>> Type or namespace definition, or end-of-file expected

This error will show when you placed the piece of code in wrong place.
For eg:- If you place this code inside page_load, it will show the same error. Because this is an individual procedure

Verify this

My code actually have the opening & closing brace properly. Are you sure you put it in correct place (not into another procedure /event)

You're either going to need to parse the value, or compare to a string:

if (Convert.ToInt32(DataBinder.Eval(e.Row.DataItem, "alert").ToString()) == 1)
{
    // etc, etc
}

You need to cast

For eg:- Change
if ( DataBinder.Eval(e.Row.DataItem, "alert") == 1)
to
 if (Convert.ToInt32(DataBinder.Eval(e.Row.DataItem, "alert")) == 1)

Of course, you could just cut your code in half and use:

protected void GridView1_RowCreated(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e)
        {
            int alert = Convert.ToInt32(DataBinder.Eval(e.Row.DataItem, "alert").ToString());
            Color backColor = (alert == 1 ? Drawing.Color.Red : Drawing.Color.Orange);

            (e.Row.FindControl("Label2") as Label).BackColor = backColor;
            (e.Row.FindControl("Label2") as Label).ForeColor = Drawing.Color.White;
            (e.Row.FindControl("Label3") as Label).BackColor = backColor;
            (e.Row.FindControl("Label3") as Label).ForeColor = Drawing.Color.White;
            (e.Row.FindControl("Label4") as Label).BackColor = backColor;
            (e.Row.FindControl("Label4") as Label).ForeColor = Drawing.Color.White;
            (e.Row.FindControl("Label5") as Label).BackColor = backColor;
            (e.Row.FindControl("Label5") as Label).ForeColor = Drawing.Color.White;
            (e.Row.FindControl("Label6") as Label).BackColor = backColor;
            (e.Row.FindControl("Label6") as Label).ForeColor = Drawing.Color.White;
            (e.Row.FindControl("Label7") as Label).BackColor = backColor;
            (e.Row.FindControl("Label7") as Label).ForeColor = Drawing.Color.White;
            (e.Row.FindControl("Label8") as Label).BackColor = backColor;

The page now runs but it isnt showing the highlighted rows. I placed a debug catch on the code but it didnt pause on this code at all?

That means the event handler isn't hooked up properly. Switch to design view, select your grid then, in the properties window click the lightning bolt (which is properties). Scroll down till you find RowCreated and then set its value to "GridView1_RowCreated".

OK, that means that either DataItem is null, or it can't find the label.

Odds are it is because it is also firing for the header row, which will not have an associated DataItem. Try wrapping it with an additional "if":

protected void GridMain_RowCreated(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
         if (Convert.ToInt32(DataBinder.Eval(e.Row.DataItem, "alert").ToString()) == 1)
        {  
             (e.Row.FindControl("Label2") as Label).BackColor = System.Drawing.Color.Red;
             ....
        }
    }
}

You'll need to put a breakpoint on the methods that draw your grid and see what is happening. ScriptManager messages are usually a bit vague.

It look slike its happening because on timer event we get a e.Row.DataItem is null is there a way to almost say


coalesce(e.Row.DataItem,0)

or

isnull(e.Row.DataItem,0)
