How many items are there in your drop downlist ?
Even you have 100 or 200 it should not give any problem
Thanks and Regards

The item count in the drop down list is over 16,000... yes i know it is alot

Its waste by loading 16,000 items in the Dropdown list just laod all the contents in the DB abd activate it using the Ajax or atlas to the front end.

Hello All,
I am a newbie to .NET and SQL...have been hiding under the rock of Ph.D. studies...
I have a ASP.NET web page with a GridView control on it and I want to display the total number of records in the whole table. I am a newbie to .NET, Databases, SQL, and ASP.NET.
I've seen this posted elsewhere, however I can't make sense of the answers because they assume familiarity with databases. I don't know my DataSet from my DataView from my elbow. If anyone would be willing to give me a hint, I would be greatly appreciative.
Thanks so much.
Sincerely Yours,

My crystal report viewer control has the toolbar enabled, and I fixed it so the images now display.
When I click the Export or Print buttons, nothing happens. I don't see anywhere to override their function either.
I notice many sample report pages contain a separate Print button which handles this. I'd avoid this if possible.

There is formA.aspx having grid and many controls. Now, there is another requirement that there needs to be another textbox and button on top of the form on the basis of which the formA will be populated. This should be formB.
I dont want to add everything on formA into formB. Just want to call formB from formA without redirecting to another page.
How can I do this without using usercontrol becoz this is just needed once and putting it as a user control will be my last chance.
Can you suggest simple method other than going for MDI?
Thanks

There's no such thing as MDI in ASP.NET. Just add the textbox and button and set their visibility. Or make the user control, it's not hard.

SmtpMail may require a user name and password as well as a valid from recipient. Also, is your local IIS setup as SMTP?

SmtpMail is obsolete in .net 2.0.
Maybe try using the SmtpClient instead. So...
<br />
SmtpClient client = new SmtpClient( "localhost" );<br />
client.Send( message );<br />

i think these modifications will make it work
protected void btnSubmit_Click(object sender, EventArgs e)
{
MailMessage message = new MailMessage();
message.To.Add(new MailAddress(txtTo.Text, "any user Name");
mMail.From = new MailAddress(txtFrom.Text, "any user Name");
message.Subject = txtSubject.Text;
message.Body = txtBody.Text;
try
{
SmtpClient sm = new SmtpClient();
sm.Send(message);
litStatus.Text = "Your email has been sent";
}
catch (Exception ex)
{
litStatus.Text="Error sending email";
}
}
}
in web.config, configure smtp
think this shud work

I have been scouring Google for an answer, and cant seem to get a simple one. I am very familiar with using threadpool.queueuserworkitem with windows forms. I have a clear understanding of using delegate methods when interacting with an object that doesn't necessarily belong to the various threads, say each thread is building a row of a datatable
However, I have been having a hell of a time finding code that will do this for asp.net. does anyone have a working example of a multithreaded web app, or could point me in the right direction?

Use a call back or an asynchronous page. However, be very careful, threading in an ASP.NET application needs a very specific intent and purpose. Normal thread logic does not apply.
In fact, I would recommend against it in 99.99% of cases.

all of my tests have blown up in spectacular fashion, so I am awar eof the dangers 
the page i am writing is running, then getting the html from a particular page perhaps hundreds of times. the idea so far has been to allow me to re-use an exisiting page in our app rather than rewriting the code from it in a new page that would then repeat it.
It works like this:
we have a page that uses a querystring to request information from the db. it has a specific formatting to it. The project i have been assigned is to runa query with specific parameters, and then build a page that is a composite of all the pages that "would" be generated by the query results if they were run individually, have them marginally reformatted to break for each printer page, and then launch the print window via javascript.
this is pretty monumental to begin with, but the way i have built it so far runs the query, then loads the "other" page and scrapes the body of it and adds it to a datatable. This works great, except when i run the full query, it takes 20 minutes to load the page. Obviously, this is unworkable. I would like to launch each item in a thread and as they finish rendering, add them to the datattable, then return the whole thing.
does that sounds like a good candidate?

A query that takes 20 minutes is likely in error.
If you insist on this track then I would suggest you need a temporary storage medium for the results, ala session. Then you can poll the session with either ajax or an asynchronous page to update the data table.
I, however, would rework the query.

the query is actually lightning fast, its building the page after the fact that is taking forever.
However, my boss gave me the best solution:
Let them wait. Apparently this thing will run once a month, so they can just deal with the wait.

rotflmao. Can you generate it offline then? Maybe a Windows service that runs and persists it so that the user can just select already rendered packages?

If i had it my way, it would probably just be a console app that ran once a month and output a big html file, but it isnt up to me, so i guess they get to wait.

I have an asp.net page with a calendar control. When the user selects a date in the calendar i dynamically create a changing number of checkBoxes. In this page i also have a button which is supposed to read the values of the checkBoxes. The problem is that page_load fires before my button's click event, and in the click event handler the checkBoxes don't exist so i can't check their values. I tried to save the checkBoxes info in the Session after the date has changed, but that gives me their original values and not the values the user changed before he clicked the button.
Hope i made myself clear enough and you'll be able to help me.
Thx

Where do you create these checkboxes? on client using JavaScript or on the server?
Can you post some code to make it easier to help?
|
|
|
|
|
I create the checkBoxes on the server, in the SelectionChanged event of the calendar. The processing of the information they hold needs to be done on the server too.
The button is created in design time (not dynamically), but it's not visible at start. It becomes visible in the same SelectionChanged event of the calendar. A click on it should be able to access the values of the dynamically created checkBoxes, but the problem is that when the button click event handler is called, the page doesn't contain the checkBoxes any more.
|
|

|
|
hi
write the code for dynamically creating checkbox in a function
and call this function from both in form load each time and in button click
|
|
|
|
|
The checkBoxes build (amount, values, etc) depends on the selected date in the calendar. I can't build the checkBoxes on page_load because i don't know what is the current date in the calendar (the page_load events occurs before the SelectionChanged of the calendar, so the calendar doesn't hold the pressed date in page_load)
