ทำใน RowDataBound ครับ
Go to : (C#) ASP.NET GridView Control - FindControl
Go to : (C#) ASP.NET SQL Server Edit/Update Record
Code (C#)
//*** Hyperlink ***//
Label hplEdit = (HyperLink)(e.Row.FindControl("hplEdit"));
if (hplEdit != null)
{
hplEdit.Text = "Edit";
hplEdit.NavigateUrl = "WebPage.aspx?CustomerID=" + (string)DataBinder.Eval(e.Row.DataItem, "CustomerID");
}
Code เต็ม ๆ ครับ
Code (C#)
<%@ Page Language="C#" Debug="true" %>
<%@ import Namespace="System.Data" %>
<%@ import Namespace="System.Data.OleDb" %>
<script runat="server">
OleDbConnection objConn;
OleDbCommand objCmd;
void Page_Load(object sender,EventArgs e)
{
String strConnString;
strConnString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" +
Server.MapPath("database/mydatabase.mdb") + ";";
objConn = new OleDbConnection(strConnString);
objConn.Open();
BindData();
}
void BindData()
{
String strSQL;
strSQL = "SELECT * FROM customer";
OleDbDataReader dtReader;
objCmd = new OleDbCommand(strSQL, objConn);
dtReader = objCmd.ExecuteReader();
//*** BindData to GridView ***//
myGridView.DataSource = dtReader;
myGridView.DataBind();
dtReader.Close();
dtReader = null;
}
void Page_UnLoad()
{
objConn.Close();
objConn = null;
}
void myGridView_RowDataBound(Object s, GridViewRowEventArgs e)
{
//*** CustomerID ***//
Label lblCustomerID = (Label)(e.Row.FindControl("lblCustomerID"));
if (lblCustomerID != null)
{

//*** Email ***//

}
//*** Name ***//
Label lblEmail = (Label)(e.Row.FindControl("lblEmail"));
if (lblEmail != null)
{

}
//*** CountryCode ***//
Label lblCountryCode = (Label)(e.Row.FindControl("lblCountryCode"));
if (lblCountryCode != null)
{

}
//*** Budget ***//

if (lblBudget != null)
{
lblBudget.Text = DataBinder.Eval(e.Row.DataItem, "Budget").ToString();
}
//*** Used ***//

{
