So, are you accessing this control, or the drop list in your code behind ? You have not posted that code, that I can see.

Are you trying to make it impossible for people to help you ? How about posting the code you use to access the value, the script for the control, etc. Why are you not using the client ID from the server to access the hidden field, but you do for the drop down list ? Have you inserts js code to make sure the right control is being found and it's value set ?

I really don't understand what you are doing.

Where you actual create the DrodownList list?
Sometimes you are get taking
document.getElementById("DropDownList1")
and some time
document.getElementById('<%=DropDownList1.ClientID %>');
Please be specific what is your actual requirement is. As per my understanding You have a Dropdownlist ( Server Side Control ) you add value in the list from JavaScript. Now you want to access the value from Code behind itself. Correct me if I am wrong.

access your dropdown in javascript
document.getElementById("<%=DropDownList1.ClientID %>").options.add(opt);

This question is Nothing to do with ASP.NET. The best forum is General Database.

I don't think you can restore only one Table from a database. The beast you to generatet the script for the particualr table and run the script in new table. And For restoring the data inside the table you have instert the using script only.
Thanks.

So why did you asked it here?
You cannot restore a single table from the backup. You can:
1. Create a new database and restore entire thing into it. Then copy the needed table from there to actual database.
2. You third party tools that allow you to achieve these things. Probably Hyperbac[^] does that. (Just found it through google. Never even heard of it.).

Which version of VS are you using ? I didn't know there was a dataset visualiser built in to start with.

It comes when you quick watch a DataSet or DataTable. VS will show the data in a grid and it is very handy. However, I rarely use DataSet or DataTables.

Well, I guess it's different to the normal visualisers, that appear in a right click menu. I guess your best bet is a reinstall/repair, if there's a feature that has stopped working.

Is it possible in a GridView to hide the Edit and Delete buttons until a user clicks on the Select button of a row? And to only show the Edit and Delete buttons for the selected row?
|

That is cool, but I'm not using it for that reason, really.
The idea behind the project is a list of messages to be displayed on a crawl running on the bottom of the screen, therefore order is important. I want to force the user to SELECT a row before editing or deleting it because I need to capture the INDEX of the message so I can alter each message's index that comes after.
For example, 5 messages
INDEX
1
2
3
4
5
if I delete 3, 4 would need to become 3 and 5 become 4.
Using C# the only way I found to get that information is by using the SelectedValue property of MyGridView. Unless there's another way...?

I have a webservice that takes a byte[] parameter and writes it out to the filesystem. The byte[] is about 120k in length (on average). The webservice can be hit about 20x per minute (so that puts it at about 2.5mb/min). The system administrator is saying this service is causing bottlenecks and other web services/web apps are also failing as a result. He suggest that i change the code to speed up the webservice because it's using up too much resources.
The code is pretty straight forward. I don't understand how this webservice is breaking the other applications/services. I was under the impression that the resource management (thread managment, memory manamgement) is all done under IIS not in the code behind. If i'm not correct what could i possibly do (either in the web.config or code behind) to prevent this from happening. Someone suggested that i monitor the threads in the webservice but that really doesn't make sense to me. I'm totally confused on this subject.
Thanks,

well it happens sometimes to send lots of data to the webservice and also return a lot. Try to check if you are not sending or receiving any unnecessary data.
Also for your webservice, each time it is called the web server spawns a new thread and runs it. Try not to open any new thread from the web service if not absolutely necessary.
And in IIS host the webservice in a new application pool.
