如何在Enter键按下事件的数据视图中将焦点移动到下一个单元格

朋友们，我正在使用C＃处理Windows应用程序。 我正在使用datagridview来显示记录。 我需要的function是当我按下“Enter”键时，焦点应该转到下一个单元格（同一行的列）。 如果它是网格中的最后一列，那么焦点应该转到下一行的第一列。 我已经尝试过了

SendKeys.Send("{Tab}") 

在datagridview1_KeyDown和datagridview1_KeyPress事件中。 但重点是对角线向下移动。 请帮我解决这个问题。

Answer 1

 private void dataGridView1_KeyDown(object sender, KeyEventArgs e) { e.SuppressKeyPress = true; int iColumn = dataGridView1.CurrentCell.ColumnIndex; int iRow = dataGridView1.CurrentCell.RowIndex; if (iColumn == dataGridView1.Columncount-1) { if (dataGridView1.RowCount > (iRow + 1)) { dataGridView1.CurrentCell = dataGridView1[1, iRow + 1]; } else { //focus next control } } else dataGridView1.CurrentCell = dataGridView1[iColumn + 1, iRow]; } 

Answer 2

 protected override bool ProcessCmdKey(ref System.Windows.Forms.Message msg, System.Windows.Forms.Keys keyData) { int icolumn = dataGridView1.CurrentCell.ColumnIndex; int irow = dataGridView1.CurrentCell.RowIndex; if (keyData == Keys.Enter) { if (icolumn == dataGridView1.Columns.Count - 1) { dataGridView1.Rows.Add(); dataGridView1.CurrentCell = dataGridView1[0, irow + 1]; } else { dataGridView1.CurrentCell = dataGridView1[icolumn + 1, irow]; } return true; } else return base.ProcessCmdKey(ref msg, keyData); } } 

Answer 3

您可以使用datagridview的selectionchanged事件。 在你的forms

  private DataGridViewCell _celWasEndEdit; private void datagridview_SelectionChanged(object sender, EventArgs e) { if (MouseButtons != 0) return; if (_celWasEndEdit != null && datagridview.CurrentCell != null) { // if we are currently in the next line of last edit cell if (datagridview.CurrentCell.RowIndex == _celWasEndEdit.RowIndex + 1 && datagridview.CurrentCell.ColumnIndex == _celWasEndEdit.ColumnIndex) { int iColNew; int iRowNew = 0; if (_celWasEndEdit.ColumnIndex >= datagridview.ColumnCount - 1) { iColNew = 0; iRowNew = dgvItems.CurrentCell.RowIndex; } else { iColNew = _celWasEndEdit.ColumnIndex + 1; iRowNew = _celWasEndEdit.RowIndex; } datagridview.CurrentCell = datagridview[iColNew, iRowNew]; } } _celWasEndEdit = null; } private void datagridview_CellEndEdit(object sender, DataGridViewCellEventArgs e) { _celWasEndEdit = dgvItems[e.ColumnIndex, e.RowIndex]; } 

Answer 4

 bool notlastColumn =true; //class level variable--- to check either last column is reached or not private void dataGridView1_CellEndEdit(object sender, DataGridViewCellEventArgs e) { if (dataGridView1.ColumnCount - 1 == e.ColumnIndex) //if last column { KeyEventArgs forKeyDown = new KeyEventArgs(Keys.Enter); notlastColumn = false; dataGridView1_KeyDown(dataGridView1, forKeyDown); } else { SendKeys.Send("{up}"); SendKeys.Send("{right}"); } } private void dataGridView1_KeyDown(object sender, KeyEventArgs e) { if (e.KeyCode == Keys.Enter && notlastColumn) //if not last column move to nex { SendKeys.Send("{up}"); SendKeys.Send("{right}"); } else if (e.KeyCode == Keys.Enter) { SendKeys.Send("{home}");//go to first column notlastColumn = true; } } 

Answer 5

即使我尝试的代码将焦点移动到下一个单元格，它们在单元格处于编辑模式时影响鼠标单击。 这就是我最终提出的。

  bool _dgv_list_cellEndEdit = false; // class level variable void dataGridView1_KeyDown(object sender, KeyEventArgs e) { if (e.KeyData == Keys.Enter) { e.SuppressKeyPress=true; SendKeys.Send("{Tab}"); } } void dataGridView1_CellBeginEdit(object sender, DataGridViewCellCancelEventArgs e) { _dgv_list_cellEndEdit=true; } void dataGridView1_MouseDown(object sender, MouseEventArgs e) { _dgv_list_cellEndEdit=false; } void dataGridView1_CellEndEdit(object sender, DataGridViewCellEventArgs e) { if(_dgv_list_cellEndEdit) { _dgv_list_cellEndEdit=false; SendKeys.Send("{Up}"); SendKeys.Send("{Tab}"); } }
