Read input from Dynamically Controls

sois · July 20th, 2007, 07:27 AM

Hello,

I have created some input maskedTextBoxes dynamically with the code below.

But now I have to calculated the sum from these input's.
But I don't now how to read these values out of these dynamically created controls?

All info is welcome,

public byte aantalMeetingen;

private void button1_Click_1(object sender, EventArgs e)
{
     flowLayoutPanel1.Controls.Clear();

     aantalMeetingen = Convert.ToByte(mskAantalMeetingen.Text );
      if (aantalMeetingen <= 15)
      {
          for (byte i = 0; i < aantalMeetingen; i++)
          {
               Label newLabel = new Label();
               newLabel.Name = "lblInput" + Convert.ToString(i);
               newLabel.Text = "Input " + Convert.ToString(i + 1) + " : ";
               newLabel.Width = 55;
               newLabel.Left = 5;
               newLabel.Top = i * 12;

               flowLayoutPanel1.Controls.Add(newLabel);

               MaskedTextBox newMask = new MaskedTextBox();
               newMask.Name = "mskInput" + Convert.ToString(i);
               newMask.Mask = "00000";
               newMask.Left = newLabel.Left + newLabel.Width + 5;
               newMask.Top = newLabel.Top;
               newMask.Width = 40;
               flowLayoutPanel1.Controls.Add(newMask);

               flowLayoutPanel1.FlowDirection = FlowDirection.LeftToRight;

            }
         }

    }

Thanks,

Francois

I think the easiest way is to loop over the Controls from the flowLayoutPanel1 and then check the name of the control.

Something like this:
foreach (Control control in flowLayoutPanel1.Controls)
{
    if (control is MaskedTextBox)
    {
        MaskedTextBox mskInput = (MaskedTextBox)control;
        MessageBox.Show(string.Format("Name: {0} - Value: {1}", mskInput.Name, mskInput.Text));
    }
}

Greetz,

Geert

If you overrode the CreateChildControls() method and know the naming convention of the controls you can access this way (granted you added to a placeholder).

Code:

for (byte i = 0; i < aantalMeetingen; i++)
{
    MaskedTextBox newMask = flowLayoutPanel.FindControl(string.Format("mskInput{0}", Convert.ToString(i)));

    if (newMask != null)
    {
        // do stuff here;
    }
}
