspx Webform页面上将数据库中的数据显示到GridView中
[英]I need to Show the data from database into my gridview on aspx webform page
问题描述
I want to fetch the data from the sql server database and show it into the gridview which i have created on my aspx webform page but it's not fetching it instead it's throwing an error that says **A field or property with the name 'Name' was not found on the selected data source. 
我想从sql server数据库中获取数据并将其显示到我在aspx Webform页面上创建的gridview中，但它没有获取它，而是抛出了一个错误，提示“名称或名称为**的字段或属性”在所选数据源上找不到。 ** I already have a data row into my database with values under column name and i have created gridview columns in my code but that doesn't seem to work.Please help me get through with this problem.Below is my whole code: **我已经在数据库中有一个数据行，其中的列名下有值，并且我已经在代码中创建了gridview列，但这似乎不起作用。请帮助我解决这个问题。以下是我的整个代码：
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebApplication5.WebForm1" %> <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div> Welcome To My First Web Form<br /> <h1> Candidate Registration Form</h1> <br /> <br /> Applicant's Name: <asp:TextBox ID="TextBox1" runat="server" CausesValidation="True" EnableViewState="False" ValidateRequestMode="Enabled"></asp:TextBox> <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="TextBox1" ErrorMessage="Please enter Your Name!"

Below is the code for cs file behind: 以下是背后的cs文件的代码：
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Data; using System.Data.SqlClient; namespace WebApplication5 { public partial class WebForm1 : System.Web.UI.Page { SqlConnection con = new SqlConnection(@"Data Source=(LocalDB)\\v11.0;AttachDbFilename=C:\\Users\\admin\\documents\\visual studio 2013\\Projects\\WebApplication5\\WebApplication5\\App_Data\\Candidates.mdf;Integrated Security=True"); public static int count = 0; protected void Page_Load(object sender, EventArgs e) { if (!this.IsPostBack) { gvbind(); //DataTable dt = new DataTable(); //dt.Columns.AddRange(new DataColumn[3] { new DataColumn("Name"), new DataColumn("FatherName"), new DataColumn("E-mail") }); //ViewState["Candidates"] = dt; //GridView1.DataSource = (DataTable)ViewState["Candidates"]; //GridView1.DataBind(); } } protected void gvbind() { con.Open(); SqlCommand cmd = new SqlCommand("Select * from Candidates", con); SqlDataAdapter da = new SqlDataAdapter(cmd); DataSet ds = new DataSet(); da.Fill(ds); GridView1.DataSource = ds; GridView1.DataBind(); con.Close(); } protected void TextBox3_TextChanged(object sender, EventArgs e) { } protected void Button1_Click(object sender, EventArgs e) { count += 1; int rowIndex = 0; con.Open(); SqlCommand cmd = con.CreateCommand(); cmd.CommandType = CommandType.Text; cmd.CommandText = "insert into Candidates values('"+TextBox1.Text+"','"+TextBox2.Text+"','"+TextBox3.Text+"')"; cmd.ExecuteNonQuery(); con.Close(); //if (count > 1) //{ // DataTable dtCurrentTable = (DataTable)ViewState["Candidates"]; // DataRow drCurrentRow = null; // if (dtCurrentTable.Rows.Count > 0) { // //for (int i = 1; i <= dtCurrentTable.Rows.Count; i++) // //{ // drCurrentRow = dtCurrentTable.NewRow(); // int totalrows = dtCurrentTable.Rows.Count; // dtCurrentTable.Rows.Add(drCurrentRow); // dtCurrentTable.Rows[totalrows]["Name"] = TextBox1.Text; // dtCurrentTable.Rows[totalrows]["FatherName"] = TextBox2.Text; // dtCurrentTable.Rows[totalrows]["E-mail"] = TextBox3.Text; // rowIndex++; // //} // ViewState["Candidates"] = dtCurrentTable; // GridView1.DataSource = dtCurrentTable; // GridView1.DataBind(); // TextBox1.Text = string.Empty; // TextBox2.Text = string.Empty; // TextBox3.Text = string.Empty; // } //} //else //{ // DataTable dt = (DataTable)ViewState["Candidates"]; // dt.Rows.Add(TextBox1.Text.Trim(), TextBox2.Text.Trim(), TextBox3.Text.Trim()); // ViewState["Candidates"] = dt; // TextBox1.Text = string.Empty; // TextBox2.Text = string.Empty; // TextBox3.Text = string.Empty; // BindGrid(); //} } protected void GridView1_SelectedIndexChanged(object sender, EventArgs e) { } //protected void BindGrid() //{ // //GridView1.DataSource = (DataTable)ViewState["Candidates"]; // //GridView1.DataBind(); //} } }
Just ignore those commented codes,and that error which i mentioned comes when i debug the code on line Gridview1.DataBind(); 只需忽略那些注释的代码，当我在Gridview1.DataBind();行上调试代码时，就会出现我提到的错误Gridview1.DataBind(); in method gvbind(). 在方法gvbind（）中。
