DNN中gridView中数据链接地址设定的两个实例

实例一，用HyperLink控件，数据绑定时增加链接地址：

UI代码： 

代码

< asp:GridView ID = " grdResult "  runat = " server "  CssClass = " DataGrid_Container "  AllowPaging = " False "     
   AutoGenerateColumns = " False "  BorderWidth = " 0 "   OnRowDataBound = " grdResult_RowDataBound "    >    
    < RowStyle CssClass = " DataGrid_Item "   />    
    < SelectedRowStyle CssClass = " DataGrid_SelectedItem "   />            
    < HeaderStyle CssClass = " DataGrid_Header "    />            
    < AlternatingRowStyle CssClass = " DataGrid_AlvternatingItem "   />       
    < Columns >                
        < asp:TemplateField HeaderText = " 选择 "    >    
            < ItemTemplate  >    
                < input id = " SelectId "  type = " checkbox "  value = ' <%# Eval("DocId") %> '   />      
                < asp:HiddenField id = " DocId "  value = ' <%# Eval("DocId") %> '  runat = " server "   />      
                < asp:HiddenField id = " DocType "  value = ' <%# Eval("DocType") %> '  runat = " server "   />      
             </ ItemTemplate >                     
        </ asp:TemplateField >    
        < asp:TemplateField  HeaderText = " 名称 "  HeaderStyle - HorizontalAlign = " Left "  ItemStyle - HorizontalAlign = " Left "   >    
            < ItemTemplate   >    
                < asp:Image ID = " imgFolder "  runat = " server "   />    
                < asp:HyperLink ID = " DocName "  Text = ' <%# Eval("DocName") %> '  runat = " server " ></ asp:HyperLink >    
            </ ItemTemplate >    
        </ asp:TemplateField >                            
        < asp:BoundField DataField = " FileSize "  HeaderText = " 文件大小(KB) "    />    
        < asp:BoundField DataField = " CreateDate "  HeaderText = " 修改时间 "  DataFormatString = " {0:yyyy年MM月dd日 HH:mm} "   />      
    </ Columns >                  
< / asp:GridView >   

 C#代码绑定方法一：

代码

protected   void  Page_Load( object  sender, System.EventArgs e)   
{   
     if ( ! Page.IsPostBack)   
    {   
        BindGridData();             
    }   
}   
private   void  BindGridData()   
{   
    List < DocumentInfo >  di = DocumentController.GetListDocument( this .UserId);   
     if  (di.Count  ==   0 )   
    {   
        di.Add( new  DocumentInfo());         
    }   
        grdResult.DataSource  =  di;   
        grdResult.DataBind();   
      
}     
  
// 数据绑定时增加链接地址   
protected   void  grdResult_RowDataBound( object  sender, GridViewRowEventArgs e)   
{              
     if  (e.Row.RowType  ==  DataControlRowType.DataRow )   
    {   
        HyperLink DocName  =  (HyperLink)e.Row.FindControl( " DocName " );                   
        Image imgFolder = (Image) e.Row.FindControl( " imgFolder " );   
         // List<DocumentInfo> di =e.Row.DataItem as List<DocumentInfo>;   
        HiddenField txtDocId  =  (HiddenField) e.Row.FindControl( " DocId " );   
        HiddenField txtDocType  =  (HiddenField)e.Row.FindControl( " DocType " );   
           
         // 根据表中的列判断是否有数据   
         if  (txtDocId.Value  ==   " 0 " )   
        {   
             int  cols  =  e.Row.Cells.Count;   
            TableCellCollection tc  =  e.Row.Cells;   
            tc.Clear();   
            tc.Add( new  TableCell());   
            tc[ 0 ].ColumnSpan  =  cols;   
            tc[ 0 ].Text  =   " 没有找到你要的资料。 " ;      
        }   
           
         if  (txtDocType.Value.Trim().ToLower()  ==   " fold " )   
        {   
            imgFolder.ImageUrl  =   this .ControlPath  +   " images/folder1.gif " ;   
             string  navUrl  =   " javascript:navurl(' "   +   " http:// "   +  Request.Url.Host  +  ResolveUrl( " ../Document/callIndex.aspx?FolderId= " );   
            DocName.NavigateUrl  =  navUrl  +  txtDocId.Value.Trim()  +   " ') " ;    
        }   
  
    }   
}  

 C#代码绑定方法二：

代码

// 绑定时设定链接地址   
protected   void  grdResult_RowDataBound( object  sender, GridViewRowEventArgs e)   
{              
     if  (e.Row.RowType  ==  DataControlRowType.DataRow  &&  e.Row.RowIndex  >=   0 )   
    {                   
        DataRowView dr = (DataRowView)e.Row.DataItem;   
         int  intTabID =  Common.GetTabId(PortalId,  " ReceiveAccount " );                    
        HyperLink likSendMsg  =  (HyperLink)e.Row.FindControl( " OptSendMsg " );   
          
         if  (intTabID  >=   0 )   
        {   
            likSendMsg.NavigateUrl  =  Globals.NavigateURL(intTabID,  "" ,  " fId= "   +  dr[ " UserId " ].ToString());                                    
        }    
    }   
}  

 

实例二，用ImageButton控件，当用户点击button时，通过事件处理程序按照DataKey的值，

进行转向链接或进行数据处理：

UI代码： 

代码

     < asp:GridView ID = " grdData "  runat = " server "  Visible = " False "  CssClass = " DataGrid_Container "  
        PagerSettings - Visible = " false "   BorderWidth = " 0px "   DataKeyNames = " RowId "  
        AutoGenerateColumns = " False "  AllowSorting = " True "  OnRowEditing = " grdData_RowEdit "  OnSorting = " grdData_Sorting "
        OnRowDeleting = " grdData_RowDeleting "   >
         < AlternatingRowStyle CssClass = " DataGrid_AlvternatingItem "   />
         < RowStyle CssClass = " DataGrid_Item "   />
         < HeaderStyle CssClass = " DataGrid_Header "   />        
         < Columns >
             < asp:TemplateField HeaderText = " 执行操作 " >
                 < ItemTemplate  >                    
                     < asp:ImageButton ID = " BtnUpdate "  runat = " server "   ToolTip = " 编辑 "  CommandName = " Edit "  ImageUrl = " ~/images/edit.gif "   />                         
                     < asp:ImageButton ID = " BtnDelete "  runat = " server "  CausesValidation = " False "  CommandName = " Delete "
                            ToolTip = " 删除 "  OnClientClick = " return confirm('确认要删除此记录吗？') "  ImageUrl = " ~/images/delete.gif " />  
                 </ ItemTemplate >
             </ asp:TemplateField >             
         </ Columns >
     </ asp:GridView >

 

C#代码：

代码

         protected   void  grdData_RowEdit( object  sender, GridViewEditEventArgs e)
        {           
             string  RowId  =  grdData.DataKeys[e.NewEditIndex].Value.ToString();           
            Response.Redirect(EditUrl( " RowId " ,RowId,  " EditForm " ));
        }

         protected   void  grdData_RowDeleting( object  sender, GridViewDeleteEventArgs e)
        {
             if  (ListController.DeleteRow(TableName, grdData.DataKeys[e.RowIndex].Value.ToString()))
            {
                Common.ShowSuccessFacebox( " 删除成功！ " , Page,  0 );
            }
             else
            {
                Common.ShowFailureFacebox( " 删除失败！ " , Page);
                 return ;
            }              
            grdData.EditIndex  =   - 1 ;            
            BindData();
        }
