i have a mssql datagridviewer. i only need when user load the form..they must get empty datagrid...data only show when they search any item or add item....i worked on search and add but i am confused on load event ....please help with code

Usually unless we act on something, nothing happens. I'm guessing that you have already binded the datagridviewer to your dataset, from the VB GUI.
Instead, just place an empty datagridviewer and connect it to your dataset whenever you wish programmatically.
Also, share what you've already done to see your approach because I'm guessing here.
