I have added dynamically some radio buttons to a jsp page.
Now i need to use the unique id of the selected radio button,pass it to some other servlet to process it?
How can it be done?
Place all of your radio buttons within a form that submits to your servlet. Make sure that each of your radio buttons name attributes is set to the same value. Also set the value attribute of each radio button to its respective id. When your form submits, it will pass the value of the selected radio button to the servlet. You can then retrieve the value using request.getParameter().

I am working on a page that has a Telerik UI for MVC ComboBox. Currently the ComboBox does not keep user input once the datasource has returned any value from the database. Even if you reload the page, the ComboBox will remember the value from the Datasource and delete any user input once the focus is changed to another input field.
I need the ComboBox to keep user input if they do not select a value from the Datasource populated drop-down. Any help would be appreciated.
So I found the answer on the Kendo UI API reference. If you set the .SyncValueAndText(boolean) to false it will allow custom text to stay in the ComboBox. By default this value is set to true which binds the text and value together.
Here is a link to the API Documentation:

I have an interactive grid on parent page and from the parent page the modal dialog page is opened. What is the best way to transfer the grid selected value id to the modal dialog page? Do I set up a global variable?
I figured it out. I added hidden field on the page and stored selected value in there. I added another hidden field on modal dialog page and then set it to the value of the first hidden field. It is easily done on the parent page when specifying which page is to be opened in a modal dialog
(MVC Razor) So on my page I have a Kendo grid which contains a DropDownList within a certain column. Now I don't want to fill data of my dropdownlist from controller (With Viewbag/ViewData) before the page loads because it would slow it down, but instead I'd like to fill the DropDownList data on user click with a call to a controller function, and call the read method only once(on first click). How would I be able to achieve this goal?
Set autoBind property to false. It will cause that dropdown will not be filled by data before user click on it.
After component is initialized dataBound event is started so you can set readonly in it.

I have spring form. And I want to populate the form on clicking the radio button next to Employee listing , so that when clicked it should fill the form with data related to that employee in form fields.
I am trying to design a page that has two radio button options and two text boxes with each radio button. I am validating these text boxes using data annotation validation attribute.
I am using jquery slider.toggle() to display each text boxes according to the radio button clicked. When i submit the page, required field validators of both text boxes are triggered. What I want to do is to disable the first text box validation when the second radio button is clicked.
Is there any method in MVC to disable the validation of text boxes when the radio button associated to it is not selected?
This can be done rather simply front end. The validation which occurs is done based on html5's data attribute. Remove the data attributes from an input element and the validation will cease to function.
