Hi Friends,
I hope the below solution helps....
1. Please add the required field validator for the texbox.
2. In Page_Load method, we can add the below statement
Dropdownlist.Attributed.Add
("OnChange","javascript:ValidateOtherCity();")
Add the below javascript function on the aspx page
function ValidateOtherCity()
{
var other = window.document.getElementById
("DropdownlistName");
if(other.value == 'Other')
{
ValidatorEnable(RequiredFieldValidatorName,true);
}
else
{
ValidatorEnable(RequiredFieldValidatorName,false);
}
}
