Error on input string format not correct

I have this simple calculation but for some reason I am not picking up where the problem is. I am getting "format input string not correct" error.

This is the code:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
    {
        GridDataItem dataItem = e.Item as GridDataItem;
        if (dataItem["AlternCost"].Text !=null)
        {
            dataItem["TotCost"].Text = ((Convert.ToInt32(dataItem["AlternCost"].Text)) * (Convert.ToDouble(dataItem["Quantity"].Text))).ToString();
        }
        else
        {
            dataItem["TotCost"].Text = ((Convert.ToInt32(dataItem["Cost"].Text)) * (Convert.ToDouble(dataItem["Quantity"].Text))).ToString();
        }
    }
}

The error is on this line:

dataItem["TotCost"].Text =
((Convert.ToInt32(dataItem["AlternCost"].Text)) *
(Convert.ToDouble(dataItem["Quantity"].Text))).ToString();

This is my stack trace:

Can someone please give me a hint on how to solve the problem?

Shouldn't this be:

dataItem["TotCost"].Text = ((Convert.ToDouble(dataItem["AlternCost"].Text)) * (Convert.ToDouble(dataItem["Quantity"].Text))).ToString();

intead of:

dataItem["TotCost"].Text = ((Convert.ToInt32(dataItem["AlternCost"].Text)) * (Convert.ToDouble(dataItem["Quantity"].Text))).ToString();

note the Convert.ToDouble in both cases instead of ToInt32 and ToDouble?
