I have a formview with an edit template which contains a textbox which has "ProductImageUrl" data column bound to it. I want to bind this to a fileupload control instead so that an image can be selected. There is no text field for a fileupload control.
Any ideas?
Thanks
Andrew
Hi, Andrew
Do you want to get the full path of the image? If so, you can use <input id="file1" type="file" ...> then you can get the full path using fil1.value.
Hope this helps.
Is there a way of just getting the file name and not the full path. Can you give me an example of the code behind for using the fil1.value bit.
Thanks
Andrew
Hello
If you want filename, not the full path, you can useFileUpload control and FileUpload1.FileName is that you want.
As to the code, it's very easy.
<%@. Page Language="C#" AutoEventWireup="True" %>
<script runat="server">
void Button1_Click(object Source, EventArgs e)
{if (Text1.Value == "")
{
Span1.InnerHtml = "Error: You must enter a file name." + File1.Value;
return;
}if (File1.PostedFile.ContentLength > 0)
{
try
{
File1.PostedFile.SaveAs("c:\\temp\\" + Text1.Value);
Span1.InnerHtml = "File uploaded successfully to <b>c:\\temp\\" +
Text1.Value + "</b> on the Web server.";
}
catch (Exception exc)
{
Span1.InnerHtml = "Error saving file <b>c:\\temp\\" +
Text1.Value + "</b><br>" + exc.ToString() + ".";
}
}
}
void Click(Object src, EventArgs s)
{
Span1.InnerHtml = File1.Value;
}
</script><html>

<h3>HtmlInputFile Example</h3>
<form id="Form1" enctype="multipart/form-data"
runat="server">
Select File to Upload:
<input id="File1"
type="file" onselect="Click"
runat="server">
<p>
Save as file name (no path):
<input id="Text1"
type="text"
runat="server"></p>
<p>
<span id=Span1
style="font: 8pt verdana;"
runat="server" />
</p>
<p>
<input type=button
id="Button1"
value="Upload"
onserverclick="Button1_Click"
runat="server"></p>
</form>
</body>
</html>
Just click "browser" and then click "upload", the "span" will show the File1.Value.
You can get the file name with the following code
<input type="File" runat="server" ID="InputFile" />
To get the file name use the below line
InputFile.PostedFile.FileName
to get only the filename in a fullpath use
System.IO.Path.GetFileName(fullpath)
HC
The difficult part is that the textbox3 and fileupload controls are within a loginview and a detailsview so doing the findcontrol bit is twisting my melon considerably at the moment.
Any help gratefully received.
Thanks
Andrew
