示例
下面的代码示例演示如何重写 AdjustCellBorderStyle 方法以自定义单元格的边框。 此代码示例是为 DataGridViewAdvancedBorderStyle 类提供的一个更大示例的一部分。
public override DataGridViewAdvancedBorderStyle AdjustCellBorderStyle(
DataGridViewAdvancedBorderStyle dataGridViewAdvancedBorderStyleInput,
DataGridViewAdvancedBorderStyle dataGridViewAdvancedBorderStylePlaceHolder,
bool singleVerticalBorderAdded,
bool singleHorizontalBorderAdded,
bool firstVisibleColumn,
bool firstVisibleRow)
{
// Customize the top border of cells in the first row and the
// right border of cells in the first column. Use the input style
// for all other borders.
dataGridViewAdvancedBorderStylePlaceHolder.Left = firstVisibleColumn ?
DataGridViewAdvancedCellBorderStyle.OutsetDouble :
DataGridViewAdvancedCellBorderStyle.None;
dataGridViewAdvancedBorderStylePlaceHolder.Top = firstVisibleRow ?
DataGridViewAdvancedCellBorderStyle.InsetDouble :
DataGridViewAdvancedCellBorderStyle.None;
dataGridViewAdvancedBorderStylePlaceHolder.Right =
dataGridViewAdvancedBorderStyleInput.Right;
dataGridViewAdvancedBorderStylePlaceHolder.Bottom =
dataGridViewAdvancedBorderStyleInput.Bottom;
return dataGridViewAdvancedBorderStylePlaceHolder;
}
Public Overrides Function AdjustCellBorderStyle( _
ByVal dataGridViewAdvancedBorderStyleInput As DataGridViewAdvancedBorderStyle, _
ByVal dataGridViewAdvancedBorderStylePlaceHolder As DataGridViewAdvancedBorderStyle, _
ByVal singleVerticalBorderAdded As Boolean, _
ByVal singleHorizontalBorderAdded As Boolean, _
ByVal firstVisibleColumn As Boolean, _
ByVal firstVisibleRow As Boolean) As DataGridViewAdvancedBorderStyle
' Customize the top border of cells in the first row and the
' right border of cells in the first column. Use the input style
' for all other borders.
If firstVisibleColumn Then
dataGridViewAdvancedBorderStylePlaceHolder.Left = _
DataGridViewAdvancedCellBorderStyle.OutsetDouble
Else
dataGridViewAdvancedBorderStylePlaceHolder.Left = _
DataGridViewAdvancedCellBorderStyle.None
End If
If firstVisibleRow Then
dataGridViewAdvancedBorderStylePlaceHolder.Top = _
DataGridViewAdvancedCellBorderStyle.InsetDouble
Else
dataGridViewAdvancedBorderStylePlaceHolder.Top = _
DataGridViewAdvancedCellBorderStyle.None
End If
With dataGridViewAdvancedBorderStylePlaceHolder
.Right = dataGridViewAdvancedBorderStyleInput.Right
.Bottom = dataGridViewAdvancedBorderStyleInput.Bottom
End With
Return dataGridViewAdvancedBorderStylePlaceHolder
End Function
End Class
注解
控件 DataGridView 在内部调用 AdjustCellBorderStyle 该方法以确定单元格边框的外观。 该DataGridView控件通常使用dataGridViewAdvancedBorderStyleInput
参数的属性AdvancedCellBorderStyle值。
不支持该值 DataGridViewAdvancedCellBorderStyle.OutsetPartial 作为单元格的输入样式。
继承者说明
如果要自定义单元格边框的外观,请重写此方法。
