How to concatenate static 开发者_如何转开发text in the start of Eval("") in asp.net?

For concating two fields from db you can use string.Concat function in eval()

 Text='<%# string.Concat(Eval("FirstName"), " ", Eval("LastName"))%>'

try this: Text='<%# string.Concat("Table No:", " ", Eval("table_no")) %>'

This works fine for me:

<%#Class.something.ToString() & Eval("something_to_eval")%>

Doing this (without single quote) worked for me. And Visual Studio underlines it as a Validation warning.

 onclick=<%# "modCbClick('#tbl_" + Eval("ModCode") + "', this)" %>

Append string to end

CommandArgument='<%# String.Format(string.Concat(Eval("DBValue"), "TextString"))%>'
