Using the best answer from this question, I could successfully submit a login form and get an authenticated webpage using WebClient:

    var loginCredentials = new NameValueCollection
    {
        { "username", "user123" },
        { "password", "pass321" },
    };

    client.UploadValues(
        @"http://www.mywebsite.com/User/Login?ReturnUrl=" +
        @"http://www.mywebsite.com/Tickets/Search", loginCredentials);

However, when I try submitting another form to search for specific filters (one is a "dropdown" element and the other is an "option" element) on the resulting webpage, I get a webexception on the method UploadValues:

    var jitbitSearch = new NameValueCollection
    {
        { "fromUserId_username", "447" },
        { "statusId", "-3" },
    };

    try
    {
        client.UploadValues(
        @"http://www.mywebsite.com/Tickets/Search", jitbitSearch);
    }
    catch {}

    string result = client.DownloadString("http://www.mywebsite.com/Tickets/Search");
    textBox1.Text = result;

HTML output of fromUserId_username (dropdown):

    <td><script type='text/javascript' src='/js/jquery.autocomplete.js'></script>   <input type="text" id="fromUserId_username" name="fromUserId_username" value="" placeholder="Email or user" />
<input type="hidden" id="fromUserId" name="fromUserId" value="" />
<script type="text/javascript">
    $(function() {
        InitUserBox('fromUserId', "");
    });
</script>

HTML output of statusId (select option):

<td>Status:</td>
<td><select name="statusId">
        <option value=""></option>
                <option value="10"  >Undergoing</option>
                <option value="5"  >Under analysis</option>
                <option value="2"  >Pending</option>
                <option value="6"  >On hold</option>
                <option value="3"  >Closed</option>
                <option value="1"  >Under testing</option>
                <option value="4"  >New</option>
                <option value="7"  >Under development</option>
                <option value="8"  >Recurring</option>
            <option value="">--------</option>
                <option value="-10"  style="color:#CC6666;">(not) Undergoing</option>
                <option value="-5"  style="color:#CC6666;">(not) Under analysis</option>
                <option value="-2"  style="color:#CC6666;">(not) Pending</option>
                <option value="-6"  style="color:#CC6666;">(not) On hold</option>
                <option value="-3"  style="color:#CC6666;">(not) Closed</option>
                <option value="-1"  style="color:#CC6666;">(not) Under testing</option>
                <option value="-4"  style="color:#CC6666;">(not) New</option>
                <option value="-7"  style="color:#CC6666;">(not) Under development</option>
                <option value="-8"  style="color:#CC6666;">(not) Recurring</option>
    </select>

Any idea what's causing the exception? Is it because the method UploadValues doesn't support this kind of input? Thanks.

Note: Even if I comment out one of the form inputs, both of them trigger the webexception.

EDIT: The exception I'm getting is the following: "The remote server returned an error: (500) Internal Server Error".

Answering my question, doing this small change worked for me:

byte[] request = client.UploadValues(@"http://www.mywebsite.com/Tickets/Search", "POST", jitbitSearch);
string req = Encoding.UTF8.GetString(request);
textBox1.Text = req;
