In this article I will explain with an example, how to use FileUpload control to accept Excel files in ASP.Net.
HTML Markup
The following HTML Markup consists of:
FileUpload – For uploading file.
The FileUpload control has been set with the following attribute.
accept - This attribute allows user to select only specified type of files from the Choose File dialog box.
Note: Please note accepting all files is default behavior and hence even if the accept attribute is not specified, by default, it will accept all files.
For example, in the following code, the FileUpload control will only allow user to select Excel file i.e. file with extensions xls, xlsx.
<asp:FileUpload runat="server" accept=".xls, .xlsx" />
