Finding subtotal for column in repeater control

I hope this helps . Declare the variable outside of the ItemDataBound event. The problem with your code is that ItemDataBound event is called after every row is bound to the repeater control, so every time your subtotal & price are getting initialized to 0 thus you are not getting the expected output.
double subtotal = 0;
double price = 0;

protected void rptItem_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
    if (e.Item.ItemType == ListItemType.Item)
    {
        price += Convert.ToDouble(DataBinder.Eval(e.Item.DataItem, "Price"));
        subtotal += price;
    }

    if (e.Item.ItemType == ListItemType.Footer)
    {
        Label lblSubtotal = (Label)e.Item.FindControl("lblSubtotal");
        lblSubtotal.Text = subtotal.ToString();
    }
}

HIde a Column in Repeater Control

Hope this helps Label1 is a Label control and not Repeater, that's why you're getting an error
You also need to add an if condition so you only get the Label1 for items and not for header or footer.
if (e.Item.ItemType == ListItemType.Item || 
    e.Item.ItemType == ListItemType.AlternatingItem)
{
    Label label = (Label)e.Item.FindControl("Label1");
    label.Visible = false;
}

should help you out Use FindControl to get the nested control in the rptSpecialNotes_Item event handler - this will return the control:
sender.FindControl("specialNotes")

Hope that helps A Repeater is actually considered as a read-only control.
It is one of the simplest built-in data-bound controls.

To fix this issue Look at the below picture I want to count value of last column (cnt) I am using repeater control. , You could do something like:
protected void CloudTags_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
    var repeaterItem = e.Item;
    // TODO you still have to check the type of the repeaterItem
    var dataItem = (dynamic) repeaterItem.DataItem;
    var cnt = dataItem.cnt;
    if (cnt > 5)
    {
        var hyperLink = (HyperLink) repeaterItem.FindControl("HyperLink9");
        hyperLink.CssClass = "TagSize2";
    }
}
protected void CloudTags_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
    var repeaterItem = e.Item;
    // TODO you still have to check the type of the repeaterItem
    var dataItem = repeaterItem.DataItem;
    var objCnt = DataBinder.Eval(dataItem, "cnt");
    // TODO check the whole parsing/converting stuff ...
    var stringCnt = objCnt.toString();
    var cnt = int.Parse(stringCnt);
    if (cnt > 5)
    {
        var hyperLink = (HyperLink) repeaterItem.FindControl("HyperLink9");
        hyperLink.CssClass = "TagSize2";
    }
}
