In my case I was forced to use the "Bind" method on mi EditItemTemplate's TextBox because needed the data to be accessible in the NewValues array at the item_Updating event handling. So i figured out as follow:

on my EditItemTemplate :

<EditItemTemplate>
     <asp:TextBox runat="server" Text='<%# Bind("field")%>' ID="TextBox112" OnPreRender="TextBox_PreRender_decode"></asp:TextBox>                                            
</EditItemTemplate> 

then in the code behind :

protected void TextBox_PreRender_decode(object sender, EventArgs e)
{
    TextBox tb = (TextBox)sender;
    tb.Text = WebUtility.HtmlDecode(tb.Text);
}

This solution allowed me to show properly an html-encoded data for all of my TextBoxes and at the same time being able to access this data from the newValues array when the item_Updating event fires.

Bind() is used for Two-Way Data Binding, for this to work you will have to use the RowUpdating event of the gridview.

void GridView_RowUpdating(Object sender, GridViewUpdateEventArgs e)
{
    foreach (DictionaryEntry entry in e.NewValues)
    {
        e.NewValues[entry.Key] = System.Web.HttpUtility.HtmlEncode(entry.Value.ToString());
    }
}
