Change the layout data type dynamically in standard webdynpro applications

[Former Member]

Hi ,

I am working on standard webdynpro component .My req is

I am having a matrix layout container C1 which consists of two containers c2 and c3 in C1 .

Now individually C2 and C3 are also Matrix layout

And layout data of C2 is matrix head data and C3 is matrix data .

Now I am deleting the c2 by using REMOVE ELEMENT ..But now I am getting an error as c3 should be of matrix head data .

I have done with the following changes in postexit

Please check it and let me know if any problem is there in coding

DATA : LT_MAT_LAY TYPE REF TO CL_WD_MATRIX_LAYOUT.

DATA : LT_MAT_DATA TYPE REF TO CL_WD_MATRIX_DATA.

DATA: LT_MAT_HEAD TYPE REF TO CL_WD_MATRIX_HEAD_DATA.

DATA : LT TYPE REF TO CL_WD_LAYOUT_DATA.

*DATA : VIEW TYPE REF TO IF_WD_VIEW .

DATA : LR_CONT TYPE REF TO cl_wd_TRANSPARENT_container .

LR_CONT ?= VIEW->GET_ELEMENT( 'CONTENT_CONTAINER' ).

Content_container is the C3 container as I discussed in d above case .

As of now I am getting the properties of Content_container properties to lr_cont and even I am manipulating lr_cont .But I want to assign matrix head data to C3 which is now matrix data

This classes are related to matrix layout for ur help

DATA : LT_MAT_LAY TYPE REF TO CL_WD_MATRIX_LAYOUT.

DATA : LT_MAT_DATA TYPE REF TO CL_WD_MATRIX_DATA.

DATA: LT_MAT_HEAD TYPE REF TO CL_WD_MATRIX_HEAD_DATA.

DATA : LT TYPE REF TO CL_WD_LAYOUT_DATA.

Can anyone help me in this .....

Is there is anyother procedure for this ..

Even I checked with configurations which is showing no result for this requirement ..

This behavior is right. c2 and c3 are children of C1. You need to have atleast one Martix head data inside a container. So when you delete c2, you need to change the layout of c3 to Matrix head data.

Easiest way is (assuming lo_tc3 is your c3 and you already have it initialized

data:
   lo_tc3                              TYPE REF TO cl_wd_transparent_container.

 LT_MAT_HEAD = CL_WD_MATRIX_HEAD_DATA=>new_matrix_head_data(
     element = lo_tc3 ).

lo_tc3->set_layout_data(  LT_MAT_HEAD ).
