Asp.net + Previewing An Image Without Saving It Locally?
Nov 15, 2011
I a function belows which is being used to preview an image but that involves saving the image locally in my drive. I am using this feature in an data entry form which means if the user discards the form, I have to delete the image which I feel is not efficient. How can I go about previewing the image and only save it locally if the user saves the form.
Protected Sub save_btn_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btn_Save.Click
