Question

我有一个数据表，每行都有一个复选框。我想要检查复选框的行的每个列值。请告诉我如何实现这一点。这是我的代码。选中复选框后，我想要特定的行详细信息。

                grid1.Children.Add(B5);
                 row++;            
            }

        }


    }
    }

我没有使用datagrid。我使用网格内的按钮和复选框显示我的数据表内容。

You Can use below event of the datagridView

  private void dataGridView1_CurrentCellDirtyStateChanged(object sender, EventArgs e)
        {
            if (dataGridView1.IsCurrentCellDirty)
            {
                dataGridView1.CommitEdit(DataGridViewDataErrorContexts.Commit);
            }
        }

在我的示例中，CheckBox位于gridview的第1列中，当检查时，第2列中的值可以转到变量col

 private void dataGridView1_CellValueChanged(object sender, DataGridViewCellEventArgs e)
        {
            if (dataGridView1.Columns[e.ColumnIndex].Name == "Column1")
            {

                DataGridViewCheckBoxCell checkCell =
                   (DataGridViewCheckBoxCell)dataGridView1.
                    Rows[e.RowIndex].Cells["Column1"];
                if ((bool)checkCell.Value == true) {
                    int i = dataGridView1.CurrentRow.Index;
                    string col = dataGridView1.Rows[e.RowIndex].Cells["column2"].Value.ToString();
                }

            }
        }

选中复选框时如何选择数据表行？
