Generic table Filtering in webdynpro

[venkatakalyan_karanam]

I have some screens consists of some tables ,I have to do the filtering for all the tables not in the view controller class,I need a generic java class that is useful for filtering in all the tables by just calling a method in that class.

I should not connect to th backend while filtering,So I created one extra node for backup the data that is same as table datasource.

Can anybody is having the TableFilter.java like TableSorter.java Pls send me to venkatakalyan.k@gmail.com

In this regards I request you all to give help with detailed explanation.

Hello Venkat

I ll suggest you to trigger an action (Have some button for this) whenever you want to save data changed by the user in check boxes. This way, you wont have to worry about data loss. Please try this once and check the result if it works.

I hope it ll work.

Hi Kalyan,

Here i am sending one file as well as some guidelines for sorting the table.I hope this may helps u.

I am sending that File to ur Gmail account.

Plz find that file and let me know if u hav any doubts.

Plz go through the instructions after reading the file.

1. Create a action in the View say sortPernrData

2. Add the java file TableSorter.java file to ur src folder.

Folder structure is com.sap.tc.webdynpro.tests.utils

3. Create a context attribute say TableSorter in the View's context.

Its type should be of TableSorter.

4. Code to be written in wdDoModifyView() method of the View

IWDTable objTable = null;

try

{

objTable = (IWDTable)view.getElement("DetailsTable");

if (firstTime)

{

wdContext.currentContextElement().setTableSorter(new TableSorter(objTable,wdThis.wdGetSortPernrDataAction(),null));

}

}

5. Code to be wriiten in the action wdGetSortPernrDataAction()

wdContext.currentContextElement().getTableSorter().sort(wdEvent,wdContext.nodeZpernr());

Lavanya

Hi Kalyan

I was nt able to understand your doubt completely.

Is your a case, where in you want a filter on a column with check-box as table cell-editor ? Or you mean to ask if filtering is done on some other column other than the check-box column, then in such case you fear user changes might be lost, is it ?

In former case, I dont see any need of a filter on a check box column...

In latter case, I think it depends on the way you have used to fetch the check-box information. If you have some action bound to the toggle event property of check-box where in you save the user data, then chances are less that you might lose this data. Please try this approach in case you are losing your data.

Also feel free to ask doubts, if any.
