GridView－ －事件总结（欧耶）

－－经过潜心单位修炼中有如下杰作慢慢看哇卡卡。

1.点击标题排序 2.分页

protected   void  GridView1_PageIndexChanging( object  sender, GridViewPageEventArgs e)
     ... {
        GridView1.PageIndex = e.NewPageIndex;
        BindGrid();
    }

3编辑

    protected   void  GridView1_RowEditing( object  sender, GridViewEditEventArgs e)
     ... {
        GridView1.EditIndex = e.NewEditIndex;
        BindGrid();
    }

4更新功能

//   更新（- -口水吧功能），设置了OnRowEditing="GridView1_RowEditing"。 
     protected   void  GridView1_RowUpdating( object  sender, GridViewUpdateEventArgs e)
{
         int  id;
         string   xiaozhu;            
         //  下面得到主建
        id  =   int .Parse(GridView1.Rows[e.RowIndex].Cells[ 0 ].Text);
        // 下面得到更新的内容
        fxiaozhu;  =  ((TextBox)GridView1.Rows[e.RowIndex].Cells[ 1 ].Controls[ 0 ]).Text;
        SqlConnection cnn  =   new  SqlConnection( " 保密 " );
         try
       {
                  cnn.Open();
                   // 这里写更新
                 SqlCommand cmd  =   new  SqlCommand( " 保密 " )
                cmd.ExecuteNonQuery();
      } catch ()
      {
      }
       finally
      {
                   cnn.Close();
      }
        GridView1.EditIndex  =   - 1 ;
        BindGrid();
}

 

5删除

  protected   void  GridView1_RowDeleting( object  sender, GridViewDeleteEventArgs e)
     ... {
        int index = e.RowIndex;
        DataKey key = GridView1.DataKeys[index];
         int id = Convert.ToInt32(key.Value.ToString());
      //省略..因为偶懒的写了～～呵呵
  
        GridView1.EditIndex = -1;
        BindGrid();
    }

 

//   为了实现每列都可以自动点击排序，可以设置allowsorting=true,然后设置OnSorting="GridView1_Sorting"，或者直接点事件～～别告诉我你不知道在那里～～那来的砖头

   protected   void  GridView1_Sorting( object  sender, GridViewSortEventArgs e)
     ... {
        ViewState["sortexpression"] = e.SortExpression;
//设置viewsate来保存每次排序时的顺序
        if (ViewState["sortdirection"] == null)
        ...{
            ViewState["sortdirection"] = "asc";
        }
        else
        ...{
            if (ViewState["sortdirection"].ToString() == "asc")
            ...{
                ViewState["sortdirection"] = "desc";
            }
            else
            ...{
                ViewState["sortdirection"] = "asc";
            }
        }
        BindGrid();
    }
