I got a web application, the problem is that the text in the label will not update on the first click, I need to click the button twice, I debugged to code, and I found out that the label does not recive the data until after the second click,

Here is my code:

```
System.Data.SqlClient.SqlCommand command = new System.Data.SqlClient.SqlCommand();
System.Data.SqlClient.SqlConnection connection;
string CommandText;
string game;
string modtype;
bool filter;
protected void Page_Load(object sender, EventArgs e)
{

    labDownloadList.Text = null;

    //Session variables:
    if (Session["Game"] != null)
    {
        game = Convert.ToString(Session["Game"]);
    }
    if (Session["ModType"] != null)
    {
        modtype = Convert.ToString(Session["ModType"]);
    }
    if (Session["FilterBool"] != null)
    {
        filter = Convert.ToBoolean(Session["FilterBool"]);
    }
    string ConnectionString = "Data Source=.\\SQLEXPRESS;AttachDbFilename=C:\\inetpub\\wwwroot\\stian\\App_Data\\Database.mdf;Integrated Security=True;User Instance=True";
    connection = new System.Data.SqlClient.SqlConnection(ConnectionString);
    System.Data.SqlClient.SqlDataReader reader;
    command = connection.CreateCommand();
    connection.Open();
    CommandText = "SELECT * FROM Command";
    if (filter)
    {
        CommandText = "SELECT * FROM Command WHERE Game='" + game + "' AND Type='" + modtype + "'";
    }
    command.CommandText = CommandText;
    reader = command.ExecuteReader();
    labDownloadList.Text = "";
    while (reader.Read())
    {
        string game = reader.GetString(1);
        string author = reader.GetString(2);
        string downloadlink = reader.GetString(3);
        string size = reader.GetString(4);
        string description = reader.GetString(5);
        string version = reader.GetString(6);
        string screenshotlink = reader.GetString(7);
        Int64 AmountDownloaded = reader.GetInt64(8);

        labDownloadList.Text += "Game: " + game + "<br>";
        labDownloadList.Text += "Author: " + author + "<br>";
        labDownloadList.Text += "Size: " + size + "<br>";
        labDownloadList.Text += "Description: " + description + "<br>";
        labDownloadList.Text += "Version: " + version + "<br>";
        labDownloadList.Text += "<img src='" + screenshotlink + " /><br>";
        labDownloadList.Text += "Downloaded: " + AmountDownloaded + " times<br><hr>";
        labDownloadList.Text += "<a href='" + downloadlink + "'>Download</a><br>";
    }
}

protected void Page_UnLoad(object sender, EventArgs e)
{
    Session["Game"] = game;
    Session["ModType"] = modtype;
    Session["FilterBool"] = filter;
    connection.Close();
}

protected void btnFilter_Click(object sender, EventArgs e)
{
    game = lstGames.SelectedValue;
    modtype = lstTypeMod.SelectedValue;
    filter = true;
}

```
