RowRepeater UIElement in Webdynpro ABAP

[Former Member]

Hello,

I want to create a RowRepeater UI Elements in Webdynpro ABAP and fill a certain number of rows at runtime. I looked at the standard component wdr_test_events -> Row_Repeater View in which there is a node in the context bound to the 'datasource' property of the RowRepeater Element and the node is filled using the supply function which has the following code.:

data l type if_row_repeater=>element_row_repeater_data.

data t type if_row_repeater=>elements_row_repeater_data.

data i type string.

define st.

concatenate `[ Row` i `: Element &1 ]` into l-&1.

end-of-definition.

l-first_line_visible = abap_true.

do 55 times.

i = sy-index.

condense i.

l-element_1 = 'ICON_STATUS_OK'.

st element_2_tv1.

st element_2_tv2.

st element_2_tv3.

st element_2_tv4.

st element_2_in1.

st element_3_tv1.

st element_3_tv2.

st element_3_tv3.

concatenate `RowDescription for row ` i into l-row_description.

insert l into table t.

l-first_line_visible = abap_false.

enddo.

node->bind_table( t ).

It's very hard to understand what this code is doing exactly like the statement:

concatenate `[ Row` i `: Element &1 ]` into l-&1.

like what is the meaning of l-&1?

Any help would be highly appreciated.

Thanks.

Hi,

define st.

concatenate ` Row` i `: Element &1 ` into l-&1.

end-of-definition.

is the macro.So where ever st comes will be replaced with " concatenate ` Row` i `: Element &1 ` into l-&1".

&1 is the placeholder to fill data.

As an example they used this way to fill data.

You can use your own way to fill data.

data l type if_row_repeater=>element_row_repeater_data.

this statement declares a structure of type if_row_repeater=>element_row_repeater_data

data t type if_row_repeater=>elements_row_repeater_data.

this creates a tbale of the same type as above.

define st.
concatenate ` Row` i `: Element &1 ` into l-&1.
end-of-definition.

this is a macro definition in abap

it is using &1 to pass the parameters when you call this macro

using st <paramvalue> this passed paramvalue will replace the placeholder &1 in the macro.

e.g. when you call it using

st element_2_tv1.

the macro will replace this statement like

concatenate ` Row` i `: Element element_2_tv1 ` into l-element_2_tv1.
