How can I set the attribute first_visible_row in a table which I placed on a Web Dynpro?
I need the table to scroll automatically to a specific row depending on a date. So I'm calling a method using this date, but how can I change the attribute of the table?
Thank you!
Follow these steps,
1- Create an attribute with char1 in the view context e.g first_vis_row
2- go to the table properties in view and bind the property first_visible_row to this attribute.
3- NOw go to the wddoinit method of the view...
4- read the internal table and find out the index of the row which you want to set as first row. As in ur case you want a specific date in first row. So read the internal table and findout the index.
5- now write this code, say your attribute name is first row inside node flag1...(you can change it for yoru requirement)
DATA lo_nd_flag1 TYPE REF TO if_wd_context_node.
DATA lo_el_flag1 TYPE REF TO if_wd_context_element.
DATA ls_flag1 TYPE wd_this->element_flag1.
DATA lv_first_row LIKE ls_flag1-first_row.
* navigate from <CONTEXT> to <FLAG1> via lead selection
lo_nd_flag1 = wd_context->get_child_node( name = wd_this->wdctx_flag1 ).
* get element via lead selection
lo_el_flag1 = lo_nd_flag1->get_element( ).
* get single attribute
lo_el_flag1->get_attribute(
EXPORTING
name = `FIRST_ROW`
IMPORTING
value = lv_first_row ).
here change the lv_first_row to the index which you got after raeading the internal table.
suppose it's
lv_first_row = 4.
lo_el_flag1->set_attribute(
EXPORTING
name = `FIRST_ROW`
value = lv_first_row ).
Hope it works.
