I have a grid view that is bound to a table in database table (Events) through an objectdatasource that looks something like this:
EventName | Event Description | Event Type
------------------------------------------
my event |Great |Rock n Roll
the database schema is EventName = nvarchar, Event Description = nvarchar and Event Type = Int
Event type is then determined from retrieving an nvarchar value from an EventType table that corresponds
to the integer value it holds.
On Update of an event the Event Type column in the data grid shows a drop down list bound to another
datasource that populates it with the string representations from the EventType table. I am not sure
how to persist the selected value back to the database for the Events table. I have the sql code but am not
sure how to retreive the drop down lists DataValueField and pass it back as a parameter to the Update method.
Any help would be much appreciated. I can post up the code if needed
Thanks

Just copy the whole folder onto the USB drive. If you have set up the project to load via IIS, you need to make sure you copy to the ISS location to open it, or set that location. If you're just opening a solution that is a web project, you have nothing else to worry about.

How can I clear a dropdownlist selected field without it removing the item out of the list? When I do: DropDownList1.SelectedItem.Text = "" it will clear the selected item out of the display and the list.

No, it will set the text of the selected item to an empty string.
You can't clear the selection of a DropDownList, there is always one item selected. Set the SelectedIndex property to zero if you want to reset it back to have the first item selected.

hello all
i have the following function
get from table 1 result 1 the result is 961 row
{
(for each row above)
get from table 2 result 2 by result 1 the result is 1 row
get from table 3 result 3 by reslut 2 the result is 1 row
}
it run for a while then it gaving me this error
Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.
and this is the first time i get this error
note: i use speical pool for it
can anybody tell me what is wrong
thank you

Don't make queries in a loop like that. Join in the data in the first query, so that you make only one query, not 1923 queries.
The error might come from failing to close the database connections properly. As you are running so many queries, you quickly run out of connections.

I guess you should ask people who know what CSSFriendly is. Do they have a website ?

Hi, thanks for looking
Which of the following state management techniques allow you to track information across multiple Web pages when using multiple front-end Web servers? (Choose all that apply.)
Cookies
Session state
Application state
Hidden fields
Query string
...
Correct answers: Session State and Cookies
My question: Cant Application state be used when using multiple front-end Web servers?
Any comments are welcome
Thanks in advance

The problem with Application state is, it's for the entire app. So if you have more than one user, the information stored is for all users, not just the one you're focused on.
Was cross page postback on the list ? Why can't you pass information between pages by forming the appropriate query strings ?

Complete list of options and explanation:
Control state
Application state
Session state
Cookies
Viewstate
Query strings
Hidden fields
Correct answers: Session and cookies
EXPLANATION:
Session state can be stored in a central state server or in a Microsoft SQL Server database. Therefore, by configuring multiple front-end Web servers to store Session state in a single server, a user can move between Web servers without losing Session state.
Cookies store all information on the client, rather than on the server, placing no server-specific requirements on the Web application.
ViewState, ControlState, and hidden fields can be used only to maintain state for a single ASP.NET form. You cannot use them to track settings across multiple Web pages.
Query strings require adding parameters to every link the user might click on your site. Therefore, it would be very difficult to ensure that every link was dynamically generated to contain state information.

Not to share data between servers. Each server is running a separate instance of the application.

Hi,
I wrote an asp app and when I deploy and run it on the server, it will run up to a point then issue a timeout error along with some Event Viewer messages.
When I run the app from my VS IDE, in Release mode the app runs happily without any errors and using the same exact data parameters and settings.
I know that when running from IDE in Debug mode, the debug=true param is set, but I'm running in release mode and I understand that debug=false in that scenario. But regardless, I set debug=true when deployed and it still errors out.
web.congif has session timeout and httpruntime timeout set to over 20 minutes and I also found a trick here on codeproject top keep the page session alive. My sql calls in the app also have high timeout settings.
Can anyone think of why an asp app would run perfectly through IDE and not in production?
If the errors I got were a bit more verbose I might be able to do something with them, but they are not, just says Timed Out.
Thanks in advance for any help!!

Hi All,
I am hardly few months old in asp.net. My current project requires to list the folders (rootfolder) in a treeview. I am using VS2003 and thats the trouble all about. I guess it is easier in VS2005. I did a lot of research and found various codes from the web, however, when I write soemthing with a "Tree" like "TreeView", "TreeNode", "TreeNodeCollection" etc it displays a wiggly line below it. What is the namespace to be included? what am I missing....Someone please explain all this to me together with the code at the earliest....Any help in this regard is highly appreciated.
Regards,
Rinjin

We have deployed three applications(three different virtual directories) having the following settings for SSO.
Forms Authentication-Settings are similar in all the applications
MachineKey entry is kept similar in all the web.config.
The authentication cookie is not persistent.
SSO works well in IE. When the user opens a new window, it asks for the user to log in. When the user navigates to other sites from the same window, it doesn't ask for log in.
In firefox, even if a new window is opened, it doesn't ask for log in and logging in automatically.
Please help.

OR
on Page load method:
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetAllowResponseInBrowserHistory(false);

I applied
<meta http-equiv="CACHE-CONTROL" content="NO-CACHE"></meta>
in master page
and
in page load in test.aspx.cs page
Response.Cache.SetCacheability(HttpCacheability.NoCache);Response.Cache.SetAllowResponseInBrowserHistory(false);
but still it's going back by browser.
thanks
