AJAX :: Savinf A File Via An Asyncfileupload In A Detailsview In An Updatepanel?
Feb 16, 2010
I want to upload a file INSIDE an updatepanel using the asyncfileupload control.
But in the code below the filename is EMPTY! Why?
Protected Sub dvTicketDetail_ItemUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DetailsViewUpdateEventArgs) Handles dvTicketDetail.ItemUpdating
Dim afupload As AjaxControlToolkit.AsyncFileUpload = CType(dvTicketDetail.FindControl("afuFlyerEdit"), AjaxControlToolkit.AsyncFileUpload)
'only upload physical file if fileupload control is NOT empty
If afupload.FileName <> "" Then
'a new file must be assigned to record
End If
End Sub

I want to update an updatepanel after the user has uploaded a photo via the asynfileupload control.
Below is my current code. I also tried setting updatemode="conditional" to "false" and then in code-behind call upnlPhotos.update, but without luck...
Upload photo: <cc1:AsyncFileUpload ID="afuPhoto" runat="server" /><br />
<asp:UpdatePanel ID="upnlPhotos" runat="server">
<ContentTemplate>
<asp:DataList ID="dlPhotos" DataSourceID="dsPhotos" DataKeyField="id" RepeatColumns="5" RepeatDirection="Horizontal" GridLines="None" runat="server" >
<ItemTemplate>
<img alt="" src='/images/trouwlocatiefotos/thumbs/<%# Eval("locpath")%>' /><br />
</ItemTemplate>
</asp:DataList>
<asp:SqlDataSource ID="dsPhotos" SelectCommand="SELECT id,locationid,locpath from location_photos lp where locationid=@locationid" ConnectionString="<%$ConnectionStrings:conn1 %>" runat="server">
<SelectParameters>
<asp:QueryStringParameter QueryStringField="id" Type="Int32" Name="locationid" />
</SelectParameters>
</asp:SqlDataSource>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="afuPhoto" EventName="UploadedComplete" />
</Triggers>
</asp:UpdatePanel>

I have 2 ddls (cascading that does not use the AJAX cascading ddl) within an updatepanel within an EditTemplate field in a DetailsView. Changing the first ddl causes a full page refresh (this is the problem I am trying to overcome), but changing the second ddl does not. The second ddl is set to autopostback as well because of other logic (if user selects value "Add" a modal pops up to add a new option to the database).
Now the first, does a call out to a class to handle setting the list of values for the second...that is the only difference I can tell between the two, but I wouldn't think that would cause the issue because it is within an updatepanel.
Here's the code:
[Code]....
On Selected Index Change code for each
For the First:
[Code]....
For the Second:
Protected Sub ddlModel_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)
Dim ddlModel As DropDownList = dtlBikes.FindControl("ddlModel")
Dim ddlMfg As DropDownList = dtlBikes.FindControl("ddlMfg")
If ddlModel.SelectedValue = "Add" Then 'Add New Record
txtDDLName.Value = "ddlModel"
txtDtlsViewName.Value = "dtlBikes"
txtItemType.Value = "BikeModel"
txtParentID.Value = ddlMfg.SelectedValue
txtNewItem.Text = ""
txtNewItem.Focus()
lblNewItem.Text = "Enter New Model:"
modInsertItem.Show()
End If
End Sub

I have a GridView and DetailsView in a Master/Detail relationship inside an Update Panel.The GridView displays a set of records, and when a Select button in the GridView is clicked, the detailsview displays the record for edit.Initially the focus is on the GridView, and when the Select button is clicked, I want the focus to be on the first TextBox inside the DetailsView. This happens only when I remove the UpdatePanel from the form. If the Gridview/Detailsview pair is inside an updatepanel, the focus never goes to the DetailsView.How can I make the focus on the DetailsView inside an UpdatePanel

I would like to restrict what they see in the file upload dialog, which is set to "All Files" by default. I understand how to validate that they only uploaded a certain file type, that is not the question here. I would just like to know how to default the file type in the file selection dialog.
Is there any way to change this to "PNG only" or "*.png"?This is using AsyncFileUpload in the ASP.NET AJAX Control Toolkit.

I am using this control to give the user the possibility to upload up to 5 pics. Well, it generally works fine but i started to test it using a folder full of pics. This folder contains more than 900 pics which are named from "DSC_8138.jpg" to "DSC_9255.jpg" (some has been deleted).
When i try to upload the pic "DSC_8138.jpg" it saves the pic "DSC_8168.jpg".
When i try to upload the pic "DSC_8141.jpg" it saves the pic "DSC_8147.jpg".
There is not any clear critieria in this.
I am quite sure that my code in the AsyncFileUpload1_UploadedComplete method cannot cause this problem. Actually, when i try to upload the pic "DSC_8141.jpg" the file name is still "DSC_8141.jpg" even though the pic uploaded is the "DSC_8147.jpg". in any case, the control deals with the uploading process.

