Question

I have some DomainUpDown controls in my application. The behaviour is set like this:

• Normal: Each control can individually goes Up/Down (Change selected item)
• Special: If a check box is checked, Up/Downing the first control will cause the other controls to change as well

Now there are some cases that I want some of the controls to be disabled by setting Disabled = true. I did it, but in this case changing the selected item of the first control will cause the other disabled controls to change the selected item as well.

Is there a way to completly disable a control so it does not accepts something like control.Text = "bla bla" ?

P.S: I need not to hide the control!

Answer 1

One way:

You can hold a list of Textbox.Text values, which will hold entries for all of your textboxes.

Upon OnTextChanged:

• if your textbox is enabled – update it’s text property and store it up in the list.

• if your textbox is disabled – set it’s text property to the last value you had in your list.

You can use a Dictionary or anything similar that contain KeyValuePair objects.
