Can't get full value for Request.QueryString

1.

string Id = HttpContext.Current.Request.QueryString["id"];

string Id = HttpContext.Current.Request.QueryString["ID"];//upper id

2.Weather or not your server can get the parameter of the client.



I guess,your url is wrong.
I want to know the routes of the .aspx and the .cs

There are some characters that get encoded when put in URL. Instead of replacing them in Code you should think about putting a

Server.UrlEncode(string);

before putting the data in query strings. and after retrieving do a

Server.UrlDecode(string);

before using it.

Use:

string encodedURL = System.Net.WebUtility.HtmlEncode(e.Row.Cells[0].Text.Trim());

e.Row.Attributes.Add("onclick", "javascript:window.location.href ='AutoPMPage.aspx?ID=" + encodedURL + "';");

And on AutoPMPage.aspx use:

string Id = System.Net.WebUtility.HtmlDecode(HttpContext.Current.Request.QueryString["id"]);

Well if I were you I would use UrlEncoding and UrlDecoding for the pound key.
What I meant by this while passing your ID you should encode it and when you want to use it you should decode it to use it.

You should check the WebUtility Class[^].

Also here is an example link[^]that you can have a look at.

Good luck,
