Querystring encoding issue

Question

I am facing one problem while storing a querystring value in a variable. My url is something like shown below:

http://localhost:1372/testapp/default.aspx?Search=%family%

Below is what I tried:

string result = Request.QueryString["Search"].ToString();

When I tried to save the querystring search in variable its taking value as �mily% .

How can I get value of search parameter as family?

Thanks in advance.

Where does that query string come from? It is clearly wrong ... you need to UrlEncode the parameter. — Wolfgang Ziegler

The query string parameters have to get URL-encoded. The problem ist th % character which is used for URL encoding, so it has to get encoded itself.

'%' becomes '%25'

Which means, the whole URL becomes:

http://localhost:1372/testapp/default.aspx?Search=%25family%25

your can use HttpUtitlity.UrlEncode

In Parent Page Encode query string this way

public static sting Encode(string sData)
{
return HttpUtility.UrlEncode(sData);
}

Now pass this encoded query string to your parent page & on Parent page decode that query string by following function. I assume that encoded query string name is sData & its passed from parent page to child page

public static string Decode()
{
string dSData = HttpUtility.UrlDecode(Request.QueryString["sData"].ToString());
return dsData;
}

I think you have idea about how to pass query string from parent to child page
