How to handle the double-click event in DataGridView?

You can handle the double-click event in a DataGridView by following these steps:

  1. Open the Form Designer, locate the double click event in the properties of the DataGridView control (double click the DataGridView control itself), which will automatically generate an event handler function.
  2. Write specific handling logic in the generated event handling function, such as obtaining the row and column information of a double click, and then performing corresponding operations.

Here is the sample code:

private void dataGridView1_CellDoubleClick(object sender, DataGridViewCellEventArgs e)
    // 获取双击的行和列信息
    int rowIndex = e.RowIndex;
    int colIndex = e.ColumnIndex;

    // 获取双击的单元格的值
    string cellValue = dataGridView1.Rows[rowIndex].Cells[colIndex].Value.ToString();

    // 在此处添加具体的处理逻辑,例如弹出提示框显示单元格的值
    MessageBox.Show("双击的单元格的值为:" + cellValue);

By following the above steps, you can handle double-click events in the DataGridView and implement custom logic operations.
