Sir, I have a question, you said that the viewstate property for the asp.net server controls is internally enabled, so I want to ask that is it true for just textboxes or for all asp.net server controls? Can u just help me with this code because it's not working without using viewstate property
in this code I want to upload a picture using Fileupload control but want to see it before uploading but when i click the button 2 the fileupload field becomes empty and I can't upload the picture after that on clicking button 1. I hope u will understand my question??
Sir, I want to ask that, is the view state property enabled internally for all asp.net server controls or just for textboxes?? I tried a code where i want to upload a picture and want to see that picture before uploading it while it's name is in fileupload's field but when i click the show button before upload button the filename is no more there in the fileupload field & therefore upload button doesn't works.. I want to do this without using viewstate property.. Here is a part of my code
