David Goldberg posted an example on how to use tooltips with NumericEditArray controls which really helped me out. I posted a complete example method based on his code and he asked me to post it here.

David Goldberg's original Post :<div>Hi Adam,</div><div> </div><div>Yes, you can set tooltips for each item in a <strong>NumericEditArray</strong>. The following instructions assume you are using C#.</div><div> </div><ol><li>Drag a ToolTip from <strong>Common Controls</strong> onto the form with the <strong>NumericEditArray</strong>.</li><li>Add the following code to your Form, after InitializeComponent()</li></ol><blockquote><blockquote>int i = 0;foreach (Control c in numericEditArray1){toolTip1.SetToolTip(c, "hello " + i.ToString());i++;}</blockquote></blockquote><div>--
</div>It wasn't clear to me whichconstructor I needed to use to create toolTip1 in this example. I gotit working and decided to post my code. This is a complete listing ofa method that loads a NumericEditArray control called adcValues with 10values and the assigns the tool tips. The empty ToolTip constructor works fine. Maybe it's obvious but I thought I would post this anyway. private void button1_Click(object sender, EventArgs e) { int i = 0; int num_adcs = 10; double adcChannels = new doublenum_adcs; // Fill up an array with some generic values for (i = 0; i < num_adcs; i++) { adcChannelsi = i * 500; } // // -- START OF OPTIONAL SECTION. // // Just trying to format the NumericEditArray controls so that I don't need scroll bars to // see all the values. I fixed the max at 20 just because it seemed like a good value at // the time. Must have been as big as I wanted to make the dialog the control was in or // something.Pretty clumsy but it seems to work all right // // Make table long enough to not need scroll bars adcValues.Height = adcValues.ItemTemplate.Height * (num_adcs + 1); // Add more controls if needed if ((num_adcs > 1) && (num_adcs < 20)) { adcValues.ScaleMode = ControlArrayScaleMode.CreateFixedMode(num_adcs); } else if (num_adcs < 1) { adcValues.ScaleMode = ControlArrayScaleMode.CreateFixedMode(1); } else { MessageBox.Show(string.Format("Problem with adcValues. Can onlydisplay 1-20. Only updating up to 20. Sent = {0}", num_adcs)); return; } // -- END OF OPTIONAL SECTION // Assign the array to the NumericEditArray control. It will grow as needed. adcValues.SetValues(adcChannels); // Create a ToolTip object without worrying about assigning it to anything yet. ToolTip toolTip1 = new ToolTip(); i = 0; // Add the tool tips now to each value in the NumericEditArray control. foreach (Control c in adcValues) { toolTip1.SetToolTip(c, "hello " + i.ToString()); i++; } }
