GridView分页中遇到的问题 [英] Problem facing in GridView paging

问题描述

实际上我正在使用gridview1并将80条记录绑定到该gridview1，并且我将寻呼属性作为pagesize = 20.it成功绑定到gridvew。但我的问题是当我再次点击第二页时它只绑定了前20条记录。我正在给我的代码如下...

 <   asp：GridView     ID   =  gvInbox    runat   =  server < span class =code-attribute>  宽度  =  100％    AutoGenerateColumns   =  False    
   
                   DataKeyNames   =  MsgID     DataSourceID   = < span class =code-keyword> sdsInbox    
   
              < span class =code-attribute>     ondatabound   =  gvInbox_DataBound    
   
                   onselectedindexchanged   =  gvInbox_SelectedIndexChanged    
   
                   onrowcommand   =  gvInbox_RowCommand    onrowdatabound   =  gvInbox_RowDataBound    
   
                   AllowPaging   =  True    PageSize   =  20 < span class =code-attribute>   
   
  < span class =code-attribute>                 onpageindexchanging   =  gvInbox_PageIndexChanging >  
 <   pagersettings  >  
 position =Bottom
 pagebuttoncount =20/> 
 <   pagerstyle    < span class =code-attribute> backcolor   =  LightBlue >  
 height =30px
 verticalalign =Bottom
 horizo​​ntalalign =Center/> 

 受保护  void  gvInbox_PageIndexChanging（ object  sender，GridViewPageEventArgs e）
 {
 gvInbox.PageIndex = e.NewPageIndex; 
  //   gvInbox.DataSource = sdsInbox;  
 gvInbox.Page.DataBind（ ）; 
} 

解决方案

我不确定Page.DataBind（）;

这是有用的对我来说

  protected   void  gridView_PageIndexChanging（  object  sender，GridViewPageEventArgs e）
 {
 gridView.PageIndex = e.NewPageIndex; 
 gridView.DataSource =  / *  指定要绑定的数据集* /  
 gridView.DataBind（）; 
}

错误意味着您只有一个数据源n适用于gridview。在您的情况下，您使用 DataSourceID =sdsInbox以及 gvInbox_PageIndexChanging 绑定gridview。删除一个数据绑定，它会工作。

Actually i am taking gridview1 and binding 80 records to that gridview1 and i given paging properties as pagesize=20.it is binding to gridvew successfully. but my problem is when i click on second page again it is binding first 20 records only.i am giving my code below...

<asp:GridView ID="gvInbox" runat="server" Width="100%" AutoGenerateColumns="False" 

        DataKeyNames="MsgID" DataSourceID="sdsInbox" 

        ondatabound="gvInbox_DataBound" 

        onselectedindexchanged="gvInbox_SelectedIndexChanged" 

        onrowcommand="gvInbox_RowCommand" onrowdatabound="gvInbox_RowDataBound" 

        AllowPaging="True" PageSize="20" 

        onpageindexchanging="gvInbox_PageIndexChanging">
        <pagersettings>
          position="Bottom"           
          pagebuttoncount="20"/>
         <pagerstyle backcolor="LightBlue">
          height="30px"
          verticalalign="Bottom"
          horizontalalign="Center"/>

protected void gvInbox_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    gvInbox.PageIndex = e.NewPageIndex;
    //gvInbox.DataSource = sdsInbox;
    gvInbox.Page.DataBind();
}

解决方案

I am not sure about Page.DataBind();
this works for me

protected void gridView_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
   gridView.PageIndex = e.NewPageIndex;
   gridView.DataSource = /* Specify your dataset you want to bind here */
   gridView.DataBind();
}

The error means that Only one data source you can apply to the gridview. In your case you are binding the gridview using DataSourceID="sdsInbox" as well as in gvInbox_PageIndexChanging. Delete one databinding, it''ll work.
