I have a page with three repeater controls on it.  Each one has a label that displays an aggregate number in a label within the footer column.  I've written a function determines which repeater is being rendered and should populate the label with the appropriate value but it's bombing out.  I can't figure out what to put in the switch statement (I tried to use sender.id), so that the right label will be chosen.  Should be an easy one:

    protected void Repeater_ItemCreated(object sender, RepeaterItemEventArgs e)
    {
        if ((mTotalRecords != 0) && (e.Item.ItemType == ListItemType.Footer))
        {
            string sName = sender;

            Label lblTotal;

            switch (sName.ToString())
            {
                 
                case "rptBB":
                    lblTotal = (Label)e.Item.FindControl("lblBBTotal");
                    break;
                case "rptPhone":
                    lblTotal = (Label)e.Item.FindControl("lblPhoneTotal");
                    break;
                case "rptWWAN":
                    lblTotal = (Label)e.Item.FindControl("lblWWANTotal");
                    break;
            }

            lblTotal.Text = "Total: " + mTotalRecords;
        }
     }

The sender parameter is going to be of type Repeater, so you should change the line that says:

string sName = sender;

to something like:

Repeater repCtl = (Repeater) sender;

Then, in the switch statement, you query it's ID:

switch (sName.ID)

which will let you decide which one of the 3 was the sender.

That got it about halfway there.  Here is the updated code:

    protected void Repeater_ItemCreated(object sender, RepeaterItemEventArgs e)
    {
        if ((mTotalRecords != 0) && (e.Item.ItemType == ListItemType.Footer))
        {
            Label lblTotal;
            Repeater repCtl = (Repeater)sender;
            string sName = repCtl.ID.ToString();

            switch (sName)
            {
                 
                case "rptBB":
                    lblTotal = (Label)e.Item.FindControl("lblBBTotal");
                    break;
                case "rptPhone":
                    lblTotal = (Label)e.Item.FindControl("lblPhoneTotal");
                    break;
                case "rptWWAN":
                    lblTotal = (Label)e.Item.FindControl("lblWWANTotal");
                    break;
            }

            lblTotal.Text = "Total: " + mTotalRecords;
        }
     }

It's erroring out here:
"Use of unassigned local variable 'lblTotal'"
Line 122:            lblTotal.Text = "Total: " + mTotalRecords;

I put a breakpoint in the procedure and the id is showing up in each iteration, not sure why it's ending up unassigned.

Forgot to add:

Label lblTotal = new Label();


Thanks dmag, that was a stumper.

Actually, declaring the label as a New Label will get you past the error, but is it working?
I mean, you're creating a new label, instead of modifying the existing one (the one you should be finding through FindControl)

It seems to me that FindControl is returning null (because it can't find the control) or the ID of your sender is not in one of the 3 cases you are expecting, and so it doesn't get assigned.

These are the things I can think about, but I may be missing something.

It's working.  The sender was always one of the three cases so I guess I just needed to initialize the label control.  Thanks again.
