namespace Cte_Net.Templates
{

public class TextboxTemplate: System.Web.UI.ITemplate
{
private string columnName = null;
private string controlName = null;

public TextboxTemplate(string newColumnName)
{
columnName = newColumnName;
}

public TextboxTemplate(string newControlName, string newColumnName)
{
columnName = newColumnName;
controlName = newControlName;
}

public void InstantiateIn(System.Web.UI.Control container)
{
System.Web.UI.WebControls.TextBox label = new
System.Web.UI.WebControls.TextBox();
label.DataBinding += new EventHandler(this.BindLabel);

container.Controls.Add(label);
}

public void BindLabel(Object sender, EventArgs e)
{
System.Web.UI.WebControls.TextBox label =
(System.Web.UI.WebControls.TextBox)sender;
System.Web.UI.WebControls.DataGridItem container =
(System.Web.UI.WebControls.DataGridItem)label.NamingContainer;

label.Text = ((System.Data.DataRowView)container.DataItem)[columnName].ToString().Trim();
