Using Data Sources with the DataGridView Control - How to edit the columns of a DataGridView control
(Page 4 of 5 )
Figure 14-8 shows how to edit the columns of a DataGridView control using the Edit Columns dialog box. From this dialog box, you can remove columns from the grid by selecting the column and clicking the Remove button. You can also change the order of the columns by selecting the column you want to move and clicking the up or down arrow to the right of the list of columns.
Finally, you can use the Add button in this dialog box to add a column to the grid. You might need to do that if you delete a column and then decide you want to include it. You can also use the dialog box that’s displayed when you click the Add button to add unbound columns to the grid. You’ll learn how to do that in the next chapter.
Once you’ve got the right columns displayed in the correct order, you can edit the properties for a column by selecting the column to display its properties in the Bound Column Properties window. When you see the Product Maintenance form in the next figure, for example, you’ll see that I changed the HeaderText property for the ProductCode and UnitPrice columns to provide shorter names for the column headers. In addition, I changed the Width property of each column as appropriate. Finally, I used the DefaultCellStyle property to apply currency formatting to the UnitPrice column.
