[解决办法]
看了一下msdn里的sample需要在createrow的时候把index加button的commmandargument里面去
这里：
ms-help://MS.MSDN.vAug06.en/cpref16/html/E_System_Web_UI_WebControls_GridView_RowCommand.htm
<%@ Page language= "C# " %>
<script runat= "server ">
void CustomersGridView_RowCommand(Object sender, GridViewCommandEventArgs e)
{
// If multiple buttons are used in a GridView control, use the
// CommandName property to determine which button was clicked.
if(e.CommandName== "Add ")
{
// Convert the row index stored in the CommandArgument
// property to an Integer.
int index = Convert.ToInt32(e.CommandArgument);
// Retrieve the row that contains the button clicked
// by the user from the Rows collection.
GridViewRow row = CustomersGridView.Rows[index];
// Create a new ListItem object for the customer in the row.
ListItem item = new ListItem();
item.Text = Server.HtmlDecode(row.Cells[2].Text);
// If the customer is not already in the ListBox, add the ListItem
// object to the Items collection of the ListBox control.
if (!CustomersListBox.Items.Contains(item))
{
CustomersListBox.Items.Add(item);
}
}
}
void CustomersGridView_RowCreated(Object sender, GridViewRowEventArgs e)
{
// The GridViewCommandEventArgs class does not contain a
// property that indicates which row 's command button was
// clicked. To identify which row 's button was clicked, use
// the button 's CommandArgument property by setting it to the
// row 's index.
if(e.Row.RowType == DataControlRowType.DataRow)
{
// Retrieve the LinkButton control from the first column.
LinkButton addButton = (LinkButton)e.Row.Cells[0].Controls[0];
// Set the LinkButton 's CommandArgument property with the
// row 's index.
addButton.CommandArgument = e.Row.RowIndex.ToString();
}
}
