[Former Member]

This document will walk you through :

The concept of Enabling/Disabling a web dynpro UI-Element using the UI-element property "Enabled".

*********************************************************************************************************************************************************************

Assumption :

    1. You have created a web dynpro application .

    2. You have created the UI elements "Field1" in the view , which you have to enable/disable .

Procedure :

   Step 1 : Create a Attribute in the context of the view with type "WDY_BOOLEAN" lets say i have created "field1_enabled".

   Step 2 : Bind the property "Enabled" of the Field1 with "field1_enabled" (context attribute created in step 1 ).

   Step 3 : Now based on your requirement , place the below code in the appropriate method for enabling the Field1 .

                 DATA lv_field1_enable TYPE wd_this->element_context-field1_enabled.

                 lv_field1_enable = abap_true.            " Enable field1

                 lo_el_context->set_attribute(

                 name = `field1_enabled`

                 value = lv_field1_enable ).

Step 3 :  Same way place the below code in the appropriate method for disabling the field1

                DATA lv_field1_enable TYPE wd_this->element_context-field1_enabled.

                lv_field_enable1 = abap_false.          " Disable  field1

                lo_el_context->set_attribute(

                name = `field1_enabled`

                value = lv_field1_enable ).
