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.
Is it possible to only display the desired file type in the file type dropdownlist in the browser window when we click the browser button of the fileupload control of asp.net? If yes then how?

I am using a fileupload control to display the contents of a text file in a textbox..if i use this
<asp:FileUpload ID="txtBoxInput" runat="server" Text="Browse" />
string FilePath = txtBoxInput.PostedFile.FileName;
it will get only the file name like bala.txt.i need like this D:New Folderala.txt
Instead of fileupload control i have used textbox to get the path like this D:New Folderala.txt
<asp:TextBox ID="txtBoxInput" runat="server" Width="451px"></asp:TextBox>
string FilePath = txtBoxInput.Text;
But i need browse button instead of textbox to get the path..
EDIT:My button click event
protected void buttonDisplay_Click(object sender, EventArgs e)
{
string FilePath = txtBoxInput.PostedFile.FileName;
if (File.Exists(FilePath))
{
StreamReader testTxt = new StreamReader(FilePath);
string allRead = testTxt.ReadToEnd();
testTxt.Close();
}
}
I have a webpage in asp.net 3.5 that uses the FileUpload control. When a user clicks on the "Browse" button (which is part of the control) the control displays a file select popup (dialog box). When the user selects the file which they wish to upload, by default the full path to the file is shown in the textbox (which is also part of the control); however, I wish for it to only display the file name and not the full path.
View 3 Repliesi'm developing an application written in C#, and it uses a FileUpload control but i want to add some lines which the user can delete the file that has uploaded to the server. How can i do that?
View 6 RepliesThe requirement is that the whole original file path be saved to the database; for example: L:folder1folder2xyz.doc. However; the FileName property of the FileUpload control will only give "xyz.doc". We are interested in obtaining the full path only and really not interested in using the control to do any upload.
Is there any way to get the full path? We would like our user to be able to browse to the target file instead typing into a textbox because the folder name could be very long and several levels deep in our organization.
I need to create folder and save in to the documentfor example:Suppose if upload the file that file should be save into as/as1/filename like i want saveas/as1/filename, this name will chnage for different different actions..
