Hey guys, I've been helping a buddy of mine trying to figure out this problem with his asp.net site, basically from the admin panel you add a product and it will make the page not work, but if you delete it, it'll work fine, heres the code coming back.

Line 38:                 ((HtmlGenericControl)e.Item.FindControl("divPanel")).Attributes["class"] = "product_panel right_col";
Line 39: 
Line 40:             ((HtmlGenericControl)e.Item.FindControl("divRating")).Style["width"] = (int.Parse(drv["OurRating"].ToString()) * 15).ToString() + "px";

Line 41:
Line 42:             string avail = "";

I'm not understanding the problem, I dont know much asp.net, so be easy on me..

Heres the Stack Trace;

What is the value of drv["OurRating"] when that exception occurs? Interestingly enough I have never seen System.Number.StringToNumber fail before when parsing values so I looked around and it seems there is an odd bug.

Thanks Michael, we now understand this bug, I'm restating it here in case someone else searches for this bug.

As you stated, the problem is that the HKEY_CURRENT_USER\Control Panel\International\sPositiveSign in the registry is completely empty. Editing this and changing it to an empty string solves the problem.

We're still trying to figure out how this got to be missing.

        foreach (GridViewRow gr in GridView1.Rows)
        {
            string tmp = ((Label)gr.Cells[3].FindControl("boekAantal")).Text;
            price += float.Parse(gr.Cells[2].Text) * float.Parse(tmp);
        }
        total.Text = price.ToString();
    }
