Advice on label text concatenation during databinding

[GM]

I am building the text for a resume section label in databinding with 20 or
so data columns using a series of 20 or so code snippits like the following:

If e.Item.DataItem("EmployerDisplay") And e.Item.DataItem("Employer") <> ""
Then
Sections.Text += "<BR><B>Employer</B>: " & e.Item.DataItem("Employer")
End If

Is this an efficient way to build the section label's text property? Any
suggestions?

In each snippit, I call the data field twice, once to test for data and once
to add it to the control if present. Would it be better to pull the data
into a string or something?

Dim ds as String
------
ds = e.Item.DataItem("Employer")
If e.Item.DataItem("EmployerDisplay") And ds <> "" Then
Sections.Text += "<BR><B>Employer</B>: " & ds
End If

Thanks in advance for any suggestions.

You can use the StringBuilder object from the System.Text namespace - its
built specifically for concatenation operations.

It is much more efficient to use your proposed approach: ds =
e.Item.DataItem("Employer")
than it is to reference the chain of objects more than once.

You can use a StringBuilder or String.Concat to do this efficiently, but I
wouldn't recommend constantly appending to the Label control directly.

I thought about the StringBuilder, but I don't know how the Label control
compares.

Is the text property of the Label control built to work well with
concatenation too? Or should I builld all the resume sections in a
StringBuilder and then assign it to the Section Label's text property at the end?

Or, are you suggesting it is better to store the data value in each code
snippet in a StringBuilder (or String) rather than call it twice?

Thanks
