For Disable and ReadOnly TextBoxes Onchange event will not fire So instead add a  hidden Button and assign a Click event to it and do calculations on itBut here also you will have to make the TextBox ReadOnly instead of Disabled otherwise the value will not be available server sidelthtml xmlns34httpwwww3org1999xhtml34gtlthead id34Head134 runat34server34gt    lttitlegtUntitled Pagelttitlegt    ltscript type34textjavascript34gt        function SetValue             var txt  documentgetElementById34ltTextBox1ClientID gt34            txtvalue  34Hello34            documentgetElementById34ltButton1ClientID gt34click            ltscriptgtltheadgtltbodygt    ltform id34form134 runat34server34gt    ltinput type  34button34 onclick  34SetValue34 value  34Set Value34 gt    ltaspTextBox ID34TextBox134 runat34server
