OnRowUpdating 事件和 TextBox_TextChanged 事件未触发

Question

我用一个链接按钮显示网格，如果我点击它，它将显示一个像对话框（弹出窗口）一样的 GridView。那个网格是，

<asp:GridView ID="HistoryGrid" runat="server" AutoGenerateColumns="false" AllowSorting="True"
        CellPadding="4" ForeColor="Black" AllowPaging="True" Font-Size="9pt" BackColor="White"
        BorderColor="#DEDFDE" Width="100%" BorderWidth="1px" GridLines="Vertical" PageSize="10" 
        OnRowEditing="HistoryGrid_RowEditing" OnRowCancelingEdit="HistoryGrid_RowCancelingEdit" OnRowUpdating="HistoryGrid_RowUpdating"
        OnRowUpdated="HistoryGrid_RowUpdated" OnRowDataBound="HistoryGrid_RowDataBound" >

HistoryGrid 有一个 Column 包含 TextBox。

<Columns>
        <asp:TemplateField><EditItemTemplate>
                <asp:TextBox ID="DateTxt" CssClass="datepick" runat="server" AutoPostBack="true" OnTextChanged="DateTxt_TextChanged" Font-Size="8.3pt" ></asp:TextBox>
                </EditItemTemplate></asp:TemplateField>

现在的问题是 TextBox_TextChanged 事件和 HistoryGrid_RowUpdating 事件没有触发。

代码背后

protected void DateTxt_TextChanged(object sender, EventArgs e)
{
 //code
}

protected void HistoryGrid_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
 //code
}

使用ItemTemplate 而不是EditItemTemplate：

<asp:TemplateField>
    <ItemTemplate>
      <asp:TextBox ID="DateTxt" CssClass="datepick" runat="server" AutoPostBack="true" OnTextChanged="DateTxt_TextChanged" Font-Size="8.3pt" ></asp:TextBox>
    </ItemTemplate>
</asp:TemplateField>
