本次问题解决了，谢谢大家的意见，现在结帖！！我采用的是
public void myDataGrid_ItemCommand(object sender,DataGridCommandEventArgs e)
{
int row =e.Item.ItemIndex;
if(e.CommandName=="Select")
{
txtno.Text = myDataGrid.Items[row].Cells[1].Text;
txtname.Text = myDataGrid.Items[row].Cells[2].Text; }
}
public void myDataGrid_ItemCommand(object sender,DataGridCommandEventArgs e)
{
int row =e.Item.ItemIndex;
if(e.CommandName=="Select")
{
txtno.Text = myDataGrid.Items[row].Cells[1].Text;
txtname.Text = myDataGrid.Items[row].Cells[2].Text; }
}

必杀技：
假设你绑定的DataSet的ID为ds！
TextBox1.Text=ds.Tables[0].Rows[row]["ZID"].ToString();//假设第一例绑定的字段名为ZID
TextBox2.Text= ds.Tables[0].Rows[row]["ID"].ToString();//假设第一例绑定的字段为ID
public void DataGrid1_ItemCommand(object sender,DataGridCommandEventArgs e)
{
int row =e.Item .ItemIndex;
if(e.CommandName=="Select")
{
TextBox1.Text=ds.Tables[0].Rows[row]["ZID"].ToString();//假设第一例绑定的字段名为ZID
TextBox2.Text= ds.Tables[0].Rows[row]["ID"].ToString();//假设第一例绑定的字段为ID
}
}

OnSelectedIndexChanged="IndexChange_Command"
void IndexChange_Command(Object sender, EventArgs e)
{
TextBox1.Text=ItemsGrid.SelectedItem.Cells[1].Text
TextBox2.Text= ItemsGrid.SelectedItem.Cells[2].Text
}
void IndexChange_Command(Object sender, EventArgs e)
{
TextBox1.Text=ItemsGrid.SelectedItem.Cells[1].Text
TextBox2.Text= ItemsGrid.SelectedItem.Cells[2].Text
}

请大家看看：我用的是 txtno.Text =e.Item.Cells[0].ToString ()或者txtno.Text = myDataGrid.SelectedItem.Cells[0].ToString ()或者txtno.Text =myDataGrid.Items[row].Cell[0].ToString()，但是结果都是 单击select按钮时却在textbox中显示“System.Web.UI.WebControls.TableCell”，而不显示相应的行数据， 这是为什么呢？

if(e.CommandName=="Select")
{
TextBox1.Text=e.Item.Cell[0].ToString();//第一列的值放入TextBox1
TextBox2.Text=e.Item.Cell[1].ToString();//第二列的值放入TextBox2
}

我采用了sgsh51的意见， 的确响应了事件，但是在txtbox文本框中出现的确是：“System.Web.UI.WebControls.TableCell” 可知这个是为什么么？？

获取当前行的不同列的值不就行了！

先添加一列选择按钮，假设DataGrid的ID为DataGrid1，两个TextBox的ID分别为TextBox1和TextBox2。
在
private void InitializeComponent()
{
}
中加入下面这句
this.DataGrid1.ItemCommand += new System.Web.UI.WebControls.DataGridCommandEventHandler(this.DataGrid1_ItemCommand);
public void DataGrid1_ItemCommand(object sender,DataGridCommandEventArgs e)
{
int row =e.Item .ItemIndex;
if(e.CommandName=="Select")
{
TextBox1.Text=DataGrid1.Items[row].Cell[0].ToString();//第一列的值放入TextBox1
TextBox2.Text=DataGrid1.Items[row].Cell[1].ToString();//第二列的值放入TextBox2
}
}
在
private void InitializeComponent()
{
}
中加入下面这句
this.DataGrid1.ItemCommand += new System.Web.UI.WebControls.DataGridCommandEventHandler(this.DataGrid1_ItemCommand);
public void DataGrid1_ItemCommand(object sender,DataGridCommandEventArgs e)
{
int row =e.Item .ItemIndex;
if(e.CommandName=="Select")
{
TextBox1.Text=DataGrid1.Items[row].Cell[0].ToString();//第一列的值放入TextBox1
TextBox2.Text=DataGrid1.Items[row].Cell[1].ToString();//第二列的值放入TextBox2
}
}
