DataGridView的一项功能

DataGridView有没有这样的功能，当点击其中的一行时，获取该行的数据，用于填充编辑界面。

这个功能相信大家都做过。

说说思路，最好给点代码实例。。。 --------------------编程问答-------------------- DataGridView1.CurrentRow获取当前单元格所在的行。 --------------------编程问答--------------------

DataGridView1.CurrentRow获取当前单元格所在的行。

这个功能就是跟编辑该行是一样的，获取数据，添加显示到其他控件上 --------------------编程问答-------------------- 补个，

引用 1 楼 hudenq 的回复:

DataGridView1.CurrentRow获取当前单元格所在的行。

同意这个 --------------------编程问答-------------------- 通常的做法应该是：取得在datagridview中的行的主键，然后将相应记录显示在详细视图中，在编辑保存详细视图。 --------------------编程问答-------------------- 事件cellclick和cellcontentclick
前者点击行时触发，后者点击行的内容时发生，区别，如果改行某个列为null，前者可以触发，后者不触发



private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)

        {

            if (e.RowIndex < 0 || e.RowIndex >= this.dataGridView1.Rows.Count - 1)

                return;

            this.listBox1.Items.Clear();

            try

            {

                eindex = e.RowIndex;

                string racebh = this.dataGridView1.Rows[e.RowIndex].Cells["match_ID"].Value.ToString();//获取当前行match_ID列的数据

                RaceBh = racebh;

            //做相关处理。

            }

            catch (Exception ex)

            { MessageBox.Show(ex.Message); }

        }

--------------------编程问答-------------------- 这个很不错，支持 --------------------编程问答-------------------- 顶6楼！居然加了这个判断
if (e.RowIndex < 0 || e.RowIndex >= this.dataGridView1.Rows.Count - 1)
记得想当年我第一次写C#的时候就没加～～囧～～～ --------------------编程问答-------------------- 直接使用：

dataGridView1.CurrentRow获取当前单元格所在的行。 --------------------编程问答-------------------- 学习，吸收。

--------------------编程问答-------------------- 6楼正解 --------------------编程问答-------------------- 学习。。。。。。。。。。。 --------------------编程问答-------------------- --------------------编程问答--------------------

注意不错哦。 --------------------编程问答-------------------- 注意积累。 --------------------编程问答-------------------- 可以使用Binding --------------------编程问答--------------------
