GridView的RowCommand事件中取得行索引

 

代码

    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; 
        }
    }
