View 1 RepliesWeb Forms :: Can't Find FileUpload Control Inside ListView
Jan 25, 2011I have a Listview that houses a FileUpload control. However, after using findcontrol the next line of code tries to convert the filename into a string and produces the familar error object reference not found.
Note: I have used identical code in a formview and it works fine.
Here's my relevent codebehind:
protected void AccessDataSource1_Inserting(object sender, SqlDataSourceCommandEventArgs e)
{
FileUpload FileUpload1 = (FileUpload)ListView1.FindControl("FileUpload1");
string Fupload = FileUpload1.FileName.ToString();
DateTime DateNow = DateTime.Now;
string DateNowSTR = DateNow.ToString();
string NewImageName = DateNowSTR + Fupload;
FileUpload1.SaveAs(Server.MapPath("~//images//" + NewImageName));
e.Command.Parameters["SponLogo"].Value = NewImageName;

FileUpload In FormView Inside An UpdatePanel
Aug 24, 2010I have an ASP.Net webpage which I intend to use for letting the user(not the real users, but content manager basically) insert and edit the records in a table using a FormView. This FormView is inside an UpdatePanel, as I'm also using cascading dropdownlists to let the user select some values. Now, this FormView also contains 4 FileUpload controls, and as you might know that these fileupload controls require a full postback since most browsers do not let Javascript access the disk. So, this problem would have been solved by doing something like:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<Triggers>
<asp:PostBackTrigger ControlID="InsertButton" />
<asp:PostBackTrigger ControlID="UpdateButton" />
</Triggers>
<ContentTemplate>....</ContentTemplate>
</asp:UpdatePanel>
Edit: Forgot to add that the fileuploading takes place in the OnUpdating and OnInserting events of the SqlDataSource. The Problem: Since the InsertButton and the UpdateButton reside inside the Formview, I cannot directly access their ID's through markup. And MSDN says that: Programmatically adding PostBackTrigger controls is not supported. A workable solution for me was to set the UpdatePanel's PostBackTrigger as the whole FormView itself:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<Triggers>
<asp:PostBackTrigger ControlID="FormView1" />
</Triggers>
<ContentTemplate>....</ContentTemplate>
</asp:UpdatePanel>
But now due to a bit of change in requirements, this solution(if you call it a solution) is not acceptable.
AJAX :: Use A Fileupload Control Inside An Update Panel
Apr 5, 2010Having a bit of trouble here. I know that if you want to use a fileupload control inside an AJAX update panel then you need to create a trigger for the control that performs the uploading postback to the updatepanel, but the problem is, I have an update panel that contains web usercontrols. I therefore can't add a trigger to the control(FileUpload) directly because it exists in the web control.
View 2 RepliesAJAX :: FileUpload Controls Does Not Work Inside An Updatepanel
Feb 26, 2010I use a tabcontrol with 2 tabs. In the second tabpanel as seen in the code I use a Fileuploadcontrol to upload Images from a users computer.
The problem is that I need to surround the tabcontrol with an updatepanel as I dont want a fullpage postback when switching between these 2 tabpanels. In this code I have the tabcontrol inside an updatepanel but the problem is that the Fileupload controls does not seem to work inside an updatepanel.
How will I solve this problem as I dont want a fullpage postback when switching between the tabs ?

FileUpload Control Inside Gridview (ajax Updatepanel)
Mar 11, 2011I've got a fileupload control inside of a gridview so that each row (item from the database) can have an attachment associated with it. I've got a button next to the fileupload control (besides the default browse... button to select the file) to actually take the file and upload it to a file server. This works great if I use this button "Upload". However, underneath my gridview I have another imagebutton that is outside of the gridview, its just sitting on the form / page. The idea of this "Update" button is when end users make changes to the grid I can simply loop through the grid and update the values they have entered to the database. This also works great.
Now here is my issue assume a user has 3 rows in the grid view. On 2 of these rows he decides to add an attachment but he never clicks the "Upload" button he only uses the standard browse button to select the file. Now instead of clicking the "Upload" button that is on the grid view he ends up clicking the "Update" button outside of the grid thinking that it will save his attachments. So I decided to write code to grab the fileupload control from the grid using .FindControls("NameOfFileUploadControl") in my Update button loop where I loop through all the rows. Then I check if myFileUploadControl.HasFile property to see if there exists a file and if there does upload the file then continue with the code.
The issue is when I click this "Update" button .HasFile always returns false even though I can see the text string of the path in the fileuploadcontrol textbox (the standard one next to the browse button). Is it because this goes back to the page load event and checks if it is a post back? What causes this and how can I fix it? Im adding some code because im still confused with this
Protected Sub SaveGrid()
For Each Row As GridViewRow In Me.gvLineItems.Rows
Dim f As FileUpload = CType(Row.FindControl("fuAttachment"), FileUpload)
'todo: this part is not working
If f.FileName.Length > 0 Then 'returns 0 always
'this returns 0.
end if
if f.HasFile() then
'this also returns false
end if
Next
End Sub
This method gets called on a click of a button. The fileupload control is in an of a gridview that is wrapped inside of an UpdatePanel:
<asp:FileUpload Width="90px" Font-Size="xx-small" ID="fuAttachment" runat="server" />

