    <p>I have a main form called mainForm - this runs my entire app. In this form I create other forms like this:</p> <pre><code>...... ...... Form[] formMessage = new Form[10]; int formNumber = 0; System.Windows.Forms.Button btnCancel; System.Windows.Forms.Button btnClose; System.Windows.Forms.Label lblTimer; System.Windows.Forms.Button btnOK; System.Windows.Forms.Panel panel1; System.Windows.Forms.Label lblMessage; System.Windows.Forms.PictureBox pictureBox1; System.Windows.Forms.Label lblTitle; ...... ...... public void CreateForm(Form form2) { this.btnCancel = new System.Windows.Forms.Button(); this.btnClose = new System.Windows.Forms.Button(); this.lblTimer = new System.Windows.Forms.Label(); this.btnOK = new System.Windows.Forms.Button(); this.panel1 = new System.Windows.Forms.Panel(); this.lblMessage = new System.Windows.Forms.Label(); this.pictureBox1 = new System.Windows.Forms.PictureBox(); this.lblTitle = new System.Windows.Forms.Label(); // ........ // // lblTimer // this.lblTimer.AutoSize = true; this.lblTimer.BackColor = System.Drawing.Color.Transparent; this.lblTimer.Font = new System.Drawing.Font("Tahoma", 9.75F, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, ((byte)(0))); this.lblTimer.Location = new System.Drawing.Point(9, 120); this.lblTimer.Name = "lblTimer"; this.lblTimer.Size = new System.Drawing.Size(0, 16); this.lblTimer.Visible = Show_Timer; this.lblTimer.TabIndex = 4; form2.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F); form2.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font; form2.BackColor = System.Drawing.Color.FromArgb(((int)(((byte)(224)))), ((int)(((byte)(224)))), ((int)(((byte)(224))))); form2.ClientSize = new System.Drawing.Size(400, 142); form2.ControlBox = false; form2.Controls.Add(this.pictureBox1); form2.Controls.Add(this.panel1); form2.Controls.Add(this.btnOK); form2.Controls.Add(this.lblTimer); form2.Controls.Add(this.btnCancel); form2.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None; form2.Opacity = 0.98; form2.ShowInTaskbar = false; form2.StartPosition = System.Windows.Forms.FormStartPosition.CenterScreen; form2.Tag = formNumber; form2.Paint += new System.Windows.Forms.PaintEventHandler(this.MyMessageBox_Paint); } private void FNeventTrigger(System.Object sender, System.EventArgs e) { formMessage[formNumber] = new Form(); CreateForm(formMessage[formNumber]); formMessage[formNumber].Show(); formNumber++; if (formNumber == 10) formNumber = 0; } public void lbl_timer_UpdateText() { this.lblTimer.Text = newText } </code></pre> <p>I use the FNeventRigger to create my form, and I can have upto 10 of them open at each given time - I use this for showing count down timers.</p> <p>The problem I have is how do I show the count down timer of each form? If I use : this.lblTimer.Text = newText, then only the newest form that was opened displays the correct timer.... the other forms lblTimer.Text stop functioning.</p> <p>Is there a way to address all the lblTimer.Text on all forms opened on the array?</p> <p>Thanks,</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.
