I'm trying to upload a file in VB.NET using an HtmlInputFile, but everytime I upload, the HtmlInputFile's PostedFile is Nothing.
Here is my ASP.NET code:
<form id="Form1" method="post" runat="server" enctype="multipart/form-data">
<asp:DataGrid id="dgTitles" runat="server" OnUpdateCommand="dgUpdate" DataKeyField="ID">
<Columns>
<asp:TemplateColumn HeaderText="Title" >
<ItemTemplate>
<asp:Label ID="lTitle" Runat="server">
<%# DataBinder.Eval(Container, "DataItem.Title" )%>
</asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="tTitle" Runat="server" text='<%# DataBinder.Eval(Container, "DataItem.Title" )%>'>
</asp:TextBox>
</EditItemTemplate>
</asp:TemplateColumn>
<asp:TemplateColumn HeaderText="Image">
<EditItemTemplate>
<input id='fuEditImage' type="file" name="fuEditImage" runat="server" enctype="multipart/form-data" />
</EditItemTemplate>
</asp:TemplateColumn>
<asp:EditCommandColumn UpdateText="Update">
</asp:EditCommandColumn>
</Columns>
</asp:DataGrid>
</form>
Here is my VB.NET code:
Sub dgUpdate(ByVal sender As Object, ByVal e As DataGridCommandEventArgs)
Try
Dim Title = CType(e.Item.FindControl("tTitle"), TextBox).Text
Dim fuUpload As System.Web.UI.HtmlControls.HtmlInputFile = CType(e.Item.FindControl("fuEditImage"), _
System.Web.UI.HtmlControls.HtmlInputFile)
If Not fuUpload.PostedFile Is Nothing Then 'This always = false
If Not fuUpload.PostedFile.FileName = "" Then
UploadImage(fuUpload)
End If
End If
Catch ex As Exception
'Handle Exception here
End Try
End Sub
When I upload a file, fuUpload is not Nothing, but fuUpload.PostedFile is.
The inputted "Title" text is recognized no problem.
I've also tried with FileUpload object and tag, instead of input tag and HtmlInputFile-- same result.
Can anyone tell me what I'm doing wrong? Why is PostedFile always nothing?
Thanks!

Add a blank row in data set and then bind it with grid view. If you want to do it on button click do the same on button clicki.

Hi, I read XML file from web site using with following code;
string Url = "http://www.abc.com/myfile.xml";
WebRequest webRequest = default(WebRequest);
WebResponse webResponse = default(WebResponse);
DataSet ds = new DataSet();
webRequest = WebRequest.Create(Url);
webResponse = webRequest.GetResponse();
Stream responseStream = webResponse.GetResponseStream();
ds.ReadXml(responseStream);
How can I add password protection for read this xml file from URI?
Best Regards...

you are responding the XML through a Handler I think....
If so, just when the request is made, you can place the password to the request header.. .
from the handler, check whether the request header contains the passkey or not.. .

In case of a Http error 500, how to retry the AJAX call one more time before displaying the error to the user
|
|
|
|
|
do that call again.. buddy...
but you need to create a new Object of XMLHttpRequest to make the call again.... .
Just when obj.status == 500 create a new object and call ajaxobj.send(null)... or whatever you need. ![Rose | [Rose]](https://codeproject.freetls.fastly.net/script/Forums/Images/rose.gif)

Hi friends,
I have a datagrid with various radiobuttons binded in it. on clicking the radiobutton im using an to load the related page.
And also im doing the sorting on the data grid on clicking at the header of the grid column.
My problem is once i click on the radio button, i can able to see the page through <iframe>. After that, When i try to sort the grid the values in the grid are sorted out but the page i loaded through the radio click event disappears. The radio button which i clicked alone retains...
again if i click the same radio button or different one the page appears.. 
I need to retain the page as well after sorting.
Kindly help me on this.
Thanks in advance
