DataGridからボタンにフォーカスを移動するにはどうすればいいですか？

Question

protected override void Paint(Graphics g, Rectangle bounds, CurrencyManager source, int rowNum, Brush backBrush, Brush foreBrush, bool alignToRight) 
{ 
    RectangleF textBounds;// Bounds of text 
    Object cellData;// Object to show in the cell 

    DrawBackground(g, bounds, rowNum, backBrush);// Draw cell background 

    bounds.Inflate(-2, -2);// Shrink cell by couple pixels for text. 

    textBounds = new RectangleF(bounds.X, bounds.Y, bounds.Width, bounds.Height); 
    // Set text bounds. 
    cellData = this.PropertyDescriptor.GetValue(source.List[rowNum]); // Get data for this cell from data source. 

    g.DrawString(FormatText(cellData), this.Owner.Font, foreBrush, textBounds, this.StringFormat); 
    // Render contents 
    this.updateHostedControl();// Update floating hosted control. 
} 

// Would reposition, hide and show hosted control as needed. 
protected void updateHostedControl() 
{ 
    Rectangle selectedBounds = this.Owner.GetCellBounds(this.Owner.CurrentCell.RowNumber, this.Owner.CurrentCell.ColumnNumber); 
    // Get selected cell bounds. 
    // We only need to show hosted control if column is not read only, 
    // selected cell is in our column and not occluded by anything. 

    if (!this.ReadOnly && (this.ColumnOrdinal == this.Owner.CurrentCell.ColumnNumber) && 
     this.Owner.HitTest(selectedBounds.Left, selectedBounds.Top).Type == DataGrid.HitTestType.Cell && 
     this.Owner.HitTest(selectedBounds.Right, selectedBounds.Bottom).Type == DataGrid.HitTestType.Cell) 
    { 
     if (selectedBounds != this._bounds)// See if control bounds are already set. 
     { 
      this._bounds = selectedBounds; // Store last bounds. Note we can't use control's bounds 
      // as some controls are not resizable and would change bounds as they pleased. 
      this.HostedControl.Bounds = selectedBounds;// Update control bounds. 

      this.HostedControl.Focus(); 
      this.HostedControl.Update();// And update control now so it looks better visually. 
     } 

     if (!this.HostedControl.Visible)// If control is not yet visible... 
     { 
      this.HostedControl.Show();// Show it 
      this.HostedControl.Focus(); 
     } 
    } 
    else if (this.HostedControl.Visible)// Hosted control should not be visible. Check if it is. 
    { 
     this.HostedControl.Hide();// Hide it. 
    } 

} 

protected virtual void DrawBackground(Graphics g, Rectangle bounds, int rowNum, Brush backBrush) 
{ 
    Brush background = backBrush;// Use default brush by... hmm... default. 

    if ((null != background) && ((rowNum & 1) != 0) && !Owner.IsSelected(rowNum)) 
    {                 
     // If have alternating brush, row is odd and not selected... 
     background = _alternatingBrush;// Then use alternating brush. 
    } 
    else 
     background = new SolidBrush(Color.White); 

    g.FillRectangle(background, bounds);// Draw cell background 
} 

カスタムデータグリッドとボタンが付いていますが、データグリッドからボタンにフォーカスを移すコードを書くことができません。デフォルトのデータグリッドまたはボタンにフォーカスがあります。誰でも助けてくれます。私はキーを押したときにフォーカスを移したいと思っています。

アドバンスありがとうございます。

DataGridでKeyPressedイベントを使用し、Enterキーを押してからフォーカスボタンを押します。あなたが任意の特定の問題を抱えていけない場合、これは、動作するはずです：

private void datagrid_KeyPress(object sender, KeyPressEventArgs e) 
{ 
    if (e.KeyChar == (char)Keys.Enter) 
     button1.Focus(); 
}
