WD ABAP: How to get the contents of selected table lines?

Question

Hi,
I'm trying to figure out how to get the contents of table lines back from the UI. I display a table with several lines of data. The user selects some rows. I want to move the contents of the selected rows to another table. I have a context attribute, say DATA, with attributes FIELD1... FIELDn, using a DDIC structure. These are bound to the table UI element and the corresponding table columns. To get the selected rows, I use wd_context->get_selected_elements(). This works, but what I get from this method is references to if_wd_context_element. How do I know which row (row number = ?) this corresponds to? And how do I get the actual data? I want a structure with FIELD1 = value1 FIELD2 = value2 etc. My context attributes FIELD refer to table columns, but I'm looking for the table line...
Can somebody help me?
Thanks,
Ira

Hi Ira,
wd_context->get_selected_elements() returns WDR_CONTEXT_ELEMENT_SET which is a table type of IF_WD_CONTEXT_ELEMENT. You can loop through the WDR_CONTEXT_ELEMENT_SET, get into variable say node_elelement which is of type ref to If_Wd_Context_Element. Then you could use the method GET_STATIC_ATTRIBUTES of If_Wd_Context_Element which returns a structure with values of all the attributes in the selected row.
If you need the row number, while populating the node you could have an additional attribute called rowno and populate it correctly. When you select the data using method GET_STATIC_ATTRIBUTES, you would get the appropriate row number.
