    <p>I am creating a few pictureboxes dynamically, then assigning the following:</p> <pre><code>// class variable public String PaintLabel; // private void Form2_Load(object sender, EventArgs e) //begin loop this.PaintLabel = serialno; Shapes[i].Paint += new PaintEventHandler(ctl_Paint); // end loop // my event override private void ctl_Paint(object sender, PaintEventArgs e) { Control tmp = (Control)sender; using (Font myFont = new Font("Arial", 9, FontStyle.Bold)) { e.Graphics.DrawString(this.PaintLabel, myFont, Brushes.LightYellow, new Point(62, 2)); } // using (Font myFont = new Font("Arial", 10)) } // private void ctl_Paint(object sender, EventArgs e) </code></pre> <p>It is supposed to create the picture boxes and write a different serial number on each one. But it ends up writing the last serial number found on all of the picture boxes</p> <p>EDIT:</p> <p>Ok, your solution is very advanced for me. But I have tried to understand it.</p> <p>I have added your piece of code into mine.</p> <p>Then changed my picture box array as follows</p> <pre><code>MyControl[] Shapes = new MyControl[Num_Picbox]; </code></pre> <p>In my loop I then did the following</p> <pre><code>Shapes[i].SerialNumber = serialno; Shapes[i].Paint += new PaintEventHandler(ctl_Paint); </code></pre> <p>But when I compile and run the code it doesnt draw any serial number on the picturebox.</p> <p>RESOLUTION:</p> <p>Thank your for all your help. I changed your </p> <pre><code>var PaintLabels = new Dictionary&lt;Control, string&gt;(); </code></pre> <p>to</p> <pre><code>Dictionary&lt;Control, string&gt; PaintLabels = new Dictionary&lt;Control, string&gt;(); </code></pre> <p>Which sorted it out, the paint event couldnt see the local variable. </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.
