    <p>I'm new to programming and using <code>SQL Server Compact</code> and I'm doing this personal project to learn, so any assistance is greatly appreciated. </p> <p>I am trying to hide the <code>button</code> in the <code>Main Form</code> depending on the user type account that successfully logging.</p> <p>In my database i have 3 columns which are <code>username</code>, <code>password</code> and <code>type - (this is what I am trying to access for this project)</code>.</p> <p>I figured that to get the effect that I want I would have to deal with the Main_load so this is where I placed this code:</p> <pre><code> private void Main_Load(object sender, EventArgs e) { admincontrolbtn.Visible = false; conn = new SqlCeConnection("Data Source=Users.sdf; Persist Security Info = False"); comm = new SqlCeCommand("Select * from [user]", conn); reader = comm.ExecuteReader(); while (reader.Read()) { try { conn.Open(); if (reader.GetString(2) == "Administrator") { admincontrolbtn.Visible = true; } else { admincontrolbtn.Visible = false; } } catch (Exception ex) { MessageBox.Show(ex.ToString()); } finally { conn.Close(); } } } </code></pre> <p>When I built the code no error was found. I thought that I was on the right track. But when I logged in using a credential that has a <code>User" type</code>, the <code>button</code> was still visible. I have already tried to debug the code by putting a break right on the <code>Main_load</code> itself but when i run it and log in, it goes to display the Main page ignoring the Main_load altogether. </p> <p>I have also tried to set the visibility of the <code>button</code> to false it the properties but when the main page loads, even using the <b>Administrator</b> type of credential, the <code>button</code> stays hidden.</p> <p>Was the syntax of the code wrong? and/or maybe my way of thinking that <code>Main_load</code> is my target wrong?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
