10 October, 2008 (14:37) | MOSS - Object Model | By: GVK

Here is the simple custom webpart which inserts items into (Title, Employee Name, Designation) Sharepoint custom list, before executing the webpart first of all you have to create custom list and required fields manually through UI as said below:
Create a custom list, name it as Custom List (you can also choose different name, but make sure to modify the same in the code too) then create columns as mentioned…..
Title [Single line text] (this is by default available, no need of re-creating)
Employee Name [Single line text]
Designation [Single line text]
