I want to access label value in code behind page

I want to access label value in code behind page.

int a = int.Parse(Label5.Text);
if (a <= 10)
{
    Label5.BackColor = System.Drawing.Color.Red;
}

<asp:Label CssClass="txtStock" ID="Label5" runat="server" Text='<%# Eval("Pquant") %>'></asp:Label>

I'm not able to access Label5 in code behind page as it doesn't exist. I want to fetch Label5 value and store it in a variable. Label5 is taken inside datalist control

You can't access Label5 in codebehind because it's part of a datacontrol like FormView, GridView, Repeater or someting. So this Label doesn't exist only once - it exists in every item of your data control.

If you want to set your BackColor dynamicly you can do it in the Databinding method (e.g. GridView) 

protected void YourGridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        Label Label5 = (Label)e.Row.FindControl("Label5");
        if (int.Parse(Label5.Text) <= 10)
        {
            Label5.BackColor = System.Drawing.Color.Red;
        }
    }
}

or do directly in the Label:

<asp:Label CssClass="txtStock" ID="Label5" runat="server" Text='<%# Eval("Pquant") %>'
BackColor='<%# int.Parse(Eval("Pquant")) <= 10 ? System.Drawing.Color.Red : System.Drawing.Color.Black %>' 
></asp:Label>
