作者: / 发布于2017/2/4/ 356

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)  
    {  
        if (e.Row.RowType == DataControlRowType.DataRow)//如果是为数据行  
        {  
            ImageButton imgbtnup = (ImageButton)e.Row.Cells[1].FindControl("btnMoveUp");//找控件  
            imgbtnup.CommandArgument = e.Row.RowIndex.ToString();//设置与此BUTTON关联的命令参数  
            imgbtnup.Visible = e.Row.RowIndex != 0;   
            ImageButton imgbtndown = (ImageButton)e.Row.Cells[2].FindControl("btnMoveDown");  
            imgbtndown.CommandArgument = e.Row.RowIndex.ToString();  
            imgbtndown.Visible = e.Row.RowIndex != ((DataSet)((GridView)sender).DataSource).Tables[0].Rows.Count - 1;  
        }  
    }  
  
    protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)  
    {  
        if (e.CommandName == "MoveUp")  
        {  
            int index = Convert.ToInt32(e.CommandArgument);//取的行索引  
            DataKey key = this.GridView1.DataKeys[index];  
            string keyval = key.Value;//取得主键  
        }  
        else if (e.CommandName == "MoveDown")  
        {  
            int index = Convert.ToInt32(e.CommandArgument);  
            DataKey key = this.GridView1.DataKeys[index];  
            string keyval = key.Value;   
        }  
    }
