Repeater and DataView

Good morning all,

How will I display Dataview's datarows as Parent and child format in the repeater?

Cheers,
Dummy

I usually use a nested repeater:

PHP Code:

---

public class YourPage : Page
{
  private DataTable _parentsAndChildren;
  protected Repeater rptrParents;
  protected override void OnLoad(System.EventArgs e)
  {
    if(!Page.IsPostBack) bindData();
  }
  private void bindData()
  {
    //code to fill up _parentsAndChildren with data goes here.
    DataView parents = new DataView(_parentsAndChildren);
    parents.RowFilter = "ParentID = ChildID";
    rptrParents.DataSource = parents;
    rptrParents.DataBind();
  }
  protected DataView GetChildren(object dataItem)
  {
    DataView children = null;
    DataRowView parentRow = dataItem as DataRowView;
    if(parentRow != null)
    {
      string rowFilter = "ParentID<>ChildID and ParentID=" 
        + parentRow["ParentID"].ToString();
      children = new DataView(_parentsAndChildren);
      children.RowFilter = rowFilter;
    }
    return children;
  }
}

the repeater on the aspx page would look something like this:

Code:

---

<asp:Repeater ID="rptrParents" Runat="server">
  <HeaderTemplate>
    <table>
      <tr>
        <td>Name</td>
      </tr>
  </HeaderTemplate>
  <ItemTemplate>
    <tr>
      <td>
        <%# DataBinder.Eval(Container.DataItem, "Name") %>
      </td>
    </tr>
    <!-- Now get the children for the current parent -->
    <asp:Repeater ID="rptrChildren" Runat="server"
      DataSource='<%# GetChildren(Container.DataItem) %>'>
      <ItemTemplate>
        <tr>
          <td>
            <%# DataBinder.Eval(Container.DataItem, "Name") %>
          </td>
        </tr>
      </ItemTemplate>
    </asp:Repeater>
  </ItemTemplate>
  <FooterTemplate>
    </table>
  </FooterTemplate>
</asp:Repeater>
