In this article I will explain how to bind data (values) to TextBox inside TemplateField column of GridView in ASP.Net using C# and VB.Net.
	
		The TextBoxes will be populated with values from database using the DataBinder Eval function.
	
		 
	
		 
	
		Database
	
		I have made use of the following table Customers with the schema as follows.
	
	
		I have already inserted few records in the table.
	
	
		 
	
		
			Note: You can download the database table SQL by clicking the download link below.
		
	 
	
		 
	
		 
	
		HTML Markup
	
		The HTML Markup consists of an ASP.Net GridView consisting of TextBoxes inside TemplateField column of GridView.
	
		The Text property of the TextBox will be dynamically populated from database using DataBinder Eval function.
	
		
			<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
		
			    <Columns>
		
			        <asp:TemplateField HeaderText="Customer Id" ItemStyle-Width="30">
		
			            <ItemTemplate>
		
			                <asp:TextBox ID="txtCustomerId" runat="server" Text='<%# Eval("CustomerId") %>' />
		
			            </ItemTemplate>
		
			        </asp:TemplateField>
		
			        <asp:TemplateField HeaderText="Name" ItemStyle-Width="150">
		
			            <ItemTemplate>
		
			                <asp:TextBox ID="txtName" runat="server" Text='<%# Eval("Name") %>' />
		
			            </ItemTemplate>
		
			        </asp:TemplateField>
		
			        <asp:TemplateField HeaderText="Country" ItemStyle-Width="150">
		
			            <ItemTemplate>
		
			                <asp:TextBox ID="txtCountry" runat="server" Text='<%# Eval("Country") %>' />
		
			            </ItemTemplate>
		
			        </asp:TemplateField>
		
			    </Columns>
		
			</asp:GridView>
	 
	
		 
	
		 
	
		Namespaces
	
		You will need to import the following namespaces.
	
		C#
	
		
			using System.Data;
		
			using System.Configuration;
		
			using System.Data.SqlClient;
	 
	
		 
	
		VB.Net
	
		
			Imports System.Data
		
			Imports System.Configuration
		
			Imports System.Data.SqlClient
	 
	
		 
	
		 
	
		Binding the GridView
	
		Inside the Page Load event of the page, the GridView is populated with the records of the Customers Table.
	
		C#
	
		
			protected void Page_Load(object sender, EventArgs e)
		
			{
		
			    if (!this.IsPostBack)
		
			    {
		
			        string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
		
			        using (SqlConnection con = new SqlConnection(constr))
		
			        {
		
			            using (SqlCommand cmd = new SqlCommand("SELECT CustomerId, Name, Country FROM Customers"))
		
			            {
		
			                cmd.Connection = con;
		
			                using (SqlDataAdapter sda = new SqlDataAdapter(cmd))
		
			                {
		
			                    DataTable dt = new DataTable();
		
			                    sda.Fill(dt);
		
			                    GridView1.DataSource = dt;
		
			                    GridView1.DataBind();
		
			                }
		
			            }
		
			        }
		
			    }
		
			}
	 
	
		 
	
		VB.Net
	
		
			Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load
		
			    If Not Me.IsPostBack Then
		
			        Dim constr As String = ConfigurationManager.ConnectionStrings("constr").ConnectionString
		
			        Using con As New SqlConnection(constr)
		
			            Using cmd As New SqlCommand("SELECT CustomerId, Name, Country FROM Customers")
		
			                cmd.Connection = con
		
			                Using sda As New SqlDataAdapter(cmd)
		
			                    Dim dt As New DataTable()
		
			                    sda.Fill(dt)
		
			                    GridView1.DataSource = dt
		
			                    GridView1.DataBind()
		
			                End Using
		
			            End Using
		
			        End Using
		
			    End If
		
			End Sub
