I'm trying to add the content of a user control dynamically at run time,
dependent upon some request attribute.
My user control is a simple tell-tall so I'm sure that's not spoiling
anything.
<%@ Control Language="C#" AutoEventWireup ="true"
CodeBehind="cpS tatus.ascx.cs" Inherits="uc.cp Status" %>
<p>status indicator for special users</p>
In my master page I have this...
<%@ Master Language="C#" AutoEventWireup ="true" CodeBehind="pla in.master.cs"
Inherits="mp.pl ain" %>
<asp:ContentPla ceHolder ID="FirstSideBa rContainer" runat="server">
<!-- side bar may be empty -->
</asp:ContentPlac eHolder>
and in the master page's code behind I have this...
protected void Page_Load(objec t sender, EventArgs e)
{
if (true == true)
{
ContentPlaceHol der ph1;
uc.cpStatus uc1;
ph1 = (ContentPlaceHo lder)FindContro l("FirstSideBar Container");
uc1 = new uc.cpStatus();
ph1.Controls.Ad d(uc1);
}
}
I can step through and debug and every line gets executed without error.
When ph1 is initialized its value is null. When it's assigned the value of
the ContentPlaceHol der contol found by name it has a control count of 1
(that must be the HTML comment asa text node). After the
ph1.Controls.Ad d(uc1) statemment it has a control count of 2, so my user
control would seem to have been added successfully but nothing (other than
the original comment) appears in my placeholder in my page.
What am I doing wrong? 2 1221
It looks like you are finding the container correctly, but the norm for
loading ASCX controls is like so:
Control uc1= LoadControl("UC 1.ascx");
The rest of your code should work fine with this. There are some ways around
doing it this way, but it requires writing a lot of plumbing already in the
..NET libraries.

Hi All
I have been trying to add a control to the header cell of
a datagrid on my ASP.NET page. These controls are defined
in the HTML as ASP.NET web controls.
They are being added into the header of the datagrid in
the "ItemDataBound" method of the grid. However, once,
they are added in the grid, i seem to lose the event
handler for the same control. Is there anyone who has
tried this before and knows why this is hapenning ??

Does anyone know of an issue with a control's viewstate not persisting when dynamically adding custom controls to a web form using AddAt?
If a control is added to an HTML form directly using the HtmlForm's AddAt method (per the below code segment), then LoadViewState is never fired for the control, even if SaveViewState, which is fired, saves to the control's ViewState. However, if Add is used instead of AddAt, LoadViewState is called...

Here's one that should probably have the sub-heading "I'm sure I asked this
once before, but ...".
Two users are both looking at the same data, from a database. One user
changes the data and commits it. How does the other user get the updated
view without polling for changes? Is there some sort of callback mechanism
that can be set up on the dataset or connection?

I dynamically create buttons and associate them with an event using

I want all the button events to fire at one time, when the page is posted,
instead of when each button is clicked.
How I stop the buttons from posting back when they are clicked?

I recently got an error and I don't know how to fix it:
Error 1 'System.Data.DataColumn' does not contain a definition for

I am note sure what to do because all propertiers work, except the
System.Data.DataColumn..
I didn't write any code by hand and used the visual studio to set the

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
