I have aspx page it is working fine except for few things 1) I am tring to run this page on my mobile device. I have dropdown menu in that dropdown menu there are list of file names with .text user will select the file from the list and once the file is selected I have a textbox in which user will scan a part number into that textbox if it is right part number in database it will show in other textbox the part number and how much quantity. This will go in the text file which user has selected from the drop down menu. so for example user scanned A-1234 if it is in database it will show in textbox which i named txtContent texbox scanned part number and quantity. What I want to have happen is that I want to be able to see what user scanned in the textbox named txtContent so that user can know what he scanned and at the same time this info will go into the file selected by user from dropdown list what is working fine is that it is going into the file if i refresh the page myself but it is now showing up int the txtContent textbox and other thing not working is that When i selected file from dropdown menu lets say i open my page and i selected aaa.txt from the dropdown menu it is fine but then if i reselected same file again while i m on the same page it is not updating the page i want it to be able to update it again even i m on same page and i have same file selected. thanks if you are confused with question please ask me. thanks again.
