As you said you are working in MVC. It can be done using Jquery as shown below. //To disable all dropdown $( '#radioButton1' ).click( function () { if ($( this ).is( ':checked' )) { $( "#dropdown1" ).prop( "disabled" , true ); $( "#dropdown2" ).prop( "disabled" , true ); $( "#dropdown3" ).prop( "disabled" , true ); } }); //To re-enable all dropdown $( '#radioButton2' ).click( function () { if ($( this ).is( ':checked' )) { $( "#dropdown1" ).prop( "disabled" , false ); $( "#dropdown2" ).prop( "disabled" , false ); $( "#dropdown3" ).prop( "disabled" , false ); } }); You can also use the else condition for all these radio button click as per your business logic.

I have created a test razor view with enable-disable functionality. You can check and modify as per your need. To learn MVC first you should focus on learning JQuery with simple even like onclick, onchange, etc. @{ Layout = null ; } > html > head > script src = "http://ajax.microsoft.com/ajax/jquery/jquery-1.10.2.js" type = "text/javascript" > script > meta name = "viewport" content = "width=device-width" /> title > EnableDisable title > head > body > div > table > tr > td > h3 style = "text-align:center" > Enable and disable textbox and dropdown on radio button click. h3 > hr /> td > tr > tr > td > input type = "radio" id = "rdoButton1" name = "rdoPriority" /> Low input type = "radio" id = "rdoButton2" name = "rdoPriority" /> Medium input type = "radio" id = "rdoButton3" name = "rdoPriority" /> High td > tr > tr > td > hr /> td > tr > tr > td > label > Low Priority: label > @Html.DropDownList("ddlLowDropDown", new List SelectListItem > { new SelectListItem{ Text = "Option 1" , Value = "1" }, new SelectListItem{ Text = "Option 2" , Value = "2" }, new SelectListItem{ Text = "Option 3" , Value = "3" }, }) label > Reason: label > input type = "text" class = "form-control" id = "txtLow" /> td > tr > tr > td > hr /> label > Medium Priority: label > @Html.DropDownList("ddlMediumDropDown", new List SelectListItem > { new SelectListItem{ Text = "Option 1" , Value = "1" }, new SelectListItem{ Text = "Option 2" , Value = "2" }, new SelectListItem{ Text = "Option 3" , Value = "3" }, }) label > Reason: label > input type = "text" class = "form-control" id = "txtMedium" /> hr /> td > tr > tr > td > label > Low Priority: label > @Html.DropDownList("ddlHighDropDown", new List SelectListItem > { new SelectListItem{ Text = "Option 1" , Value = "1" }, new SelectListItem{ Text = "Option 2" , Value = "2" }, new SelectListItem{ Text = "Option 3" , Value = "3" }, }) label > Reason: label > input type = "text" class = "form-control" id = "txtHigh" /> hr /> td > tr > table > div > script > //To disable all dropdown $("#ddlLowDropDown").prop("disabled", true); $("#txtLow").prop("disabled", true); $("#ddlMediumDropDown").prop("disabled", true); $("#txtMedium").prop("disabled", true); $("#ddlHighDropDown").prop("disabled", true); $("#txtHigh").prop("disabled", true); //Re-enable on radio button click $('#rdoButton1').click(function () { if ($(this).is(':checked')) { $("#ddlLowDropDown").prop("disabled", false); $("#txtLow").prop("disabled", false); //Disable other dropdown and text box $("#ddlMediumDropDown").prop("disabled", true); $("#txtMedium").prop("disabled", true); $("#ddlHighDropDown").prop("disabled", true); $("#txtHigh").prop("disabled", true); } }); $('#rdoButton2').click(function () { if ($(this).is(':checked')) { $("#ddlMediumDropDown").prop("disabled", false); $("#txtMedium").prop("disabled", false); //Disable other dropdown and text box $("#ddlLowDropDown").prop("disabled", true); $("#txtLow").prop("disabled", true); $("#ddlHighDropDown").prop("disabled", true); $("#txtHigh").prop("disabled", true); } }); $('#rdoButton3').click(function () { if ($(this).is(':checked')) { $("#ddlHighDropDown").prop("disabled", false); $("#txtHigh").prop("disabled", false); //Disable other dropdown and text box $("#ddlLowDropDown").prop("disabled", true); $("#txtLow").prop("disabled", true); $("#ddlMediumDropDown").prop("disabled", true); $("#txtMedium").prop("disabled", true); } }); script > body > html > I have attached that test project for your reference also.

In which language you are working - C# or VB.Net? Is it windows or web application? If web based then do you want to enable or disable function using Javascript or JQuery? Please explain and it will be helpful to all those who will want to answer your question. As based on your clarification answer slightly may differ from each other.
