What data type is used to store Man_ID value?
If it's string, then try this:

Dim comm As New SqlCommand("Select [Man_ID] from Manager where[Man_Id] = '" & manid.Text & "'", conn)

If it's integer, try this:

VB

Dim comm As New SqlCommand("Select [Man_ID] from Manager where[Man_Id] = " & manid.Text, conn)

**Manoj K Bhoir** · Accepted Answer · 2012-10-22T02:09:00

If Data Type OF Man_Id Column is String then use :

SQL

Dim CommandObject As SQLCommand = New SqlCommand("Select [Man_ID] from Manager where[Man_Id] = '" & manid.Text & "'", SQLConnectionObject)

Or IF Data Type is Numeric Or Int Then Use :

SQL

Dim CommandObject As SQLCommand = New SqlCommand("Select [Man_ID] from Manager where[Man_Id] = '" & Val(manid.Text) & "'", SQLConnectionObject)

I hope it will help you. :)
