Question

Lets say I have the following:

<asp:Repeater ID="repSubItems" runat="server" DataSource="<%# SubItems %>" >
    <ItemTemplate>
        <sc:FieldRenderer ID="FieldRenderer1" 
            FieldName="BlurbSpot_Content_SubHeading" 
            runat="server" 
            Item="<%# Container.DataItem as Sitecore.Data.Items.Item %>" />  
    </ItemTemplate>
</asp:Repeater>

I want to in code behind be able to do:

FieldRenderer1.Style["Width"] = MyCoolWidth;

But within the Repeater I cannot access the FieldRenderer1 control.

You will need to handle the ItemDataBound event of the repSubItems repeater. Example:

protected void repSubItems_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
    if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
    {
        var fieldRenderer1 = e.Item.FindControl("FieldRenderer1") as Sitecore.Web.UI.WebControls.FieldRenderer;
        if (fieldRenderer1 != null)
        {
            fieldRenderer1.Style["Width"] = MyCoolWidth;
        }

    }
}
