如何使用asp.net将数据从form1中的datalist传输到form2中的gridview [英] how to transfer datas from datalist in form1 to gridview in form2 using asp.net

问题描述

这是我的DataList.aspx代码

 <   asp：DataList     ID   =   DataList1    runat  < span class =code-keyword> =  server      ItemStyle-CssClass   =  item1  
   
                         DataKeyField   =  BookId    
   
        < span class =code-attribute>                   CellPadding   =  1    GridLines   = 两者 < span class =code-attribute>   RepeatColumns   =  1      BorderWidth   =  1px  
   
      < span class =code-attribute>                     onupdatecommand   =  DataList1_UpdateCommand < span class =code-attribute>   
   
  < span class =code-attribute>                         ondeletecommand   =  DataList1_DeleteCommand1    
   
          < span class =code-attribute>                 oneditcommand   =  DataList1_EditCommand    
   
                   
   
            < span class =code-attribute>               oncancelcommand   =  DataList1_CancelCommand1    ForeColor   = ＃ 333333    
   
            < span class =code-attribute>               onitemcommand   =  DataList1_ItemCommand   >  
 <   itemtemplate  >  
 
 <  < span class =code-leadattribute> fieldset     style   =  widt h：550px >

 <   / div  >  <   / span  >  <   / fieldset  > ;  
 <   / itemtemplate  >  

解决方案

使用会话存储数据表。



示例在填写数据表后的表单1中将数据存储在会话中

会话[ 数据] = dt; 

//这里dt是包含您数据的表格



在表格2中从数据表中获取数据

代码

 DataTable dt =  new  DataTable（）; 
 dt =（DataTable）会话[ 数据]; 

this is my DataList.aspx code

<asp:DataList ID="DataList1" runat="server"  ItemStyle-CssClass="item1"

           DataKeyField="BookId" 

            CellPadding="1" GridLines="Both" RepeatColumns="1"  BorderWidth="1px"

            onupdatecommand="DataList1_UpdateCommand" 

            ondeletecommand="DataList1_DeleteCommand1" 

            oneditcommand="DataList1_EditCommand" 

        

            oncancelcommand="DataList1_CancelCommand1" ForeColor="#333333" 

            onitemcommand="DataList1_ItemCommand" >      
         <itemtemplate>
     
      <fieldset style="width:550px">

      <span> <div id="divname" style="padding-removed5px;">
             <img src='Resources/<%#Eval("ImageUpload") %>' width="90px" height="90px" style="padding-left:40px" alt="No Image" /><br /> 
      BookName : <%#DataBinder.Eval(Container.DataItem, "BookName")%><br />
        Author : <%#DataBinder.Eval(Container.DataItem, "Author")%><br />
        Publisher : <%#DataBinder.Eval(Container.DataItem, "Publisher")%><br />
        Price : <%#DataBinder.Eval(Container.DataItem, "Price")%><br />
       
   <asp:ImageButton ID="ImgEdit" runat="server" ImageUrl="~/Resources\imagesneww.jpg" CommandName="Edit" />     
        <asp:ImageButton ID="ImageDelete" runat="server" ImageUrl="~/Resources\edit-delete-icon.png" CommandName="Delete" CausesValidation="false"/>
         <asp:ImageButton ID="ImageSend" runat="server" ImageUrl="~/Resources\send.jpg" CommandName="Send"  CausesValidation="false"/>
      </div></span></fieldset>
        </itemtemplate>

解决方案

Use Session to store Datatable.

Example In form 1 after filling your data table store your data in a session

Session["Data"] = dt;

//Here dt is the table containing your data

In form 2 get the data back from datatable
Code

DataTable dt = new DataTable();
dt = (DataTable)Session["Data"];
