c# - Show localized display name for MetaTable and MetaColumn in ASP.NET Dynamic Data website -

-



i'm using visual studio 2017 asp.net dynamic data project template create website database crud operations models.

i'm setting displayname in database model's metatable, , can shown in asp.net dynamic data website, this:

[scaffoldtable(true)] [metadatatype(typeof(itemmetadata))] public class itemmodel {     public guid id { get; set; }     ...     ... }  [displayname("thisismyitemmodeldisplayname")] class itemmetadata {     [scaffoldcolumn(true)]     [display(order = 1)]     public guid id;      [scaffoldcolumn(true)]     [display(name = "thisisitemname", order = 3)]     public string itemname;      ... }

it's good, website can reflect , show string i've put in, website need support different locale languages, created customized attribute allow pass in resource string key, 

[attributeusage(attributetargets.class | attributetargets.field, allowmultiple = false)] public class localizedisplayname : attribute {     public localizedisplayname(string localizedstringkey)     {         this.stringkey = localizedstringkey;     }      public string stringkey { get; } }

use this:

[localizedisplayname("dynamicdatawebsite_model_item_localizeddisplayname")] class itemmetadata {     [scaffoldcolumn(true)]     [display(order = 1)]     public guid id;      [scaffoldcolumn(true)]     [localizedisplayname(name = "dynamicdatawebsite_model_item_column_itemname", order = 3)]     public string itemname;      ... }

and in website pages code showing model, can resolve localized string key resource file, localized string:

var target = metatable.attributes[typeof(localizedisplayname)]; var localizedstr = resources.strings.resourcemanager.getstring(((localizedisplayname)target).stringkey, cultureinfo.currentculture);

above code easy inject code in aspx.cs, gridview , etc., of binding logical behind scence, sample code visual studio dynamic data website template's list page showing list of values model:

<asp:gridview id="gridview1" runat="server" datasourceid="griddatasource" enablepersistedselection="true"         allowpaging="true" allowsorting="true" cssclass="ddgridview"         rowstyle-cssclass="td" headerstyle-cssclass="th" cellpadding="6">         <columns>             <asp:templatefield>                 <itemtemplate>                     <asp:linkbutton runat="server" commandname="edit" text="edit" onclientclick='return confirm("super admin, sure want edit item?");' />&nbsp;                     <asp:linkbutton runat="server" commandname="delete" text="delete"                                 onclientclick='return confirm("super admin, sure want delete item?");' />&nbsp;                     <asp:dynamichyperlink runat="server" text="details" />                 </itemtemplate>             </asp:templatefield>         </columns>          <pagerstyle cssclass="ddfooter" />         <pagertemplate>             <asp:gridviewpager runat="server" />         </pagertemplate>         <emptydatatemplate>             there no items in table.         </emptydatatemplate> </asp:gridview>

for here, want header row showing localized string marked in metatable's metacolumn, column itemname marked resource key

dynamicdatawebsite_model_item_column_itemname

so how can achieve generic way suits types of models?
