dynamically changing UI element 's binding

[former_member196517]

Hi Frnds,

how can we change a binding of a UI element at runtime. I guess method is REPLACE_PROPERTY_BINDING of CL_WD_UIELEMENT. Does anyone have any example for this..

Thanks

Hi Anuj,

Check out these standard examples,

WDR_TEST_DYNAMIC ,WDR_TEST_DYNAMIC1 upto 4.

This will definitely help you.

Hope this will work!!!

Hi Anuj,

You can find the example of dynamically changing the text of the label in the below link:

Hi Anuj,

the method REPLACE_PROPERTY_BINDING has 4 parameters ie 3 Importing and 1 Returning.

OLD_BINDING : Pass the current binding information. This information you will get from the wizard ie Elem_****

PATH : Just pass the attrubute path for which element you want to get it. this also can get through wizard. Here access the new context element.

BINDING_TYPE: CO_ATTRIBUTE_BINDING( Attribute Binding),

CO_NODE_BINDING(Node Binding)

CO_MULTI_ATTRIBUTE_BINDING(Multiple Attribute Binding)

CO_MULTI_NODERANGE_BINDING(Multiple Node Range Binding)

Hi Anuj.

Though I would reconsider the design, cause I do not think it is the best way to change bindings of UI elements to context nodes dynamically at runtime, you should take a look at these methods:

REMOVE__DDIC_BINDING

GET__DDIC_BINDING

SET__DDIC_BINDING

as the above mentioned method REPLACE_PROPERTY_BINDING is protected.

Hope this helps a bit.

Hello Anuj,

Please have a look at this weblog. In the lower area you find a description about how to bind attributes of view elements to the context dynamically.

Hi Sascha,

I dont think so that these method will help because UI element is not binded to any DDIC rather it is to a attribute which gives me a freely search help , but in a case if application is called from some other app i dont want to show that F4 help , thats why at runtime i want to change binding of a UI element's property. Also i think REPLACE PROPERTY BINDING will help but i am not sure how to pass old binding and new binding elements to it.

Any help...
