sort table columns

[Former Member]

Hey!

I got a table with some cols like Name, Changed, Status.

This resolves in a lot of rows, and it whould be perfect if the user could sort the rows after wich tableheader that was pressed.

I.E. a user press the column Name, it gets sorted on names, or if Changed is pressed, then its gets sorted on the dates.

Anyone got any clue of how this is possible?

Thank you for your answere.

Now i have copied the TableSorter.java in the right folder in the navigation, and created a Context Attribute.

My question now is how to set the context attribute as a TableSorter type?

Hallo Kristoffer,

by default the TableSorter automatically makes all table columns sortable (i.e. all context attributes). You just have to use the first constructor which does not have the String array parameter (IDs of sortable columns).

public static void wdDoModifyView(
   IPrivateWork wdThis, IPrivateWork.IContextNode wdContext, com.sap.tc.webdynpro.progmodel.api.IWDView view, boolean firstTime)
  {
    //@@begin wdDoModifyView
    if (firstTime) {
      IWDTable table = (IWDTable) view.getElement("CustomerTable");
      wdContext.currentContextElement().setCustomerTableSorter(
        new TableSorter(table, wdThis.wdGetSortCustomersAction(), null));
    }
    //@@end
  }

Hi,

you created Context attribute for table sorter.

see the properties of that context attribute-> select Java Native type Radio button-> Browse (give TavleSorter) it will automatically display-> the given path(FOlder structure) and TableSorter (ie. com.abc.xyz.TableSoret) select this as type.

rest is in implemetation tab(Source code)

hope this solved your problme

Thank you for all your help.

I have managed to set the context type as a TableSorter, but when i compile i get alot of error from the TableSorter.java file.. Isnt it any classfile i also should include? cause the TableSorter doesnt deploy without a bunch of warnings and errors.

Hi,

1)create a context valueattribute in the viewcontex and assign the the following type:

com.sap.tc.webdynpro.tests.utils.TableSorter

2)create a Action in your view for example:sortbyDate

3)assign this action to the table column properties that has to be sorted: Event / onAction sortbyDate

4) go to the implementation tab of your view controler and assign this code to the Action onActionsortbyTable:

wdContext.currentContextElement().getTableSorter().sort(wdEvent, wdContext.nodeDeMaintenenceOverview()); this sorts all elements in the specified valuenode(assigned to the table)

First do this:

1.import the Tablesorter src/packages...

2. Switch to the Context tab page.

3. Using the secondary mouse button, click Context, choose New → Value Attribute, enter TableSorter as name, and confirm by pressing Finish.

4. Select the value attribute TableSorter and choose the type property in the lower window in the Properties tab.

5. Click the pushbutton …, choose Java Native Type and enter com.sap.tc.webdynpro.tests.utils.TableSorter. Confirm choosing OK.

via this example code you can access the sorter:

if (firstTime) {

IWDTable table = (IWDTable) view.getElement("ShoppingBasket");

wdContext.currentContextElement().setTableSorter(

new TableSorter(table, wdThis.wdGetSortAction(), null));

}

and:

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

HI,

Refer this web log

/people/bertram.ganz/blog/2006/03/07/enhanced-web-dynpro-java-tablesorter-for-sap-netweaver-04s

I worked for Copmany code Bapi

1) In a table i displayed Company code (1st Cloumn) and Company Name (2nd Column) by excuting bapi in component controller

2) in View

public static void wdDoModifyView(IPrivateVI_TCompareView wdThis, IPrivateVI_TCompareView.IContextNode wdContext, com.sap.tc.webdynpro.progmodel.api.IWDView view, boolean firstTime)

{

//@@begin wdDoModifyView

if (firstTime) {

IWDTable table = (IWDTable) view.getElement("CompanyTable"); <b><----- [CompanyTable Table UI Name]</b> wdContext.currentContextElement().setSortCompanyName(

new TableSorter(

table,

wdThis.wdGetSortByCompanyNameAction(),

null));

}

//@@end

}

//@@begin javadoc:onActionsortByCompanyName(ServerEvent)

/** Declared validating event handler. */

//@@end

public void onActionsortByCompanyName(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )

{

//@@begin onActionsortByCompanyName(ServerEvent)

wdContext.currentContextElement().getSortCompanyName().sort(

wdEvent,

wdContext

.nodeBapi_Companycode_Getlist_Input()

.nodeOutput()

.nodeCompanycode_List());

//@@end

}

hope this solves your problem
