    <p>I'm trying to code a Windows game using XNA and so far I'm stuck on drawing the menu. Here is my code:</p> <p>Game.cs:</p> <pre><code> protected override void LoadContent() { Text musicLevelText; musicLevelText.textValue = "Music :"; musicLevelText.location = new Vector2(400 - (int)font.MeasureString(musicLevelText.textValue).X - 20, 50); musicLevelText.font = font; Text soundEffectText; soundEffectText.textValue = "Sound Effects :"; soundEffectText.location = new Vector2(400 - (int)font.MeasureString(soundEffectText.textValue).X - 20, 10 + musicLevelText.location.Y + (int) font.MeasureString(musicLevelText.textValue).Y); soundEffectText.font = font; Text languageText; languageText.textValue = "Language :"; languageText.location = new Vector2(400 - (int)font.MeasureString(languageText.textValue).X - 20, 10 + soundEffectText.location.Y + (int)font.MeasureString(soundEffectText.textValue).Y); languageText.font = font; Button backToMainMenuButton = new Button(font, spriteBatch, "Back", new Vector2(20, 440)); optionsMenu = new Menu(new Button[1] {backToMainMenuButton}, new Text [3]{musicLevelText, soundEffectText, languageText}, background, spriteBatch); } </code></pre> <p>Menu.cs :</p> <pre><code>public void Update() { for (int i = 0; i &lt; buttons.Length; i++) { buttons[i].Update(); } } public void Draw() { spriteBatch.Begin(); spriteBatch.Draw(background, new Rectangle(0, 0, 800, 480), Color.White); spriteBatch.End(); if (!menuOn) return; for ( int i = 0; i &lt; buttons.Length; i++){ buttons[i].Clickable = true; } spriteBatch.Begin(); for (int i = 0; i &lt; texts.Length; i++) { spriteBatch.DrawString(texts[i].font, texts[i].textValue, texts[i].location, Color.White); } spriteBatch.End(); } public struct Text { public string textValue; public Vector2 location; public SpriteFont font; } </code></pre> <p>Button.cs :</p> <pre><code> public void Draw() { if (clickable) DrawButton(textRectangle); } private void DrawButton(Rectangle boundaries) { Vector2 size = font.MeasureString(text); float xScale = (boundaries.Width / size.X); float yScale = (boundaries.Height / size.Y); // Taking the smaller scaling value will result in the text always fitting in the boundaires. float scale = Math.Min(xScale, yScale); // Figure out the location to absolutely-center it in the boundaries rectangle. int strWidth = (int)Math.Round(size.X * scale); int strHeight = (int)Math.Round(size.Y * scale); Vector2 position = new Vector2(); position.X = (((boundaries.Width - strWidth) / 2) + boundaries.X); position.Y = (((boundaries.Height - strHeight) / 2) + boundaries.Y); // A bunch of settings where we just want to use reasonable defaults. float rotation = 0.0f; Vector2 spriteOrigin = new Vector2(0, 0); float spriteLayer = 0.0f; // all the way in the front SpriteEffects spriteEffects = new SpriteEffects(); // Draw the string to the sprite batch! Color color; if (clicked &amp;&amp; mouse.LeftButton == ButtonState.Pressed) { color = Color.Silver; } else { color = Color.White; } spriteBatch.Begin(); spriteBatch.DrawString(font, text, position, color, rotation, spriteOrigin, scale, spriteEffects, spriteLayer); spriteBatch.End(); } } </code></pre> <p>Before coding the Menu class, I was just using <code>Draw()</code> for each button and was working fine. Then, something went wrong and I don't know why but I can't display <code>optionsMenu</code>. What am I doing wrong. Can someone tell what's wrong with this code and why I can't display the menu?</p>

    1. COfrom what i see you are calling `DrawButton` function only if buttons are "clickable"... are they? also try avoiding calling `spriteBatch.Begin();` and `spriteBatch.End();` to many times. use them only once in your main Draw function, and between them call your other draw functions.

    2. COalso this one is suspicious: `if (!menuOn) return;` ... you have to go step by step in debugger...

    3. COWhat do you mean with "I can't display `optionsMenu`"? Are you already drawing another menu? Are you properly calling `optionsMenu.Draw`? The first thing to do, as *Davor* wrote, is use the debugger: try to add some breakpoints.

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.
