Basically you need to create a SearchContainer and optionally (recommended) a DisplayContext.
I do it like this:
Create the Searcontainer in the render phase of the MVC Portlet module and put it in the request:

String orderByType = ParamUtil.getString(liferayPortletRequest, getOrderByTypeParam(), "asc");
String orderByCol = ParamUtil.getString(liferayPortletRequest, getOrderByColParam(), "[myDefaultOrder]");

thank you so much, you really helped me
but i have a few more question
do i have to override methods in "MyManagementToolbarDisplayContext" to make changes happend like ordering "asc" or "desc". And how do i know which method i have to override?
i use searchContainer tag in my .jsp file to display the grid. How can i change the display of the grid depending on the selected option i choose in clay management toolbar to e.g "filter by name"?
An i have a question to this code snippet. sry but i don't understand how to use this related to clay management toolbar and what is the return type of this method?
And my last question, in clay management tool i have a tag named "getSortingURL" for what do i need this

To 1: The best you can do is to look into the Liferay source code:
Your DixplayContext most likely extends "SearchContainerManagementToolbarDisplayContext" and that extends "BaseManagementToolbarDisplayContext". Find the methods you can override in these classes.
getSortingURL() is also defined there.
In getNavigation(): Look at the parameters that are passed from the ManagementToolbar and use the [My]LocalServiceUtil (created by Service Builder) to get your entities. Finally put the results in the SearchContainer.

Thank you so much
i tried to sort the grid. But when i get the Params from the clay management toolbar, the sorting order is always "asc".
in MyManagementToolbarDisplayContext.java i have overwritten the getSortingOrder as follow
But everytime i refresh the site or press on the "sorting direction" button in clay management toolbar, i always get the output
how can i pass the current value to .jsp?

For me it works like this:
When getNavigation() is called I fill my List accordingly to the set filter. The List is like:
BTW: If someone can please explain why we need to set the Comparator on the SearchContainer AND sort the List manually. Maybe there's a more efficient way to achive the sorting...

Thank you for your answer.
I got the asc/desc order by creating a Comparator object like this:
and in searchcontainer tag i user LocalserviceUtil as follow:
In ManagementToolbarDisplay i got the methods which i get the column name and asc and desc String.
in jsp i switch the boolean var depending on the value i got from ManagementToolbarDisplay.
I have an other question, when i got the Filter name returned by getNavigator, how i know which column i have to choose. When i use
and should i create get-Methods in -service to find the columns?
I got the asc/desc order by creating a Comparator object like this:
boolean asc = false;
OrderByComparator<entityname> obc = OrderByComparatorFactoryUtil.create("EntityName",columnName,asc);</entityname>and in searchcontainer tag i user LocalserviceUtil as follow:
<... results="<%=LocalServiceUtil.getEnties(searchContainer.getStart(), searchContainer.getEnd(), obc)%>"/>In ManagementToolbarDisplay i got the methods which i get the column name and asc and desc String.
in jsp i switch the boolean var depending on the value i got from ManagementToolbarDisplay.

You can get the "navigation" from the request URL with
String navigation = ParamUtil.getString(liferayPortletRequest, getNavigationParam(), "all");
