1.获取索引行与显示问题
int index = dataGridView1.CurrentRow.Index; //获取点击索引行
dataGridView1.Rows[index].Selected = true; //加亮显示
string curNo = this.dataGridView1.Rows[index].Cells[0].Value.ToString(); //取索引行的第一个单元格内容
int r = Convert.ToInt32(this.dataGridView1["Record_no", index].Value.ToString());
string no = this.dataGridView1["InBound_no", index].Value.ToString();
2.
int i = dataGridView1.CurrentRow.Index; //获取当前记录的索引号
this.dataGridView1.Rows[i].Selected = true; //加亮显示
string curN = this.dataGridView1["ZGOutNo", i].Value.ToString();
3.
private void showData()
{
try
{
conn = new OracleConnection(ConnectionString);
da = new OracleDataAdapter("SELECT Record_no,Tool_no,entrustDate,finishDate,Factory,beforeSize1,afterSize1,beforeSize2,afterSize2,beforeSize3,"
+ "afterSize3,beforeSize4,afterSize4,beforeSize5,afterSize5,importer,Insert_Time FROM T_ZG_maintenance", conn);
ds = new DataSet();
da.Fill(ds);
dataGridView2.DataSource = ds;
dataGridView2.DataMember = ds.Tables[0].ToString();
}
catch(Exception ex)
{
MessageBox.Show(ex.ToString());
}
finally
{
ds.Dispose();
}
}
4.
private void ShowData()
{
try
{
conn = new OracleConnection(ConnectionString);
da = new OracleDataAdapter(string.Format("SELECT Record_no,Tool_no,entrustDate,finishDate,Factory,beforeSize1,afterSize1,beforeSize2,afterSize2,beforeSize3,"
+ "afterSize3,beforeSize4,afterSize4,beforeSize5,afterSize5,importer,Insert_Time FROM T_ZG_maintenance Where Tool_no='{0}'", cmbTool_no.Text), conn);
ds = new DataSet();
da.Fill(ds);
da.Dispose();
this.bindingSource2.DataSource = ds.Tables[0];
this.bindingNavigator2.BindingSource = bindingSource2;
this.dataGridView2.DataSource = bindingSource2;
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
finally
{
ds.Dispose();
}
}
5.点击datagridview索引超出范围,必须为非负值并小于集合大小。
dgvTicketInfo.SelectedRows[0].Cells["ID"].Value报错
因为dgvTicketInfo.SelectedRows的默认selectionMode是 RowHeaderSelect,如果你点击行中某一个单元格,是选不到整行的!所以dgvTicketInfo.SelectedRows.Count实际上是零。你的那句话:
dgvTicketInfo.SelectedRows[0] 肯定要报索引超出范围了!
可以把selectionMode设成整行选择!当然也可以改进你的定位行和单元格的方式!比如通过当前单元格的行列下标,定位你的“ID”也可以!
