What is the syntax to concatenate text into a binding expression for an asp.net webpage (aspx).
For example if I had a hyperlink that was being bound like this:
<asp:HyperLink id="lnkID" NavigateUrl='<%# Bind("Link") %>' Target="_blank"
Text="View" runat="server"/>
How do you change, say, the Text to concatenate a bound value with a string? Variations like this aren't quite right.
Text='<%# Bind("ID") + " View" %>'
neither does
Text='<%# String.Concat(Bind("ID"), " View") %>'
You concatenate strings by using the + operator. For string literals and string constants, concatenation occurs at compile time; no run-time concatenation occurs. For string variables, concatenation occurs only at run time.
In PowerShell, string concatenation is primarily achieved by using the “+” operator. There are also other ways like enclosing the strings inside double quotes, using a join operator, or using the -f operator. $str1="My name is vignesh."
The term 'data binding in ASP.NET simply means that the data that is collected from a source is bound to the controls that provide the read and write connection to the data. Databases, XML files, flat files, etc are some of the data sources we are talking about here.
Use Eval instead.
Text='<%# Eval("ID", "{0} View") %>'
Eval is also better if the value is not going to be updated, where Bind allows two way data binding.
