Unfortunately, that would give me the entire list of files. The gridview is tied to the specific record on screen and the file(s) are shown in the gridview. I do not want users to have to hunt to find a record to delete. I just want a delete button next to the download button to remove the file.

Did you try to understand what I told you?
The link I gave, was about "How to delete one single instance of file from your machine". You can use it, to delete one file (at a time). It won't give you the list of files, that is the job of Directory.EnumerateFiles(string location)[^] to provide you with the list of files available in a directory.
The button that you're talking about, that has been tied to the delete event. You can write this code in it.
void Button_Click(object sender, EventArgs e) {
string file = "You can pass the location from a parameter.";
File.Delete(file);
}
Once this code would execute, the file at that location (you need to pass the location of the file to delete, so embed the file path somewhere alongwith the button) would be deleted.

That's my problem. I cannot get the path. I have the folder path, I have the file name but putting both together in the delete button is frustrating me.
|
|
|
|

Why is it frustrating at all?
Now this is somewhat stupid for me, concatenating the directory and filename is frustrating. In which sense actually? You're concatenating it to extract the file from the machine, but you're having psychological troubles while concatenating the both while you're about to delete?

It's frustrating because it's not working. I'm very much a novice at this. I've tried several different ways of taking the folder "~/files/" and the file name, tying them together and deleting the file.

First, sorry for being rude.
Secondly, you should try this code then.
File.Delete(Server.MapPath("~/Files/Location.format"));
You can pass the virtual location to your file and it would delete the real file from the machine. The Server.MapPath[^] should be used when working on a web application, on an HTTP server you don't specifically share the actual path to a resource, instead you share the virtual path to the file using a URL and a domain and so on, in such scenarios Server.MapPath() is used to handle the virtual paths and converts it to real path; such as D:\Files\Location.format. You can read the MSDN document I have attached to the answer too.

I've tried multiple ways but I cannot get the filename to come over. I'm thinking this is a lost cause and will be stuck going into the folder and manually deleting the files and the line in the table

I have a page with 6 textbox. I want to fetch data from database ms access but there may be many combination like user fill only one box and fetch or user can fill more than one box and fetch data. there may be many combination.
i have emp_id, from date, to date, expiry date, request number, status.
combination may be user only fill one box i.e emp_id or from date or status etc.
or user can fill emp_id and status and request number and from date etc.
|
|
|
|
|
|
The problem is I am not able to understand whether to check if textbox1.text is not null and textbox2.text is not null then perform this query for every possible combination or what?   
|
|
|
|
|
Firstly, please don't fill you message with emoticons, they add nothing useful.
Secondly, it is just a matter of checking your textboxes in order, and if they contain a value then adding them to your query. So, your final query would be built up something like:
SELECT [record qualifier] WHERE Parameter1=@Value1 AND Parameter2=@Value2 ... "
adding each parameter as appropriate, ensuring you use a proper parameterized query, not a concatenated string.
|
|
|
|
|
So I have to check every possible combinations with textboxes.
|
|
|
|
|
No, you just check each one in order, and if it contains a value then you add the details to your query. After checking all textboxes you will have built a query that contains parameters from only those textboxes that have been filled in.

I have a page with a grid view and it has a link button called Details. When I click on Details it shows the detailed view below panel with all textboxes and dropdowns. I also have a button Export-to-Excel. This button when first loaded will be one. But soon clicked on detailed view it appears twice. wondering where is this coming from. I don't see anything wrong on ASPX page.
Your help is much appreciated.
Thanks
Happy Coding!

How did you make the button?
In Code behind or using the Web form, perhaps Javascript?
Is this a ASP.Net Object Button?
|
|
|
|
|
It is <asp:button>
Your help is much appreciated.
Thanks
Happy Coding!

A cookieless session means that instead of the encrypted session id being passed through a cookie it will be passed in the querystring.
https://msdn.microsoft.com/en-us/library/aa479314.aspx[^]
7 days is a long time for a session to remain active but just set the value you want in web.config for session timeout.
If user closes browser then they're session will be lost since there is no cookie on the machine to send the next time they open the browser.
There are only 10 types of people in the world, those who understand binary and those who don't.
