In mathematics, a quotient is the result of division. For example, when dividing 6 by 3, the quotient is 2, while 6 is called the dividend, and 3 the divisor. The quotient further is expressed as the number of times the divisor divides into the dividend, e.g. 3 divides 2 times into 6. A quotient can also mean just the integer part of the result of dividing two integers.
Deleting Columns in the DataGrid Control in VB.NET. You can programmatically delete or hide columns in the Windows Forms DataGrid control by using the properties and methods of the GridColumnStylesCollection and DataGridColumnStyle objects (which are members of the DataGridTableStyle class).
In the Delete Hidden (Visible) Rows & Columns dialog box, specify the scope that you want to apply the operation from Look in drop down list. (If you choose In Selected Range, you must select a range that you want to use first.) And then check Columns under Delete type. And select Blank columns from Detailed type.
