DataGridView – 当我按下输入它进入下一个单元格

我有一个5列的datagridview，当我按“enter”它进入下一个单元格，当它到达行的末尾，当我按Enter键它添加一个新的行，但我的问题是当我移动到上一个我按下后输入它跳行，不会去下一个单元格，任何帮助？

public partial class Form1 : Form { public static int Col; public static int Row; public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { dataGridView1.AllowUserToAddRows = false; dataGridView1.Rows.Add(); } private void dataGridView1_CellEnter(object sender, DataGridViewCellEventArgs e) { Col = dataGridView1.CurrentCellAddress.X; Row = dataGridView1.CurrentCellAddress.Y; } private void Form1_KeyPress(object sender, KeyPressEventArgs e) { if (e.KeyChar == (int)Keys.Enter) { if (Col + 1 < 5) { dataGridView1.CurrentCell = dataGridView1[Col + 1, Row]; } else { dataGridView1.Rows.Add(); dataGridView1.CurrentCell = dataGridView1[Col - 4, Row + 1]; } } } } 

Answer 1

忘记CellEnter事件和Form1_KeyPress事件。 只需处理dataGridView1_KeyDown事件，如下所示：

  private void dataGridView1_KeyDown(object sender, KeyEventArgs e) { if (e.KeyData == Keys.Enter) { int col = dataGridView1.CurrentCell.ColumnIndex; int row = dataGridView1.CurrentCell.RowIndex; if (col < dataGridView1.ColumnCount - 1) { col ++; } else { col = 0; row++; } if (row == dataGridView1.RowCount) dataGridView1.Rows.Add(); dataGridView1.CurrentCell = dataGridView1[col, row]; e.Handled = true; } } 

请注意，我稍微更改了代码，并记得将Handled事件属性设置为true，否则它将处理默认行为。

干杯!

这对我有用

 private void dataGridView1_KeyDown(object sender, KeyEventArgs e) { if (e.KeyData == Keys.Enter) { e.SuppressKeyPress = true; int row = dataGridView1.CurrentRow.Index; int col = dataGridView1.CurrentCell.ColumnIndex; } }

试试这个：

 bool notlastColumn = true; 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; int i = irow; if (keyData == Keys.Enter) { if (icolumn == dataGridView1.Columns.Count - 1) { //dataGridView1.Rows.Add(); if (notlastColumn == true) { dataGridView1.CurrentCell = dataGridView1.Rows[i].Cells[0]; } dataGridView1.CurrentCell = dataGridView1[0, irow + 1]; } else { dataGridView1.CurrentCell = dataGridView1[icolumn + 1, irow]; } return true; } else if (keyData == Keys.Escape) { this.Close(); return true; } //below is for escape key return return base.ProcessCmdKey(ref msg, keyData); //below is for enter key return return base.ProcessCmdKey(ref msg, keyData); } 

只需复制并粘贴代码即可。

只有你应该在表单中有网格。

您可以做的是处理KeyDown事件以检查是否按下了返回键，您取消事件并告诉应用程序在datagridview中使用所选的+1索引：

 private void dataGridView1_KeyDown(object sender, KeyEventArgs e) { if (e.KeyData == Keys.Enter) { int column = dataGridView1.CurrentCell.ColumnIndex; int row = dataGridView1.CurrentCell.RowIndex; dataGridView1.CurrentCell = dataGridView1[column, row+1]; e.Handled=true; } } 

为防止出现问题，您还应插入一个子句，以检查用户按下返回后是否有可用的项目。

使用此解决方案：

 private void Form1_Load(object sender, EventArgs e) { dtg.AllowUserToAddRows = false; } protected override bool ProcessCmdKey(ref Message msg, Keys keyData) { int iCol = dtg.CurrentCell.ColumnIndex; int iRow = dtg.CurrentCell.RowIndex; if (keyData == Keys.Enter) { if (iCol == dtg.ColumnCount - 1) { if (iRow + 1 == dtg.RowCount) { dtg.Rows.Add(); } dtg.CurrentCell = dtg[0, iRow + 1]; } else { dtg.CurrentCell = dtg[iCol + 1, iRow]; } return true; } else if (keyData == Keys.Escape) { Close(); return true; } return base.ProcessCmdKey(ref msg, keyData); } 

祝好运 …

因为按下在datagridview单元格上输入时，keyDown envent不会触发，这将是最好的感谢@Nagarjun

 bool notlastColumn = true; 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; int i = irow; if (keyData == Keys.Enter) { if (icolumn == dataGridView1.Columns.Count - 1) { //dataGridView1.Rows.Add(); if (notlastColumn == true) { dataGridView1.CurrentCell = dataGridView1.Rows[i].Cells[0]; } dataGridView1.CurrentCell = dataGridView1[0, irow + 1]; } else { // to pass hidden cell, because will fire exception //exception: Current cell cannot be set to an invisible cell // the do while loop will enable you to pass any hidden cell do { icolumn++; } while (!dgv[icolumn, irow].Visible); dataGridView1.CurrentCell = dataGridView1[icolumn, irow]; } return true; } else if (keyData == Keys.Escape) { this.Close(); return true; } //below is for escape key return return base.ProcessCmdKey(ref msg, keyData); 

}

只需按下按键即可向右移动…

 private void datagridview_KeyDown(object sender, KeyEventArgs e) { if (e.KeyCode == Keys.Enter) { SendKeys.Send("{Right}"); } }
