I have a delete button bellow my gridview and I want a pop up to show when no record is selected and tell the user to first select a record. The button click event would show the pop up, but my gridview data blanks out.
Here is my code:

I have a Gridview that shows my data, I allowed it to have Editing and Sorting. I have achieved refreshing my GV with <META HTTP-EQUIV="Refresh" CONTENT="15">. however, when I Edit and it hits the time to refresh, I loose the Edit mode and starts at the beginning of the grid (I need to find the data again.) Is it possible to still have the refresh (15secs) then when Iam in EditMode, the Refresh stops, then after I have clicked UPDATE. the refresh time starts to count again. (i use VB)

Here's a very strange thing happening and I need to know how to stop it. y ASP.NET web page uses a JSON Ajax call to call a Webmethod that initiates a number of processes. In the IDE when I step my code. Because I'm only testing the first part of the process, there should be no action against the Database until the 2nd phase. I place a breakpoint at the start of the 2nd phase and then I actually stop debugging by pressing the usual square button. I then look in a table on the DB and records have been processed that should not get processed until much further into my code. Stepping line by line until my breakpoint does not call any update functions to the Database (just in-case I'd placed a call somewhere that I didn't mean to). Can someone tell me what's going on in the IDE? At my breakpoint, depending on how long I leave it sitting at the breakpoint before I actually stop the debugging process has a direct impact on the amount of records I see changed/added in the database.

after a DetailsView (DV) 'Insert' (triggered by a DropDownList (DDL)) the DV shows the first record (in the DDL)!Are there VS2008 means to keep / show the just entered data - again ready with the command row "Edit/Delete/New" enabling me to e.g. "Edit" the just entered data?This DDL/DV scenario works just fine but to show my just entered record I have to leave this page and start calling this .aspx page again in order to see the name in the DDL and, hence, in the DV.I.e. I'm looking for a kind of automatic 'postback' bringing my just entered data back

I have made my 1st asp.net web app in vs2010. I run the app and Firefox opens, showing the page. When I close Firefox, the app continues to be (Running) inside VS2010. I think the app should stop running when I close the browser. Is this right? If so, how can I make VS2010 get out of run mode and back to design mode by itself?

A few questions regarding detailsview and gridview:
1) when page load, how can I default the detailsview to show the first record from the gridview? SelectedIndex does not have any effect to my detailsview.
[Code]....
2) how can I select a record in the gridview if my table has 2 key fields using below syntax?

I want to start a new thread to query a database while my web application continues running. I was under the impression that by using threads I can run the querying process independently while the normal web application page cycle carries on, but I could be wrong.
public class DbAsyncQuery
{
Dictionary<string, object> serviceResults = new Dictionary<string, object>();
public void UpdateBillingDB()
{
QueryAllServices();
foreach (KeyValuePair<string, object> p in serviceResults)
{
IEnumerable results = (IEnumerable)p.Value;
IEnumerable<object> sessions = results.Cast<object>();
DbUtil.MakeBillingDBEntry(sessions, p.Key);
}
}
public static string[] servicesToQuery = new string[] // Must go in config file ultimately
{
"xxx.x.xxx.xx"
};
public delegate void Worker();
private Thread worker;
public void InitializeThread(Worker wrk)
{
worker = new Thread(new ThreadStart(wrk));
worker.Start();
}
public void InitializeQuery()
{
Worker worker = QueryAllServices;
InitializeThread(worker);
}
private void QueryAllServices()
{
Dictionary<string, DateTime> lastEntries = DbUtil.GetLastEntries();
foreach (string ip in servicesToQuery)
{
string fullServicePath =
"http://" + ip + ":800/MyWebService.asmx";
//object[] lastEntry = new object[] { lastEntries[ip] };
object[] lastEntry = new object[] { new DateTime(2011, 1, 1, 0, 0, 0) };
object obj = WebServiceHandler.CallWebService
(fullServicePath, "MyWebService", "GetBillingDBEntries", lastEntry);
serviceResults.Add(ip, obj);
}
}
}
It seems to basically stall and wait to finish the query before loading the page (which can be thousands of rows, so it takes awhile). I put this in the following section of Global.asax:
protected void Application_Start(object sender, EventArgs e)
{
DbAsyncQuery query = new DbAsyncQuery();
query.UpdateBillingDB();
}
This is one of my first web pages, and I'm new to threading. I understand there is a difference between creating your own thread and using the ThreadPool. In this method, I am using my own thread, I think. Not sure if that's the best way. The querying process can be completely independent, and its only going to occur on scheduled intervals (every 8 hours or so). The user doesn't need to have up to the minute data, so it can take awhile. I just don't want the site to wait for it to finish, if that's possible.

I've developed a web application to accept video file uploads and then pass them to a backend service on an external server. The application runs without error on the visual studio debugging webserver, but once on a production iis 6 or 7 server, yields a timeout error at about a consistent amount of time into handling a large upload. Specifically, it errors in the middle of transferring the video file to the external server, once the application has successfully received it from the client. I'm aware of several timeouts to be configured related to the problem, and have done so. The application's web config has been tested with one or both of the following settings
<system.web>
<httpRuntime executionTimeout="9999999" maxRequestLength="2048000" />
</system.web>
and
<configuration>
<location path="default.aspx"> (the page at issue that's timing out)
<system.web>
<httpRuntime executionTimeout="9999999" maxRequestLength="2048000" />
</system.web>
</location>
</configuration>
And within the initialization of the webrequest made to the external server to send the video received from the client browser:
HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(url);
httpWebRequest.ContentType = "multipart/form-data; boundary=" + boundary;
httpWebRequest.Method = "POST";
httpWebRequest.Timeout = System.Threading.Timeout.Infinite;
So with the execution time limits on both the webform as a whole and the connection made to the external server, I'm at a loss for what timeout is left unconfigured, or how to determine such, when I continue to get the following error: Unexpected error executing Brightcove Upload:...........................

I have a Panel that is hidden to start with on one of my pages. But once a user posts data to the server, I make the Panel visible to display a success message. I do this by calling Panel1.Visible = true in the function I call for the data submission. I was wondering if there was any way to only display that Panel for a couple seconds by setting a delay or something so it doesnt just stay there until the page is refreshed or they navigate away.The code is below

i have a radio button list that on selecting, queries a table and displays data in a textarea. now i'm trying to enhance my code so that the value of the radio button is displayed within the URL. that way i can send users links to content displayed by the radio selection (i.e. articles).
So far i've been able to place the "Article_PK" within the url successfully when the user makes a selection. now i'm just stuck on how to get my databind working again. so basically, i need to read in the value of the "Article_PK" in the url to display the data within the textarea. need someone with some mad coding skills to save the day!
