When the control sets the Disabled = "disabled" attribute, the background cannot obtain the modified value.

<Input id = "text1" type = "text" Disabled = "disabled"/>

Because the Disabled = "disabled" of the control is disabled, there are two solutions for the background to get the modified value:

1. Since the modified value cannot be obtained only when the control is disabled, follow this idea. before modifying data to the database in the background, set the disabled attribute to false, after obtaining the control value

The disabled attribute is set to true.

2. Set the control property to readonly = "readonly" and read-only. In this case, the control value cannot be modified at the foreground, and the control value can be obtained at the background.
