File Validation

[Berkman]

Hi,

While the user upload files to the server using RadUpload, Is there any mechanism to perform file validation process for a particular file extension alone?

Thankyou,
Berk.

Hi Berkman,

It is possible to perform custom validation for a particular file extension. You can write the necessary code to perform custom validation in the ValidatingFile server-side event. Please have a look into the following C# code which performs a custom validation for ZIP files.

C#:

private void RadUpload1_ValidatingFile(object sender, ValidateFileEventArgs e)
{
    // check only the zip files
    if (e.UploadedFile.GetExtension().ToLower() == ".zip")
    {
        //Your Custom Validation Code

        // zip files must not be validated for file size by the internal validator
        e.SkipInternalValidation = true;
    }
}

Thanks,
Princy.
