Hi,

Is is possible to raise a custom validator when uploading a media?

I have this image resizer datatype that I got from daniel. I'm customizing it to raise an error when the image size exceeds 120kb. How can I do that?

Here's my code

 
 
internal bool validateFileSizePath(string origFile)
{
 
 
try
{
 
 
HttpServerUtility map = HttpContext.Current.Server;
 
 
string path = map.MapPath(origFile);
System.IO.
 
FileInfo info = new System.IO.FileInfo(path);
 
 
if (info.Length <= 120000)
{
 
 
return true;
}
 
 
else
{
_customValidator.ControlToValidate = _imageResizerImage.ImageUrl;
_customValidator.Validate();
_customValidator.ErrorMessage = 
 
"Invalid image size. Maximum image size should be 120kb";
 
 
return false;
}
}
 
 
catch (Exception ex)
{
_customValidator.ControlToValidate = _imageResizerImage.ImageUrl;
_customValidator.Validate();
_customValidator.ErrorMessage = 
 
"Invalid image size. Maximum image size should be 120kb. " + ex;
 
 
return false;
}
 
}

and then I call it in 

private
 
 
 void DataEditorControl_OnSave(EventArgs e)
{
 
 
var prevalueEditor = (ImageResizerPrevalueEditor)PrevalueEditor;
 
 
 
if (_imageResizerDataEditor.validateFileSizePath(ImageResizerHelper.GetOriginalUrl(ImageResizerHelper.CurrentNodeId, prevalueEditor)))
{
 
 
var imageUrl = ImageResizerHelper.ResizeImage(ImageResizerHelper.GetOriginalUrl(ImageResizerHelper.CurrentNodeId, prevalueEditor), prevalueEditor.MaxHeight, prevalueEditor.MaxHeight);
_imageResizerDataEditor.ImageUrl = imageUrl;
 
 
base.Data.Value = _imageResizerDataEditor.ImageUrl;
}
}

Am I getting this right?
