Yes call your drop-downs method in page load, why do you want to use select changed event? do you want to cascading dropdowns?

put the selectedindexedchanged code in a separate method and call the same method in pageload and selectedindexedchanged. Why you want to call the event in page load any specific scenario let us know

i want that when an employee login ,then base on his last sector record ,sector must be selected auto,and and user can not change it.

1 solution

Keep this event handler as it is.

Now bind the dropdown 'ddlSelectSector' in page load, set its default value just after binding it within same page load and load the 'ddlRollNo' dropdown on its selected value in same page load.

Further 'ddlRollNo' will be always rebound on first dropdown selection change due to the above selectedindex change event handler.

Hope this works for you, please give more details id this does not help you.

sir i have the following scenario, i want that when a user login in base on his last record from employee duty table in ddlsector that sector must be selected and user can not change it

then whats the problem just populate the ddlSector on page load event handler of the page, and set its value within it as well. Then make it read only or disabled and populate the secondary dropdown on its selected value if needed.
