how will the menu.ascx recognize the customer id from customer.aspx

You said it's on the query string, so read it off there.

well, the previous reply starts ya off . . . a cliff.

So, here's the paraglide kite so you can fly rather than fall.

This solution presented assumes these things:
0) you are after an 'easy' solution; no bells/whistles
1) The shopkeeper has multiple customers open at the same time (e.g. different tabs in IE7 / FireFox and/or different windows are opened when the shopkeeper clicks a customer's line
2) The customerID (custID) is passed as a query string on the customer.aspx page.
3) web user controls on the customer.aspx page need to know which customer is being viewed
- e.g. so the web user control, like Menu.ascx, can do a call to a database with the custID to figure out which menus to display or which prefs to display

==== Here's the solution:

1) On the customer.aspx Load method, get the custID from the query string and store it in a hidden field on customer.aspx
2) Create a method on each web user-control (ascx) that you call when the customer.aspx page loads, and pass in the custID to that web user control
- I have used some solutions which have a hidden field on each web user control to 'store' the custID; thus avoiding session variables or repeated calls on page.IsPostBack to 'reset' the custID on each web user control.

If this doesn't help, then hire a consultant.

You could try prayer.

Why would you ask how to do something, when you obviously already know what the tools are for doing it, but don't want to use them ?

Hi,
I got answer for this solution

I changed
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

to

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
in design page
Then i used follwing css

/* Div container to wrap the datagrid */
div#div-datagrid {
width: 420px;
height: 200px;
overflow: auto;
scrollbar-base-color:#ffeaff;
}

/* Locks the left column */
td.locked, th.locked {
font-size: 14px;
font-weight: bold;
text-align: center;
background-color: navy;
color: white;
border-right: 1px solid silver;
position:relative;
cursor: default;
left: expression(document.getElementById("div-datagrid").scrollLeft-2); /*IE5+ only*/
}

/* Locks table header */
th {
font-size: 14px;
font-weight: bold;
text-align: center;
background-color: navy;
color: white;
border-right: 1px solid silver;
position:relative;
cursor: default;
top: expression(document.getElementById("div-datagrid").scrollTop-2); /*IE5+ only*/
z-index: 10;
}

/* Keeps the header as the top most item. Important for top left item*/
th.locked {z-index: 99;}

/* DataGrid Item and AlternatingItem Style*/
.GridRow {font-size: 10pt; color: black; font-family: Arial; background-color:#ffffff; height:35px;}
.GridAltRow {font-size: 10pt; color: black; font-family: Arial; background-color:#eeeeee; height:35px;}

my aspx page is

<div id="div-datagrid">
<asp:GridView ID="gv5" Width="100%" runat="server" BorderStyle="Solid"
BorderColor="Navy" meta:resourcekey="gv5Resource1" UseAccessibleHeader="True">
<HeaderStyle BorderColor="Black" ForeColor="Black" BackColor="LightSkyBlue"
/>

<AlternatingRowStyle BackColor="Transparent" />

</asp:GridView>
</div>

6-Feb-09 15:34

Have you checked to see what the ImageType is ? You really have a column called ImageNumner ? Why are you hard coding the number ?

The image type is a image/pjpeg. I tried this too and it did not work.

Response.ContentType = dr["ImageType"].ToString();
Response.Expires = 0;
Response.Buffer = true;
Response.Clear();
Response.OutputStream.Write((byte[])dr["ViewImage"], 0, Convert.ToInt32(dr["ImageSize"].ToString()));

Response.End();

Wow - that makes sense.

Did you try writing the bytes to the file system and seeing if they are really a jpeg ? Have you tried more than one image from your DB ?

AJAX Timer not firing

I'm trying to get the AJAX timer control to work. There is a very simple example of this found here:

http://www.asp.net/ajax/documentation/live/tutorials/IntroToTimerControl.aspx

I followed the example yet the timer event never fires. What am I missing?
I'm using VS2005.

Christian Graus6-Feb-09 9:46

6-Feb-09 9:46

Your code is broken ? Is there a download with the sample, and if so, have you tried that ?

Why do people need the AJAX library just to put a timer in their pages ?

I do not want to use AJAX. How can a incorperate a timer on a page without AJAX?
Please refer to the link in the orginal question for the sample code.

Christian Graus6-Feb-09 9:52

AJAX is just javascript. AJAX exists without the stupid Microsoft AJAX toolkit. There is only one way to have a timer on a page - with javascript. The AJAX toolkit is just wrapping a very basic web dev task for you.

The ^ in my post is a link. Sorry, I dunno what happened, I just pasted and CP auto formatted, I must have hit space or something, I expected you'd see the URL as well as the ^ for a new window.

The answer is that AJAX solves everything. One day it will discover the body of Jimmy Hoffa. I believe it will be found on an as yet undiscovered computing cloud.

I have generated dynamic database table in
which the colums will vary as per the selection
by the end user. Now, if my table name is car which
i have generated dynamically on the button save click
event it will have its colums like: colour, gears etc.
So can i generate a dynamic form by taking the cars id
and its column name as the textbox controls on the new
form. The new generated form will also have the basic
funtionality of add, edit,delete etc. If my table is car
then to generate dynamically car.aspx form or if table
is computer then
computer.aspx should be generated.
