[c#] Binding a generic list to a repeater - ASP.NET

I am trying to bind a List<AreaField> to a repeater. I have converted the list into an array by using the ToArray() method and now have a array of AreaField[]

Here's my class hierarchy

public class AreaFields
{
    public List<Fields> Fields { set; get; }
}

public class Fields
{
    public string Name { set; get; }
    public string Value {set; get; }
}

In the aspx, I would like to bind it a repeater (something like this)

DataBinder.Eval(Container.DataItem, "MyAreaFieldName1")

The MyAreaFieldName1 is the value of the Name property in the AreaFieldItem class.

The answer is


You should use ToList() method. (Don't forget about System.Linq namespace)

ex.:

IList<Model> models = Builder<Model>.CreateListOfSize(10).Build();
List<Model> lstMOdels = models.ToList();

It is surprisingly simple...

Code behind:

// Here's your object that you'll create a list of
private class Products
{
    public string ProductName { get; set; }
    public string ProductDescription { get; set; }
    public string ProductPrice { get; set; }
}

// Here you pass in the List of Products
private void BindItemsInCart(List<Products> ListOfSelectedProducts)
{   
    // The the LIST as the DataSource
    this.rptItemsInCart.DataSource = ListOfSelectedProducts;

    // Then bind the repeater
    // The public properties become the columns of your repeater
    this.rptItemsInCart.DataBind();
}

ASPX code:

<asp:Repeater ID="rptItemsInCart" runat="server">
  <HeaderTemplate>
    <table>
      <thead>
        <tr>
            <th>Product Name</th>
            <th>Product Description</th>
            <th>Product Price</th>
        </tr>
      </thead>
      <tbody>
  </HeaderTemplate>
  <ItemTemplate>
    <tr>
      <td><%# Eval("ProductName") %></td>
      <td><%# Eval("ProductDescription")%></td>
      <td><%# Eval("ProductPrice")%></td>
    </tr>
  </ItemTemplate>
  <FooterTemplate>
    </tbody>
    </table>
  </FooterTemplate>
</asp:Repeater>

I hope this helps!

public class Friends
{
    public string   ID      { get; set; }
    public string   Name    { get; set; }
    public string   Image   { get; set; }
}

protected void Page_Load(object sender, EventArgs e)
{
        List <Friends> friendsList = new List<Friends>();

        foreach (var friend  in friendz)
        {
            friendsList.Add(
                new Friends { ID = friend.id, Name = friend.name }    
            );

        }

        this.rptFriends.DataSource = friendsList;
        this.rptFriends.DataBind();
}
