Hi,

How do I check in the following that an item has actually been selected from radio button list rbWalking? If there has been no selection made, I want to set WalkingParm.Value = DBNull.Value

Dim WalkingParm As SqlParameter = cmd.Parameters.Add("@Walking", SqlDbType.Int, 4) WalkingParm.Direction = ParameterDirection.Input WalkingParm.Value = CInt(rbWalking.SelectedItem.Value)

Thanks,

John

You can check it like this

dim bRadioButtonSelected

if(Request.Form("rbWalking")="") then
    bRadioButtonSelected=false
else
    bRadioButtonSelected=true
end if
