Property Value

Boolean

true if controls disabled on the client are forced to submit their values; otherwise, false. The default value is false.

Examples

The following code example demonstrates how to set the SubmitDisabledControls property on a form to true to cause controls disabled by client script to maintain their values after the page posts back to the server. In this example, if you set the SubmitDisabledControls property to false and then click the Post back button, the text in the HTML text box is lost and the HTML check box is no longer selected.

Remarks

Use the SubmitDisabledControls property to specify whether to force controls disabled on the client to submit their values when the page posts back. This allows the disabled controls to preserve their values after the page posts back to the server. When the SubmitDisabledControls property is set to false, controls on the form that have been disabled using client script will not be submitted to the server the next time the page posts back. As a result, any values stored by the disabled controls are lost. To allow the disabled controls to preserve their values after the page posts back to the server, set the SubmitDisabledControls property to true.
