Hi,

Anyone know how to add a field to a widget template so that it pulls only the first few characters of the field? For example, we have a custom module that has Questions and Answers. I want to the master view to have a list of the questions with the first part of the answer.

I tried

<asp:Label ID="Label1" runat="server" Text='<%# Eval("Answer").ToString().Substring(0,Math.Min(150,Eval("Answer").ToString().Length)) + "…" %>'></asp:Label>

But the field has HTML in it and it's causing formatting issues.

Sitefinity has an extension method to truncate

Class is SitefinityExtensions

public static string TruncateString(this string valueToTruncate, int maxLength, SitefinityExtensions.TruncateOptions options)

So like Eval("Answer").ToString().TruncateString(100, SitefinityExtensions.TruncateOptions.IncludeEllipsis)

That's exactly what I needed. Thanks so much Steve!

Np, FYI...truncateoptions has 4 modes...I think they can stack (marked as flags)

None
FinishWord
AllowLastWordToGoOverMaxLength
IncludeEllipsis
