Forms Data Controls :: Gridview And Deleting / Editing Files In Virtual Directory?
Feb 26, 2010
COMPLETE NOOB, dont know anything.. I have a Virtual directory ~/ClubInfoFiles that i upload some files too using a uploader i made. I might want to change the uploader i made to be able to change to a subdirectory or something so i can upload all files into one folder but different subdirectorys. the uploader i would like to be able to have a dropdown menu of all the subdirectorys within "ClubInfoFiles" say i has subfolders : Minutes, Flight Plans, Maintence Records, etc... but i would also like a field to where i can create a new subdirectory and have it automaticly update the dropdown. i want to list those files in gridview and have a link to dowload/open and dellete the files. i have found some code that gets close but it uses Auto Generate columns. really i dont need all that jazz, just the Name, File extention, and hyperlink the file for download/view. i would like to be able to delete and possible upload using the gridview... is this to much for a noob?
my users haves different permission: some users can delete, and some users can editing in a gridview how can i allow this at specified users? and hidden the button ho allow the delelte or update record?
I have a GridView in an update panel that is bound (in code-behind) to a business layer object. The first time this page is accessed, Editing, Deleting, Updating, etc. work fine. However, if I click my browser's refresh button, the functionality of the edit, delete, etc link buttons is gone. They do nothing.
I'm trying to create a nested gridview, but I'm stuck at the editing/deleting part of the nested gridview. (Below is my code).The nested gridviews are filling out nice, I've set the DeleteParameter in the SQLDataSource, but I'm still getting this error when trying to delete a criteria: 'The Gridview 'gvCriteria' fired event RowDeleting which wasn't handled.'I've tried to create a method 'gvCriteria_RowDeleting', but that didn't seem to work out.Someone who can give me a piece of advice? Would it be possible to fill the gridview without using gvDomain_rowDataBound? Dries
I have a small website with a database. Just two tables for personaldata and for files belongs to the personal data.
This files are stored on HD. My problem is to delete this file by clicking on delete button within gridview. At the moment only the record is deleting but not the file which belongs to this record.
That is my Gridview:
[Code]....
and that is my codebehind file:
[Code]....
and see the screenshot. (how it looks like)
i get allready help here to create the right codebehind file for that.
i have tried that this way:
[Code]....
But i think instead of txtFile.Text the filename of thefile should be readed out of the database on this place or Im wrong?
I am learning how to use repeater. I added two links to my repeater, a delete and an edit link. However, when I click either delete or edit link, they both take me to same method. How do I add the link such that when I click on edit, it take me to an edit method and delete takes me to a delete method. Below is a sample code.
Also, how do I delete a single row in a repeated. For example, I have a simple form that display an item description and a quantity. There are six item display on the form, but I wish to delete the third item. How can I pass in an id that will delete the third item rather than delete everything (i.e where item_id = 3)
I have static content like html,css javascript stored in DB. when a user requests for these i create a temp file in virtual directory and return the url. My web app is hosted on a IIS server. On some systems on creation of a file my IIS Application pool crashes and restarts. If i disable file-monitoring though the problem is resolved, but i dont have this luxury when i am deplying at the client end. Is there any way by which i can avoid app pool crash during file creation? If not is there any way by which i can serve static content like html, css, images, xml and js without creating temp files. I would need a generalized way of handling all these data types.
Using vb.net/asp.net 2005.I have an inner gridview.The outer gridview is "Authors" and in the inner gridview (GridView1 below) I have to set it up so that the user cannot delete the last book from the inner grid, if they try to delete the last book from that inner grid then I want to show the exception message below.
So I am checking the GridViewRows1.Rows.Count which works great when I have one record (one book) to start with. The problem is when I have 2 books (for example). I am writing out the test statement below and the RowCount is always 2 each time, never decremented, even after I rebind.Editing this now: i realize that my initial logic is faulty because when I rebind my inner gridview I am not specifying which inner gridview so the result is that only the last inner gridview is being re-bound, so I think that I need to get the selected inner gridview and then refresh that...
I have a WCF service in a virtual directory that is called in the code behind of a page that is in the parent directory, when i debug the code i can see the wcf service is being called, however when the service calls Membership.GetUser() it alway returns null. The user has already logged in to the asp.net site. When i call the service via jquery it does pick up the correct user, but i need to be able to call it via the code behind as well. I am developing in .Net 3.5 how i can make the Wcf pick up the logged in user?
