情况1：

使用dataSource绑定的时候使用一个页面变量，GridViewFlow_RowDeleting先执行，紧接着SqlDataSourceFlow_Deleting

private int rowIndex;
    protected void GridViewFlow_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {
        rowIndex = e.RowIndex;
    }
    protected void SqlDataSourceFlow_Deleting(object sender, SqlDataSourceCommandEventArgs e)
    {
        e.Command.Parameters["v_spfabh"].Value = GridViewFlow.DataKeys[rowIndex]["spfabh"].ToString();
        e.Command.Parameters["v_qztz"].Value = GridViewFlow.DataKeys[rowIndex]["qztz"].ToString();
        e.Command.Parameters["v_hztz"].Value = GridViewFlow.DataKeys[rowIndex]["hztz"].ToString();
        e.Command.Parameters["v_gwbh"].Value = GridViewFlow.DataKeys[rowIndex]["gwbh"].ToString();
        e.Command.Parameters["v_gzlx"].Value = GridViewFlow.DataKeys[rowIndex]["gzlx"].ToString();
        e.Command.Parameters["v_czr"].Value = sysUser.Name;
    }

情况2：使用tableAdapter

protected void GridViewApproval_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {
        try
        {
            DataSetClass.ApprovalStateDataTable dt = new DataSetClass.ApprovalStateDataTable();
            DataSetClassTableAdapters.ApprovalStateTableAdapter ta = new DataSetClassTableAdapters.ApprovalStateTableAdapter();
            ta.P_DELCONTRACTSTATE(GridViewApproval.DataKeys[e.RowIndex]["HTZTZ"].ToString(), sysUser.Name);
            this.ShowStateList();
        }
        catch (Exception ex)
        {
            WebAction.MessageBox(this, "add", ex.Message, null);
        }
    }

需要注意的：如果没使用datasource进行页面的绑定的话，删除或其他操作后，需要主动进行DataBind()的操作，以便删除后能够刷新显示为删除后的列表数据。
