Question

wpf datagrid绑定了数据 如果选中多行中怎么获取选中行的某列的值

Answer 1

private void fill_Datagrid(string sql)
{
cmd = new SqlCommand(sql, conn.getConn());
sda = new SqlDataAdapter();
sda.SelectCommand = cmd;
ds = new DataSet();
sda.Fill(ds);
dataGridView1.DataSource = ds.Tables[0];
dataGridView1.Columns[0].Visible = false;
}
其中sql＝“select 字段 from a，b，c where 字段 ＝？”；
sql是在数据库中查询语句。

Answer 2

DataRowView selectItem = datagird.SelectItem as DataRowView;

object obj = selectItem["columnName"] or selectItem[index];