I made a web form on a development website of mine (we'll call it dev.somewhere.com) and tried to publish it out to the web (we'll call it [URL]) in a subfolder. I named it default.aspx like I was supposed to and it worked flawlessly on the dev site. When I published it out the web, I wound up getting the following error when trying to get to the subfolder: [URL] Directory Listing Denied
This Virtual Directory does not allow contents to be listed. Confused and flustered, I tried to go to [URL], but I wound up with some error that won't tell me the problem. Instead it tells me to change the my web.config to read <customErrors mode="Off"/>.
As virutal directory points to physical path of the application, so if the IIS root directory is C:inetpubwwwroot and the application is stored at D:websites, than we need to create a virtual directory but if the application content is placed at C:inetpubwwwroot, then why still need to create virtual directory.
I am using VS2005 and SQL Server 2005. The problem I am having is when I call my SQLDataSource to delete rows the delete is firing twice. The trace and debugging show the code executing once. In fact right after the delete, the table only shows one delete, but right after the command function is exited the 2nd row is deleted. Also, I have tested the stored procedure to make sure it only deletes 1 one and then resequences the records.Show below are excerpts from my .aspx and code behind files.
I've got a GridView that's databound to a DataTable that I have stored in Session. I want to be able to add a LinkButton into this gridview so I can delete rows from the DataTable, however, I need to reference the rows in the datatable somehow.
I figured the simplest was
[Code]....
but the problem is, I need to somehow cross-reference the particular row I want deleted.
Would like to know how can I delete all the session state data (Empty Cart) and deleting a single row from the gridview while still in session state. (Remove Item).
I have a gridview that shows all data from a table. DataNames includes KeyId, which is a Primary Key.Yet when I try to delete a record, nothing happens, the page appears to performa refresh but the record is still there.Edit does not work either. I used the wizard to build all of the queries, they look okay. But I cannot figure out why they are not working.
m using gridview to display records from sql server2005. In gridview, I have a field containing checkboxes. Now what i want that the fields against which a user checked in checkboxes that will be deleted by clicking on delete button just like the emails yahoo, gmail etc How can i do so?
wanted to bind all the files of a directory named "ABC" to a data grid and show them in a .aspx file as downloadable contents. When the user clicks a certain file link, here, the download starts immediately.
I have a nested gridview dynamically added. It seems I resolved all issues with the loading this control on a parent page along with other controls and I can trigger the edit of the first level - the master part of the gridview. However, I cannot trigger the edit on a child gridview.
OnRowEditing="grdChildGridEdit_RowEditing"
The master and the child gridviews have objectdatasources in a markup but I have to do the additional data binding after the loading the control on the parent page (see the code below). I'm doing that additional data binding only for the master gridview that is working fine and shows the data for the master and the child gridviews. When I click the Edit button on the master gridview it shows text boxes for the editing but when I click the Edit button on the child gridview it's doing nothing and moreover the editing mode for the master gridview is going back to the initial stage (labels).
I was trying to trigger it throughuse the registering the event:
I have a gridview,sqldatasource and a link button for delete in the sample code below
When Delete is click the confirmation pops up. When I confirm yes, the rowdeleting event doesn't seem to be firing. I addeed a label to see if the event is firing. To avoid runtime errors I added a dummy but actual sql delete command. Once If I get it to work, I want call a stored procedure to delete the row.
My question is
1. Why is the gridview row deleting event not fired.
I modified a GridView control to enable alphabetical paging, and in doing so had to bind the GridView manually in the code behind rather than using the ObjectDataSource I had used originally.
Now my "delete" command in the GridView isn't working. I get that I need to handle this in the code behind now that I'm no longer bound to the ObjectDataSource.
But I'm not sure how to do that in C# and am not finding any examples.
I have a gridview and a SQLDataSource control. In my gridview I have 2 commandfields "Edit" and "Delete"
The "Edit" command field works as expected. Using the "Delete" command field I get the error below.
Server Error in '/DataControls' Application.
The DELETE statement conflicted with the REFERENCE constraint "FK__titleauth__au_id__0CBAE877". The conflict occurred in database "pubs", table "dbo.titleauthor", column 'au_id'. The statement has been terminated.
