Forms Data Controls :: Multiple FileUploads In GridView Doesn't Work?
Aug 24, 2010
Im using File Upload Control in every row of a GridView.... Like tis
Name
UploadFile
textBox FileUpload
TextBox FileUpload
.
.
Submit
On Submit im first uploading all files present in the grid and then saving other values in database....No Problem when uploading Small Set of filesIf i browse more than 10(approx) files(i.e 10 files in 10 rows) and Submit... Internet Explorer-Page Cannot Be displayed Error occurs but no problem when uploading < 10(approx) files....
I have a gridview connected to my objectdatasource, i wrote a class for the database queries.Now when i do an update of record i get the id form the grid, when i click on delete i don't get the id, its 0.Is there an option to set the id? i can't find it in the gridview.
I have a gridview that shows when something is check out. I would like to only show results from todays date and forward. I have done this in Expression Web but when I tried to use the same code in Visual Studios it doesn't work.
I have a GridView; one of the columns displays concatenated records from a tables. to extract the records that are going to be concatenated and put in this column, i have used: FOR XML path('') and it works just fine for displaying those records. the problem now is the whole gridview can not be sorted anymore and gives me a 404, document not found, error whenever i try to click the columns to sort. here is my select statement for my sql datasource select command:
SqlDataSource2.SelectCommand = "Select a1.*, keyword = substring( ( SELECT DISTINCT ', ' + keywordName FROM keywords JOIN key_mm_articles ON key_mm_articles.keywordID = keywords.keywordID WHERE key_mm_articles.articleID = a1.articleID FOR XML path(''), elements ),2,500) FROM articles a1 WHERE title LIKE '" & titles & "' Order By a1.articleID"
I have implemented this plugin by Steve Sanders from 2008. In my solution I have 3 buttons for 3 uploads and this works just fine. But ist not a perfect fit and the question is if thera is a better solution for me?
What I need is : Be able to upload multiple file When the Control Action is triggered It should be possible to work with the files The enduser should be able to cancel a uploaded file(this is not possible with Steves plugin as far as I know)Easy to use with ASP.NET MVC If a post is done to the Control Action and a validation error is thrown back the uploads may not disappear.
I basically have a View Page which allows user input into a Model. The Model consists of a few input boxes and 2 seperate FileUpload controls. Anything input into the text boxes is passed fairly easily to the controller, but the file uploads are really causing me issues. If only one of the FileUploads is used by the client, then the page still posts, but if the client puts files into both of the uploads i get a Http 504 Error:
ReadResponse() failed: The server did not return a response for this request.
As a side note, if I change the FileUpload controls to normal html input controls, the page posts, but Request.Files is always empty.
Here is the code in my view page:
[Code]....
why the FileUpload control causes a 504 error and/or why the standard input control does not pass anything in Request.Files to the controller?
Now, in the code page, I can capture the button click with..
Code: Protected Sub btnUpload_Click(sender As Object, e As System.EventArgs) Handles btnUpload.Click If FileUpload1.HasFile Then Dim name As String = FileUpload1.PostedFile.FileName Dim Justname As String = Path.GetFileName(name)
[Code] .....
All works well... Now, I want to have a few input boxes for uploading different files.
I've got in a gridview with two EditItemTemplate, which are dropdownlist. for the fisrt one I need autopostback because it's used in the second.So to bind the second dropdownlist, I'm useing the GridView1_ItemUpdating, but it doesn't work. It never goes into this funktion and so on updating the column with the second dropdownlist has Null values.What's wrong?That's my code:
i have a gridview that binds data after changes were made (delete,update..) and it's all done with the c# method DataBind() and i don't know why FF shows the changes but in IE8 the grid remains the same and only if i navigate back and refresh, then i see the changes.
I am making checkbox in datagrid, no matter what I try, I cannot get the right result from checkbox. Even I check or not check the checkbox, the result is false. It is like somehow the result is always the default value of the checkbox.
I got a gridview to display the data from the database properly but when I go edit. it give me an error. I searched and change ConflictDetection=CompareAllValues to OverwriteChanges
The error goes away. However the database is still doesn't update. Does anyone had to tweak the gridview function to make it works. Maybe I did something wrong.
by default, my formview loads up to Editmode and it looks like this:
[Code]....
My Page_load looks like this:
[Code]....
Problem is if binding is not ran during postback here, buttons on the ItemInsert mode DO work, but the button on the ItemEdit mode DON'T work. However, if I don't bind the fv1 here during postback, controls will not load on the formview ItemEdit mode and databinding will not occur.
No matter how I set the width in the EmptyDataRowStyle in a GridView, it gets ignored. The width of this construct always takes on the width of the text instead of what is asigned to the width property. This is also true if the property is set as a CSS style width.
If the width is assigned to the GridView construct then the EmptyDataRowStyle will take on that width.
I have done some modification and customization with List.aspx under Dynamic Data.
I must have messed up some controls or events somewhere.
Everything works well except that GridViewPager buttons (|<, <, >, >|) does not bring me to the next or previous page. It stays at the same page.
But if I manually type in the page number into the page number field and press enter, it works brilliantly. The gridview refresh to the correct pageindex.
I've got a problem with DetailsView. I've ot Edit Mode, and when i push "Update" button i would like to switch to "ReadOnly" Mode.sView2.ChangeMode(DetailsViewMode.ReadOnly) doesn't work :/
