Question

Scenario:

• UsrControl: custom user control, which contains a textbox and a button, rederend horizontally (in one line).

• UsrControlContainer: custom user control, which should be able to display multiple UsrControl objects (each object in seperate line, so the Seperator template will probably be <br />. This control also contains a button, which adds new UsrControl to the collection.

My code:

<asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click"/>
<asp:Repeater ID="rptExample" runat="server">
    <ItemTemplate>

    </ItemTemplate>
    <SeparatorTemplate><br /></SeparatorTemplate>
</asp:Repeater>

And:

protected void Button1_Click(object sender, EventArgs e)
{
    rptExample.DataSource = new List<UsrControl> {new UsrControl(), new UsrControl()};
    rptExample.DataBind();
}

Simple question – what should I put in ItemTemplate to make this work?

Edit – I also want to pass some parameters to UsrControl before rendering it.

Answer 1

<asp:Repeater ID="rptExample" runat="server">
     <ItemTemplate>
          <uc:UsrControl runat="server" />
     </ItemTemplate>
     <SeparatorTemplate><br /></SeparatorTemplate>
</asp:Repeater>

protected void Button1_Click(object sender, EventArgs e)
{
    rptExample.DataSource = Enumerable.Range(0, 2);
    rptExample.DataBind();
}
