Hello,
I want to be able to display a message/messagebox to a user if the user clicks on the upload button without first
putting image/images on the third pane in the three pane ImageUploader.
By the third pane, I mean the pane at the bottom. I am using Custom buttons.
How do I go about doing this. Any help will be greatly appreciated...
Thanks.
MyCarl.

To show the alert just check whether UploadFileCount property has 0 value. Code:if (getImageUploader('ImageUploader1')==0){
alert("Please select at least one file.");
}
However for better usability I recommend you to disable upload button when there are no files selected. You can check this condition in UploadFileCountChange event handler: Code:function ImageUploader_UploadFileCountChange() {
document.getElementById("UploadButton").disabled = (getImageUploader('ImageUploader1')==0);
}
iu.addEventListener("UploadFileCountChange", "ImageUploader_UploadFileCountChange");

Hello Fedor, In addition to your suggestion, I did the following and it worked great...... Code:var value = getImageUploader("ImageUploaderID").getUploadFileCount();
if (value == 0){
alert("Please select at least one file.");
}
Once again, thanks for your suggestions and help. Regards, MyCarl. Edited by user Monday, February 18, 2008 5:07:01 PM(UTC)
