How to properly escape a double quote in the `eval` function

I am facing an issue with a link button in a gridview as shown below

<asp:LinkButton ID="lbtnEdit" runat="server" OnClientClick='<%# String.Format("Edit(\"{0}\", \"{1}\");return false;",Eval("Comment").ToString(),Eval("Status")) %>' >Edit</asp:LinkButton>

Everything works fine except when there are double quotes in the comment field. I tried changing it to Eval("Comment").ToString().Replace(/'/g, "\'") but unfortunately I received an error stating "The server tag is not well formed."

If anyone has any suggestions or solutions for this issue, please let me know.

Answer №1

The substitution you attempted employs JavaScript. Due to the presence of embedded quotes on the HTML page, JavaScript no longer considers it as a complete string. To rectify this issue, utilize the .NET adaptation of the replacement function to encode the data on the server side:

For Visual Basic (VB), here is an example:

Eval("Comment").ToString().Replace("""", "\""")

This code snippet will substitute all quotation marks within the comment with escaped equivalents, preventing any unintended closure or initiation of new strings.
