hi,
I have a requirement where i have 2 columns in a table .. one should be read only and the other should be edittable... so i have inserted two cell editors of input field type..and made one as read only and the other one not read only.
but wen i run the application..both are displayed as readonly...
please help.

Hi Anurupa,
The node which you are binding with table UI may not have any element thats why you are getting blank/disabled table. Try adding a element (may be blank) to this node and then run the application. You should see the desired result now.
If you need the code for adding element in a node, let me know.
Hope it helps.

If you don't have any data to display then it will be disabled.
here is the code to add one record to the table.
data: lr_node type ref to if_wd_context_node.
data: ls_stru type <node type >
lr_node = wd_context->get_child_node( '<childnodename>' ).
lr_node->bind_element( new_item = ls_stru ).

Hi Anurupa,
For testing, you can write this code in your WDDOINIT method. But for real time scenario, I assume user is allowed to enter data in this table so you can create a button something like 'Add Row'. and then write following line of code in action of 'Add Row' Button. Please note that 'node_name' is the name of the node u would have actually bind your table with.
////////////////
DATA:
node_tab TYPE REF TO if_wd_context_node,
elem_tab TYPE REF TO if_wd_context_element.
node_tab = wd_context->get_child_node( <node_name> ).
elem_tab = node_tab->create_element( ).
node_Tab->bind_element( new_item = elem_tab SET_INITIAL_ELEMENTS = abap_false ).
//////////////
Hope it helps.

Hi Anurupa,
At First the Table will not have any values.So the Table will display as Blank only.
So what you have to do is, you have to add blank rows to that table and Bind it.Then only it will consider that the Table is having Values and then the editable field will be visible.
Try this Codings,
DATA lo_nd_table TYPE REF TO if_wd_context_node.
DATA lo_el_table TYPE REF TO if_wd_context_element.
DATA lt_table TYPE wd_this->elements_table.
DATA ls_table TYPE wd_this->element_table.
lo_nd_table = wd_context->get_child_node( name = wd_this->wdctx_table ).
do 5 times.
clear ls_table.
append ls_table to lt_table.
enddo.
lo_nd_table->bind_table( lt_table ).

Web Dynpro is a Stateful Application, so the data do not get vanished if you navigate to another view and come back.
This you have to achieve through coding, while navigating back to the first view, in the first view there is Inbound plug and a method is generated for the inbound plug.
You can write code to make the value to blank in the Inbound plug method

Actually this is not entirely accurate. Web Dynpro is of course Stateful and by default Views lifetimes continue even after they are no longer visible. However there is a setting on the View Property Tab where you can control this.

If you set the Lifetime to "when visible" all local context nodes and attributes of the view will be released as soon as the view is no longer visible. Keep in mind that if your context nodes are bound from and external controller, this data will still be retained.
Hi
Populate the values in your table and check, i think it will work

Check your root container is enabled or disabled first?
then your table's enable and read only property ?
