How to pass special characters through query string ?

[Sobin Thomas]

Hi All,
I want to pass a string that contains many special characters \ . _
etc) to another page in my website
through query string.
In my project I have a Gridview control ,in which there is a hyperlink
field.The Gridview 's datasource is set as a database table at runtime.The
hyperlink filed's DataNavigateUrlFields is set to "RecordID" ,which is a
field in my database table.The RecordID field contains many special
characters.I want to pass the RecordID to PlayRecord.aspx page .I transfer
the RecordID by setting Hyperlink field's Data NavigateUrlFormat string as
PlayRecord.aspx?RecID={0}.The problem is that, hyperlinks are not working as
RecordID contains special characters.(It works if RecordID is a normal
string).
Hope you 'll surely have a solution.
Thanking you in advance for your reply.
Best Regards

This group is for Classic ASP. For ASP.NET questions post to
microsoft.public.dotnet.framework.aspnet

The solution is the same for dotnet as it is for COM-based ASP: use the
urlEncode method to encode the strings being put into the querystring.
Having said that:

There was no way for you to know it (except maybe by browsing through some
of the previous questions in this newsgroup before posting yours - always a
recommended practice) , but this is a classic (COM-based) asp newsgroup.
ASP.Net bears
very little resemblance to classic ASP so, while you may be lucky enough to
find a dotnet-knowledgeable person here who can answer your question, you
can eliminate the luck factor by posting your question to a group where
those dotnet-knowledgeable people hang out. I suggest
microsoft.public.dotnet.framework.aspnet or the forums at www.asp.net.

How easy is that to achieve when databinding into a gridview? I don't use
the provided controls much myself. I suspect one would need to add a field
to the datasource that has the value UrlEncoded. Better would be to not use
such a value and use a numeric, hash or guid instead.

I hadn't really thought it through. I suppose he would have to use a
templatefield object rather than a boundfield object so the object can
be bound to the result of the UrlEncode function.

That's one of the options I was thinking of.

I can't argue with that.

Or you could simply format the value in the control's RowDataBound event....
