DataGridViewCell.GetErrorIconBounds(Graphics, DataGridViewCellStyle, Int32) 方法

定义

如果显示了单元格的错误图标,则返回环绕该图标的边框。Returns the bounding rectangle that encloses the cell's error icon, if one is displayed.

protected:
 virtual System::Drawing::Rectangle GetErrorIconBounds(System::Drawing::Graphics ^ graphics, System::Windows::Forms::DataGridViewCellStyle ^ cellStyle, int rowIndex);
protected virtual System.Drawing.Rectangle GetErrorIconBounds (System.Drawing.Graphics graphics, System.Windows.Forms.DataGridViewCellStyle cellStyle, int rowIndex);
abstract member GetErrorIconBounds : System.Drawing.Graphics * System.Windows.Forms.DataGridViewCellStyle * int -> System.Drawing.Rectangle
override this.GetErrorIconBounds : System.Drawing.Graphics * System.Windows.Forms.DataGridViewCellStyle * int -> System.Drawing.Rectangle
Protected Overridable Function GetErrorIconBounds (graphics As Graphics, cellStyle As DataGridViewCellStyle, rowIndex As Integer) As Rectangle

参数

graphics
Graphics

单元格的图形上下文。The graphics context for the cell.

cellStyle
DataGridViewCellStyle

要应用到单元格的 DataGridViewCellStyleThe DataGridViewCellStyle to be applied to the cell.

rowIndex
Int32

该单元格的父行索引。The index of the cell's parent row.

返回

Rectangle

如果显示了单元格的错误图标,则为包围该图标的 Rectangle;否则为 EmptyThe Rectangle that bounds the cell's error icon, if one is displayed; otherwise, Empty.

注解

调用此方法时,会动态计算单元格的错误图标区域的大小。The size of the cell's error icon area is computed dynamically when this method is called. 基类实现始终返回 Rectangle.EmptyThe base class implementation always returns Rectangle.Empty.

当读取属性时,会在内部调用此方法 ErrorIconBoundsThis method is called internally when the ErrorIconBounds property is read.
