| Name | Description | |
|---|---|---|
| Equals | Determines whether the specified object is equal to the current DataGridViewAdvancedBorderStyle. (Overrides Object.Equals(Object).) |
| GetHashCode | Serves as a hash function for a particular type. (Overrides Object.GetHashCode().) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| ToString | Returns a string that represents the DataGridViewAdvancedBorderStyle. (Overrides Object.ToString().) |
The DataGridView control allows you to fully customize its appearance, including the borders of the cells and headers. The DataGridView has CellBorderStyle, ColumnHeadersBorderStyle, and RowHeadersBorderStyle properties that allow you to set the appearance of the cell border. However, if you need to further customize the borders, the DataGridViewAdvancedBorderStyle class allows you to set the style of the border on the individual sides of the cells. The Left, Right, Top, and Bottom properties of DataGridViewAdvancedBorderStyle represent the left, right, top, and bottom border of a cell, respectively. You can set these properties on the AdvancedCellBorderStyle, AdvancedColumnHeadersBorderStyle, AdvancedRowHeadersBorderStyle properties of the DataGridView to produce various appearances for the borders between the cells.
The following code example adjusts the cell borders of a DataGridView so that a double border separates the interior cells and the top left header cell from the row and column headers. This sample demonstrates how to override the AdjustColumnHeaderBorderStyle, AdjustRowHeaderBorderStyle, and AdjustCellBorderStyle methods, and the AdjustedTopLeftHeaderBorderStyle property. These members use DataGridViewAdvancedBorderStyle objects to modify individual cell borders.
