Hi In our MVC application we need to dispaly data from database in nested repeater..Categories in parent repeater and SubCategories in child repeater.
I tried doing it as follows.
public class VendorRegistrationStep3
{
public int Category_Id { get; set; }
public string Category_Name { get; set; }
public string Category_Code { get; set; }
public string Description { get; set; }
public bool delete_flag { get; set; }
public IEnumerable<subCategory> subCategoriesList { get; set; }
}
public class VendorRegistrationStep3List
{
public IEnumerable<VendorRegistrationStep3> categoriesList { get; set; }
}
public class subCategory
{
public int Subcategory_Id { get; set; }
public string Subcategory_Name { get; set; }
public string Subcategory_Code { get; set; }
public int categoryId { get; set; }
public string Description { get; set; }
public bool delete_flag { get; set; }
}
[HttpGet]
public ActionResult VendorRegistrationStep3()
{
var model = GetCategories();
return View(model);
}
public static IEnumerable<VendorRegistrationStep3List> GetCategories()
{
// Make sure my context gets disposed as soon as I'm done with it.
IEnumerable<VendorRegistrationStep3> categoryList;
using (var db = new bid_portalEntities())
{
// Pull all the questions and answers out in a single round-trip
var Categories = (from objcat in db.bp_category
select new VendorRegistrationStep3
{
Category_Code = objcat.Category_Code,
Category_Name = objcat.Category_Name,
Category_Id = objcat.Category_Id,
subCategoriesList = (from objSubcat in db.bp_subcategory
where objcat.Category_Id == objSubcat.categoryId
select new subCategory
{
Subcategory_Name = objSubcat.Subcategory_Name,
Subcategory_Id = objSubcat.Subcategory_Id,
Subcategory_Code = objSubcat.Subcategory_Code
})
});
categoryList = Categories.AsEnumerable().ToList();
}
return new VendorRegistrationStep3List{ categoriesList = categoryList };---------Getting Error here
}
View:
<div id="repeater">
@model IEnumerable<AT.Site.BidPortal.Models.VendorRegistrationStep3List>
@foreach (var id in Model)
{
<table>
<tr>
<td width="50">
<input type="image" src="../../Images/Expander.png" size="16px" />
@*<asp:ImageButton ID="PluseBT" runat="server" ImageUrl="~/App_Images/Expander.png"
CommandArgument='<%#Eval("Category_Id") %>' Visible="true" Height="16px" CommandName="_Show"
OnClick="PlusBT_OnClick" />*@
</td>
<td width="350">
