I have a question regarding my vb.net code. I have a button called 'Add New Item', when the user clicks on that button, the text fields should be clear. I tried this code 'txtAddNewItem.clear() and this code too 'txtAddNewItem.Text = "" ' , but I am getting an error, which reads as follows 'Data type mismatch in criteria expression'. Does anyone know how to fix this issue? Thanks..
