private void btn_Save_Click(object sender, EventArgs e)
        {     
            
                if (lbl_LibId.Text == "*")
            {
                string sql = "insert into Request (Date, Part_Number, Request_By, Assigned_CC, IC_Analyst, Priority, Comments)" +

                             " values(@Date, @Part_Number, @Request_By, @Assigned_CC, @IC_Analyst, @Priority, @Comments)";

                Request.ExecuteSQL(sql, new[] {

                        new SQLiteParameter("@Date", dateTimePicker1.Text),
                        new SQLiteParameter("@Part_Number", txt_Part_Number.Text),
                        new SQLiteParameter("@Request_By", txt_Count_Request_By.Text),
                        new SQLiteParameter("@Assigned_CC", txt_Assigned_Code.Text),
                        new SQLiteParameter("@IC_Analyst", txt_Analyst.Text),
                        new SQLiteParameter("@Priority", cb_Priority.Text),                       
                        new SQLiteParameter("@Comments", txt_Comments.Text),                         
                        
                    });
                

                DataBind();

We can't tell: we don't have access to your database or your code while it is running.

If the DTP value is being inserted, then all the value are - so either every other control is empty, or that code isn't being executed at all. And we can't help you find out which.

So, it's going to be up to you.
Fortunately, you have a tool available to you which will help you find out what is going on: the debugger. If you don't know how to use it then a quick Google for "Visual Studio debugger" should give you the info you need.

Put a breakpoint on the first line in the function, and run your code through the debugger. Then look at your code, and at your data and work out what should happen manually. Then single step each line checking that what you expected to happen is exactly what did. When it isn't, that's when you have a problem, and you can back-track (or run it again and look more closely) to find out why.

Sorry, but we can't do that for you - time for you to learn a new (and very, very useful) skill: debugging!

Please tell me you're not saving DateTime values as strings in the database...

Without knowing the structure (datatypes of the columns) of the table you're trying to save to, it's impossible for anyone to tell you what's going on.

But, I'll tell you this. The constructor of the SqlParameter class you're using will treat every piece of information you're passing to them as strings, since that is what you're passing to every instance of SqlParameter.

What does that mean? Well, if a column in your table is an INT or other non-VARCHAR type, you're attempting to to put a string into a column that cannot hold it.

"100" and 100 are NOT the same value type! One is a string, and the other is an integer. Chances are pretty good you're trying to save "100" (a string) in a column with a type of INT. That's not going to work.
