Dim drop_obj2 As DropDownList = TryCast(LoginView2.FindControl("ddlType"), DropDownList)
drop_obj2.DataValueField = dtEvents.Rows(0)("EventType")

// SelectedIndex
Dim drop_obj As DropDownList = TryCast(LoginView2.FindControl("ddlSize"), DropDownList)
drop_obj.SelectedIndex = dtEvents.Rows(0)("EventEventSize")

Dim drop_obj2 As DropDownList = TryCast(LoginView2.FindControl("ddlType"), DropDownList)
drop_obj2.SelectedIndex = dtEvents.Rows(0)("EventType")

// SelectedValue
Dim drop_obj As DropDownList = TryCast(LoginView2.FindControl("ddlSize"), DropDownList)
drop_obj.SelectedValue = dtEvents.Rows(0)("EventEventSize")

Dim drop_obj2 As DropDownList = TryCast(LoginView2.FindControl("ddlType"), DropDownList)
drop_obj2.SelectedValue = dtEvents.Rows(0)("EventType")