I've a Detailsview that contains an updatepanel.A button is pressed within the panel and a window is displayed containing a gridview list.The user selects an item from the list, the window closes and the selected gridview item is placed in "tbResourceID" My problem however comes when the user goes to click insert the validator doesn't fire. I'm guessing this is something to do with the updatepanel isolating the validator.... my code is shown below!

Is there any solution short of posting back, which completely defeats the entire purpose of this control?

I'm developing a website using .NET 3.5 and I'm having problems with the asyncfileupload control.The problem occurs when you upload a file, and then try upload the same file again. On the second upload, none of the clientside nor serverside methods fire. Everything works fine if you upload one file, upload a file with a different name and then upload the first one again.
This is a bit if a pain because on the page i allow the user to delete the uploaded images so i need the functionality to upload a file with the same name as the previous upload.Has anyone else encountered this and are there any work arounds?

I have downloaded a AsyncFileUpload example, I edited the uploadError javascript and now it is working perfectly:
[Code]....
It works perfectly how I wanted it, like this: I upload a file, if it's an Image I get the Lime AsyncFileUpload background, and the file name and size are written under the AsyncFileUpload, if it's not an Image, I get the error label shown, with red AsyncFileUpload background, and if I upload another file, it keeps working the same thing every single time, but only shows the last uploaded image name at the end of an image upload, not all of the images.I tried to merge it with my website, and ended with this code:
[Code]....
but in my website its just working the first time only, then rest times I'm getting the uploadError() function working instantly when I click upload, even if i have selected an image or anything else.

I'm saving a file with the asyncfileupload ajax plugin from the ajax toolkit and when I save it I'm changing the filename (to avoid multiple files with the same name).
After the file is uploaded, the user needs to know what the file has been named so I'm using this javascript code on the onclientuploadcomplete event.
function UploadComplete(sender, args) {
alert(args.get_fileName());
}
This works except it gets the old name, not the new name (which is determined server-side). Is there any way to get it to return the new name rather than the old name? Or any work around to achieve this?
This is my code in the code behind the get the new filename:
string filename = DateTime.Now.ToString("dMyHmsf") + e.filename;
string strPath = MapPath("~/SavedImages/") + filename;
AsyncFileUpload1.SaveAs(strPath);

I am using an AsyncFileUpload control inside a FormView. I only want the file to saved during the FormView's ItemInserting event. In trying to find a way to do this, the only thing I could come up with was to store the AsyncFileUpload control or the PostedFile in a Session variable during the OnUploadedComplete() event and then invoke the SaveAs method in the ItemInserting event. Problem is the SaveAs method is throwing an exception saying "Cannot Access A Closed File". If I invoke SaveAs in the OnUploadedComplete() event, it saves successfully, but I need it to only save when the user submits the form. this error or perhaps a better way to save the file during ItemInserting()?

I'm using the ajax asyncfileupload plugin to upload files to my server and it works fine for the first file upload but if I try to upload another file before refreshing it throws the exception "Unhandled Exception: $common is undefined".
If I add 'location.reload()' to my UploadComplete javascript method it fixes it but obviously this isn't ideal. Does anyone know how to fix this?

I am having a strange issue associated with AsyncFileUpload control. after the upload, I am updating the page by calling__doPostBack function from ClientUploadComplete event handler. it works fine first time, but next time I try to upload the file, it refreshes the page first before uploading, then does the upload and refreshes the page again. not sure why refresh page is being called twice once before the upload and once after the upload. I have a simplified version of this code which has this bug.

AsyncFileUpload control is rendering in this way.
<span
id="Span1"><input
type="hidden"
name="uploadinput$ctl00"
id="uploadinput_ctl00"
/><div
id="uploadinput_ctl01"
name="uploadinput_ctl01"><input
name="uploadinput$ctl02"
type="file"
id="uploadinput_ctl02"
id="uploadinput_ctl02" onkeydown="return false;"
onkeypress="return false;"
onmousedown="return false;"
style="width:
355px;"
/></div></span>
Is there any way to assign styles(like width, position,top etc..) to Input type=file element alone.One way i can see, is using Jquery document.ready eventhandler,
$(function(){
var element = document.getElementById('<%=uploadinput.ClientID%>').lastChild.firstChild;
element.style.width = '150px';
but the problem with that is, i am not able to identify input type = file element after postback in that document.ready eventhandler.please let me know if there is any other way to assign styles to input file element of AsyncFileUpload control with out any issues.
