我的表单中有datagridview1
,其中有一列,使用以下代码隐藏其标题的行数不受限制...
dataGridView1.RowHeadersVisible = false; // Hide Row Header
dataGridView1.ColumnHeadersVisible = false; // Hide Column Header
所以现在当我们专注于它时,第一行已被选中并突出显示。现在我想使用我的键盘向上和向下键使用下面的KeyDown
函数上下移动我的选择,当我按下ENTER时,选择单元格值应该转到类级变量,默认情况下首先是焦点行/ cell值也应设置为类级变量...
private void datagridview1_KeyDown(object sender, KeyEventArgs e)
{
if (dataGridView1.Visible == true)
{
if (e.KeyCode.Equals(Keys.Up))
{
MessageBox.Show("Move UP Row/Cell And Select It");
}
if (e.KeyCode.Equals(Keys.Down))
{
MessageBox.Show("Move Down Row/Cell And Select It");
}
if (e.KeyCode.Equals(Keys.Enter))
{
MessageBox.Show("Send Selected Cell Value To Class Level Variable");
}
e.Handled = true;
}
}
目前我有一些包含datagridview CELL值的类级别变量,我使用下面的代码获取CellClick
但是我想使用高级代码在键上执行此功能...
private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
value = dataGridView1.Rows[e.RowIndex].Cells[0].Value.ToString();
}
我的班级变量就像......
public partial class Form1: Form
{
string value = "";
public MainForm()
{
InitializeComponent();
}
}
那我怎么能用C#...... ???
来做对于UP / DOWN选择,我使用了以下代码及其工作原理。那么现在如何按ENTER键将所选单元格值发送到类级变量...... ???
private void selectUpRow()
{
DataGridView dgv = dataGridView1;
int totalRows = dgv.Rows.Count;
int rowIndex = dgv.SelectedCells[0].OwningRow.Index;
if (rowIndex == 0)
return;
int colIndex = dgv.SelectedCells[0].OwningColumn.Index;
DataGridViewRow selectedRow = dgv.Rows[rowIndex];
dgv.ClearSelection();
dgv.Rows[rowIndex - 1].Cells[colIndex].Selected = true;
}
private void selectDownRow()
{
DataGridView dgv = dataGridView1;
int totalRows = dgv.Rows.Count;
int rowIndex = dgv.SelectedCells[0].OwningRow.Index;
if (rowIndex == totalRows - 1)
return;
int colIndex = dgv.SelectedCells[0].OwningColumn.Index;
DataGridViewRow selectedRow = dgv.Rows[rowIndex];
dgv.ClearSelection();
dgv.Rows[rowIndex + 1].Cells[colIndex].Selected = true;
}
答案 0 :(得分:0)
所以最后我通过尝试Bla Bla Bla来实现它。以下是代码的简短答案......
public void SearchFunc()
{
cursorPos = 0;
docReadCount = 0;
flag:
for (int i = cursorPos; i < docEndPos; i++)
{
if (i + 1 == docEndPos|| i == docEndPos)
{
if(docReadCount == 1) return;
cursorPos = 0;
docReadCount++;
goto flag;
}
if (doc.Range(i, i+ 1).Text == "@" ||
doc.Range(i, i+ 1).Text == "&" ||
doc.Range(i, i+ 1).Text == "*")
{
//do something
}
}
}
