Hello, First of all, you need to set the DataSource and DataMember for the BindingSource. Then you can use set the desired bindingSource.ColumnName in the Text property under DataBindings() in the Properties Windows(Located at the top on the window) of the TextBox. In the MoveNext and MovePrevious buttons, you can simply define the following code: BindingSource1.MovePrevious() or BindingSource1.MoveNext() For more information, you can visit the given link: http://www.codeproject.com/KB/grid/BindSourceBindingNavCS.aspx[^] I hope this will help.
