How are you encrypting the string? can you show your code?

Encoding

public static string Base64EncodingMethod(string sData)
{

byte[] encodingDataASBytes = System.Text.Encoding.Unicode.GetBytes(sData);

string sReturnValues = System.Convert.ToBase64String(encodingDataASBytes);

return sReturnValues;

}

TextBox1.Text = Base64EncodingMethod(clientcode.ToString());
Application["clientcode"] = TextBox1.Text;

Decoding

public static string Base64DecodingMethod(string sData)
{

byte[] encData = System.Convert.FromBase64String(sData);
string result = System.Text.ASCIIEncoding.ASCII.GetString(encData);
return result;
}

txtclientcode.Text = Request.QueryString["clientcode"];
TextBox1.Text = Base64DecodingMethod(txtclientcode.Text.ToString());

Re write your method following way...

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
