How to upload a file in a specific directory

Hi Everyone,
can anyone please let me know how to upload a file to a specific directory. I am using ASP.NET Fileupload component. I want to allow user to upload files to a directory or a sub directory. Depending upon their choice, they can upload in any folder. How can I trace in my web application that a user is in a particular folder & the document he uploads get uploaded in the correct folder or sub folder??? Thanks.

Actually I want to create FTP like application, where users can make, delete, rename directories & subsequently upload files in any of the directory. Any hint or help will much be appreciated. Thanks.

Consider using a TreeView control to show your directory hierarchy. You could add some buttons to add a child directory to the selected node. And you could have a FileUpload control that will save the uploaded file to the selected directory.

If you modify this a little bit to show files, you could have a button to delete a selected file.

This isn't going to be a simple project, but it shouldn't be too hard either.

Thanks InsertAlias for your reply. I have put a TreeView control to show my main directory structure. I show the files of each directory in a GridView infront of it. However I am unable to understand, where do I put the button which create directory in the selected node and also upload files in it?? Is there a way that I can add a button in TreeView or GridView and put FileUpload as well??

re: How to upload a file in a specific directory

What I would suggest is adding either a CheckBoxField or a TemplateField with a Checkbox in it to your GridView. Then have a button outside the GridView that says something like "Delete All Selected Files" or something like that.

Then loop through the gridview and delete all the files that are checked.

As for the other buttons, I'd keep them outside the gridview/treeview. You can put the button to create a new directory below your treeview or something like that. And keep the FileUpload outside the gridview too.

InsertAlias, As suggested I have put a checkbox inside GridView with delete button outside, to delete all checked entries. But Itis throwing index out of range error..dont know why? unable to delete checked files.

re: How to upload a file in a specific directory

You are probably getting the error because the row.RowIndex is larger than your gvFolderItems.DataKeys.

Before you do the following:
You should check that the row.RowIndex value is within limits.

How do I do that? Can you please give me some hint on the code.thanks.

re: How to upload a file in a specific directory

Just to recap:

You've created a TreeView that shows your file hierarchy on the left side of the page.

When a user clicks on a folder in the TreeView your application displays the files and folders found in that selected folder in a GridView.

Now since you want to let the user add and delete files you've put buttons under the GridView.

To delete files or folders, you have the user place check marks next to the things they want to delete.

When the click the Delete button your code should loop through and delete the files checked.


Your code does not currently do this.
First you should loop through your GridView's rows and check which ones have been selected. If you find a selected item, you should store the path to the selected item in an ArrayList or List(Of String). Then pass this to a new function that deletes the files/folders in that list.

After you have finished this process you should recreate the source for the GridView to display the current contents of the file selected.

re: How to upload a file in a specific directory

Yes right, I have put checkbox in GridView so that they can select files to delete. The DELETE SELECTED FILES button is outside of GridView.

One more thing boss, how should I put a button which adds a sub-folder in a selected folder , basing on the user selection (selection from the treeview)??

Thanks.

re: How to upload a file in a specific directory

You're trying to do too many things at once here. Address one problem and then move to the next or we're going to get confused.

Anyways I'd lay out the screen

Or I'd place the buttons on top of the GridView

sorry about that. Yes I have the exact settings in my page.

re: How to upload a file in a specific directory

This is the screenshot of what i have done so far. But I am still unable to configure the DELETE SELECTED FILES or FOLDERS from my gridview. Please anyone can help here

re: How to upload a file in a specific directory

You need to retrieve the names of the files that are selected in the GridView.

Once you have the names you need to loop through them and delete the files.

After you're finished with that you need to recreate the DataSource for the GridView so that it displays the current files in the direcotry.
