无法在动态DataGrid中添加分页 [英] Cannot add paging in dynamic datagrid

问题描述

我在程序中使用动态datagrid
我的代码在这里

I am using dynamic datagrid in my program
my code goes here

  System.Web.UI.WebControls.DataGrid DataGrid1 = new System.Web.UI.WebControls.DataGrid();
 protected void Page_Load(object sender, EventArgs e)
    {
  if (!IsPostBack)
        {            
            CreateGrid();
        }
}
   private void CreateGrid()
    {          
        DataGrid1.AllowPaging = true;
        DataGrid1.PageSize = 5; 
        DataGrid1.ItemCreated += new System.Web.UI.WebControls.DataGridItemEventHandler(dgRt_ItemCreated);
        DataGrid1.ItemDataBound += new System.Web.UI.WebControls.DataGridItemEventHandler(dgRt_ItemDataBound);     
        DataGrid1.ItemCommand += new    System.Web.UI.WebControls.DataGridCommandEventHandler(DataGrid1_ItemCommand);     
        DataGrid1.Attributes.Add("runat", "server");     
        DataGrid1.ID = "abcd";
        DataTable dt = new DataTable();
        dt = partyPub.select_guest();      
                DataGrid1.DataSource = dt;
                DataGrid1.DataBind(); 
//my problem goes here
        DataGrid1.PageIndexChanged += new DataGridPageChangedEventHandler(dgRt_PageIndexChanged);
        Form.Controls.Add(DataGrid1);    
     
    }
 private void dgRt_PageIndexChanged(object source, System.Web.UI.WebControls.DataGridPageChangedEventArgs e)
    {
        DataGrid1.CurrentPageIndex = e.NewPageIndex;
        CreateGrid();
    }

在这里，我的pageIndex更改没有触发.当我定义DataGrid1.PageSize = 5时，它仅显示五个记录；与<和>没有页码的按钮.
我无法在此处添加分页

如何处理动态Datagrid中的分页
请帮我解决这个问题

在此先感谢

here my pageIndex changed didnot fire. it showed only five records as I defined DataGrid1.PageSize = 5; with < and > buttons without page numbers.
I cannot add pagination here

How to deal with pagination in dynamic Datagrid

推荐答案

问题出在PageIndex更改事件中..

而是这样使用..

The problem is in PageIndex Changed event..

Instead Use like this..

private void dgRt_PageIndexChanged(object source, System.Web.UI.WebControls.DataGridPageChangedEventArgs e)
    {
        DataGrid grid = (DataGrid)(source);
        grid.CurrentPageIndex = e.NewPageIndex;
         DataTable dt = new DataTable();
        dt = partyPub.select_guest();      
        grid.Datasource = dt;
        grid.DataBind();       
    }

希望它能工作..

Hope it works..
