Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public virtual DataGridViewAdvancedBorderStyle AdjustRowHeaderBorderStyle(
	DataGridViewAdvancedBorderStyle dataGridViewAdvancedBorderStyleInput,
	DataGridViewAdvancedBorderStyle dataGridViewAdvancedBorderStylePlaceholder,
	bool singleVerticalBorderAdded,
	bool singleHorizontalBorderAdded,
	bool isFirstDisplayedRow,
	bool isLastVisibleRow
)

Parameters

dataGridViewAdvancedBorderStyleInput
Type: System.Windows.Forms.DataGridViewAdvancedBorderStyle

A DataGridViewAdvancedBorderStyle that represents the row header border style to modify.

dataGridViewAdvancedBorderStylePlaceholder
Type: System.Windows.Forms.DataGridViewAdvancedBorderStyle

A DataGridViewAdvancedBorderStyle that is used to store intermediate changes to the row header border style.

singleVerticalBorderAdded
Type: System.Boolean

true to add a single vertical border to the result; otherwise, false.

singleHorizontalBorderAdded
Type: System.Boolean

true to add a single horizontal border to the result; otherwise, false.

isFirstDisplayedRow
Type: System.Boolean

true if the row is the first row displayed in the DataGridView; otherwise, false.

isLastVisibleRow
Type: System.Boolean

true if the row is the last row in the DataGridView that has its Visible property set to true; otherwise, false.

Return Value

Type: System.Windows.Forms.DataGridViewAdvancedBorderStyle
A DataGridViewAdvancedBorderStyle that represents the new border style used.

The DataGridView control internally calls the AdjustRowHeaderBorderStyle method to determine the appearance of the borders for the row header cells. The DataGridView control typically uses the value of the AdvancedRowHeadersBorderStyle property for the dataGridViewAdvancedBorderStyleInput parameter.

Notes to Inheritors

Override this method if you want to customize the appearance of the borders of row header cells.

The following code example demonstrates how to override the AdjustRowHeaderBorderStyle method to customize the borders of the row header cells. This code example is part of a larger example provided for the DataGridViewAdvancedBorderStyle class.

public override DataGridViewAdvancedBorderStyle AdjustRowHeaderBorderStyle(
    DataGridViewAdvancedBorderStyle dataGridViewAdvancedBorderStyleInput,
    DataGridViewAdvancedBorderStyle dataGridViewAdvancedBorderStylePlaceHolder,
    bool singleVerticalBorderAdded,
    bool singleHorizontalBorderAdded,
    bool isFirstDisplayedRow,
    bool isLastDisplayedRow)
{
    // Customize the top border of the first row header and the 
    // right border of all the row headers. Use the input style for  
    // all other borders.
    dataGridViewAdvancedBorderStylePlaceHolder.Top = isFirstDisplayedRow ?
        DataGridViewAdvancedCellBorderStyle.InsetDouble :
        DataGridViewAdvancedCellBorderStyle.None;
    dataGridViewAdvancedBorderStylePlaceHolder.Right =
        DataGridViewAdvancedCellBorderStyle.OutsetDouble;

    dataGridViewAdvancedBorderStylePlaceHolder.Left =
        dataGridViewAdvancedBorderStyleInput.Left;
    dataGridViewAdvancedBorderStylePlaceHolder.Bottom =
        dataGridViewAdvancedBorderStyleInput.Bottom;

    return dataGridViewAdvancedBorderStylePlaceHolder;
}
