c#在TabControl内部动态创建的DataGridView中查找SelectedRow

我有一个tabcontrol，datagridview是在tabcontrol的tabpage中动态创建的。我需要从活动数据网格视图中提取选定的行项目值。这个网格的名称也将被动态设置。我可以做些什么来从所选行中获取列值？以下是在表单加载事件中执行的代码

foreach (DataTable dtTable in Ds.Tables)
        {
DataGridView dgv = new DataGridView();
            //dgv.DataSource = dtTable;
            dgv.AllowUserToAddRows = false;
            dgv.AllowUserToDeleteRows = false;
            dgv.ColumnHeadersHeightSizeMode =     System.Windows.Forms.DataGridViewColumnHeadersHeightSizeMode.AutoSize;
            dgv.Dock = System.Windows.Forms.DockStyle.Fill;
            dgv.Location = new System.Drawing.Point(3, 3);
            dgv.Name = "dgv_" + dtTable.TableName;
            dgv.ReadOnly = true;
            dgv.Size = new System.Drawing.Size(725, 322);
            dgv.TabIndex = 0;
            dgv.AutoGenerateColumns = false;
            foreach (DataColumn dtCol in dtTable.Columns)
            {
                DataGridViewColumn column = new DataGridViewTextBoxColumn();
                column.FillWeight = 1;
                column.Name = dtCol.ColumnName;
                column.DataPropertyName = dtCol.ColumnName;
                dgv.Columns.Add(column);
            }

            //dgv.Columns.AddRange(columns);
            dgv.DataSource = null;
            dgv.DataSource = dtTable;

            lblInfo.Text = string.Format("Rows : {0} ; Columns : {1}", dtTable.Rows.Count, dtTable.Columns.Count);
            TabPage tpInstdata = new System.Windows.Forms.TabPage();
            tpInstdata.Controls.Add(dgv);
            tpInstdata.Location = new System.Drawing.Point(4, 22);
            tpInstdata.Name = "tp_" + dtTable.TableName;
            tpInstdata.Padding = new System.Windows.Forms.Padding(3);
            tpInstdata.Size = new System.Drawing.Size(725, 322);
            tpInstdata.TabIndex = 1;
            tpInstdata.Text = dtTable.TableName;
            tpInstdata.UseVisualStyleBackColor = true;
            tcInstTab.TabPages.Add(tpInstdata);
}

c#在TabControl内部动态创建的DataGridView中查找SelectedRow

将每个dgv连接到foreach循环中相同的SelectionChanged事件处理程序：

dgv.SelectionChanged += aDataGridView_SelectionChanged;

事件处理程序函数可能如下所示：

    private void aDataGridView_SelectionChanged(object sender, System.EventArgs e)
    {
        string aValue = ((DataGridView)sender).SelectedRows[0].Cells["ColumnOfYourInterest"].Value.ToString();
    }
