User has to input a field by selecting a row from a list.
I can show a list in Modal Dialog with "thickbox". something like this.
<%=  Ajax.ActionLink("Please Select From List...", "ShowItemsList", "MyController",ViewData.Model, new AjaxOptions {  InsertionMode = InsertionMode.Replace }, new { @class = "thickbox" })%>
But i do not know what shall i do, after user selecting a row in the list? how can i refresh the parent, without losing user data entered?
