I'm using a datagrid with the edit feature. I have an Update functions which gets called when the user clicks update. It looks something like this:
public void UpdateRow(Object objSource, DataGridCommandEventArgs objArgs)
{
}
I can query the objArgs to get the current values of the controls in the datagrid row. Is there a way to get the original values before the user made changes? I need these to identify the record which they're updating.

I have a datagrid which displays some data which works OK. There are two things I am struggling with however.
1) One of the columns contains a path to an image and another contains a hyperlink. I want to display the image pointed to in the database as the actual column and have the image as a hyperlink to the address pointed at from the other column. How can I do this? I looked at Template Columns but I couldn't see how this would work.
2) I want to rotate the grid 90 degrees so I get the columns on the y axis and the data on the x axis. How is this done?
Cheers
James

Hi James,
Try this code to address problem 1.
<ItemTemplate>
<a href="<%# DataBinder.Eval(Container.DataItem, "hyperlink") %>"><img src="<%# DataBinder.Eval(Container.DataItem,"image_file") %>" border="0" /></a>
</ItemTemplate>

I am running a local server for my Web application and stepping through the debugger is impossibly slow (several minutes in fact). The system resources are clear and the application has been working fine until an abrupt and sudden slow down. Database connections are also clear and closed explicitly.

I've had this very same problem only my web server was on another machine. I gave up after a while and just installed iis on my dev machine. This doesn't help you much though...
Anyone got an idea?

Jeremy hit the nail on the head with the links to MSDN on cache control Lauren, however I checked prices for you from South Africa (Cape Town area) to New York City (LaGuardia airport) round trip for a week and the cheapest I could come up with is $2,957.88 (airfare alone). I think it's within your financially best interests to read the MSDN articles.

I try to use Response.IsClientConneted, Session_OnEnd, But seemed it did not work.
does anyone has such experience to solve this problem?
|
|
|
|

I just created a test ASP page and Simply put in:
<code>
<%
Response.Write(Response.IsClientConnected)
%>
</code>
Which returned True, which it should, how are you trying to use it?

I'm trying to make dynamic pages containing database data. My system is a WindowsXP. The database is a MS ACCESS 97 database and it's located on another computer in the network. I made the DSN targeting that database on the network. I cannot move the database on the server cause it's vital that it stays there. I exported the asp file on the database computer and I copied it on the xp server. When I load the asp file I get this error:
HTTP 500.100 - Internal Server Error - ASP error
Internet Information Services
Error Type:
Microsoft OLE DB Provider for ODBC Drivers (0x80004005)
[Microsoft][ODBC Microsoft Access Driver] '(unknown)' is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides.
Why? Can anyone help me with the procedures for connecting to an extern database ?
Thank you !

You need to make sure you are creating a SYSTEM DSN when using ASP, not a USER DSN. Also, your ConnectionString may be referencing either the application path or local path to the DSN and you need to make sure you are targeting the network path instead.

I still do not know where should I put this code. In the head of each file or in global.asa file?
Did anyone ever use it?

Could you explain a little more about what you are trying to do?

I want to write a chat room. When I control the people in a chat room, I should know who will be out of this room. So If one client close its window, it will be out. I want the server to detect it and delete it from a table in database. From book I knew that it can be detected by using response.IsClientConnecte. But I put it in the head of the file and found it did not work. I also want to use Session_OnEnd to control it, but it din't work too.
That is my problem.

I have never used that, however you may consider using a cookie instead. From how I see things( which is sometimes abit skewed ) Response.IsClientConnected would do little value becuase in order for you to use the Response object the *connected* client will essentially need to postback to the server; this is a server-side object.

What I worry about is that how to let server to know the client is off
I do not think cookie can do it.
|
|

|

You could use a timer in javascript, having the client postback to the server once the specified time is up and then delete the user then, there are a lot of possiblities.

I haven't used ASP.NET yet, but I'm assuming it'll be similar to ASP...
Yes, use the Global.aspx file (in ASP it's global.asa), but make sure you have your site as a registered IIS application or else it won't work. It will be called when the application is started the first time.
Use either the Application or Session object to store a variable and value. Use the Application object if you each user to share the same variable. Use the Session object if you want each user connected to the app to be able to have their own copy of the variable. These objects also have event procedures to fine-tune what you can do.
For instance, let's say I wanted to store a username for each connected user. My global file could have something like...
<script language="JScript" runat="Server">
function Session_OnStart()
{
Session("user") = String(GetYourValueSomehow());
}
</script>Then, I could refer to it in any ASP page within the application by using...
Session("user")Also, just as an FYI, the Session object relies on cookies. So, do be somewhat weary when using it. The Application ojbect is completely server-side, so no worries there.
