ASP.NET Website - .cs file cannot read the labels from .aspx file

I appreciate this is a common occurrence, however I've tried some of the solutions and none of worked thus far. My project is a 'Web Site' within Visual Studio, thus I don't have the option to 'Right Click and Crete new application'.

The labelID names from my aspx file cannot be read in the corresponding .cs file - flags up with syntax errors.

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>

    </head>


<body>


    <form id="form1" runat="server">
        <asp:TextBox ID="txtCity" runat="server" Text=""  />
        <asp:Button Text="Get Weather Forecast" runat="server" OnClick="GetWeatherInfo" Width="207px" />
        <hr />
        <asp:Repeater ID="Repeater_weatherReports" runat="server">
            <ItemTemplate>
                <table id="tblWeather" runat="server" border="0" visible="false">
                    <tr>
                        <th>
                            Weather Info
                        </th>
                    </tr>
                    <tr>
                        <td>
                            <asp:Label runat="server" ID="lblCity_Country" Text='<%# Eval("city.name") %>' />&nbsp;
                            humidity:<asp:Label runat="server" ID="Label_humidity" Text='<%# Eval("main.humidity") %>' />
                        </td>
                    </tr>
                    <tr>
                        <td>
                            min:<asp:Label runat="server" ID="Label_min" Text='<%# Eval("main.temp_min") %>' />
                            max:<asp:Label runat="server" ID="Label_max" Text='<%# Eval("main.temp_max") %>' />
                        </td>
                    </tr>
                </table>
            </ItemTemplate>
        </asp:Repeater>


    </form>
</body>
</html>

A strange thing is, I can't even see the labelIDs if I click on the 'Design' view. See screenshot. Am I supposed to see the labelIDs here?

enter image description here

Any help will be much appreciated, Thanks

Edit - heres my c# code. Must I loop over RepeatItems somehow?

WeatherInfo weatherinfo = serializer.Deserialize<WeatherInfo>(json);

Repeater_weatherReports.DataSource = weatherinfo.list;
Repeater_weatherReports.DataBind();




int i = 0;
foreach (List list in weatherinfo.list)
{




    lblCity_Country = weatherinfo.city.name;
    //lblDescription.Text = weatherinfo.list[0].weather[0].description;


    Label_min = string.Format("{0}", Math.Round(weatherinfo.list[i].main.temp_min, 1));
    Label_max = string.Format("{0}", Math.Round(weatherinfo.list[i].main.temp_max, 1));
    Label_humidity = weatherinfo.list[i].main.humidity.ToString();
    tblWeather.Visible = true;



    i++;
}

For starters, you can mark table visible="true". Then, you will be able to see the repeater atleast in design view.

protected void Repeater_weatherReports_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
RepeaterItem item = e.Item;
if (item.ItemType == ListItemType.AlternatingItem || item.ItemType == ListItemType.Item)
{
Label lblmin = (Label)item.FindControl("Label_min");
Label lblmax = (Label)item.FindControl("Label_max");
//.........and you can set of get values here.
}
}

In your aspx page, in the line where asp:Repeater is defined, you can add OnItemDataBound="Repeater_weatherReports_ItemDataBound", it will start working.

You can not access direct to label that is inside of repeater or gridview or other data binding controls. You can use events of repeater to access them. e.x:

<asp:repeater onitemcreated="methodnameToCall1" onitemdatabind="methodnameToCall2" >

and find labels by findcontrol method in c#:

void methodnameToCall1(object s,typeofitemcreatedEventsArgs e){

if(e.itemtype == dataitemtype){
var lbl = e.item.findcontrol("lblId") as Label;

}
}

It is semi code, because wrote in stack android app! Excuseme!
