I have developed one custom form widget with designer for file Upload and submit button controls.
I need to introduce custom property like MinFileSize/MaxFileSize for my widget to restrict the file size range.
I am able to get the properties in my Edit Widget Window but it is not reflacting to the code behing.I need to put the server side validation for the Size but I am not able to get the entered value persist at codebehind.
Here I hv attached some file for referance.
Please help me out on this .
I am going to demonstrate this app to the client to purchase licence version for sitefinity.
