Multi Select Rows in Webdynpro ALV with out using ctrl key.

[kutjohn]

Hi all,

I saw many people asking how to do a multi-selection on a webdynpro ALV without using ctrl key.

First of all it isn't a straight forward method but does the job.

So if you are in a situation where you have to do multi-selection without ctrl key, this document should help you.

Before I start this document I assume that you know how to create an ALV in webdynpro.

Step 1:Create an ALV and while initializing the ALV ( In my case its in WDDOINIT method ) set the selection mode as MULTI.

Step 2:Create a global table as an attribute to the controller.

GT_INDEX is of type ZINDEX_T

ZINDEX_T has the line type ZINDEX_S

and ZINDEX_S has the structure:

Step 3:Implement the event handler method on_lead_select of the ALV

Step 4:Write the following code in the method.

DATA: ls_index TYPE zindex_s,

         lv_index TYPE i.

   DATA lo_nd_table_node TYPE REF TO if_wd_context_node.

   lo_nd_table_node = wd_context->get_child_node( name = wd_this->wdctx_table_node ).

   READ TABLE wd_this->gt_index WITH KEY idx = r_param->index TRANSPORTING NO FIELDS.

   IF sy-subrc = 0.

     DELETE wd_this->gt_index INDEX sy-tabix.

   ELSE.

     CLEAR ls_index.

     ls_index-idx = r_param->index.

     APPEND ls_index TO wd_this->gt_index.

   ENDIF.

   LOOP AT wd_this->gt_index INTO ls_index.

     lv_index = ls_index-idx.

     lo_nd_table_node->set_selected(

       EXPORTING

         flag  = abap_true    " Value with Which Property Is to Filled

         index = lv_index    " Index of Context Element

     ).

   ENDLOOP.

Now you go and click on the rows required without pressing ctrl key to select it and click again to deselect it.

Thank you.
