I think i'm missing something. What is the proper way to display an html div, for example, if the actual condition is met using Page_Onload + isPostBack + asp:button as a trigger for the event as following:
Page_Load -> Click event fired
Page load - element(a dynamically generted string for multiple table rows in this case)
status hidden
Client click submit button:
Element toggled to visible.
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
nothing yet
}
else
{
suppose to check on client event handle by asp button
}
}
// So here is the event fired by client
protected void imgButSbmt_Click(object sender, ImageClickEventArgs e)
{
initializeReportTable();
}
and suddenly while trying to make sure I am correct with this argument,
I could see that imgButSbmt_Click
is not "hitting" (with break Point attached while in debugging mode).
So first... I could note at this time that it's an unusual behavior (and while I am writing this question supposbly related to all my projects, this one was not firing at all events, so I solved it by deleting the solution file as I was writing this post).
So now, it does work.
BUT... this time (while solution is not yet to be Created) I re-opened my website "project" via File-Open-Website
.
Hit F5
...break Point works fine in red color.. no explanation marks this time. However, all events from the button & Drop down List that are configured to AutoPostBack
protected void DDL_Month(object sender, EventArgs e)
{
initializeReportTable();
}
were not firing. All events except for Page_Load
are firing now. After checking again it does fire but only on the second time!
What is happening here?
I remembered some readings I came across awhile ago that said I should check the autoeventwireup and make sure it is set to true
(it's the default I think).
So these are the page directives:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
Here is an example of a control DropDownList + imgButton within a table:
<td>
<asp:DropDownList ID="DDL_Month" runat="server" AutoPostBack="True" OnSelectedIndexChanged="DDL_Month"></asp:DropDownList>
</td>
<td>
<asp:ImageButton ID="imgButSbmt" ImageUrl="images/sendreq.png"
runat="server" Height="25px" OnClick="imgButSbmt_Click"
style="margin-right: 0px; border-width:" />
</td>
