c# - 如何找出点击了哪个 DataGridView？

Question

我已经创建了一个 DataGridViews 数组，并为每个 gridview DataGridViewCellEventHandler 添加，我想在单击时更改当前 DataGridView 单元格值，要更改单元格值，您必须从数组中知道当前 DataGridView 索引为 dataGridView[i].Rows [colIndex].Cells[rowIndex].Value，
如何找出点击了哪个DataGridView？

这是我的代码。

DataGridView[] altGridViews=new DataGridView[10];
for (int i = 0; i < 10; i++)
{
 altGridViews[i]=new DataGridView();
 altGridViews[i].RowCount = 3;
 altGridViews[i].ColumnCount = 3;
 altGridViews[i].AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.Fill;
 altGridViews[i].CellClick += new         
 DataGridViewCellEventHandler(altGridView_Click);
 this.Controls.Add(altGridViews[i]);
}

和 DataGridView 甚至处理程序

protected void altGridView_Click(object sender, DataGridViewCellEventArgs e)
{
     int colIndex = e.ColumnIndex;
     int rowIndex = e.RowIndex;
 //todo: change current cell value
 //altGridViews[i].Rows[colIndex].Cells[rowIndex].Value="something";
} 

Answer 1

protected void altGridView_Click(object sender, DataGridViewCellEventArgs e)
{
    int colIndex = e.ColumnIndex;
    int rowIndex = e.RowIndex;
    var currentDataGridView = sender as DataGridView; //your grid
    currentDataGridView.Rows[colIndex].Cells[rowIndex].Value="something";
}