View 1 RepliesFileupload Within Update Panel / Can't Get The FileUpload Working Properly
Jan 15, 2010 Hopefully someone can give me some pointers to get this working properly.
I have a webpage which I would like the ability to upload files to be stored in a database. Here's the layout of the page:
[code]....
The update panel is configured as such:
ChildrenAsTriggers="True" EnableViewState="True" RenderMode="Block" UpdateMode="Always" Visible="True" Runat="Server"
The reason I have the update panel outside the Tabcontainer is so that when switching between tabs, the screen doesn't flicker with refreshes, etc. But as a result, I can't get the FileUpload working properly. The FileUpload1.Filename is blank, so it errors out.
Is there anyway to get this working properly? I've tried the latest AsyncFileupload within the control toolkit, but this caused all kinds of problems with my pages so that's out of the question. I tried an iFrame too, but this also didnt work properly.
Forms Data Controls :: Populating DropDownList Inside A ListView Inside A FormView
Jan 16, 2010I have the following (abbreviated) code:
<asp:FormView ID="FormView1" runat="server" DataKeyNames="ItemID" DataSourceID="LinqDataSource1">
<EditItemTemplate>
<asp:DropDownList ID="ddlCategory" runat="server" SelectedValue='<%# Eval("Category") %>'
DataSource="<%# GetCategories() %>" DataTextField="Text" DataValueField="Value" />
</EditItemTemplate>
<ItemTemplate>
<asp:ListView ID="lvParticipants" runat="server" DataSource='<%# Eval("Participants") %>' >
<InsertItemTemplate>
<asp:DropDownList ID="ddlCountry" runat="server" SelectedValue='<%# Eval("Country") %>'
DataSource="<%# GetCountries() %>" DataTextField="Text" DataValueField="Value" />
</InsertItemTemplate>
</asp:ListView>
<ItemTemplate>
</asp:FormView>
When the FormView is in Edit mode, ddlCategory is populated as expected by calling GetCategories(), which returns a List of categories. However, when the ListView is in Insert mode, ddlCountry is empty. I put a break point in GetCountries(), but it never gets called. If I change the name of the method, I get an error. So it recognizes the method at compile time, but does not call it at run time. I'm guessing this is an embedded binding issue of some kind, but I'm hoping someone can save me a lot of time by pointing out the solution.

Forms Data Controls :: How To Disable Button Inside EditItemTemplate Inside DetailsView
Jan 20, 2011I have a boolean / bit value in the database called "is_paid". Depending on this value I want to Disable a button. (the same would go for example to set a textbox not Visible, but anyway)
What I want is to Disable the button, if my boolean is 1 (true).
First I tried to convert my boolean value to text:
<asp:Button
ID="btnCalculatePayment"
runat="server"
Text="Submit"
onclick="btnCalculatePayment_Click" Enabled='<%#
Convert.ToBoolean(Eval("is_paid")) ? "False" : "True" %>'
/>
But got an error:
CS0030: Cannot convert type 'string' to 'bool'
However, if I use it one a Label it works fine: <asp:Label
ID="lblIsPaid"
runat="server"
Text='<%#
Convert.ToBoolean(Eval("is_paid")) ? "True" : "False" %>'></asp:Label>
So another trial I did was to CAST the data from the database to be the text that I want, like so:
SELECT not_paid = CASE WHEN is_paid = 0 THEN 'True' WHEN is_paid = 1 THEN 'False' END ....
And my code changed to:
<asp:Button
ID="btnCalculatePayment"
runat="server"
Text="Submit"
onclick="btnCalculatePayment_Click" Enabled='<%#
Bind("not_paid") %>'
/>
But got this error:
System.InvalidCastException was unhandled by user code
Message=Specified cast is not valid.
Source=App_Web_absjd3ob
StackTrace:
at ASP.manager_aspx.__DataBinding__control74(Object sender, EventArgs e) in c:Documents and SettingsAdminMy DocumentsVisual Studio 2010ProjectsWebManager.aspx:line 219
at System.Web.UI.Control.OnDataBinding(EventArgs e)
at System.Web.UI.Control.DataBind(Boolean raiseOnDataBinding)
at System.Web.UI.Control.DataBind()
at System.Web.UI.Control.DataBindChildren()
So I wonder, is it possible to change the "Enabled" property based on by boolean value?

Forms Data Controls :: Showing Linq Result Values Inside Dropdownlist Inside Listview
Jun 22, 2010I have a listview that is showing its result by using a linq query. The linq query goes like this.
[Code]....
* db.Varer: Varer is a table that contains basic product information like proudct name, product nr. etc. ** a.fk_kategori_id == CatParamId : I'm just saying limit the result according to the Category ID (a.fk_kategori_id). The category id is coming from a dropdownlist (CatParamID) *** Join: Besides the Varer (Product) table I also have another table, Sizes. This Sizes table contains 6 columns (ID_Sizes (int) primary key and the columns: OneSize, S, M, L, XL, XXL all are bit (true or false)). There is a relationship between Varer table and Sizes table. It says that I can only insert a value into the "fk_sizes_id - column" of varer table if that value already exists as primary key within the Sizes table. **** I'm starting by picking basic product values like productId, ProductName etc from the Varer (a) table ***** Then I'm picking the corresponding Sizes values (onesize, s, m, ...) from the Sizes table. Now within my ListView I'm showing the above result by using Eval, like this.

And this works perfectly, but now comes the thing that is causing me trouble. I have the below drop down list (still within the ListView ItemTemplate):
