How to Bind the two textbox Values Dynamically in Datagridview using c#?

You can bind any control to the DataBase by creating DataSets or DataView.
First create New DataView.

public void CreateDataView()
       {
       OleDbDataAdapter objda = new OleDbDataAdapter();
       objda.SelectCommand = new OleDbCommand();
       Conn.Open(); //Openning DataBase Connection
       objda.SelectCommand.CommandText = "Select * FROM TableName";
       objda.Fill(objdataset, "TableName");
       dv = new DataView(objdataset.Tables("TableName"));
       }

Call CreateDataView on Form_Load Event.
Then bind your TextBox with DataView

this.TextBox1.DataBindings.Clear();
this.TextBox1.DataBindings.Add("Text", dv, "TableFieldName");
