Hi KaranGupta,
You can use HttpUtility.URLEncode() to encode the passed parameter. Then, read the encoded parameter via HttpUtility.URLDecode()

Hi x_com

I have done that but result is same. I have lost the '+' sign from request.querystring

 

by: x_comPosted on 2009-08-24 at 03:29:26ID: 25166947

I've created a test case and it is displaying the expected result.

private void test(){
        string s;
        string str ;
        str = "bla bla bla bla"

        s = HttpUtility.UrlEncode("http://url.com?P=" & str);
        Response.Write(s);
        Response.Write("<br><br>");
        Response.Write(HttpUtility.UrlDecode(s));
}

Can you post some of your existing applied code and see how to tweak the problem?

Hi

Instead of

str = "bla bla bla bla"

write

str = "bla+ bla+ bla+ bla" and then try

 

by: x_comPosted on 2009-08-24 at 03:38:58ID: 25166995

Hi,

If i use str = "bla+ bla+ bla+ bla",
this is the output:

Input: http%3a%2f%2furl.com%3fP%3dbla%2b+bla%2b+bla%2b+bla
Output: http://url.com?P=bla+ bla+ bla+ bla

It is displaying the initial input as expected for "str" variable. Please provide more details.

Hi

i have a list page. when I click on it, the page navigates to the detail page. Here I am sending the string with value "abc + cde" in querystring. When I am getting the  value from request.querystring then "+" sign vanishes.

Hope I am clear now.
If you need more elaboration then please let me know.

 

by: x_comPosted on 2009-08-24 at 20:51:29ID: 25174457

Hi,
Hmm, that is sound strange. You should able to get the "+" sign if the passed parameter have included that symbol.
Could you post some of your applied code? Let see anything not right there.

 

by: KaranGuptaPosted on 2009-08-25 at 00:37:48ID: 25175207

Hi

Sorry I can't post code . You can try by making a simple application in which you can create 2 webpages.

On webpages you can redirect to second page

for example there are 2 pages Page1.aspx and Page2.aspx.

On page load of the Page1.aspx write this

Response.Redirect("Page2.aspx?test = 'ABC + CDE'")

On Page load of Page2.aspx

see the value of

Request.QueryString("test")

Please let me know if you need more details.

Hi,
Ok, this is so odd. I've tested in vb.net, it is returning the expected using proposed. If you running the code in c# environment, you need to replace "+"  with "%2b". Then, you need to convert the "%2b" into "+" after decode the passed parameter.
eg:
P1.aspx
=========
      Response.Redirect("p2.aspx?test=" + HttpUtility.UrlEncode("ABC CDE".Replace("+","%2b")) );
            
P2.aspx
=========
      Response.Write("P=" + HttpUtility.UrlDecode(Request.QueryString["test"]).ToString().Replace("%2b","+"));

Hi

Instead of "ABC CDE" please write this "ABC + CDE"

 

by: x_comPosted on 2009-08-25 at 01:11:48ID: 25175361

Hi,
You can replace it "ABC+CDE" in my sample. It is running as expected.
eg:
   Response.Redirect("p2.aspx?test=" + HttpUtility.UrlEncode("ABC+CDE".Replace("+","%2b")) );

You need to decode the html content. Depending on whetehr you want to do it in VB code or in SQL:-

SQL - have a look at the decode function shown here - http://www.thedivingclub.co.uk/Information/DNNBlog/tabid/368/articleType/ArticleView/articleId/80/categoryId/5/Whats-New-for-the-members.aspx
VB - you need to use System.Web.HttpUtility.HTMLDecode(objevent.EventDesc)
