ASPxTextBox - When an editor is disabled on the client side, its Text is cleared after a postback

In IE7 Compatibility Mode ASPxComboBox does not have a value on a callback on the server side if it is disabled on the client side

created 10 years ago (modified 10 years ago)

Hi,

In IE11, ieCompatibilityVersion="7"  cannot get value of AspxComboBox on server side if combo box is SetEnabled(false).
Working fine if ieCompatibilityVersion="edge".

Thank you

      Hello,
      In fact, the browser collects input values of enabled controls only. As a result, when ASPxComboBox is disabled by SetEnabled(false), it does not receive a value from the client on the server side. Similar questions were discussed in the following tickets:
      B202991: ASPxTextBox - When an editor is disabled on the client side, its Text is cleared after a postback
      B202968: ASPxTextBox - Text set by the SetText method is not persisted on postbacks if the text box is disabled
      Q276621: ASPxTextBox ClientEnabled="false" loses value after postback
      However, you said that this behavior only occurs in IE with ieCompatibilityVersion="7" and does not occur in IE 11. It seems strange, because this behavior is expected and should be applicable for all browsers.
      Would you please provide me with a sample project where a value of ASPxComboBox is available on the server side when it is disabled on the client? I would like to research this issue in greater detail.

          Here is example. Select value in first combo. Than click button. Works in all browsers except in IE, when is ieCompatibilityVersion="7".
