public:
System::Drawing::Rectangle GetCellBounds(int row, int col);
public System.Drawing.Rectangle GetCellBounds (int row, int col);
member this.GetCellBounds : int * int -> System.Drawing.Rectangle
Public Function GetCellBounds (row As Integer, col As Integer) As Rectangle
参数
- row
- Int32
单元格的行号。
- col
- Int32
单元格的列号。
返回
一个 Rectangle,它定义当前单元格的角。
示例
下面的代码示例使用 GetCellBounds 方法返回 Rectangle 指定单元格的 。
private:
void dataGrid1_MouseDown( Object^ sender, MouseEventArgs^ e )
{
// Use the HitTest method to get a HitTestInfo object.
System::Windows::Forms::DataGrid::HitTestInfo^ hi;
DataGrid^ grid = dynamic_cast<DataGrid^>(sender);
hi = grid->HitTest( e->X, e->Y );
// Test if the clicked area was a cell.
if ( hi->Type == DataGrid::HitTestType::Cell )
{
// If it's a cell, get the GridTable and CurrencyManager of the
// clicked table.
DataGridTableStyle^ dgt = dataGrid1->TableStyles[ 0 ];
CurrencyManager^ myCurrencyManager = dynamic_cast<CurrencyManager^>(BindingContext[ myDataSet->Tables[ dataGrid1->DataMember ] ]);
// Get the Rectangle of the clicked cell.
Rectangle cellRect;
cellRect = grid->GetCellBounds( hi->Row, hi->Column );
// Get the clicked DataGridTextBoxColumn.
DataGridTextBoxColumn^ gridCol = dynamic_cast<DataGridTextBoxColumn^>(dgt->GridColumnStyles[ hi->Column ]);
// Insert code to edit the value.
}
}

// Get the Rectangle of the clicked cell.
Rectangle cellRect;
cellRect=grid.GetCellBounds(hi.Row, hi.Column);
// Get the clicked DataGridTextBoxColumn.
DataGridTextBoxColumn gridCol =
(DataGridTextBoxColumn) dgt.GridColumnStyles[hi.Column];
// Insert code to edit the value.
}
}
