    <p>In my minesweeper game I need to dynamically create controls in order to shift between easy - medium - hard. Let's say for the sake of the question hard consists of 100 buttons.</p> <p>This is how I'm creating them:</p> <pre><code>this.SuspendLayout(); //Creating so many things that I assume it would be faster to suspend and resume. foreach (string i in playingField) { Button button = new Button(); button.Name = i; button.FlatStyle = System.Windows.Forms.FlatStyle.Popup; button.Margin = new Padding(0); button.TabIndex = 0; button.Location = new System.Drawing.Point(3, 3); button.Size = new System.Drawing.Size(25, 25); button.BackgroundImage = blockImage; //##// button.MouseDown += new System.Windows.Forms.MouseEventHandler(this.GetUnderSide); button.UseVisualStyleBackColor = false; minesPanel.Controls.Add(button); //Adding the controls to the container } this.ResumeLayout(); //Refer to above. Correct me if I'm wrong please. </code></pre> <p>As you can see I'm creating all of the controls through a for loop, and then adding them. It results in each button being painted once at a time. I also tried <code>name.Controls.AddRange(arrayButtons)</code> and it still resulted in the same problem. Individual painting.</p> <p>What I need is a way to create all items, and then paint them ALL after, like painting a single bitmap with <code>DoubleBuffered</code>, but alas, that doesn't work either.</p> <p>Furthermore, I have tried this:</p> <pre><code> protected override CreateParams CreateParams { get { // Activate double buffering at the form level. All child controls will be double buffered as well. CreateParams cp = base.CreateParams; cp.ExStyle |= 0x02000000; // WS_EX_COMPOSITED return cp; } } </code></pre> <p>Which kind of works. It only works on application startup. However, given that I will be changing grid sizes and adding more controls at runtime, it is not a viable option. </p> <p>I've been told it's as easy as using the methods in the <code>Graphics</code> class. Problem is, I don't know where to start. </p> <p>If anyone could provide some help on getting all my controls to be painted at the same time, that would be great.</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.
