DataGridView选择要在文本框中显示的行

Question

我有一个DataGridView（tblLoggedJobs），显示用户记录的作业列表。我需要管理员能够更新这些作业以显示作业的任何更新，或者注意作业是否已关闭。 我希望程序将所选ROW中的数据显示到右侧的文本框中，但是我不知道如何获取此数据并根据所选行显示它。

Answer 1

您可以使用SelectedRows属性。

示例：

if(dataGridView1.SelectedRows.Count > 0) // make sure user select at least 1 row 
{
   string jobId = dataGridView1.SelectedRows[0].Cells[0].Value + string.Empty;
   string userId = dataGridView1.SelectedRows[0].Cells[2].Value + string.Empty;

   txtJobId.Text = jobId;
   txtUserId.Text = userId;
}

Answer 2

在cellclick事件中添加代码

if (e.RowIndex >= 0)
{
    //gets a collection that contains all the rows
    DataGridViewRow row = this.dataGridView1.Rows[e.RowIndex];
    //populate the textbox from specific value of the coordinates of column and row.
    txtid.Text = row.Cells[0].Value.ToString();
    txtfname.Text = row.Cells[1].Value.ToString();
    txtlname.Text = row.Cells[2].Value.ToString();
    txtcourse.Text = row.Cells[3].Value.ToString();
    txtgender.Text = row.Cells[4].Value.ToString();
    txtaddress.Text = row.Cells[5].Value.ToString();
}
