未触发OnRowUpdating事件和TextBox_TextChanged事件

Question

I am showing the Grid with one link button, if i click that, it will show a GridView like a dialog(Popup).That Grid is,

<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" >

and the HistoryGrid has one Column contains 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>

Now the Problem Is the TextBox_TextChanged Event and The HistoryGrid_RowUpdating event are not Firing.

Code Behind

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

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

Use ItemTemplate instead of 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>
