Table view help required

[Former Member]

hi,

I've a htmlb tableview which gets the data from an internal table which is a data member of a model. I've two column fields in this view which are editable. What are the steps I need to follow in order to get the internal table updated with the values provided by the user in the editable fields of tableview.

could someone please provide me with the steps as to how to achieve this?

Thanks and Regards,

Try this sample code,as it helps you considerably.

local types

*----

types: itabtype type TABLE OF STD1.

types: begin of message_struct,

type type char10,

text type char100,

end of message_struct.

*----

• page attributes

*----

---

addtab TYPE ITABTYPE

addtab_row TYPE STD1

add_flag TYPE FLAG

deltab TYPE ITABTYE

deltab_row TYPE STD1

ITAB TYPE ITABTYPE

iterator TYPE REF TO IF_HTMLB_TABLEVIEW_ITERATOR

message TYPE MESSAGE_STRUCT

STUDENT TYPE STRING

STATUS TYPE STRING

<b>layout</b>

<htmlb:content design="design2003" >

<htmlb:page title="test1" >

<htmlb:form>

<htmlb:tableView id = "tv1"

visibleRowCount = "20"

onRowSelection = "MyEventRowSelection"

selectionMode = "lineEdit"

table = "<%= ITAB %>"

iterator = "<%=iterator %>" />

<htmlb:button id = "save"

text = "Save Changes"

onClick = "myEvent" />

• eventhandler OnCreate

• this handler is called once the page is first created (stateful mode)

• it performs a once-off data initialization or object creation

SELECT * FROM STD1

CREATE OBJECT iterator TYPE STD1ITERATOR.

write the path in the layout of the page view as "//<model class object>/<internal table>"

for example:

<htmlb:tableView id = "matdesctab"

design = "ALTERNATING"

table = "//model/I_MATMAST"

selectionMode = "LINEEDIT"

onRowSelection = "edit" >

This will take the current values in the internal table & write the code to save them on clicking the SAVE button.

oninput processing write code to retrive the values and update your table or use data binding.

for both the methods, search this forum, there are lot of example code.
